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 degree of wear of pins and bushings varies depending on the work conditions and on the
characteristics of the ground.
It is therefore necessary to check the track tension frequently, in order to ensure that it is always
correct.
q When working on rocky or very irregular surfaces, increase the track tension in order to prevent
stones or debris to get stuck between the tracks and the sprocket; on the other hand, reduce the track
tension when working on soft or muddy ground, since the soil penetrates between rollers and tracks
and tends to increase the tension.
