MAINTENANCE BASICS

KEEP THE MACHINE CLEAN:

Always keep the machine clean. Keep grease nipples, ventilation

openings and oil level indicators particularly clean. Avoid any

contamination of the operating agents etc. with foreign particles.

This helps to avoid most faults.

Draining hot oil, hot coolant and the removal of filters for these

immediately after the engine has been switched off is dangerous.

For this reason, wait until the engine has cooled down to 60°C.

But: Do not drain oil in a cold state.

After changing oil or filter, check oil and filter for metal particles

and foreign bodies. If larger quantities of metal particles or foreign

bodies are found, contact your local Komatsu dealer.

Always top up fuel or oil in a sufficiently ventilated place. If the

machine is provided with a fuel sieve in the tank opening, do not

remove this fuel sieve before you start refuelling. Relock the tank

opening after refuelling.

You may slip on spilled fuel or oil or spilled fluid may ignite. For

this reason, remove immediately any spilled fluid.

Never use fuel for rinsing or cleaning parts. Make sure that oil or

fuel does not contaminate the ground or water. Dispose of these

fluids appropriately.

Checking oil level and oil-changes should only be carried out at

dust-free locations to avoid any foreign bodies getting into the oil.

Attach a warning sign to the start switch when performing

maintenance operations so that no one can accidently start the

engine. The warning sign is supplied with the tools.
