MAINTENANCE PROCEDURES
To reduce the track tension, proceed as follows:
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.
NOTICE
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.
