The best insurance against accidents is to abide by the safety regulations. Read and understand this section carefully, before operating the excavator. Every user, however experienced, should carefully read and understand this section and those of the attachments and accessories before taking the excavator into operation. The owner is obliged to inform the operators of these instruction in detail. Keep this manual in the storage place. (See "Keeping the Operator's Manual" in the BEFORE START section.) 1. BEFORE OPERATION 1. Make yourself acquainted with the excavator and be aware of its limits. Read this operator’s manual carefully before starting the excavator.
2. Obey the danger, warning and caution labels on the machine.
3. For your safety, a ROPS/OPG (Top Guard Level I) with a seat belt is installed by KUBOTA. A ROPS: Roll-Over Protective Structure A OPG (Top Guard Level I): Operator
Protective Guards of Top Guard Level I OPG (Top Guard Level I) in accordance with ISO10262 is equivalent in de. nition to FOPS (Falling Object Protective Structure). Always use the seat belt when the machine is equipped with a ROPS/OPG (Top Guard Level I) as this combination will reduce the risk of serious injury or death, should the excavator be upset or falling objects occur. Do not modify any structural members of the ROPS/OPG (Top Guard Level I) by welding, drilling, bending, grinding or cutting, as this may weaken the structure. If any component is damaged, replace it. Do not attempt repairs. If the ROPS/ OPG (Top Guard Level I) is loosened or removed for any reason, make sure all parts are reinstalled correctly. Tighten mounting bolts to proper torque. 4. ROPS meets requirements of ISO 3471. OPG (Top Guard Level I) meets requirements of OSHA 1926·1003/ISO 10262.
5. The seat belt must be inspected regularly and replaced if frayed or damaged.
6. Track can be set at the narrow width 39in. (990mm) and the standard width 49in. (1240mm). (for details see “OPERATION OF TRACK WIDTH CHANGE AND DOZER”) Do not operate in narrow track width 39in. (990mm), it makes risk of the excavator tipping over, operate always in standard track width 49in. (1240mm), except to pass through narrow space on a even ground.
7. Do not use the excavator under the in.uence of alcohol, medication as well as other substances. Fatigue is also dangerous. 8. Check the surroundings carefully before using the excavator or when attachments are being attached. • Pay attention to the overhead clearance with electric wires.
• During excavator use do not allow any persons within the working range. 9. Do not allow other persons to use the machine before having informed him on the exact operation and work instructions, and be assured that the operator’s manual has been read and understood.
10. Do not wear baggy, torn or too large clothing when working with the excavator. Clothing can get caught in rotating parts or control elements which can cause accidents or injuries. Wear adequate safety clothing, e.g. safety helmet, safety shoes, eye protection, ear protection, working gloves, etc., as necessary and as prescribed by law or statutes.
(2) Clothing .t for work
(3) Tight seams
(4) Good grip shoewear
(5) Well . tting cuffs
(6) Working gloves
(7) Straw hat
(9) Baggy trousers
(10) Loose cuffs of the shirt
(11) Baggy shirt
(12) Rubber sandals
11. Do not allow passengers to get on any part of the excavator seat throughout operation.
12. Check mechanical parts for correct adjustments and wear. Exchange worn or damaged parts immediately.
13. Keep your excavator clean. Heavy soiling, grease, dust and grass can in.ame and cause accidents or injuries.
14. Use only KUBOTA authorized attachments.
15. Before starting the excavator, be absolutely sure that the excavator has been . lled with fuel, lubricated, greased and undergone other maintenance work.
16. Do not modify the excavator, otherwise it could lead to unforeseen safety problems.
17. Make sure attachments, particulary those utilizing quick attach systems, are securely mounted.
2. STARTING OF THE EXCAVATOR 1. Get into and out of the machine safely. Always face the machine. Always use handrails and available steps and keep yourself well balanced. Do not hold any of the control Ievers and switches. Do not jump on or off the machine, whether stationary or in motion.
2. Start and control the excavator only from the operator’s seat. The driver should not lean out of his seat when the engine is running.
3. Before starting the engine, make sure that all control levers (including auxiliary control levers) are in their neutral positions. Before starting the engine, make sure that the control levers, travel lever, pedals and other control elements are not stuck and can be moved smoothly. If stuck, for example, a lever may fail to return, possibly putting you in danger. If anything wrong is found, immediately pinpoint the cause and correct it.
4. Do not start the engine by jumping the starter connections. Do not try to circumvent using the starter switch, otherwise the engine could start suddenly and the excavator could move.
5. Make sure that the dozer is on the front side. (The dozer must be raised.) If the levers are activated with the dozer on the rear end, the driving direction is in the opposite direction of the drive levers.
6. Do not run the engine in closed or badly ventilated rooms. Carbon monoxide is colourless, odourless and deadly.
7. Keep all safety equipment and covers in place. Replace damaged or missing safety device.
8. Precautions against tipping over. In order to secure safe operation, keep away from steep slopes and embankments. Do not swing the bucket downwards. Lower the dozer during digging. Keep the bucket as low as possible while driving upwards. Turn slowly on slopes (do not fast). Do not keep the excavator near the edges of trenches and banks, as the earth can give away due to the weight of the excavator.
9. Watch out at all times where the excavator is being moved to. Keep an eye out for hindrances.
10. Keep enough distance from trench and bank edges.
• Safety for children Tragedy can occur if the operator is not alert to the presence of children. Children generally are attached to machines and the work they do. 1. Never assume that children will remain where you last saw them.
2. Keep children out of the work area and under the watchful eye of another responsible adult.
3. Be alert and shut your machine down if children enter the work area.
4. Never carry children on your machine. There is no safe place for them to ride. They may fall off and be run over or interfere with your control of the machine.
5. Never allow children to operate the machine even under adult supervision.
6. Never allow children to play on the machine or on the attachments.
7. Use extra caution when backing up. Look behind and down to make sure the area clear before moving.
8. When parking your machine, if at all possible, park on a . rm, .at and level surface; if not, park across a slope. Lower the bucket and dozer to the ground, remove the key place the control lock levers in the locked position from the ignition before you leave.
3.AFTER OPERATION Before leaving the machine, • Bring the excavater on a . rm, . at and level surface.
• Lower the attachments and the dozer blade on the ground.
• Stop the engine.
• Lock all control levers.
• Remove the key.
4. SAFE LOADING AND TRANSPORT OF THE EXCAVATOR 1. Observe all regulations concerning the transport of excavators on public roads.
2. Use adequately long and robust ramps when loading on a truck. (for details see “TRANSPORTING THE EXCAVATOR ON A TRUCK”)
3. Do not change the running direction and to avoid a tipping over, do not try to swing the attachment crosswise to the loading ramps.
4. After loading of the excavator on a truck, engage the swing lock pin. Lower the attachment on the loading plane and release the pressure from the hydraulic system. Block the tracks with blocks and wire down the excavator. After loading the excavator on a truck, tie down the undercarriage of the excavator with a strong steel wire on the truck.
5. Do not brake abruptly with the excavator loaded. Mortal accidents could happen.
6. If the excavator is used to tow another machine, the load must be smaller than the strength of the hook.
7. Do not use hooks on the roof of canopy for lifting the excavator.
Max. drawbar pull at 32.3 kNcoupling hook Max. vertical load at 2.7 kNcoupling hook
5.MAINTENANCE Before doing maintenance work on the excavator, place the machine on a . rm, . at and level surface, Iower the attachments on the ground, stop the engine then remove the key and release the cylinder pressure by actuating the levers. When dismantling hydraulic parts, make sure that the hydraulic oil has cooled down suf.ciently to avoid burns. Start maintenance work carefully, e.g. loosen screws slowly so that oil will not squirt out. 1. Before doing work on the engine, the exhaust system, the radiator and the hydraulics, let the excavator cool down suf. ciently.
2. Turn off the engine at all times when .lling with fuel. Avoid spilling and over.lling of fuel.
3. Smoking is prohibited while tanking and handling the battery! Keep sparks and .re away from the fuel tank and battery. Flammable gases escape from the battery, especially during charging.
4. Do not use or charge the re. llable type battery if the .uid level is below the LOWER (lower limit level) mark. Otherwise, the battery component parts may prematurely deteriorate, which may shorten the battery's service life or cause an explosion. Check the . uid level regularly and add distilled water as required so that the .uid level is between the UPPER and LOWER levels.
5. Read and follow “STARTING WITH AN AUXILIARY BATTERY” in “OPERATION OF THE ENGINE”, when starting with an auxiliary battery.
6. To avoid short-circuiting the battery, always remove the earth cable . rst and attach the plus cable . rst.
7. Keep a .rst-aid box and a . re extinguisher at hand at all times.
8. Do not open the radiator cap before the radiator has cooled down suf. ciently. First loosen the cap to the . rst stop and allow the system enough time to release the remaining pressure. Then loosen the cap completely.
9. Leaking hydraulic .uid has enough pressure to penetrate the skin and cause serious injuries. Leakages from pin holes can be totally invisible. Do not use the bare hand for checking on possible leakages. Always use a piece of wood or cardboard. It is strongly recommended to use a face mask or eye protection. Should injuries occur with leaking hydraulic .uid, contact a doctor immediately. This .uid can cause gangrene or serious allergic reactions.
10. To avoid leakage of battery acid which contains heavy metals, do not throw the battery away.
11. Observe all laws and regulations concerning the disposal of used oil, coolants, solvents, hydraulic . uids, battery acids and batteries.
12. To avoid .re, do not heat the hydraulic components (tanks, pipes, hoses, cylinders) before they are drained and washed.
13. Use a face mask or eye protection to protect the eyes and respiratory system against dust and other foreign particles.
14. Securely support excavator with stands or suitable blocking before working underneath. For your safety, do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered.
15. Do not crawl under the excavator if the excavator is only supported by the boom and arm or the dozer. The excavator can tip over or lower itself due to hydraulic pressure loss. Always use safety struts or other appropriate supports.
16. KUBOTA uses no parts which are lined with asbestos. Do not use these kind of parts even if they can be installed.
17. Fire prevention Excavator and some attachments have components that are at high temperatures under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcing or sparks. The following .re prevention guidelines will help to keep your equipment up and running ef.ciently and keep the risk of .re to a minimum.
• Blow off all accumulated debris near hot engine exhaust components such as turbocharger and exhaust manifold as well as exhaust pipes and muf. er more frequently when working in severe conditions.
• Clean out all accumulated . ammable debris such as leaves, straw, pine needles, branches, bark, small wood chips and any other combustible materials from inside the machine belly pans or lower unit structures as well as from area in proximity to the engine.
• Inspect all fuel lines and hydraulic hoses for wear or for deterioration. Replace them immediately if they begin to leak.
• Examine electrical wiring and connectors frequently for damage. Repair any wires that are loose or frayed before operating the machine. Clean all electrical connections and tighten all electrical connections as necessary.
• Inspect the exhaust system daily for any signs of leakage. Check for broken pipes and muf.er and also for loose or missing bolts, nuts and clamps. If any exhaust leaks or fractured parts are found, repairs must be completed prior to operation.
• Always keep a multipurpose . re extinguisher on or near the machine. Be familiar with the operation of the . re extinguisher.

CONTROL OBSERVATIONS DURING OPERATION • Stop the Engine immediately if: • Sudden increase or decrease in engine rpm's occurs.
• Sudden abnormal noises occur.
• Exhaust gases turn suddenly very dark.
Make following control observations during operation to be sure that everything functions normally.
RUNNING-IN OF THE NEW EXCAVATOR The operation and care of the new excavator in.uences its life span. Your new excavator has been carefully checked and tested before leaving the factory. In spite of this, all movable components must run-in during the .rst 50 work hours. Do not work with full engine rpm's and full loads during this period. It is most important to run-in your excavator properly in order to achieve its full performance and longevity. During the running-in, the following points should be adhered to in all cases. • Do not Work with Full Engine Rpm's or Full Loads during the First 50 Working Hours • Let the engine warm up suf. ciently in the cold season.
• Do not let the engine rev-up more than necessary.
• Oil Change in the Run-in Stage The lubrication oil plays a speci. c and important role during the run-in phase of the excavator. The numerous movable parts are not yet run-in, so many . ne metal particles are generated and cause damage and shorten the lifetime of many components. Pay attention to the oil-change intervals and complete them sooner than later. See the subject "REGULAR CHECKS AND MAINTENANCE WORK" for more details on the oil-change intervals. Seat Belt 3 WARNING To avoid personal injury or death: Always use the seat belt with a ROPS/OPG (Top Guard Level I) protection structure. Adjust the seat to the optimal position and buckle up.

TWO PATTERN SELECTION SYSTEM (TPSS) 3 CAUTION To avoid personal injury: Study control lever pattern A and pattern B. Then choose the one which is most familiar Position the pattern selector lever in either the left side position of the machine (pattern A) or the right side position (pattern B). Familiarize yourself with the pattern selected by operating slowly. Pattern Change Position the pattern selector lever to the desired position.
(1) Pattern selector lever (A) Pattern A (Two Pattern Selection (B) Pattern B System: TPSS)
Lever Position Pattern A Pattern B Attachment Control Lever (Left) A B C D Boom down Boom up Swing left Swing right Arm up Arm crowd Swing left Swing right Attachment Control Lever (Right) 1 2 3 4 Arm up Arm crowd Bucket crowd Bucket dump Boom down Boom up Bucket crowd Bucket dump
OPERATION OF THE BOOM To raise the boom, pull the attachment control lever back. The boom is equipped with a cushion cylinder which helps prevents excavated material in the bucket from falling out. Low hydraulic oil temperature, (e.g. after starting the engine in cold weather) the cushioning function will be effected for a short period of time (approx. 3 to 5 seconds). This condition results from the viscosity of the hydraulic oil and is not a sign of malfunction. The cushion cylinder will operate normally as the oil warms up.
IMPORTANT: • When lowering the boom, make sure that it does not hit the dozer and that the bucket teeth do not touch the dozer.
OPERATION OF THE ARM Pull back the attachment control lever and the arm will be pulled in. To move the arm out, push the control lever towards the front. NOTE: • When pulling in the arm, the movement may stop for a short moment when the arm is in its vertical position. This is caused by the combined load of the arm and bucket moving the cylinder piston away from the hydraulic .ow causing a short delay in the cylinder action, until the .ow catches up with cylinder piston. This is a characteristic of the hydraulic system and is no sign of a malfunction.
OPERATION OF BUCKET To dig using the bucket, move the right attachment control lever from the neutral position left. Moving the control lever right, moves the bucket outwards and dumps its contents.
SWIVEL (UNIT SWING) OPERATION 3 CAUTION To avoid personal injury: When working in groups, always let the others know what you are going to do before you do it. Keep away from the working area. IMPORTANT: • Do not operate the left attachment control lever abruptly from right to left (or vice versa). Because of the law of inertia, this causes an impact load on the swing gear and the swing motor. Additionally, the life of the excavator will be shortened.
• Unlock the swing lock pin before doing swivel operations.
1. Move the control lever to the left and the upper structure will turn to the left.
2. Move the control lever to the right and the upper structure will turn to the right.
BOOM SWING OPERATION 1. Step on the left side of the pedal to swing the boom to the left.
2. Step on the right side of the pedal to swing the boom to the right.

UP AND DOWNHILL TRAVELLING 3 CAUTION To avoid personal injury: Before travelling up and downhill, be sure to be in standard track width [49in. (1240mm)]. When travelling up or down a slope for long periods of time, be sure to engage the swing lock pin. Also engage the swing lock pin when standing on a slope for a long time or the excavator is being transported. While travelling uphill, keep the lower edge of the bucket approx. 8 to 16in. (20 to 40cm) above the ground. Although the KUBOTA excavator will not slip easily because of the tracks, it is safer to let the bucket slide over the ground while travelling downhill. Always choose slow speed for uphill and downhill travelling. [UPHILL TRAVELLING]
PARKING ON A SLOPE 3 WARNING To avoid personal injury or death: When the excavator is parked or left unattended on a slope, be sure to put the bucket on the ground and place all control levers in neutral position, then brace the tracks with drags.
IMPORTANT INFORMATION ON EXCAVATOR OPERATION • Do not try to crush concrete or boulders using side swings with the bucket. Also avoid using side sweeps of the bucket to move earth piles.
• Under all circumstances avoid the following operations:
• Excavation using the gravitational impact of the machine.
• Compacting of gravel or soil using the dropping action of the bucket.
• Excavation using the travelling power of the machine.
• Do not try to drop or shake off soil adhering to the bucket in the manner given in the points below. This can cause damage to the machine. Adhered soil can be shaken off when the bucket is being emptied by moving the bucket out to the maximum stroke of the cylinder. Should this not suf. ce, swing out the arm as far as possible and operate the bucket back and forth.
• Do not hit the dozer with the boom cylinder! Make sure that the boom cylinder does not hit the dozer when doing deep excavation. If necessary swing around so that the dozer is in the back of the machine.
• Pay attention when pulling in the bucket! When pulling in the bucket (for driving or transportation) avoid hitting the dozer.
• Avoid collisions! When moving the excavator, pay attention that the dozer does not collide with obstructions such as boulders etc.. Such collisions shorten the life of the dozer and the cylinder substantially.
• Support the machine correctly! When stabilizing the machine with the dozer, Iower the dozer to engage the full width on the ground.
• If the water or mud level reaches higher than the top of the tracks, the swivel bearing, swivel motor gear and ring gear may be exposed to mud, water and other foreign objects. The excavator must be properly pressure washed after each use. • Thoroughly clean the area around the swivel bearing, swivel motor gear and ring gear to remove foreign objects.
• Inspect the swivel motor oil sump (if equipped) for water contamination. If water is present, refer to operator's manual for lubricant replacement procedure.
• Refer to operator's manual for proper swivel bearing, swivel motor gear and ring gear lubrication procedures.
• Reinstall any protective covering if removed earier.
DANGER To avoid personal injury or death:
• No directional changes should be made when the excavator is on the ramp. Should a change of direction be necessary, drive off the ramp completely and make the turn.
• When driving forwards or backwards onto the truck, or when swinging the upper body, make sure that neither the cabin or the gates of the truck will be damaged.
• When the excavator reaches the point between the ramps and the truck bed, halt and then move very slowly until the excavator reaches the horizontal position.
• Move the excavator onto the truck only with the arm completely pulled in. Otherwise the truck cabin could be damaged when swinging around the upper body.
• Do not jack up the machine using its boom to load or unload the excavator from the truck. Dangerous situation could arise.
• Transporting on a Truck
3 WARNING To avoid personal injury or death: • After loading the machine on the truck, lower the bucket and dozer onto the truck bed. Lock the swing frame with the swing lock pin. Prepare a platform to load or unload the excavator. Take following steps when using ramps. 1. Apply the parking brakes of the truck, and block the drive wheels from both sides.
2. Use mounting brackets to secure the ramp properly. Connect the ramps directly to the truck bed.
3. For additional safety, use blocks or supports under the ramps and the truck bed.
4. Align the ramps and the tracks and then drive the excavator slowly up the ramps. After ensuring that the tracks are completely on the truck bed, swivel the upper body around to the back of the truck.
5. Block the tracks and wire down the excavator.
6. Before unloading, remove the swing lock pin and then raise the dozer and bucket from the truck bed.

PREPARATION FOR OPERATION IN COLD WEATHER 1. Replace engine oil and hydraulic oil with those of viscosities suitable for cold weather.
2. In cold weather, battery power drops, and the battery .uid may freeze if the battery is not suf.ciently charged. To prevent the battery .uid from freezing, be sure to keep the battery charged at least 75% or more of its capacity after operation. To ease next starting, it is recommended to keep the battery stored in closed or heated rooms. If the battery .uid level is too low, do not add after operation, but add with the engine running before the next operation.
3. Add anti-freeze to coolant in the radiator and reserve tank, if the ambient temperature is expected to drop below 0ºC. Mixing ratio of water and antifreeze depends on the expected ambient temperature.
• Mixing ratio between water and antifreeze Ambient Temperature°C –5 –10 –15 –20 –25 –30 –35 Antifreeze % 30 30 30 35 40 45 50 Water % 70 70 70 65 60 55 50
IMPORTANT: • Use permanent anti-freeze or longlife coolant.
• Drain the coolant completely and clean inside of the radiator then . ll with the water and anti-freeze mixture.
• The anti-freeze acts as an anti-corrosive, it is not necessary to add an additive to the water and anti-freeze mixture.
• See “Coolant check” under “DAILY CHECKS” in “MAINTENANCE” for radiator . ll volumes.
PROCEDURE AFTER DONE WORK Clean the excavator thoroughly after work and wipe dry. Otherwise mud and earth on the tracks could freeze if the temperature drops below the 0ºC mark. Operation of the excavator is then not possible. Store the excavator in a dry place; if not possible, store on wooden planks or on mats. If the excavator is kept on damp or muddy ground, the tracks could freeze overnight. Operation of the excavator is then not possible. Furthermore the reduction gear may be damaged. Additionally, the piston rods of the hydraulic cylinders must be rubbed dry. Otherwise severe damage could occur if dirty water seeps through the seals.
3 CAUTION To avoid personal injury: Do not clean the excavator with the engine running. To avoid the danger of exhaust fume poisoning, do not operate the engine in a
closed building without proper ventilation. When storing, remove the key from the starter switch to avoid unauthorized persons from operating the excavator and getting injured. • Should the Excavator be Stored for a Longer Period of Time, Observe Following Procedures: 1. The whole excavator should be cleaned thoroughly and in all cases stored indoors. If the excavator has to be kept outdoors, Iay out wooden planks on even ground, place the excavator on the planks and cover completely.
2. Do an oil change and grease the excavator.
3. Heavily grease the visible sections of the cylinder rods.
4. Remove the battery and store indoors.
5. If it is expected that the temperature will sink below the 0ºC mark, add anti-freeze or drain coolant completely.
IMPORTANT : Wash the excavator after stopping the engine. If you wash the excavator while running the engine, splashing water get into the air cleaner through its intake and cause engine trouble. Carefully, wash and do not splash water over the air cleaner. • Observe Following Procedures when the Machine is to be Operated after Long Storage 1. Wipe off the grease from the hydraulic cylinder rods.
2. Turn on the engine and operate the attachments and the drive mechanisms under no load in order to circulate the hydraulic oil . (If the machine is stored for longer than one month, Do steps (1) and (2) once every month)
Periodic replacement of important component parts To ensure safety in operation, you are strongly requested to inspect and service the machine at regular intervals. For added safety, ask your KUBOTA dealer to replace the following important component parts. These parts are prone to degradation in material or subject to wear and tear with time. It is dif. cult to judge how much they have been affected at regular inspection. It is therefore necessary to replace them with new ones, whether wear is visible or not after a speci.ed time of use. If any of them is found to be worn before the speci. ed use. They must be repaired or replaced the same as other parts. If any of the hose clamps are found deformed or cracked, the hose slamps must also be replaced. For the hydraulic hoses other than the ones to be replaced periodically, inspect them for the following points. If found loose or very worn, tighten and/or replace the hose. When replacing the hydraulic hoses, change their O rings and sealing components with new ones. For replacement of the important parts, contact your KUBOTA dealer. At the following periodic inspections, check the fuel hoses and hydraulic hoses as well. Inspection Interval Check points Daily Checks Oil leak at fuel and hydraulic hose connections and points Every month Oil leak at fuel and hydraulic hose connections and points Damages at fuel and hydraulic hose (cracks, chafing) Every year Oil leak at fuel and hydraulic hose connections and points Interference, deformation, degradation, twist and other damages (cracks, chafing) of fuel and hydraulic hoses

Fuel: • Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below -20°C (-4°F) or elevations above 1500 m (5000 ft).
• Diesel fuels speci.ed to EN 590 or ASTM D975 are recommended.
• No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
BIODIESEL FUEL (BDF) B0-B20 Biodiesel fuels (BDF): mixed diesel fuels containing 20% or less biodiesel can be utilized under the following conditions. IMPORTANT : Concentrations greater than B5 (5%) are NOT approved for common rail engines and engines with aftertreatment device. Such fuel use can cause damage and reduce engine life. A Refueling and handling fuel should be done with caution in order to avoid contact with the fuel and spillage that could create a potential environmental or .re hazard. Wear appropriate protective equipment when refueling. Applicable BDF: 1. Blended diesel fuels containing 6% thru 20% BDF (B6 - B20) which comply with American Society for Testing and Materials (ASTM) D7467 Standard, as revised, can be used without adversely affecting the performance and durability of the engine and fuel system components.
2. Any mineral oil diesel fuel, if used, must conform to ASTM D975 (or the European EN590) Standard, as revised. B100 fuel used to make Biodiesel blended fuels must meet ASTM D6751 (or EN14214) Standard, as revised. The .nal blended fuel B20 must conform to ASTM D7467 Standard, as revised. Straight vegetable oil is NOT allowed in any blended fuel.
3. Allowable blended fuel is mineral oil diesel fuel blended with B100 (i.e. 100% BDF). The blended fuel ratio shall be less than 20% B100 and 80% or more diesel fuel. The B100 source used for Biodiesel blends must be purchased from an accredited BQ-9000 marketer or producer. More information about quali.ed marketer(s) and producer(s) can be found at http://www. bq-9000.org.
Preparation: 1. Before using BDF concentrations greater than B5, you are advised to replace the engine oil, engine oil .lter and fuel .lter with new oil and .lters. For replacement procedures, refer to the “PERIODIC SERVICE” section. Product Warranty, Emission and Other Precautions: 1. The engine emission control system was certi.ed according to current regulations based on the use of non-BDF. When using BDF, the owner is advised to check applicable local and federal emission regulations and comply with all of them.
2. BDF may cause restricted or clogged fuel .lters during cold weather conditions, resulting in the engine not operating properly.
3. BDF encourages the growth of microorganisms which may cause degradation of the fuel. This in turn may cause fuel line corrosion or reduce fuel . lter .ow earlier than expected.
4. BDF inherently absorbs moisture which may cause degradation of the fuel earlier than expected. To avoid this, drain the water separator and fuel . lter port often.
5. Do not use Biodiesel concentrations higher than 20% (i.e. greater than B20). Engine performance and fuel consumption will be affected, and degradation of the fuel system components may occur.
6. Do not readjust the engine fuel control system as this will violate emission control levels for which the equipment was approved.
7. Compared with soybean-based and rapeseed-based feedstock, palm oil-based feedstock has a thicker consistency (i.e. higher viscosity) at lower temperatures. Consequently, fuel .lter performance may be reduced, particularly during cold weather conditions.
8. The KUBOTA Warranty, as speci.ed in the Owner’s Warranty Information Guide, only covers defects in product materials and workmanship. Accordingly, any problems that may arise due to the use of poor quality fuels that fail to meet the above requirements, whether biodiesel or mineral oil based, are not covered by the KUBOTA Warranty.
Routine handling: 1. Avoid spilling BDF onto painted surfaces as this may damage the . nish. If fuel is spilled immediately wipe clean and .ush with soapy water to avoid permanent damage.
2. When using BDF, you are advised to maintain a full tank of fuel, especially overnight and during short term storage, to reduce condensation within the tank. Be sure to tighten the fuel cap after refueling to prevent moisture build up within the tank. Water in the Biodiesel mixture will damage fuel .lters and may damage engine components.
Maintenance Requirements when using BDF B0 thru B5: Follow the oil change intervals recommended by referring to the “MAINTENANCE” section. Extended oil change intervals may result in premature wear or engine damage. Maintenance Requirements when using BDF B6 thru B20: The maintenance interval for fuel related parts changes. See the table below for the new maintenance interval. Items Interval Remarks Fuel . lter Replace every 250 hrs Fuel hose Check every 100 hrs Replace if any deterioration (crack, hardening, scar or deformation) or damage occurred. Replace every 1 year Consult your local KUBOTA Dealer for this service.
Long Term Storage: 1. BDF easily deteriorates due to oxygen, water, heat and foreign substances. Do not store B6 thru B20 longer than 1 month and B5 longer than 3 months.
2. When using B6 thru B20 and storing the machine longer than 1 month, drain the fuel from the tanks and replace with light mineral oil diesel fuel. Subsequently, run the engine at least 30 minutes to remove all of the Biodiesel from the fuel lines.
3. When using B5 fuel and storing machine longer than 3 months, drain the fuel from the tanks and replace with light mineral oil diesel fuel. Subsequently, run the engine at least 30 minutes to remove all of the Biodiesel from the fuel lines.

1. The lifting capacities are based on ISO 10567 and do not exceed 75% of the static tilt load of the machine or 87% of the hydraulic lifting capacity of the machine.
2. The strokes are as follows.
1) The load point corresponds to the front bolt part of the arm. 2) The machine positions are (i) over – front (Blade up), (ii) over – front (Blade down), and (iii) over – side.
3) The operating cylinder is the boom cylinder.
3. The bucket of the excavator, the hook, the sling and other lifting accessories are taken into consideration for the loads.
Machine conditions: No bucket, all others according to the standard regulations.
3 WARNING To avoid personal injury or death: It is forbidden to lift loads greater than those values mentioned in the lifting capacity tables. The values mentioned in the table are valid only on even, hard grounds. When lifting on soft ground, the machine 'can tilt over due to the fact that the load is concentrated only on one side of the machine. The table values are calculated at the end of the arm without the bucket. In order to .nd the allowable loads for machines with bucket, the bucket weight must be subtracted from the values in the table.
3 WARNING To avoid personal injury or death: In this manual, the machine's lifting capacity is discussed, but it does not mean that it is recommended to use the machine for lifting jobs. It is speci. ed in item 3.4 of ISO 10567:1992 that the following devices must be additionally installed if a hydraulic excavator with the rated lift load of over 2,205 lbs (1,000 kg) at its minimum lifting radius or the tilting moment of over 29,504 ft-lbs (40,000 N-m) is used for lifting loads.
