switch down to stop the engine.  Pull it up to allow restarting.

n

Ignition Switch

Make sure the engine stops when the ignition switch is turned to OFF.

n

Tether Switch

If your machine has a tether switch, remove the tether from the switch to 

make sure the engine stops immediately.

n

Lighting

Check the headlight (high and low beam), taillight, and brake light.  

Replace burned out lamps before operating.

n

Mirror Adjustment (if equipped)

Adjust the mirrors so they can be used to their full advantage.

n

OPERATION

Starting the Engine

Starting a Cold Engine (Manual Start)

Do not depress the throttle until 

the engine starts.

1. Turn the fuel valve on. See 

page 29.

2. Turn the key to the ON 

position.

3. Pull the engine stop switch 

up to the RUN position.

4. Flip the choke toggle to 

FULL ON.

5. Grasp the recoil rope han-

dle and pull slowly until 

the recoil engages; then 

pull abruptly.

6. Repeat as needed until the engine starts.

7. After the engine starts, flip the choke toggle to the OFF position.  If 

the engine slows or wants to stop, use intermittent choking to the 

HALF ON position.

WARNING

Before starting the engine, always refer to all safety warnings pertaining to 

snowmobile operation.  Never start your snowmobile without checking all 

components to be sure of proper operation.  See Before Starting the Engine 

beginning on page 63.

WARNING

Don't pull the starter rope to the fully extended position and don't allow it to 

snap back into the housing.  Damage may result.
To avoid injury and/or engine damage, do not operate the electric starter or 

pull-rope starter while the engine is running.

OPERATION

Starting the Engine

Starting a Warm Engine

1. Turn the key to the ON position.
2. Pull the engine stop switch up to the RUN position.
3. Grasp the recoil rope handle and pull slowly until the recoil 

engages; then pull abruptly.

If the engine does not start on the first pull, slightly depress the throttle 

with your left hand (no more than 1/4I open), and pull the rope with 

your right hand.  When the engine starts, immediately release the throt-

tle.

Engine Break-In

No single action on your part is as important to long, trouble-free 

machine life as proper break-in of a new or rebuilt engine.  Premix the 

first tank of fuel with one pint of Polaris injection oil for each five gal-

lons of fuel. This, in addition to the lubrication supplied by the injection 

system, will assure proper engine break-in.

CAUTION

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 for 

extended periods during the first three hours of use.  Vary the throttle open-

ings and machine speeds to reduce friction on all close-fitting machined 

parts, allowing them to break in slowly without damage.
Use of any lubricants other than those recommended by Polaris may cause 

serious engine damage.  We recommend the use of Polaris lubricants for 

your vehicle.
Drive with extra caution during the break-in period.  Perform regular checks 

on fluid levels, lines, and all other important areas of the machine.

OPERATION

Engine Break-In

Oil Injection System

Always check and fill the oil tank when refueling.  See page 75.

Oil Recommendations

This snowmobile is equipped with a variable exhaust system (VES). 

Engine lubrication comes from oil added to the fuel and oil injection 

systems.  Polaris recommends the use of VES II 2 Cycle Oil for this 

engine.  See page 124 for the part numbers of Polaris products.

Never mix brands of oil.  Serious chemical reactions can cause injection 

system blockage, resulting in serious engine damage.  Oils 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.

Slide Rail and Track Cooling

CAUTION

Serious engine damage can occur without the proper lubrication. Check the 

oil tank level often during the first tank of fuel.  If the oil level doesn't go down, 

contact your dealer immediately.

CAUTION

Inadequate cooling and lubrication will lead to overheating of the slide rail 

and track, resulting in premature wear and failure.  Reduce speeds and fre-

quently drive into fresh snow to allow adequate cooling and polishing of the 

slide rail and track surfaces. Avoid operating on ice, hard-packed surfaces or 

roads.
