OPERATION Starting the Engine 7. Do not press the throttle while starting the engine. Turn the ignition key past the POSITION LIGHTS ON position to engage the starter. Activate the starter for a maximum of five seconds, releasing the key when the engine starts. 8. If the engine does not start, release the starter and wait five seconds. 9. Repeat steps 7 and 8 until the engine starts. Operating the vehicle immediately after starting could cause engine damage. Allow the engine to warm up for several minutes before operating. 10. If a warm engine has cooled to a point where it does not readily start, intermittent use of the choke (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. 11. 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 Internal engine condensation increases as outside temperatures decrease. If the vehicle 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 accumulation increases as outside temperature decreases. See your Polaris dealer for engine heater kits, which provide quicker warm-ups and easier starting in colder weather. 55

OPERATION
Starting the Engine
7.
Do not press the throttle while starting the
engine. Turn the ignition key past the
POSITION LIGHTS ON position to
engage the starter. Activate the starter for
a maximum of five seconds, releasing the
key when the engine starts.
8.
If the engine does not start, release the
starter and wait five seconds.
9.
Repeat steps 7 and 8 until the engine starts.
Operating the vehicle immediately after starting could cause engine damage.
Allow the engine to warm up for several minutes before operating.
10.
If a warm engine has cooled to a point where it does not readily
start, intermittent use of the choke (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.

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
Internal engine condensation increases as outside temperatures
decrease. If the vehicle is used year-round, check the oil level fre-
quently. A rising oil level could indicate the accumulation of contami-
nates 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 accumulation increases as outside temperature decreases.
See your Polaris dealer for engine heater kits, which provide quicker
warm-ups and easier starting in colder weather.
