If the track tension is not the standard value, adjust in the following
manner.
Adjustment
Grease inside the adjusting mechanism is under high pressure.
Grease coming from plug a under pressure can penetrate the body
causing injury or death. For this reason, do not loosen any part
other than the plug a more than one turn. Do not bring your face in
front of the plug (1). If the track tension is not relieved by this proce-
dure, please contact your Komatsu distributor.
When increasing tension
Prepare a grease gun.
1. Pump in grease through grease fitting b with a grease gun.
2. To check that the correct tension has been achieved, move the ma-
chine backwards and forwards.
3. Check the track tension again, and if the tension is not correct, adjust
it again.
4. Continue to pump in grease until S becomes 0 mm. If the tension is
still loose, the pin and bushing are excessively worn. so they must be
either turned or replaced. Please contact your Komatsu distributor
