MAINTENANCE 

7-55 

 

Drain Hydraulic Oil Tank Sump 
--- every 250 hours 

 

IMPORTANT:  Never run the engine without oil in hy-

draulic oil tank. 

 

1.  Park the machine on a level surface with the upper-

structure rotated 90

°

 for easier access. 

2.  Lower the bucket to the ground. 

3.  Turn the auto-idle switch off. 

IMPORTANT:  The turbocharger may be damaged if the 

engine is not properly shut down. 

 

4.  Run the engine at slow idle speed without load for 

five minutes. 

5.  Stop the engine. Remove the key from the key 

switch.  

6.  Pull the pilot control shut-off lever to the LOCK posi-

tion. 

  WARNING: Keep body and face away from cap 

(1). Turn cap (1) slowly and remove the cap only 
after releasing the internal pressure completely. 

 

7.  Insert the wrench as shown and turn the wrench 

clockwise and hold the wrench. 

8.  Turn cap (1) counterclockwise about 30

°

, at which 

point stop cap (1) to release the air. 

9.  Turn cap (1) further and remove cap (1). 

10.  Align the projected part of cap (1) with the projected 

part of the case and install cap (1). 

  WARNING: Do not loosen the drain cock until oil 

is cool. Hydraulic oil may be hot just after opera-
tion, potentially causing serious injury. 

 

11.  After oil is cool, remove drain plug (3) and open drain 

cock (2) to drain water and sediment. 

12.  After draining water and sediment, tighten drain cock 

(2) securely and install drain plug (3).
