ADJUSTMENT
DANGER
•
The grease contained in the hydraulic cylinder is under
pressure. For this reason, do not loosen the greasing valve
(1) giving it more than one turn; if the valve is loosened ex-
cessively, it may be pushed out due to the grease pressure
and this is very dangerous for the operator.
Do not loosen any other component in addition to the valve
(1).
•
If you notice excessive resistance while injecting grease,
slowly move the machine forward and backward for a short
distance.
To increase the tension
1 - Loosen the screws and remove the cover to reach the adjust-
ment point.
Use a 13 mm spanner.
If the injection of grease is difficult to carry out, slowly move
the track for a short distance.
2 - Carefully clean the greasing valve (1) and inject grease
through the greaser (2) until obtaining the desired tension.
To reduce the tension
1 - Gradually loosen the greasing valve (1) to let the grease out;
do not give the valve more than one turn.
Use a 27 mm hexagon spanner.
2 - If the grease does not flow out freely, move the machine slowly
forward and backward for a short distance.
3 - Tighten the valve and remove any trace of grease.
4 - Move the machine forward and backward and, after stopping
it, check the track tension again.
IMPORTANT
☞
•
The wear of pins and bushings varies according to the
work conditions and the characteristics of the ground on
which the machine operates.
Therefore, it is necessary to check the track tension fre-
quently.
•
When working on rocky or extremely uneven ground, in-
crease the track tension in order to prevent the introduc-
tion of stones or rubble between the tracks and the
sprocket; when working on soft or muddy ground, de-
crease the track tension, since the soil penetrates between
rollers, sprocket and tracks and tends to increase it.
