WARNING
EWS00750
The left and right spring preloads must be
adjusted to the same setting. Uneven set-
tings can cause poor handling and loss of
stability.
To increase the spring preload and thereby
harden the suspension, turn the adjuster in di-
rection (a). To decrease the spring preload
and thereby soften the suspension, turn the
adjuster in direction (b).

Adjusting the air pressure of the cen-
ter shock absorber and the rear shock
absorber (FX10M53S/FX10M62S)
A shock absorber pump is provided with your
snowmobile to adjust the air pressure of the
shock absorbers. 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 low-pressure meter to adjust the center
shock absorber and the high-pressure meter
to adjust the rear shock absorber.
