TRACK LOOSENING / TIGHTENING PROCEDURES.
The grease contained in the hydraulic track is pressurized. Never loosen grease valve (74)
for more than one turn. If the valve is loosened too much you risk expelling grease under
pressure and possible serious injury to the machine operator. Also never loosen grease
nipple (73).
Remove gravel or mud from between the sprocket and the track.
Remove the screws and take off cover (68) to access the adjustment system.
To loosen the track turn valve (74) counter-clockwise no more than one turn. One turn of
valve (74) is sufficient for loosening the track.
If grease does not start to drain out then slowly rotate the track.

Tighten the valve (74) by turning clockwise till tight. Clean
all traces of extruded grease.
To tighten the track connect a grease gun to grease nipple
(73) and pump grease until the track tightens so that there
is 10-15 mm of sag. Then stop
FRONT IDLER LOCKING
It is not normal for the track to remain tight after turning
valve 1 counter-clockwise or for it to remain loose after
introducing grease into grease nipple 2. Never try to
remove the tracks or disassemble the track-stretching
cylinder since pressure of the grease inside the track is
extremely dangerous.
