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 Inspection
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 57.
Adjust the freeplay if necessary.
1. Place the transmission in PARK.
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).
Throttle Body/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. Remove the seat.
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" (1.5-3
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.
