ELECTRONIC REVERSE (PERC)

Operation

WARNING
Reverse operation, even at low speeds, may cause
loss of control, resulting in serious injury or death. To
avoid loss of control, always:
LOOK BEHIND BEFORE AND WHILE BACKING.
AVOID SHARP TURNS.
SHIFT TO OR FROM REVERSE ONLY WHEN
STOPPED.
APPLY THROTLE SLOWLY.
CAUTION
To avoid personal injury and/or engine damage, do not
operate the electric start or recoil while engine is
running.
1. Ensure that the vehicle is stopped and the engine is
warmed up and running at idle.
NOTE: PERC will not engage below 900 RPM or above
4000 RPM.
2. Push and release the yellow reverse button on the left
hand control. The reverse light on the instrument
panel will flash when engine is in reverse motion.
NOTE: The engine will automatically reduce RPM and
it will reverse the rotation of the engine when the RPM
is at the lowest RPM point.
3. Ensure that the path behind the snowmobile is clear.
4. Slowly apply throttle until the sled starts to move in
reverse. Carefully direct the sled in the desired
direction.
NOTE: If the engine stops running or is shut off while
in reverse. The engine will start in forward gear.

FORWARD OPERATION

release the reverse button. The engine will
automatically change direction form reverse to
