AIR PRESSURE ADJUSTMENT (PZ50RT)
Adjustment steps:
WARNING
Support the snowmobile securely on a suitable
stand before adjusting the shock absorbers.
CAUTION:
Make sure that there is no load on the shock
absorbers and that they are fully extended
before making any air pressure adjustments.
1. Place the snowmobile on a level surface and
apply the parking brake.
2. Lift the front of the snowmobile onto a suitable
stand to raise the skis off the ground.
3. Remove the air valve cap 1 from the shock
absorber.
4. Install the hose connector 2 of the shock
absorber pump onto the air valve of the shock
absorber and tighten it approximately six turns
until the pressure registers on the pump gauge.
CAUTION:
Do not overtighten the connector onto the air
valve as this will damage the connector seal.
NOTE:
If the shock absorber has no air pressure, the
gauge reading will be zero.
5. To increase the air pressure, operate the pump
a few times. The pressure should increase
slowly. If the pressure increases rapidly, check
to make sure that the pump is properly con-
nected and tightened onto the air valve. To
decrease the air pressure, push the black bleed
valve button 3.
NOTE:
To allow pressure to escape from the pump and the
shock absorber, push the button halfway down and
hold it. To allow only a small amount of pressure to
escape, push the button all the way down and
quickly release it.
