4.
A track that is properly adjusted may have a different sag
according to the track options. Contact your dealer for
information.
5.
The track tension can be adjusted with the grease fitting
valve (1, Figure 138) and handle screws (2, Figure 138) in
the center of each side frame. Filling the grease fittings
with grease increases the length of the adjustable
cylinders. The longer the adjustable cylinders become, the
more pressure builds in the tension springs which expand
beyond the track idlers.
6.
If the tracks and adjustment devices expand to the point
that there is a lack of deflection or space between parts,
turn the handle screw clockwise once or twice to drain
some of the grease. Once the track tension is suitable,
tighten the handle screw in the counterclockwise direction.
•
Grease fitting valve tightening torque: 68.6 ±9.8 N.m
(7 kg ±1 kg.m, 5.2 ±0.7 ft lb)
•
Check the tension again after rotating the track 3 ~ 4
times.
NOTE:
After draining, failure to turn the handle screw
counterclockwise will allow the grease to keep
draining.
Also, turning it too far counterclockwise may
cause damage to the stopper of the screw.
Turn the handle screw by no more than one or
two turns.

WARNING
AVOID DEATH OR SERIOUS INJURY
The track adjusting mechanism is under very
high-pressure. NEVER release grease pressure too
fast. The track tension grease valve should never be
loosened more than one (1) complete turn from the
fully tightened down position. Bleed off grease
pressure slowly. Keep your body away from the valve
always. Always wear eye and face protection when
adjusting track tension.
