FEATURES AND CONTROLS
Throttle Lever
WARNING
Operating an ATV with sticking or improperly operating throttle controls could
cause an accident. Never start or operate an ATV that has a sticking or
improperly operating throttle. Always contact your dealer for service before
operating the vehicle.
Failure to check or maintain proper operation of the throttle system can result in
an accident if the throttle lever sticks during operation. Always check the lever
for free movement and return before starting the engine. Also check
occasionally during operation.
Modifications to the electronic throttle control could result in failure to perform as
designed, which could result in an accident. Do not attempt to modify the throttle
control system or replace it with any after market throttle mechanisms. Always
ensure that the throttle cable is properly installed to the throttle control.
Engine speed and vehicle
movement are controlled by
pressing the throttle lever.
The throttle lever is spring
loaded. Engine speed
returns to idle when the
lever is released.
This ATV is equipped with
Polaris Electronic Throttle
Control (ETC), which is
designed to reduce the risk of a frozen or stuck throttle. If the throttle
cable should stick in an open position when the operator releases the
throttle lever, the engine will stop, and power to the rear wheels will
cease.
