BATTERY/ELECTRICAL SYSTEM
STORAGE
Never leave a battery unattended during the storage
season. Snowmobile batteries are small and cannot
maintain their charge over the storage season. To ensure
your battery maintains its level of charge, the battery
should be connected to a battery tender/trickle charger. If
equipped, use the battery tender port
q
to maintain the
charge on the battery.
NOTICE
Image for reference only.
1. While the battery can remain installed on the
snowmobile, it is recommended the battery be
removed from the snowmobile and stored in a cool,
and dry location. Removing the battery from the
snowmobile facilitates off-site storage of the
snowmobile where electricity may not be available to
connect a battery tender. In addition, removing the
battery allows access to other maintenance items,
such as the chaincase chain tensioner bolt.
2. Connect a Polaris battery tender or equivalent
commercially available tender to the battery.
3. Inspect the electrical connections and wire harnesses
throughout the snowmobile. If damage is found, make
a note of the damage so that you and your authorized
Polaris dealer can address the concern.
CHAINCASE
Never leave ‘used’ lubricant in the chaincase during the
storage season. Doing so may leave water present in the
chaincase which may cause corrosion and rust.
1. Follow the Owner’s Manual procedures and drain / fill
the chaincase with new Polaris SCL (Synthetic
Chaincase Lubricant). All Polaris PRO-RIDE, AXYS,
and MATRYX snowmobile feature ‘fill-to-spill’
lubricant fill specifications which makes it relatively
‘easy’ to re-fill the chaincase.
2. Rotate the driven clutch in the direction of forward
vehicle travel to move the chain slack to the
tensioner-side of the drive system. Lock the parking
brake.
3. Loosen the drive chain adjuster lock nut. Turn the
adjuster screw inwards until it can no longer be
turned by hand.
4. At this point, turn the adjuster nut ¼ turn counter
clockwise.
5. Tighten and then torque the jam nut to the
specification listed in the Owner’s Manual. Release
the parking brake.
NOTICE
If the snowmobile is equipped with a transmission
(Titan / WideTrak snowmobiles), there is not a drive
chain adjustment procedure.
