INCREASING THE TRACK TENSION
IMPORTANT
q
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 ten-
sion.
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.
REDUCING THE TRACK TENSION
DANGER
q
It is extremely dangerous to let the grease out following any procedure different from those illustrated
below.
q
If the track tension cannot be reduced with this operation, contact your Komatsu Distributor, who will
provide for the necessary repairs.
1. Gradually loosen the grease valve (1) to let the grease out;
do not give the valve more than one turn.
2. If the grease does not come out smoothly, move the machine
slowly forward and backward covering a short distance.
3. Tighten the valve and remove any trace of grease.
4. Move the machine forward and backward, then stop it and
make sure that the track tension is correct.
IMPORTANT
q
The rubber tracks wear out to different degrees, depending
on the work conditions and on the characteristics of the
surface on which the machine is working. It is therefore
necessary to check the track tension frequently, in order to
ensure that it is always correct.
q
When working on soft or muddy ground, reduce the track
tension to extend the service life of the components.
q
After the installation of new tracks, it is advisable to carry
out a first check after 10 hours of operation.
