ADJUSTING
*
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 one 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).
+r If the grease cannot be pumped in easily, move
the machine backwards and forwards slowly.
