Control functions Rear shock absorber To adjust the air pressure 1. Place the snowmobile on a level surface and apply the parking brake. 2. Lift the rear of the snowmobile onto a suitable stand to raise the drive track off the ground. 3. Remove the air valve cap from the shock absorber. TIP 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 connected and tightened onto the air valve. To decrease the air pressure, push the black bleed valve button.

Rear shock absorber
To adjust the air pressure
1.
Place the snowmobile on a level surface
and apply the parking brake.
2.
Lift the rear of the snowmobile onto a suit-
able stand to raise the drive track off the
ground.
3.
Remove the air valve cap from the shock
absorber.
4.
Install the hose connector of the shock
absorber pump onto the air valve of the
shock absorber, tighten it approximately
six turns until the pressure registers on
the pump gauge, and then pull the hose
connector lock lever up.
NOTICE:
Do not
overtighten the connector onto the air
valve as this will damage the connec-
tor seal.
[ECS00721]
TIP
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 connected and tight-
ened onto the air valve. To decrease the
air pressure, push the black bleed valve
button.
NOTICE:
Do not exceed 1406
kPa (14.1 kgf/cm², 200 psi).
