 NOTE: When adjusting air pres-
sure, all weight must be removed
from the suspension, and the
shock absorbers must be fully
extended.
 NOTE: Adding air pressure will
increase the air spring force;
reducing air
decrease air spring force.
! WARNING
Do not exceed 10.5 kg/cm
psi) in the shock.
1. Remove the air valve cap from the
shock.
2. Thread the
Absorber Air Pump (p/n 2603-
614) 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/
2
cm (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.
 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.

Skid Frame Front Arm
 NOTE: On some models, the
front arm limiter straps are not
adjustable.
The skid frame front arm shock spring
and limiter straps are adjustable. How-
ever, Arctic Cat recommends that the
shock spring be maintained at the fac-
tory preset of 1/8-1/4 in. preload.
Tightening the skid frame front arm
shock spring may cause improper bal-
ance and may ruin the handling fea-
tures of the snowmobile.
The length adjustment of the front arm
limiter straps determines the weight
distribution between the front of the
skid frame and the skis. Tightening the
limiter strap (shortening the strap) will
pull up on the front of the skid frame
and will increase ski pressure. Loosen-
ing the limiter strap (lengthening the
strap) lowers the front of the skid frame
and decreases ski pressure.
When customizing the amount of ski
pressure, be sure to adjust both straps
equally and do not over-adjust the lim-
iter straps to adversely affect steering
and operator control of the snowmobile.
Some experimentation may be required
until the proper adjustment for the oper-
ator's individual style is obtained.
 NOTE: If the limiter straps are
adjusted, it
mended that at least a minimum of
1/8 in. preload on the shock spring
be maintained.
! WARNING
Do not adjust the front arm limiter
straps to a point at which steering
and operator control of the snow-
mobile are adversely affected.
