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.

(1) Helmet

(2) Clothing .t for work

(3) Tight seams

(4) Good grip shoewear

(5) Well . tting cuffs

(6) Working gloves

(7) Straw hat

(8) Towel

(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.

Overheat warning If the water temperature has risen too high, the water temperature warning lamp lights up and the following error code (E:015) gets displayed.

With the error code displayed, take the procedure below. 1. Bring the machine to a stop on a safe place. (Get the engine unloaded.)

2. Do not yet stop the engine, but allow it to run idle unloaded for 5 minutes or so. Then stop the engine.

3. Keep yourself away enough from the machine for another 10 minutes or while the engine is emitting steam.

4. Make sure there is no risk of getting burned. Then remove the cause of overheat, referring to “TROUBLESHOOTING”. Finally get the engine restarted.

• Checkpoints after Starting the Engine After starting the engine, but before starting operation, check the following points: 1. Put the throttle lever down and let the engine idle for approx. . ve minutes. This allows the engine lubricant to warm up and penetrate every part of the engine.

2. Once the engine has warmed up, check:

• the warning lamp ”Engine oil pressure” has gone out.

• the warning lamp ”Battery charge” goes out when engine speed is increased.

• the color of the exhaust is normal and no abnormal noises or vibrations are heard or felt.

• no .uid is leaking from pipes or hoses.

• Should any following conditions occur, stop the engine immediately.

• The engine rpm’s increases or decreases suddenly.

• Sudden abnormal noises are heard.

• Exhaust is black.

• Warning lamp for engine oil lights up during operation.

IMPORTANT: • In these cases, the excavator must be checked and serviced by your local the KUBOTA dealer. • Glow Lamp With the starter key at the ”RUN” position, the engine’s preheat status is indicated. NOTE: • When the starter switch is turned to the ”RUN” position, the engine will be preheated for a given period of time and the indicator will turn on.

• The above indication appears momentarily when the engine is started, but it does not indicate trouble. (This is because the oil charge sensor output . uctuates when the engine is started.)

• The following symbol appears momentarily as the engine starts. This is not an error.

(1) Glow lamp • Battery Charge Lamp This warning lamp lights up if the charging system fails while the engine is running. When the starter switch is turned ”ON” with the engine off, the lamp lights up, and when the engine gets started, the lamp goes out.

NOTE: • If there is disconnection, failure or breakdown in the lubricating system when the key is turned to ”RUN”, the following symbol will appear.

(1) Engine oil pressure warning lamp • Checkpoints after Starting the Engine After starting the engine, but before starting operation, check two following points: 1. Put the throttle lever in "LOW" position and let the engine idle for approx. 5 minutes. This allows the engine lubricant to warm up and penetrate every part of the engine. Note: • This idling is usually called "Warm­up". 2. Once the engine has warmed up, check: • the warning lamp "Engine oil pressure" has gone out.

• the warning lamp "Battery charge" goes out when engine speed is increased.

• the colour of the exhaust is normal and no abnormal noises or vibrations are heard or felt.

• no .uid is leaking from pipes or hoses.

• Should any following conditions occur, stop the engine immediately.

• The engine rpm's increases or decreases suddenly.

• Sudden abnormal noises are heard.

• Exhaust is black.

• Alarm lamp for engine oil lights up during operation.

IMPORTANT: • In these cases, the excavator must be checked and serviced by your local KUBOTA dealer. • Precautions in case of overheat 3 CAUTION Do not open the radiator cap during and just after operation. Hot water may gush out and get you burned. Wait long enough until the radiator cools down. If by any chance cooling water gets heated up to the boiling point or over (overheated), the whistle at the reserve tank drain hose end blows. In such case, take the following steps. 1. Stop operation in a safe condition. (Disconnect the engine’s load.)

2. Do not stop the engine suddenly. Keep the engine idling under no load for about 5 minutes and turn it off.

3. Keep yourself enough away from the machine for another 10 minutes or while steam is given off.

4. Make sure there is no hazard of getting burned. Pinpoint and remove the cause of overheat, referring to “TROUBLESHOOTING”. Then get the engine restarted.

STARTING THE ENGINE UNDER COLD CONDITIONS 3 CAUTION To avoid personal injury: Make sure that the lock lever is in the lock position during warm up. Start the engine in the following manner; 1. Pull the lock levers all the way back (lock position).

2. Turn the starter switch to the "RUN" position (glow position) and keep until the indicator lamp has gone out.

3. Move the starter switch to the "START" position; to crank and start the engine.

4. Release the starter switch after the engine has started; it will automatically return to the "RUN" position.

IMPORTANT: • Let the engine warm up after start­up for approx. 10 minutes under no load conditions. If the hydraulic . uid temperature is too low, the operations will be affected. Do not operate the excavator under full load before the engine has warmed up enough.

STOPPING THE ENGINE 3 WARNING To avoid personal injury or death: Do not keep the bucket or dozer in the lifted position, as a person could accidently touch the levers and cause serious accidents. 1. After slowing the engine to idle, turn the key to "STOP".

2. Remove the key.

• Emergency Engine Stop Fuse 3 CAUTION To avoid personal injury: Do not open engine hood before stopping engine. Only when engine does not stop by key, open engine hood and pull out the fuse. The engine will stop when the cap is removed and the fuse inside is pulled out. The engine can be restarted when the fuse is pushed back into its original position.

(1) Emergency engine stop fuse (A) “OPEN” (B) “PULL OUT” NOTE:

• If the engine does not stop with the key, contact your KUBOTA dealer.

STARTING WITH AN AUXILIARY BATTERY

3 CAUTION To avoid personal injury: Battery gases can explode. Do not smoke and keep sparks and . ames away. Do not start the engine with an auxiliary battery if excavator battery is frozen. Do not connect the black jumper cable to the negative (—) terminal of the excavator battery. Observe Following Guidelines when Starting with an Auxiliary Battery 1. Bring the helping machine with the same battery voltage as near as possible to the machine. THE MACHINES MUST NOT COME IN CONTACT WITH EACH OTHER.

2. Bring the levers and pedal of both machines in the neutral position.

3. Wear eye protection and rubber gloves.

4. Remove the battery caps from both batteries. (If present)

5. Connect the terminal of the red jumper cable with the plus (+) terminal of the low battery and connect the other end of the cable to the plus (+) terminal of the auxiliary battery.

6. Connect the black negative cable to the minus (—) terminal of the auxiliary battery.

7. Connect the other end of the black cable (coming from the auxiliary battery) to the machine frame as far away as possible from the low battery.

8. Start the engine of the helping machine and let it run for a while. Start the machine with the low battery.

9. Disconnect the jumper cables in the reverse sequence.

(1) Low battery

(2) Auxiliary battery

(3) Jumper cables

IMPORTANT: • This excavator has a negative (—) earthed 12 Volt starting system.

• Only use the same voltage when using an auxiliary battery.

• Using a higher voltage will cause serious damage to the electrical system. When using an auxiliary battery, only the compatible (same) voltage is permissible.

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.
