The air shocks are individually adjustable
for the terrain conditions and driving style
of the operator. The shocks are preset at the
factory (see chart) as an initial setting;
however, it is possible to “"fine tune”" the
shocks to match the operator’' s weight, rid-
ing style, and terrain conditions.

NOTE: Adding air pressure will
increase the air spring force; reduc-
ing air pressure will decrease air
spring force.
Checking and adjusting air pressure must
be done at riding temperature (outside).
Also, it is advisable to check air pressure
when the outside temperature varies
more than 25°.
NOTE: Care should be taken to have
equal pressure in the front (ski) shocks
before operating the snowmobile.

To increase or decrease air pressure, use
the following procedure.
NOTE: When adjusting air pres-
sure, all weight must be removed
from the suspension, and the shock
absorbers must be fully extended.

1. Remove the air valve cap from the
shock.
2. Thread the valve of Shock Absorber
Air Pump onto the shock air valve
approximately six rotations.
NOTE: As the pump is being
attached to the shock, the hose will
fill with air. This will result in a lower
gauge pressure 2-5 psi.

NOTE: Pressing the button fully
down and releasing it will allow only
250 psi (nitro-
a small amount of air to escape

(micro-adjust).
4. To increase air pressure in the shock,
pump until desired pressure is
attained.
5. Remove the pump valve from the
shock air valve.
NOTE: As the pump valve is being
removed from the shock, the sound
of air loss is from the pump hose,
not from the shock.
6. Install the air valve cap onto the
shock.

strap (shortening the strap) will pull up
on the front of the skid frame and will
increase ski pressure. Loosening the lim-
iter strap (lengthening the strap) lowers
the front of the skid frame and decreases
ski pressure.
