POLARIS ELECTRONIC
REVERSE CONTROL (PERC)
OPERATION
Some models are equipped with Polaris electric reverse
control (PERC). The operation of the electronic reverse
system is achieved by automatically reversing the engine
rotation with a push of a button. When in reverse you will
have an indicator light that will flash, notifying you that the
machine is in the reverse mode. The design of the clutches are
matched to the specifications that will allow the backwards
rotation of the engine to move the sled in reverse. To get back
to forward is as easy as pushing the button again.
REVERSE OPERATION
1. Ensure that the vehicle is stopped and the engine is
warmed up and running at idle.
NOTE: The system will only engage in reverse if the
engine is below 4000 RPM. If engine is above 4000
RPM the system can not be activated.
2. Ensure that the path behind you is clear.
3. Push and hold the yellow reverse button on the left hand
control for 1 second and then release the button. 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.
4. Ensure that the path behind you is clear.
5. Slowly apply throttle until the sled starts to move in
reverse, and carefully direct the sled in the direction that
you want.
NOTE: Maximum RPM in reverse is 6000 RPM.
NOTE: If the engine stops running or is shut off
while in reverse. The engine will start in forward
gear.
FORWARD OPERATION
1. If unit was operated in reverse, ensure that the path ahead
is clear, and push an hold the reverse button for 1 second
and then release the button. The engine will now
automatically change direction form reverse to forward
and the reverse light on the instrument panel will stop
flashing.
NOTE: When servicing clutches, ensure that the
vehicle is in forward gear. If not damage to the
driven clutch may occur when removing the belt.
ALTITUDE SETTING
If your engine is carbureted, you can adjust the elevation
setting of the Polaris electric reverse control (PERC). If your
engine is a Cleanfire system, this is automatically done
through the engine controller unit (ECU), and you do not need
to do any setting.
At higher elevations over 6000 ft (1829m), the engine requires
a different ignition RPM setting to improve the operation of
the reverse system.
To set the altitude settings:
1. With the engine running, push and hold the reverse button
for 5 - 6 seconds and then release the button.
2. The reverse light will flash rapidly on the instrument
panel.
3. You have now set the PERC system to the higher elevation
setting.
4. To go back to the low elevation setting repeat step 1. The
reverse light will flash slowly indicating that the system is
now in the lower elevation setting.
NOTE: The elevation setting will be set in the
memory (engine running or not) until it is changed.
PERC NOTES
• Max RPM for shifting into reverse = 4000 RPM
• Max RPM for operating in reverse = 6000 RPM
• Engine must first reach 900 RPM at start up before the
reverse system can be used. The system works between
900 and 4000 RPM.
• If the button is pushed above 4000 RPM the system is
bypassed and nothing will happen.
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 run-
ning.
