KOMATSU GENUINE REPLACEMENT PARTS
Komatsu recommends using Komatsu genuine parts specified in Parts Book as replacement parts.
KOMATSU GENUINE LUBRICANTS
For lubrication of the machine, Komatsu recommends using Komatsu genuine lubricants. Moreover use oil of
the specified viscosity according to the ambient temperature.
ALWAYS USE CLEAN WASHER FLUID
Use automobile window washer fluid, and be careful not to let any dirt get into it.
FRESH AND CLEAN LUBRICANTS
Use clean oil and grease. Also, keep the containers of the oil and grease clean. Keep foreign materials away
from oil and grease.
CHECK DRAINED OIL AND USED FILTER
At the replacement of the filters when oil is changed, check the old oil and filters for metal particles and foreign
materials. If large quantity of metal particles or foreign materials are found, always report to the person in
charge, and perform suitable action.
PRECAUTIONS FOR REFILLING OIL OR FUEL
If your machine is equipped with a strainer, do not remove it while filling oil or fuel.
PRECAUTIONS FOR WELDING
• When conducting weld repair, turn the starting switch to OFF position and, after confirming that the system
operating lamp is turned off, set the battery disconnect switch key to OFF position and pull it out.
• Do not apply a voltage higher than 200 V continuously.
• Connect grounding cable within 1 m {3 ft 3 in} of the area to be welded. If grounding cable is connected
near instruments, connectors, etc., the instruments may malfunction.
• Prevent seals, bearings or bushings from entering the space between the weld zone and grounding point.
Seals and the like can cause damage to the nearby parts by catching fire from sparks.
• Do not use the area around the work equipment pins or the hydraulic cylinders as the grounding point.
Sparks generated there can damage the plated portion.
DO NOT DROP THINGS INSIDE MACHINE
• When opening the inspection windows or the oil filler port of the tank to perform inspection, be careful not to
drop nuts, bolts, or tools inside the machine.
If such things are dropped inside the machine, it may cause damage and/or malfunction of the machine,
and will lead to failure. If anything drops, be sure to take it out.
• Do not put unnecessary things in your pockets. Carry only things which are necessary for inspection.
DUSTY JOBSITES
When working at dusty jobsites, observe the following.
• Inspect the dust indicator frequently to see if the air cleaner is dirty or clogged.
• Clean the radiator core frequently to avoid clogging.
• Clean and replace the fuel filter frequently.
• Clean electrical components, especially the starting motor and alternator, to avoid accumulation of dust.
