Decreasing tension
1. Remove both bolts (2) and cover (1).
2. Loosen plug (4) little by little to discharge
grease.
3. Do not loosen plug (4) more than 1 turn.
4. If grease is not discharged well, move the
machine forward and backward a little.
5. Tighten plug (4).
6. Move the machine forward and backward
to check that the track tension is proper.
7. Check the track tension again. If it is not
proper, adjust it again.
Precautions
•
Do not loosen plug (4) more than 1 turn. If it is loos-
ened more, it may jump out because of the internal
high-pressure grease. At this time, do not loosen
any part other than plug (4). Do not direct your face
toward plug (4) in its installing direction.
If the track tension cannot be decreased by the
above procedure, ask your Komatsu distributor for
repair.
•
When removing cover (1), take care that dirt and
sand will not enter.
•
Take care not to damage the safety label stuck to the
reverse side of cover (1).
