Track unit, adjusting tension
WARNING
Risk of serious injury
Recoil spring cylinder is filled with pressurised
grease. High pressure grease in the cylinder could
cause serious injury or death.
Always keep face, hands and body away from the
grease nipple and valve when adjusting the track
tension or loosening the track. Never remove the
grease fitting or nut and valve assembly to release
grease.
Tightening track tension - reducing slack
1 Fill the grease through grease nipple (B) using a
grease gun with high pressure.
2 Check the tension by moving the machine
forward and rearward.
3 Check the tension again. If not correct, adjust it
again.
Loosening track tension - increasing slack
1 Loosen the valve (A) gradually to drain the
grease, but not more than one turn.
If the grease does not drained smoothly, move
the machine forward and rearward.
NOTICE
Risk of environmental pollution!
The grease in the track adjustment cylinder is under
high pressure and large quantities of grease will be
quickly released if the valve is loosened too much.
Never loosen the valve by more than two turns
when draining the grease.
2 Close the valve (A) but do not tighten
excessively as the fitting may be damaged.
