25. Procedures for Maintenance
3-56
Also perform the maintenance every 50, 100, 250 and 500 service hours.
25-10-1. Replacing the hydraulic oil and cleaning the suction filter
Things to prepare
• Container for waste oil : Capacity of 4.49 Gals. (17 L) or more
• New hydraulic oil : 4.36 Gals. (16.5 L) [When all oil is
drained from all of the hydraulic equipment, pipes and
hoses, the required new oil amount is 6.87 Gals. (26 L)].
• O-ring
1) Swing the upper structure so that the drain plug (P) on
the bottom of the hydraulic oil tank is positioned in the
middle of the right and left crawlers.
2) Retract the bucket and arm cylinders to their stroke ends,
lower the boom and put the bucket teeth on the ground.
3) Put the blade on the ground and stop the engine.
4) Remove the hydraulic oil tank cover.
5) Open the engine hood (2).
6) Remove the side cover L (3).
7) Place the container for waste oil under the drain plug (P).
8) Remove the drain plug (P) and drain the waste oil.
When removing the drain plug (P), take care that the oil
does not splash on you.
25-10. Maintenance every 1000 service hours
• The hydraulic oil and the tank are hot and under
pressure at operating temperature. Never replace
the oil immediately after operation is stopped.
Wait until the tank has cooled enough to permit
you to touch its surface with your bare hand.
• When removing the oil supply port cap, slowly
loosen it to relieve the internal pressure, then re-
move the cap carefully.
• If the cover of the tank is removed too quickly,
the cover may pop out due to the spring force ap-
plied to the filter. Also, the hydraulic oil may
spout out if the pressure inside the tank has not
been gradually relieved.
Slowly loosen the four bolts diagonally to re-
move the cover.
