25. Procedures for Maintenance

3-29

Removing the rubber crawler

1) Raise the machine with the implement and the safety

blocks.

To do this, slowly operate the control lever.

2) Loosen the nipple valve (1) little by little to gradually dis-

charge the grease.

3) Never loosen the nipple valve (1) more than one turn.

4) Insert the steel pipes into the rubber crawler and turn

the sprocket in the reverse direction. When the rubber

crawler is separated from the idler by the steel pipes,

slide the rubber crawler off.

• It is very dangerous to discharge the grease by

any procedure other than that described below.

• If the tension of the rubber crawler cannot be

properly adjusted, ask your dealer to repair or re-

place the rubber crawler.

• When removing the rubber crawler, make sure

that all of the grease has been completely dis-

charged before turning the sprocket.
