MAINTENANCE
Throttle System
Failure to check or maintain proper operation of the throttle system can result in an accident and lead to
serious injury or death if the throttle pedal sticks during operation.
Always check the pedal for free movement and return before starting the engine and occasionally
during operation. Never start or operate this vehicle if it has a sticking or improperly operating throttle
pedal. Immediately contact your dealer for service if throttle problems arise.
Throttle Freeplay
If the throttle pedal has excessive play due to cable stretch or
misadjustment, it will cause a delay in throttle response,
especially at low engine speed. The throttle may also not open
fully. If the throttle pedal has no freeplay, the throttle may be
hard to control, and the idle speed may be erratic.
Check the throttle pedal freeplay at the intervals outlined in
the Periodic Maintenance Chart beginning on page 65. Adjust
the freeplay if necessary.
Throttle Freeplay Inspection
1. Apply the brakes. Engage the park brake. Shift the transmission to neutral.
2. Start the engine. Allow it to warm up thoroughly.
3. Measure the distance the throttle pedal moves before the engine begins to pick up speed.
Freeplay should be 1/16 to 1/8 inches (1.6-3.2 mm).
Idle RPM
Idle RPM is preset by the manufacturer. If the engine idle speed is not satisfactory, please see
your POLARIS dealer for adjustment.
Throttle Freeplay Adjustment
1. Unlatch the cargo box.
2. Locate the throttle cable adjuster.
3. Squeeze the end of the rubber boot and slide it far
enough to expose the end of the inline cable adjuster.
4. Loosen the adjuster lock nut.
5. Rotate the boot to turn the adjuster until 1/16 to 1/8
inches (1.6-3.2 mm) of freeplay is achieved at the
throttle pedal.
Tip: While adjusting, lightly flip the throttle pedal up and down.
6. Tighten the lock nut.
7. Squeeze the end of the rubber boot and slide it over
the cable adjuster to its original position.
