2.8.21 PRECAUTIONS TO BE TAKEN WHEN
USING HIGH-PRESSURE GREASE
TO ADJUST THE TRACK TENSION
q
The grease contained in the track tension adjustment device is
pressurized. If the adjustment is not carried out according to the
instructions given in the maintenance section, the grease valve
(1) may be ejected due to the high pressure and this may be
dangerous for the operator.
q
When loosening the valve (1) to reduce the track tension, do not
give it more than one turn.

Keep your face, hands and other body parts away from the
valve (1).
2.8.22 DO NOT REMOVE THE SHOCK ABSORBING SPRING FROM THE
SHOCK ABSORBER UNIT

The shock absorber unit is provided with a shock absorbing spring with high preload, in order to absorb the im-
pacts of the front idler roller.
Do not attempt to remove the spring, since this may lead to serious accidents and even death.
For any operation on the shock absorber unit, contact your Komatsu Distributor.
