Check Electrical Intake Air Heater - Komatsu PC130-7 Operation & Maintenance Manual

MAINTENANCE
Loosening Track Tension
It is extremely dangerous to release the grease by any method except the procedure given below.
If the track tension is not relieved by this procedure, please contact your Komatsu distributor for repairs.
1. Loosen plug (1) gradually to release the grease.
2. When loosening plug (1), turn it a maximum of one turn.
3. If the grease does not come out smoothly, move the
machine forwards and backwards a short distance.
4. Tighten plug (1).
5. To check if the tension is correct, run the engine at low
idling, move the machine slowly forward (by an amount
equal to the length of track on ground), then stop the
machine.
6. Check the track tension again, and if the tension is not cor-
rect, adjust it again.
