ADJUSTING THE TENSION
This operation is to be carried out after the tension
has been checked.
TO INCREASE TENSION
1. With the track raised, clean the grease fitting
adaptor and the grease fitting.
2. Connect the grease pump. Inject grease to
obtain the right amount of track sag. See Track
tension value.
3. Remove the grease pump and clean the grease
fitting.
4. Repeat Steps 1 to 3 for the other track.

TO REDUCE TENSION
1. With the track in raised position, loosen the
grease fitting adaptor about three turns to allow
grease to flow out of the cylinder.
2. As soon as the right track sag is obtained, tighten
the adaptor. See Track Tension Value.
WARNING: Never unscrew the grease fitting
adaptor completely to speed up the flow of
grease. The grease in the cylinder is under
high pressure.
