Starting the Engine
11. Turn the ignition key past the ON position to engage the starter.
Activate the starter for a maximum of five seconds, releasing the
key when the engine starts.
NOTICE: Operating the vehicle immediately after starting could cause engine
damage. Allow the engine to warm up for several minutes before
operating the vehicle.
12. If the engine does not start, return the key to the OFF position and
wait five seconds before attempting to start again. Activate the
starter for another five seconds if necessary. Repeat this procedure
until the engine starts.
Tip: If a warm engine has cooled to a point where it does not readily start, inter-
mittent use of the choke button (pulled half way out) may be necessary. If
the engine is over-choked when warm, depress the throttle lever fully while
cranking to aid in starting. Release the throttle lever immediately after the
engine starts. If the engine does not start and all conditions are favorable,
change the spark plug and try again.
13. If the engine slows or stops, position the choke knob half way in to
allow proper engine warm up. Vary the engine RPM slightly with
the throttle to aid in warm-up. When the engine idles smoothly,
push the choke completely in.

Cold Weather Operation

If the ATV is used year-round, check the oil level frequently. A rising oil
level could indicate the accumulation of contaminates such as water or
excess fuel in the bottom of the crankcase. Water in the bottom of the
crankcase can lead to engine damage and must be drained. Water accu-
mulation increases as outside temperature decreases.
See your Polaris dealer for engine heater kits, which provide quicker
warm-ups and easier starting in colder weather.
