Starting A Warm Engine; Cold Weather Operation - Polaris Sportsman 450 Owner's Manual

Starting the Engine

Starting a Warm Engine

Warm engines do not normally require the use of the choke. Using the
choke can cause the spark plug to become wet fouled.
1. Position the vehicle on a level surface with the transmission in
PARK.
2. Lock the parking brake, turn the fuel tank valve on, sit on the
vehicle, and turn the engine stop switch to RUN.
3. If the engine has cooled to a point where it does not readily start,
intermittent use of the choke (knob pulled half way out) may be
necessary.
4. If the engine is over-choked when warm, depress the throttle lever
fully while cranking to aid in starting.
5. 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.

Cold Weather Operation

If the ATV is used year-round, check the oil level frequently. A rising
oil level could indicate the accumulation of contaminants such as water
or excess fuel in the bottom of the oil tank. Water in the bottom of the
tank 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.
