TIP
To allow pressure to escape from the pump
and the shock absorber, push the button half-
way down and hold it. To allow only a small
amount of pressure to escape, push the but-
ton all the way down and quickly release it.
6. Push the hose connector lock lever
down, and then remove the hose connec-
tor from the air valve.
TIP
When removing the connector, the sound of
air escaping may be heard, but this is from the
pump hose, not the shock absorber.
7. Install the air valve cap.
TIP
If the shock absorber bottoms too easily or
rolls too much during cornering, increase the
air pressure by 34 kPa (0.3 kgf/cm², 5 psi). If
the shock absorber is too firm and you want a
more compliant ride, decrease the air pres-
sure by 34 kPa (0.3 kgf/cm², 5 psi).
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.
Control functions
1. Air valve cap
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.

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-
