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.
• Place the snowmobile on a level surface and
apply the parking brake.
• Lift the front of the snowmobile onto a suitable
stand to raise the skis off the ground.
• Remove the air valve cap
1
from the shock
absorber.
• 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.
• To increase the air pressure, operate the
pump a few times. The pressure should
increase slowly. If the pressure increases rap-
idly, check to make sure that the pump is
properly connected and tightened onto the air
valve. To decrease the air pressure, push the
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.
• Remove the hose connector from the air
valve.
NOTE:
When removing the connector, the sound of air
escaping may be heard, but this is from the pump
hose, not the shock absorber.
