SAFETY IN

MAINTENANCE

Observe the following
precautions:

• Throttle mechanism should be
checked for free movement before
starting engine.

• Engineshould be running only when

pulley guard is secured in place.

• Never run engine without drive belt

installed. Running an unloaded en-

gine can prove to be dangerous.

• Never run engine when the track of

the vehicle is raised

off

the ground.

• It can be dangerous to run engine

with the cab opened.

• Since engine cooling is fully in ef-

fect only when the vehicle is in mo­tion and driven on snow, it is not
recommended that you allow the
engine to idle for move than brief
periods

and/

or you drive the vehicle
on icy surface. Prolonged idling
and/or

continuous driving on ice

may cause engine damage.

• Gasolineis flammable and explosive
under certain conditions. Always
perform procedures in a well ventila­ted area. Do not smoke or allow
open flames or sparks in the vicinity.

If gasoline fumes are noticed while
driving, the cause should be deter­mined and corrected

without

delay.

• Your snowmobile is not designed to
be operated on public streets, road

or highways. In most States and

Provinces,

it is considered 'an illegal

operation.

• Maintain

vour vehicle in top mecha-

nical condition at all times.

• Your snowmobile is not designed to
be driven or operated on black top,
bare earth, or other abrasive sur­faces. On such surfaces abnormal
and excessive wear of critical parts
is inevitable.

• Only

perform procedures asdetailed
in this manual. Unless otherwise
specified, engine should be turned
OFF for all lubrication and mainte­nance procedures.

• Installation of other than " stock"e­quiprnent, including ski-spreaders,
bumpers, pack racks, etc., could
severelyaffect the stability and safe­ty of your vehicle. Avoid adding on
accessories that alter the basic ve­hicle configuration.

• When removing coolant tank cap,
first place a cloth over cap then turn
cap to its first step to release pres­sure. Never drain or refill the cooling
system when engine is hot.

• The snowmobile engine can be
stopped by activating the emergen-

cy cut-out switch, tether switch or
by turning

off

the key.

• This vehicle is designed for the

driver only. No provisions have been
made for a passenger.

Please

read and understand all other

warnings contained elsewhere.

ToolBox

Located under the cab. To gain access,

tilt

cab. Ideal location for spare plugs,

belt, rope, etc.

FuelGauge

The fuel gauge is located on the left

side of the fuel tank. The gauge func-

tions on the principle of communicat­ing vessels, so the fuel level inside the
tank is directly related

with

the level in-

dicated on the gauge.

..&. WARNING: Never usea lit match

...

or open flame to check fuel level.

BREAK-IN PERIOD

With Bombardier-Rotax snowmobile
engines, a break-in period is required

before running the vehicle at full throt­tle. Engine's manufacturer recommen-

dation is 10to 15operating hours. Dur-

ing this period, a richer mixture is
needed(i.e, 40 parts of gasfor 1part of

50/1 Bombardier oil). Maximum throt-

tle should not exceed

3/4,

however,
brief full acceleration and speed varia­tions contribute to a good break-in.
Continued wide open throttle accelera­tions, prolonged cruising

spe~ds,

and
lugging are detrimental dunng the
break-in period.

1G-Hour Inspection

As with anyprecision pieceof mechan­ical equipement, we suggest,that alter
the first 10 hours of operation or 30
days after the purchase, whichever
comes first, that your vehicle becheck­ed by your dealer. This inspection will

give you the opportunity to discussthe
unanswered questions you mat have
encountered during the first hours of
operation. Remember that it is easier
to remedy at this time than

~o

allow ,the
snowmobile to operate until a possible
failure occurs.

The 10 hours inspection is at the ex-

pense of the vehicle owner.

FUEL

MIXING

Oil must be added to the gasoline in
pre-measured amounts then both oil
and gasoline should be thoroughly
mixed together before fueling the tank.

Recommended Gasoline

The correct gasoline is regular gasoline
available from all service stations.

..,

CAUTION: Never experiment

...

with different fuel or fuel ratios.
Never use naphtha, methanol orsimilar
products.

Recommended Oil

Use concentrated Bombardier snow­mobile oil available from your dealer.
This type of oil has specially formu­lated oil bases to meet the lubrication
requirements of the Bombardier-Rotax
engine.

If Bombardier snowmobile

oil is un­available substitute with a high-quality
2 cycle snowmobile

oil. The

oil/

gas
mix must meet the vehicle require­ments. See oil manufacturer re-com­mendations on the container.

..,

CAUTION: Never use outboard

...

or straight mineral oils.

Fuel Mixture Ratio

The importance of using the correct
fuel mixture cannot be overstressed.

An incorrect fuel ratio results in serious

engine damage. Recommended fuel

ratio is 50/1. (40/1 during brake in
period).

SI Measure

500 mL oil to 25 liters = 50/1.

Imperial Measure

1 can 16

02

oil to 5 Imp. gals = 50/1.

or

1 can 500 mL oil to 5 1/2 Imp. gals

50/1.

U.S.

Measure

1 can 12

02

oil to 5 U.S. gals = 50/1.

O

NOTE: To facilitate fuel mixing oil

should be kept at room tempera-

ture.

Fuel Mixing Procedure

To mix the gasoline and oil always use
a separate clean container. Never mix
directly in your snowmobile tank. For
best results, acquire

two

containers,
either plastic or metal. Draw from one
until empty then use the second one.

A WARNING: Gasoline is flamma-

.",.

ble and explosive under certain

conditions. Always perform

pro-

cedures in a well ventilated area. Do
not smoke or allow open flames or
sparksin the vicinity. If gasolinefumes
are noticed while driving, the cause
should be determined and corrected

without delay. Never add fuel while the

engine is running. Avoid skin contact

with fuel at below freezing tempera-

ture.

1. Pour approximately one gallon of
gasoline into a clean container.

2. Add the full amount of oil.

9

3. Replace the container cap and
shake the container thoroughly.

4. Add the remainder of the gasoline.

5. Once again thoroughly agitate the

container. Then using a funnel with
a fine mesh screen to prevent the
entry of water and foreign particles,
transfer mixture from container into
the snowmobile tank.

A WARNING: To prevent fuel spill-

....

age in the engine compartment, a

funnel must always be used when fill-

ing the gas tank.

a

NOTE: When using pre-mixed

fuel, always shake the container
thoroughly as the oil hasa tendency to
settle.

AWARNING:

Never

'top

up' the

....

gas tank before placing vehicle
in a warm area.

At

certain tempera-

tures, gasoline

will

expand and

overflow.

PRE-START CHECK

Check Points

• Activate the throttle control lever
several times to check that it oper­ates easily and smoothly. The throt­tle control lever must return to idle
position when released.

• Check that the skis and the track are

not frozen to the ground or snow
surface and that the steering oper­ates freely.

• Activate the brake control lever and
make sure the brake fully applies be­fore the brake control lever touches

the handlebar grip.

• Check coolant level. Liquid should
be 2.5 em (1") below filler neck. If

additional coolant is necessary

1 al-

ways use a 50/50 (50 parts of water

for

50 parts of antifreeze) solution.

When entire system has to be re­filled use a solution of 3 parts of

anti-freeze for 2 parts of water. See

cooling system in storage .

A WARNING: Before removing

....

the cap always the pressure by

placing a rag on the cap and by par-

tially unscrewing

it (first step). If this

is disregarded loss of fluid and
possibility of severe burns could oc­cur.

• Check fuel level.

• Verify that the path ahead of the ve­hicle is clear of bystanders and ob-

stacles.

A WARNING: Only startyoursnow-

....

mobile once all components are

checked and functioning properly.
