EPLACING THE RUBBER TRACKS
The grease contained in the hydraulic track is pressurised. For this reason, do not loosen the
greasing valve 1 by more than 1 turn; if the valve is loosened too much, it risks being expel‑
led under the effect of the pressure of the grease, putting the safety of the operator at risk.
Never loosen greaser 2.
When gravel or mud are blocked between the toothed wheel and the track links, remove it
before loosening.
Removing the rubber track
1. Stop the machine on solid, level land, lift it and support it in safe conditions, using the
outriggers.
2. Remove the screws and take of adjustment access lid 3.
3. To loosen the track, slowly unscrew valve 1 in an anti‑clockwise direction for no more
than one turn. One turn of valve 1 is sufficient to loosen the track.
4. If the grease does not start to drain, turn the track slowly.
5. Insert 3 steel pipes (4) inside the track in the space
between the rollers. Turn the driving wheel backwards
(5) in a way that the steel pipes proceed with the track
and engage on the track‑tensioning wheel. Apply force
(6) laterally to allow the track to run and lift it from the
track‑tensioning wheel.
Installing the rubber track
1. Ensure safe conditions with the machine lifted to proceed with mounting the tracks.
2. Check that the grease contained in the hydraulic cylinder has been removed.
