Observe the following precautions:
• Throttle mechanism should be
checked for free movement before
starting engine.
• Engine should 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 the engine at high R,P.M,
when the track of the vehicle is
raised
off the ground.
• It can be dangerous to run engine
with the cab open or removed,
• Gasoline is flammable and explosive
under certain conditions. Always
perform procedures in awell ventila-
ted area. Do not smoke or allow
open flames or sparks in the vicinity,
If gasoline fumes are noticed while
driving, the cause should be deter-
mined 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 your 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 surfa-
ces. On such surfaces abnormal and
excessive wear of critical parts is
inevitable.
• Only perform procedures asdetailed
in this manual. It is recommended
that dealer assistance beperiodically
obtained on other components /
systems
not covered in this manual.
Unless otherwise specified, engine
should be turned OFF for all lubri-
cation and maintenance procedures.
•Installation of other than
"stock"
equipment, including ski-spreaders,
bumpers, pack racks, etc.. could
severely affect the stability and
safety of your vehicle. Avoid adding
on accessories that alter the basic
vehicle configuration.
• The snowmobile engine can be
stopped by activating the emergen-
cy cut-out or tether switches, or
turning
off the key.
• On
T'NT equipped with free air en-
gine since the engine cooling is in
effect only when the vehicle is in
motion, it is recommended that you
do not allow the engine to idle for
more brief periods. Prolonged idling
and low speed operation may cause
engine damage.
Please read and understand all other
warnings contained elsewhere in this

sible damage to breakable items when
travelling over rough or bumpy terrain.
On all models except Elan models, un-
screw fuel tank cap and
withdraw dip-
stick to check fuel level. On Elan mod-
els, the tank is translucent and fuel
level can be checked by opening cab
and glancing at tank.
•WARNING: Never use a lite
match or open flame to check
fuel level.
With Bombardier-Rotax snowmobile
engines, a break-in period is required
before running the vehicle at full
throttle. Engine's manufacturer re-
commendation is 10 to 15 operating
hours. During this period, a richer mix-
ture is needed (i.e. 40 parts of gas for
1part of 50 / 1 Bombardier oil). Maxi-
mum throttle should not exceed %,
however, brief full acceleration and
speed variations contribute to a good
break-in. Continued wide open throttle
accelerations, prolonged cruising
speeds, and luggin are detrimental
during the break-in period.
As with any precision piece of mechan-
ical equipment, we suggest that after
the first 10 hours of operation or 30
days after the purchase, whichever
comes first, that your vehicle be
checke.d by your dealer. This inspec-
tion will give you the opportunity to
discuss the unanswered questions you
may have encountered during the first
hours of operation. Remember that it
is easier to remedy at this time than to
allow the snowmobile to operate until
a possible failure occurs.
The 10 hours inspection is at the ex-
penseof the vehicleowner.
7

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.
The correct gasoline is regular gasoline
(not less than 92 octane), available
from all service stations.
_ CAUTION: Never experiment
.". with different fuel or fuel ratios.
Never use low lead or non leadedgaso-
line, naphtha, methanol or similar
products.
Use concentrated Bombardier snow-
mobile oil available from your dealer.
This type of oil has specially formulated
oil bases to meet the lubrication re-
quirements of the Bombardier-Rotax
ermine.
If lombardier snowmobile oil is un-
ava.lable substitute with ahigh-quality
2cycle snowmobile oil. The oil/gas
mix must meet the vehicle require-
ments. See oil manufacturer recom-
mendations on container.
_CAUTION: Never use outboard
.". or straight mineraloils.
The importance of using the correct
fuel.mixture cannot be overstressed. An
incorrect fuel ratio results in serious en-
gine damage. Recommended fuel ratio
is 50
/1.
5 gallons of regular gasoline plus 1
can
of 50/1concentrated Bombardier
snowmobile oil
== correct fuel mixture.
ONOTE: To facilitate fuel mixing,
oil should be kept at room tempe-
rature.
8
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, ei-
ther plastic or metal. Draw from one
until empty then use the second one.
•
WARNING: Gasoline is flamma-
ble 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 de-
termined and corrected without delay.
Never add fuel while engine is running.
Avoid skin contact with fuel at below
freezing temperatures.
1. Pour approximately one gallon of
gasoline into aclean container.
2. Add the full amount of oil.

3. Replace 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.
aNOTE: When using pre-mixed
fuel, always shake the container
thoroughly as the oil has a tendency
to settle.
•
WARNiNG: Never 'top up' gas
tank before placing vehicle in a
warm area.
At certain temperatures,
gasoline will expand and overflow.
(IW. Check fuel level.
(IW Check that the skis and the track are
not frozen to the ground or
snow
surface and that the steering oper-
ates freely.
@; Activate the throttle control lever
several times to check
that it oper-
ates easily and
smoothly. The
throttle control lever must return to
idle position when released.
(fl; Activate the brake control lever and
make sure the brake fully applies be-
fore the brake control lever touches
the handlebar grip.
.1& Verify that the path ahead of the ve-
hicle is clear of bystanders and
obstacles.

.". solution to enter battery. It will
destroy the chemical properties of the
electrolyte.
After reconnecting battery coat bat-
tery terminals and connectors with pe-
troleum jelly to prevent corrosion.
Check that battery is well secured and
that battery overflow tube is not bloc-
ked or kinked.
+WARNING: Overflow tube must
be free and open. A kinked or
bent tube will restrict ventilation and
create gas accumulation
that could
result in an explosion. Avoid skin con-
tact with electrolyte.
Visually inspect suspension springs.
Replace any weak or broken spring. If
vehicle is equipped with a slide sus-
pension, inspect shoe condition and re-
place as necessary.
ONOTE: During normal driving,
snow will act as a lubricant and
coolant for the slider shoes. Extensive
riding on ice or sanded snow, (not to
mention dirt. asphalt, etc. never re-
commended) will create excessive heat
build-up and cause premature slider
shoe wear.

same on both sides. Misalignment can
cause excessive wear of track edges
and sprocket teeth.
