MAINTENANCE
SERVICE PROCEDURE
EVERY 1000 HOURS SERVICE
Maintenance for every 50, 100, 250 and 500 hours service should be carried out at the same time.
REPLACE FUEL FILTER CARTRIDGE
WARNING
Immediately after the engine is stopped, all parts are at high temperature, so do not replace the filter immediately.
Wait for the engine to cool down before starting the operation.
The inside of fuel piping system of the engine is under high-pressure when the engine is running. When replacing the filter,
wait for at least 30 seconds after the engine stops to let the internal pressure go down before replacing the filter.
Do not bring any fire or spark close.
Be careful when opening the air bleed plug at the fuel filter head and the air bleeder of the supply pump. The system is still
under pressure and fuel may spurt out.
NOTICE
Genuine Komatsu fuel filter cartridges use a special filter that has highly efficient filtering ability. When replacing the filter
cartridge, always use a genuine Komatsu part.
The common rail fuel injection system used on this machine consists of more precise parts than the conventional injection
pump and nozzle.
If any part other than a genuine Komatsu filter cartridge is used, dust or dirt may get in and cause problems with the injection
system. Always avoid using substitute parts.
When carrying out inspection or maintenance of the fuel system, pay more attention than normal to the entry of dirt. If dirt is
stuck to any part, use fuel to wash it off completely.
Prepare a filter wrench
1. Close supply valve (1) of the fuel tank.
2. Set the container to catch the fuel under the filter cartridge.
3.
Using a filter wrench, turn filter cartridge (2) counterclockwise
to remove it.
4. Clean the filter holder.
