Snowmobile handling and comfort de-
pend upon suspension adjustments.
WARNING
Suspension adjustment could af-
fect vehicle handling. Always take
time to familiarize yourself with
the vehicle's behavior after any
suspension adjustment have been
made. Always adjust LH and RH
suspension components to the
same setting.
Choice of suspension adjustments
vary with carrying load, operator's
weight, personal preference, riding
speed and field condition.
NOTE: Some adjustments may not ap-
ply to your snowmobile.
WARNING
Before proceeding with any sus-
pension adjustment, remember:
– Park in a safe place.
– Remove the tether cord cap
from the engine cut-off switch.
– Use appropriate lifting device or
have assistance to share lifting
stress. If a lifting device is not
used, use proper lifting tech-
niques, notably using your legs
force.
– Do not attempt to lift the front or
rear of vehicle if it is above your
limits.
– Support front of vehicle off the
ground with a suitable device
before adjusting suspension.
– Support rear of vehicle off the
ground with a wide-base snow-
mobile stand with a rear deflec-
tor panel.

ble and secure.
The best way to set up the suspen-
sion is to customize each adjustment
one at a time. Various adjustments
are interrelated. It may be necessary
to readjust center spring after adjust-
ing front springs for instance. Test run
the snowmobile under the same con-
ditions; trail, speed, snow, operator
riding position, etc. Proceed methodi-
cally until you are satisfied.
Following are guidelines to fine-tune
suspension. Use suspension adjust-
ment tool provided in the tool kit.
