Break-In Period

Engine Break-In

The break-in period for your new snowmobile is defined as the first ten 
hours of operation, or the time it takes to use the first two tanks full of 
gasoline. No single action on your part is as important as a proper break-
in period. Careful treatment of a new engine will result in more efficient 
performance and longer life for the engine.

NOTICE: Excessive heat build-up during the first three hours of operation will 

damage close-fitted engine parts. Do not operate at full throttle or high 
speeds during the first three hours of use.

1. Fill the fuel tank with gasoline.

2. Check the oil level. See page 61.

3. Drive slowly at first. Select an area that's open and will allow room 

to familiarize yourself with vehicle operation and handling.

4. Vary the throttle positions. Do not operate at sustained idle.

5. Perform regular checks on fluid levels, controls and areas outlined 

on the daily pre-ride inspection checklist. See pages 19 and 25.

6. Change the oil after the first 20 hours of operation.

Operation

Fuel

When refueling, use either leaded or unleaded gasoline with a minimum 
pump octane number of 87=(R+ M)/2 octane. Do not use E-85 fuel.

WARNING

Gasoline is highly flammable and explosive under certain conditions.

• Always exercise extreme caution whenever handling gasoline.

• Always refuel with the engine stopped, and outdoors or in a well ventilated 

area.

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

refueling is performed or where gasoline is stored.

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

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

and water and change clothing.

• If you get gasoline in your eyes or if you swallow gasoline, see your doctor 

immediately.

• 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.

• Turn the fuel valve off whenever the vehicle is stored or parked.

WARNING

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