REMOVAL AND INSTALLATION
REMOVAL OF RUBBER TRACK SHOES
1 - Rotate the turret by 90ë to the side of the track-shoe
to be removed and rest the back of the bucket on the
ground with the arm perpendicular to the ground.
2 - Slowly loosen the grease nipple (1) to let out the
grease and release the tension of the track-shoe (2).
The grease contained in the idler cylinder is under
pressure and could seriously injure the Operator.
For this reason the valve should never be loosened
by more than one turn.
H If the grease does not run out easily, move the
machine slowly backwards and forwards.
3 - Force the boom downwards to raise the machine.
4 - Insert three steel pipes into the track-shoe and then
reverse the track-shoe until the first pipe is above
the idler.
5 - Push the track-shoe (2) outwards and remove it.
