7.11.4 CHANGING THE RUBBER TRACKS
The grease contained in the hydraulic track is pressurised. For this reason, do not loosen
grease nipple 1 more than 1 turn; if the nipple is loosened excessively, it may be expelled due
to the pressure of the grease, putting the safety of the operator at risk.
Never loosen grease nipple 2.
When gravel or mud is stuck between the sprocket and the track links, remove it before loo‑
sening.
Removing the rubber track
1. Stop the machine on solid and level ground, lift it and support it in safe conditions, using
the stabilisers.
2. Remove the screws and the adjusting mechanism access cover 3.
3. To loosen the track, slowly unscrew valve 1 anticlockwise giving no more than one turn.
One turn of valve 1 is sufficient to loosen the track.
4. If the grease does not start to come out, turn the track slowly.
5. Insert 3 steel pipes (4) inside the track in the space
between the rollers. Turn the sprocket backwards (5) so
that the steel pipes move with the track and engage the
idler roller. Force laterally (6) to make the track slide and
lift it from the idler roller.
Fitting the rubber track
1. Before fitting the tracks, make sure that the machine is lifted and in safe conditions.
2. Check that the grease in the hydraulic cylinder has been removed.
