When this maintenance is carried out, it is necessary to open (tilt) the floor.
Before starting the operation to open the floor, read the precautions in "CAUTIONS FOR OPENING (TILTING) FLOOR (PAGE
2-36)" in the safety and maintenance sections thoroughly, and refer to the explanation for each part in "METHOD OF OPENING
(TILTING) FLOOR (PAGE 3-29)" when carrying out the operation. Or ask your Komatsu distributor to carry out the
maintenance.
Immediately after the engine is stopped, the parts and oil are at a high temperature, and will cause burns. Wait for the
temperature to go down before starting the operation.
When removing the oil filler cap, oil may spurt out, so turn it slowly to release the internal pressure before removing it.
