SAFE OPERATION

SAFE OPERATION

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 "Operator's Manual Storage" in "CHECKS BEFORE START" section.) 1. BEFORE OPERATION 1. Make yourself acquainted with the excavator and be aware of its limits. Read the operating instructions 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 definition to FOPS (Falling Object Protective Structure). Always use the seat belt when the machine is equipped with a ROPS/OPG (Top Guard Level I). Do not modify structural members of ROPS 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 ROPS is loosened or removed for any reason, make sure all parts are reinstalled correctly. Tighten mounting bolts to proper torque. 4. The seat belt must be inspected regularly and replaced if damaged.

5. Always sit in the operator's seat when starting engine or operating levers or controls.

6. Study control lever pattern A and pattern B. Then choose the one which is most familiar. Familiarize yourself with the pattern selected by operation slowly at low engine speed.

A Engage the lever lock to prevent accidental pattern change.

7. Do not operate the excavator while under the influence of alcohol, medication, controlled substances or while fatigued.

8. Check the surroundings carefully before using the excavator or when attachments are being attached.

A Pay attention to the overhead clearance with electric wires.

A 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 completely understood. 10.Do not wear baggy, torn or oversized 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 (7) Straw hat

(2) Clothing fit for work (8) Towel

(3) Tight seams (9) Baggy trousers

(4) Good grip footwear (10) Loose cuffs of the shirt

(5) Well fitting cuffs (11) Baggy shirt

(6) Working gloves (12) Rubber sandals

11.Do not allow passengers to ride on any part of the excavator at anytime. The operator must remain in the excavator seat during operation. 12.Check mechanical parts for correct adjustments and wear. 13.Keep your excavator clean. Heavy soiling, grease, dust and grass can cause fires, accidents or injuries. 14.Use only KUBOTA authorized attachments. 15.Before starting the excavator, be absolutely sure that the excavator has been filled with fuel, lubricated, greased and undergone all necessary maintenance. 16.Do not modify the excavator, otherwise it could lead to unforeseen safety problems. 17.Do not hammer anything that is above the operator's seat level. Objects may fall into the operator station of mini-excavator from front. 18.Make sure attachments, particularly those utilizing quick attach systems, are securely mounted. SAFE OPERATION

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 levers 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 lock levers are in position "Lock" and all control levers and pedals are in their neutral positions and the seat belt is fastened correctly. 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. Make sure that the dozer blade is in front of you. (The dozer blade must be raised.) If the levers are activated with the dozer blade at the rear, the tracks will move in the opposite direction of the drive levers.

5. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.

6. Keep all safety equipment and covers in place. Replace damaged or missing safety devices.

7. Precautions against tipping over. Keep away from steep slopes and embankments. Do not swing the bucket downhill. Lower the dozer blade during digging. Keep the bucket as low as possible while driving uphill. Turn slowly on slopes (at reduced speed). Do not place the excavator near the edges of trenches and banks, as the earth can give away due to the weight of the excavator. ALLOWABLE CLIMBING ANGLE : 36 % (20 deg.) ALLOWABLE ANGLE IN CASE OF CROSSING SIDEWAY : 27 % (15 deg.)

8. Watch out at all times for the area to which the excavator is being moved. Pay attention to any hindrances.

9. Keep enough distance from trench and bank edges.

C Safety for children Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted 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 not a 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 firm, flat 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 and lock the cab door (if equipped), before you leave.

3. AFTER OPERATION Before leaving the machine, A Park the excavator on a firm, flat and level surface. A Lower the attachments and the dozer blade to the

ground. A Stop the engine. A Release pressure trapped in the hydraulic system. A Lock all control levers. A Remove the key.

(1) Pilot control lock lever (A) "Unlock" (B) "Lock"

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 the machine. (for details see "TRANSPORTING THE EXCAVATOR ON A VEHICLE")

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. Lower the attachment on the loading bed and release the pressure from the hydraulic system. After loading the excavator on the truck, block the tracks with blocks and cable down the excavator.

5. Avoid abrupt braking of the vehicle with the excavator loaded. Sudden braking cause the excavator to move and may cause a serious accident.

6. If the excavator is to tow another machine, make sure the load is smaller than the strength of the hook, tow chain or cable.

7. Do not use hooks on the roof of canopy or CAB for lifting the excavator.

Max. drawbar pull at coupling hook 70450 N (15838 lbf, 7184 kgf) Max. vertical load at coupling hook 7210 N (1621 lbf, 735 kgf)

5. MAINTENANCE Before doing maintenance work on the excavator, place the machine on even solid ground, lower the attachments to the ground, stop the engine and remove the key. When dismantling hydraulic parts, make sure that the hydraulic oil has cooled down sufficiently to avoid burns. Start maintenance work carefully, e.g. loosen plug 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 sufficiently.

2. Turn off the engine at all times when filling with fuel. Avoid spilling and over-filling of fuel.

SAFE OPERATION

3. Smoking is prohibited while refueling or handling the battery. Keep sparks and fire away from the fuel tank and battery. Flammable gases escape from the battery, especially during charging.

4. Do not use or charge the refillable type battery if the fluid level is below the LOWER (lower limit level) mark. Otherwise, the battery component parts may be prematurely deteriorated, which may shorten the battery's service life or cause an explosion. Check the fluid level regularly and add distilled water as required so that the fluid level is between the UPPER and LOWER levels.

5. Read and follow the directions "STARTING WITH AN AUXILIARY BATTERY" in "OPERATION OF THE ENGINE", when starting with an auxiliary battery.

6. Keep a first-aid box and a fire extinguisher at hand at all times.

7. Do not open the radiator cap before the radiator has cooled down sufficiently First loosen the cap to the first stop and allow the system enough time to release the remaining pressure. Then loosen the cap completely.

8. To avoid short-circuiting the battery, always remove the ground cable first and attach the positive cable first.

9. Leaking hydraulic fluid has enough pressure to penetrate the skin and cause serious injuries. Leakages from pin holes can be totally invisible. Do not use hands for checking for leaks. 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 fluid, contact a doctor immediately. This fluid can cause gangrene or serious allergic reactions.

10.To avoid environmental damage from acid and heavy metals, do not throw the battery away. 11.Observe all laws and regulations concerning the disposal of used oil, coolants, solvents, hydraulic fluids, battery acids and batteries. 12.To avoid fire, do not heat the hydraulic components (tanks, pipes, hoses, cylinders) before they have been 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 dismantle the spring of the track tensioner. If dismantling is necessary, contact your KUBOTA dealer where the machine was purchased, or competent service shop. The assembly must be done according to the work shop manual of KUBOTA (W.S.M.) for the product involved. 16.When lifting the machine itself with an attachment, place a safety block or safety post to prevent the machine from turning over. Keep the lock lever for attachment control in the "LOCK" position.

17.KUBOTA uses no parts which are lined with asbestos. Do not use these kind of parts even if they are available and can be installed. 18.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 fire prevention guidelines will help to keep your equipment up and running efficiently and keep the risk of fire to a minimum. A Blow off all accumulated debris near hot engine exhaust components such as turbocharger and exhaust manifold as well as exhaust pipes and muffler more frequently when working in severe conditions. A Clean out all accumulated flammable 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. A Inspect all fuel lines and hydraulic hoses for wear or for deterioration. Replace them immediately if they begin to leak. A 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. A Inspect the exhaust system daily for any signs of leakage. Check for broken pipes and muffler 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. A Always keep a multipurpose fire extinguisher on or near the machine. Be familiar with the operation of the fire extinguisher. SAFE OPERATION
