MAINTENANCE

EVERY 2000 HOURS SERVICE

Maintenance for every 100, 250, 500 and 1000 hours should
be carried out at the same time.
CLEAN HYDRAULIC TANK STRAINER
The parts and oil are at high temperature after the engine
●
is stopped, and may cause serious burns. Wait for the
temperature to go down before cleaning the hydraulic
tank strainer.
When the oil filler cap is removed, oil may spurt out, turn
●
the cap slowly to release the internal pressure, then
remove it carefully.
1. Loosen 6 bolts, then remove cover (1).
2. When doing this, the cover may fly out under the force of
spring (2), so push the cover down when removing the bolts.
3. Pull up the top of rod (3), and remove spring (2) and strainer
(4).
4. Remove the dirt stuck to strainer (4), then wash it in clean die-
sel oil or flushing oil.
5. If strainer (4) is damaged, replace it with a new one.
6. Refit strainer (4) by inserting it into the tank projecting part (5).
7. Assemble it so that the protruding part at the bottom of cover
(1) holds spring (2), then tighten the cover with the bolts.
CLEAN, CHECK TURBOCHARGER
Contact your Komatsu distributor for cleaning or inspection.
CHECK ALTERNATOR, STARTING MOTOR
The brush may be worn, or the bearing may have run out of
grease, so contact your Komatsu distributor for inspection or
repair. If the engine is started frequently, carry out inspection
every 1000 hours.
CHANGE ANTIFREEZE
Follow the procedure of "CLEAN INSIDE OF COOLING
SYSTEM (253)" for draining and refilling the cooling sys-
tem.
