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.
Snowmobile handling and comfort de-
pend upon suspension adjustments.
Choice of suspension adjustments
vary with carrying load, driver's weight,
personal preference, riding speed and
field condition.
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.
– Make sure support device is sta-
ble and secure.
Customize each adjustment one at
a time. It may be necessary to read-
just center spring after adjusting front
springs for instance. Test run the
snowmobile under the same condi-
tions; trail, speed, snow, driver riding
position, etc. Change one adjustment
and retest. Proceed methodically until
you are satisfied.
