MAINTENANCE
Adjustment
The grease contained in the hydraulic cylinder is
pressurized. For this reason, do not give the grease valve
(1) more than one turn when loosening it; in fact, if the
valve is loosened excessively it may be pushed out due to
the grease pressure and this is very dangerous for the
operator.
Do not loose any component apart from the valve (1). If the
track tension does not decrease after this operation,
contact your Komatsu distributor.
If the resistance met when injecting the grease is
excessive, move the machine forward and backward
covering a short distance.
To increase the track tension, proceed as follows:
NOTICE
The standard adjustment value is low, therefore take care
to avoid increasing the rubber track tension excessively.
1. Carefully clean the grease valve (1) and inject grease
through the grease nipple (2) until reaching the desired
tension.
2. If the rubber track cannot be tensioned enough by injecting
grease, it is necessary to change the track or the track
tensioner gaskets. For any repair or replacement, contact
your Komatsu distributor.
