Compression damping force adjustment (FX10)
The compression damping force can be adjusted
by turning the adjusting knob 1.

* With the adjusting knob fully turned lightly in

direction

CAUTION:

• Do not continue to turn the adjusting knob in

direction

a after it stops. The shock absorber

can be damaged and compression damping
force adjustments cannot be made.

• Do not turn the adjusting knob in direction

more than 12 clicks. Even if the adjusting
knob is continually turned after 12 clicks,
there will be no change in the compression
damping force.

• Be sure to stop the adjusting knob at a posi-

tion where there is a click.

• The damping forces for the left and right ski

shock absorbers must be adjusted to the
same settings. Uneven settings can cause
poor handling and loss of stability.

Air pressure adjustment (FX10RT/FX10RTR/
FX10RTRA)

CAUTION:

The left and right shock absorber air pressure
must be set to the same setting. Uneven set-
tings can cause poor handling and loss of sta-
bility.

This snowmobile is equipped with FOX shock
absorbers as standard equipment.
The air pressure of the shock absorbers can be
adjusted using the shock absorber pump 1
included with your snowmobile.

FRONT SUSPENSION

Adjustment steps:

WARNING

Support the snowmobile securely on a suitable
stand before adjusting the shock absorbers.

CAUTION:

Make sure that there is no load on the shock
absorbers and that they are fully extended
before making any air pressure adjustments.

• Place the snowmobile on a level surface and

apply the parking brake.

• Lift the front of the snowmobile onto a suitable

stand to raise the skis off the ground.

• Remove the air valve cap 1 from the shock

absorber.

• Install the hose connector 2 of the shock

absorber pump onto the air valve of the shock
absorber and tighten it approximately six
turns until the pressure registers on the pump
gauge.

CAUTION:

Do not overtighten the connector onto the air
valve as this will damage the connector seal.

NOTE:

If the shock absorber has no air pressure, the
gauge reading will be zero.

• To increase the air pressure, operate the

pump a few times. The pressure should
increase slowly. If the pressure increases rap-
idly, check to make sure that the pump is
properly connected and tightened onto the air
valve. To decrease the air pressure, push the
bleed valve button 3.

NOTE:

To allow pressure to escape from the pump and the
shock absorber, push the button halfway down and
hold it. To allow only a small amount of pressure to
escape, push the button all the way down and
quickly release it.

• Remove the hose connector from the air

valve.

NOTE:

When removing the connector, the sound of air
escaping may be heard, but this is from the pump
hose, not the shock absorber.

FRONT SUSPENSION/REAR SUSPENSION

CAUTION:

Do not exceed 1,034 kPa (10.3 kg/cm², 150 psi).

• Install the air valve cap.

NOTE:

If the front suspension bottoms too easily or rolls
too much during cornering, increase the air pres-
sure by 34 kPa (0.3 kg/cm², 5 psi). If the suspen-
sion is too firm and you want a more compliant ride,
decrease the air pressure by 34 kPa (0.3 kg/cm², 5
psi).

Air pressure range:

345 kPa (3.4 kg/cm², 50 psi) to 1,034 kPa
(10.3 kg/cm², 150 psi)

Recommended air pressure:

517 kPa (5.3 kg/cm², 75 psi)

REAR SUSPENSION

Stopper band

1. Adjust:

• Stopper band length

CAUTION:

Make sure the left and right rear suspension
stopper bands are adjusted evenly. (FX10MT/
FX10MTR/FX10MTRA)

NOTE:

This adjustment affects the handling characteristics
of the snowmobile.

REAR SUSPENSION

Adjustment steps:

• Remove the stopper band bolts 1, nuts and

washers.

• Adjust the length of the stopper bands 2 by

inserting the bolts in different holes.

• Tighten the stopper band nuts.
