Adjusting the air pressure of the rear
shock absorber (RX10PS)
A shock absorber pump is provided with your
snowmobile to adjust the air pressure of the
shock absorber. This pump is equipped with
an air pressure gauge. One side of the gauge
has a low-pressure meter and the other side
of the gauge has a high-pressure meter. Use
the high-pressure meter to adjust the rear
shock absorber.

TIP
If the shock absorber has no air pressure, the
gauge reading will be zero.
Lift the rear of the snowmobile onto a suit-
able stand to raise the drive track off the
ground.
Remove the air valve cap from the shock
absorber.
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.
