OPERATION

Fuel Safety

Gasoline is highly flammable and explosive under certain conditions.

• Always exercise extreme caution whenever handling gasoline.

• Always refuel outdoors or in a well-ventilated area. 

• Always turn off the engine before refueling.

• Do not overfill the tank. Do not fill the tank neck.

• Do not smoke or allow open flames or sparks in or near the area where refu-

eling is performed or where gasoline is stored.

• If gasoline spills on your skin or clothing, immediately wash it off with soap 

and water and change clothing.

• Never start the engine or let it run in an enclosed area. Engine exhaust fumes 

are poisonous and can cause loss of consciousness or death in a short time.

The engine exhaust from this product contains chemicals known to cause 
cancer, birth defects or other reproductive harm. Operate this vehicle only 
outdoors or in well-ventilated areas.

OPERATION

Fuel

For peak performance, POLARIS recommends the use of 91 octane or 
higher fuel. Although 87 octane fuel is usable, some engine 
performance will be lost and fuel economy will decrease. Do not use 
lower than 87 octane fuel. Do not use fuel containing more than 10% 
ethanol (including E85).

NOTICE: Operating with obstructed fuel systems will result in serious engine 

damage. Perform maintenance as recommended.

Prolonged exposure to petroleum based products may damage paint. 
Always protect painted surfaces when handling fuel.

Fuel System Deicers

If you use non-oxygenated fuel, POLARIS recommends the regular use 
of isopropyl-based fuel system deicer. Add one to two ounces per gallon 
(8-16 ml per liter) of gasoline to prevent engine damage resulting from 
fuel system icing and lean fuel mixtures. Never use deicers or additives 
containing methanol. POLARIS also recommends the use of Carbon 
Clean. See page 122 for the part numbers of POLARIS products. 

If you use oxygenated fuel containing ethanol, additional alcohol 
deicers or water absorbing additives should not be used.

OPERATION

Oil

Low Oil Indicator Light

The low oil indicator light may flicker at times due to oil movement in 
the bottle, but when the light comes on and remains on, add the 
recommended oil before further operation. See page 72 for oil 
recommendations.

Visually check the oil level in the bottle. The engine may be operated as 
long as oil is visible in the oil tank. If oil is not visible, continued 
operation may cause serious engine damage.

Never mix brands of oil. Serious chemical reactions can cause injection 
system blockage, resulting in serious engine damage. They may also be 
incompatible and the result could be sludge formation, filter blockage, 
and reduced cold weather flow rates. All POLARIS oils are compatible 
with each other.

Always maintain the oil level above the tank’s low level line. This is 
especially important when the snowmobile is operated in mountainous 
terrain. Maintaining the proper oil level will prevent system aeration and 
possible loss of pumping action, which could result in engine damage.

NOTICE: Mixing brands or using a non-recommended oil may cause serious 

engine damage. We recommend the use of POLARIS 2-cycle oils for 
your snowmobile. Never mix brands.

Operating the snowmobile without proper engine lubrication can result 
in serious engine damage. Always check the oil level when refueling.

Low Oil Level

Always do a visual check of the oil level when refueling. When the oil 
reaches the low level mark, add the recommended oil to the tank. 

The POLARIS oil cap on the oil bottle is vented to allow proper oil 
flow. See your POLARIS dealer for recommended replacement parts.

OPERATION

Engine Stop Switch

Push down on the engine stop 
switch to ground out the ignition 
and stop the engine quickly. Pull the 
switch up to the RUN position to 
allow restarting.

Throttle Safety Switch

The throttle safety switch is designed to stop the engine whenever all 
pressure is removed from the throttle lever and the throttle cable or 
valves do not return to the normal closed position.

WARNING! Operating the snowmobile with a faulty throttle safety switch can 
result in serious injury or death in the event of an accident. If the throttle safety 
switch does not shut off the engine during a carburetor/throttle system 
malfunction, immediately push down the engine stop switch. Do not start the 
engine again until the malfunction has been corrected by your dealer.
