Adjusting Track Shoe Tension

If the track shoe tension is not normal, adjust as follows.
1. Remove cover .
2. If tension is too high:
Loosen plug (1) and release some of the grease.
There is danger that the plug may fly out under the high internal pressure of the grease, so never loosen the plug more than 1 turn.
3. If tension is too low:
Pump in grease through grease fitting (2).
– If the track tension is poor, move the machine backwards or forwards slowly.
– After completion of the adjustment, repeat the above procedure to check the tension again.
