MAINTENANCE
Polaris Variable Transmission (PVT) System
Failure to comply with the instructions in this warning can result in severe
injury or death.
Do not modify any component of the PVT system. Doing so may reduce its
strength so that a failure may occur at a high speed. The PVT system has
been precision balanced. Any modification will cause the system to be out of
balance, creating vibration and additional loads on components.
The PVT system rotates at high speeds, creating large amounts of force on
clutch components. Extensive engineering and testing has been conducted
to ensure the safety of this product. However, as the owner, you have the
following responsibilities to make sure this system remains safe:
• Always follow all recommended maintenance procedures. See your dealer
as outlined in the owner's manual.
• This PVT system is intended for use on Polaris products only. Do not install
it in any other product.
• Always make sure the PVT housing is securely in place during operation.
When To Use Low Range vs. High Range
Belt slip is responsible for creating excessive heat that destroys belts,
wears clutch components and causes outer clutch covers to fail. Switch
to low range while operating at slower speeds to extend the life of the
PVT components (belt, cover, etc.).
Operating at speeds less than 7 MPH (11 km/h)
Towing heavy loads
Operating in rough terrain (swamps, mountains, etc.)
Operating at speeds greater than 7 MPH (11 km/h)
