PZ50 / PZ50MT / PZ50VT
To increase the spring preload and thereby
harden the suspension, turn the adjusting ring
in direction (a). To decrease the spring pre-
load and thereby soften the suspension, turn
the adjusting ring in direction (b).

1. Loosen the locknut.
2. To increase the spring preload and there-
by harden the suspension, turn the ad-
justing nut in direction (a). To decrease
the spring preload and thereby soften the
suspension, turn the adjusting nut in di-
rection (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.

handling and loss of stability.
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
included with your snowmobile.
