Adjusting Fox Air Shocks
(Sno Pro Models)

NOTE: It is recommended to moni-
tor the air pressure in the air shocks
once every month.

NOTE: Adjusting air shocks may
be done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
The air shocks are individually adjustable
for the terrain conditions and driving
style of the operator. The shocks are pre-
set at the factory (see chart) as an initial
setting; however, it is possible to “fine
tune” the shocks to match the operator’s
weight, riding style, and terrain condi-
tions.

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 snow-
mobile.
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 0.14-3.52 kg/cm
2
(2-5
psi).
3. To decrease air pressure in the
shock, press the black bleed valve
button half way down and hold until
desired pressure is attained.

NOTE: Pressing the button fully
down and releasing it will allow only
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.
