If the track shoe tension is not within the standard value, adjust as follows.

1. When the tension is too high:

Loosen plug (1) gradually, and release the grease. A There is danger that the plug may fly out under the high internal pressure of the grease, so never loosen plug (1) more than 1 turn. * If the grease does not come out easily, move the machine backwards or forwards slowly.

2. If track is too loose: Pump in grease through grease fitting (2). If the grease cannot be pumped in easily, move the machine backwards and forwards slowly.;

Warning: This procedure requires trained personnel with PPE!

Work equipment lowered to the ground and engine stopped?
