Page 217 OPERATION MACHINE OPERATIONS AND CONTROLS When the machine is operated on sites with no fuel container and pump, the machine may be refuelled from fuel barrels. The refuelling pump is located in the right hand tool case of the machine. Remove the refuel hose which is stored in tool case (3) from the machine.
Page 218 MACHINE OPERATIONS AND CONTROLS OPERATION Refuelling will continue automatically until the tank has reached capacity (float switch (6) will reach its limit and the pump will stop). It is important to ensure the machine is parked on level ground and monitor refuelling to avoid fuel overfill or spill- age.
Page 219 OPERATION MACHINE OPERATIONS AND CONTROLS METHOD FOR CHECKING WATER SEPARATOR, DRAINING WATER AND SEDI- MENT Open the pump room door on the right side of the ma- chine. Check for water and sediment. It is possible to judge the water level and amount of sedi- ment by looking through transparent cup (2).
Page 220 MACHINE OPERATIONS AND CONTROLS OPERATION Loosen drain valve (4) and drain water and sediments from transparent cup (2), and also drain all the fuel from fuel prefilter cartridge (1). Check that nothing more comes out from drain hose (3), then remove drain valve (4). Apply a suitable amount of grease to O-ring (7).
Page 221 OPERATION MACHINE OPERATIONS AND CONTROLS Open the door on the right side of the machine and check sight gauge (G). When the oil level is between the lines H and L, it is appro- priate. If the oil level is below level L, the hydraulic oil is insuffi- cient.

Page 272 MACHINE OPERATIONS AND CONTROLS OPERATION PROHIBITION OF OPERATIONS USING TRAVEL FORCE Do not use the travel force to perform excavation by digging the bucket into the ground. This damages the machine or work equipment. PROHIBITION OF OPERATIONS USING HYDRAULIC CYLINDERS TO STROKE If the work equipment is used with the cylinder rod operated to its stroke end, and given impact by some external force, the hy- draulic cylinders may be damaged, causing personal injury.
Page 273 OPERATION MACHINE OPERATIONS AND CONTROLS PROHIBITION OF OPERATIONS USING MACHINE DROPPING FORCE Do not use the dropping force of the machine for digging. PROHIBITION OF DIGGING OPERATION AT AN ANGLE WITHOUT ENGAGING TEETH If the machine swings and digs simultaneously while the bucket blade does not bite into hard rocks at a position higher than the machine, the teeth slide down on the rock surfaces.
Page 274 MACHINE OPERATIONS AND CONTROLS OPERATION PROHIBITION OF OPERATIONS WHEN MACHINE IS NOT STABLE If the machine is operated while its undercarriage is unstable, torsional loads occur in the frames and can shorten the service life of the machine. In this case, prepare an embankment, etc. in front of the track to stabilize the machine.
Page 275: Precautions For Operation
OPERATION MACHINE OPERATIONS AND CONTROLS PROHIBITION OF HIGH-SPEED TRAVEL OPERATIONS ON ROUGH GROUND If the machine travels on rough ground (rock-bed, etc.) at high speed, large push-up loads are applied to the chassis, thus the service life of the chassis is shortened.

Check the nitrogen gas charge pressure as follows. Place the machine on a flat ground. Hold the work equipment in the maximum reach posture (arm fully OUT, bucket fully DUMP) at height (A) 1.5 m from the ground.
Page 419 If the work equipment does not go down or stops in midway, the charged pressure of the gas in the accumulator for the hy- draulic circuit has probably dropped. Ask your Komatsu distrib- utor for inspection. This completes the inspection. After completion of the inspection, set the lock lever to LOCK position and turn the starting switch to OFF position.
Page 420: Method For Checking Alternator
If the engine is started frequently, have this inspection performed every 1000 hours. METHOD FOR CHECKING AND ADJUSTING ENGINE VALVE CLEARANCE Special tools are necessary for inspection and maintenance. Ask your Komatsu distributor to perform this work. METHOD FOR REPLACING KCCV FILTER ELEMENT WARNING After the engine has been operated, all of the parts are still very hot.
Page 421 MAINTENANCE MAINTENANCE PROCEDURE NOTICE • If the engine is operated without the filter element, the turbocharger and aftercooler become dirty and their performance will lower and that can cause engine problems such as overrun caused by suction of oil. Therefore, do not start the engine without the filter element. •...
Page 422 MAINTENANCE PROCEDURE MAINTENANCE There may be oil accumulated or sticking in the case and element. Take care not to spill the oil when replacing the element. REMARK When the ambient temperature is low, water or emulsified matter may stick to the inside of KCCV because of con- densation of water vapor in the blowby gas.
Page 423: Method For Replacing Def Filter
Komatsu recommends using Komatsu genuine parts for replacement parts. • If the machine is operated without DEF filter attached, or with the filter other than Komatsu genuine parts, foreign materials may enter into DEF pump and DEF injector which will cause failure of the machine.
Page 424 MAINTENANCE PROCEDURE MAINTENANCE After the engine is stopped, DEF system devices automatically purge DEF in DEF injector and DEF pump and return it to DEF tank to prevent malfunction of the devices caused by freezing of DEF or deposition of urea. After the engine is stopped, the devices are operated for a few minutes.
Page 425: Every 4000 Hours Maintenance
MAINTENANCE MAINTENANCE PROCEDURE Check that filter removal tool (3) is fully inserted to the end. Insert the filter to the end where you cannot thrust it in any further. Turn filter removal tool (3) in reverse, and remove filter (6). Filter (6) is removed and you can take it out together with filter removal tool (3).
Page 426: Replace Defined Life Parts
METHOD FOR CHECKING WATER PUMP Check around the water pump for oil leakage and water leak- age. If any problem is found, contact your Komatsu distributor to have the parts disassembled, repaired, or replaced. METHOD FOR CHECKING VIBRATION DAMPER Ask your Komatsu distributor for inspection of the vibration damper.
Page 427: Method For Checking Starting Motor
• Do not hit or roll it, or subject it to any impact. • When disposing of it, the gas must be released. Ask your Komatsu distributor to have this work per- formed. NOTICE If the nitrogen gas charge pressure in the accumulator is low and operations are continued, it becomes impossible to release the remaining pressure inside the hydraulic circuit if a failure occurs on the ma- chine.
Page 428: Method For Checking For Looseness Of Engine High-Pressure Piping Clamp, Hard- Ening Of Rubber
MAINTENANCE PROCEDURE MAINTENANCE If any abnormality is found, ask your Komatsu distributor to have the parts disassembled, repaired, or re- placed. METHOD FOR CHECKING FOR LOOSENESS OF ENGINE HIGH-PRESSURE PIP- ING CLAMP, HARDENING OF RUBBER Check visually and touch by hand to check that there is no hardening of the rubber and no loose bolts of the mounting clamps (2 places) for the high-pressure piping between the supply pump and the common rail.
Page 429: Every 4500 Hours Maintenance
MAINTENANCE MAINTENANCE PROCEDURE If there are any problems, the related parts must be replaced. Ask your Komatsu distributor for replacement. EVERY 4500 HOURS MAINTENANCE Maintenance for every 100, 250 and 500 hours should be performed at the same time. METHOD FOR CLEANING KDPF Contact your Komatsu distributor for cleaning of the KDPF.
Page 430: Every 8000 Hours Maintenance
Maintenance for every 100, 250, 500, 1000 and 4500 hours service should be performed at the same time. METHOD FOR REPLACING DEF HOSE Ask your Komatsu distributor for replacement of the DEF hose.
