Gas Pressure Adjustment
Nitrogen (N
2
) can now be added to damper body.
Reinstall Schrader valve using teflon tape on valve
threads into damper body.
Preset your pressure regulator to 2070 kPa (300
PSI) nitrogen (N
2
), this gas pressure will restore
the correct pressure for your damper.
CAUTION : Do not exceed the recom-
mended pressure values.
WARNING : Whenever working with high
pressure gas, use eye wear protection.
Never direct gas pressure toward anybody.
NOTE : Carefully inspect damper for gas or
oil leaks. Any leaks must be corrected before
continuing.
Damper gas pressure can be confirmed by using
a pressure gauge available through your local in-
dustrial gas supplier.
1. Automotive type air pressure hose
2. Two stage regulator, delivery pressure range 2070 KPa (300 PSI)
3. High pressure cylinder filled with industrial grade nitrogen
4. Valve tip
Reinstall damper spring retainer, then your spring.
Next, thread the spring pre-load rings up to the
spring. Set pre-load according to recommended
spring length specifications. Your damper is now
ready for reinstallation to your snowmobile.

Miscellaneous Information
– Never substitute the nitrogen gas fill for anoth-
er gas product. The nitrogen gas has been se-
lected because of its inert qualities. As well as
being a dry gas (moisture free), it will not con-
taminate the gas chamber portion of the damp-
er.
