BREAK-IN PERIOD
With Bombardier-Rotax snowmobile
engines, a bread-in period is required
before running the vehicle at full
throt-
tle. Engine manufacturer recommen-
dation is 10 to 15operating hours. Dur-
ing this period, a richer mixture is
needed (i.e. 40 parts of gas for 1part of
50/1 Bombardier oil). Maximum throt-
tle should not exceed
3/4, however,
brief full acceleration and speed varia-
tions contribute to a good break-in.
Continued wide open throttle accelera-
tions, prolonged cruising speeds, and
lugging are detrimental during the
break-in period.
10-Hour Inspection
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 check-
ed by your dealer. This inspection 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 hour 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
Use regular leaded gasoline available
from all service stations.
_
CAUTION: Never experiment
.. with different fuel or fuel ratios.
Never use naphtha, methanol or similar
product.
Recommended 'Oil
Use concentrated Bombardier snow-
mobile oil available from your dealer.
This type of oil has speciallyformulated
oil bases to meet the lubrication re-
quirements of the Bombardier-Rotax
engine.
If Bombardier snowmobile oil is un-
available, 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 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.
S.1. MEASURE
500 mL oil to 25 liters = 50/1
IMPERIAL MEASURE
1can 16 oz oil to 5imp. gals= 50/1
or
1can 500 mL oil to 51/2 imp. gals= 50/1
U.S. MEASURE
1can 12 oz oil to 5U.S. gals= 50/1
ONOTE: To facilitate fuel mixing oil
should be kept at room tempera-
ture.
8
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, ei-
ther plastic or metal. Draw from one
until empty then usethe second one.
...... WARNING: Gasoline is flamma-
..... ble and explosive under certain
conditions. Always performprocedures
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 a clean 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.
ONOTE: 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 the vehicle in
a warm area. At certain temperatures,
gasolinewill expand and overflow.

(W7) Drive Belt
Inspect belt for cracks. fraying or ab-
normal wear (uneven wear, wear on
one side, etc.) If abnormal wear is
noted, probable cause is pulley mis-
alignment. Contact your dealer. Check
drive belt width, it should not be less
than 30 mm
(1 3/16") wide.
ONOTE: When installing a new
drive belt, a break-in period of
15-25 km (10-15 miles) is strongly re-
commended.
(WS) Steering Mechanism
Inspect steering mechanism for tight-
ness of components (steering arm, ball
joint, etc.I. If necessary, replace or re-
tighten. Check condition of ski and ski
runner. Replace if worn.
(W9) Drive Chain Tension
Run vehicle forward so that true free-
play can be taken. Check tension then
turn driven pulley 1/2 turn counter-
clockwise and recheck. Starting from
maximum reading, adjust chain ten-
sion to 6 mm
(1/4") free-play. Remove
capscrew locking chain tensioner in
place. (Tensioner is located at bottom
left of gearbox).
,Chain tensioner
Rotate the tensioner as required to ob-
tain correct chain tension.
Replace capscrew to lock chain ten-
sicner jn place.

(W10) Drive Pulley
Inspect the Duralon bushing condition
by checking the free-play of the sliding
half pulley. This is achieved by restrain-
ing the inner half and checking if the
sliding half moves in the direction of
the arrows more than 3mm
(1/8/'). If
so contact your dealer.

(M1) Brake
The brake mechanism is self-adjusting,
therefore, periodic adjustment is not
required. However/ the brake mecha-
nism can be checked by depressing
brake control lever. Brake should apply
fully when lever is 13 mm
(1/2") ap-
prox. from handlebar grip. If it does
not, do not tamper
with the brake,
contact your servicing dealer. Check
the stop light to see if it functions. If
necessary, readjust switch position.
.... WARNING: Brake pucks less
..... than 5 mm (3/16") thick must be
replaced. Replacement must be per-
formed by an authorized Bombardier
dealer. Always check the stop light to
see if it functions.

bar. To align:
Remove steering padding.
Remove bolt securing handlebar to
steering column.
Remove handlebar to expose splined
end of steering column.

Reposition handlebar on so that
it is perpendicular with Install and
tighten bolt to 40-47
N.m (30-35ft-lbs).
ONOTE: If correct spline alignment
is unobtainable at handlebar,
move lower steering bracket (located
on top of gearbox) to obtain proper lo-
cation. Lower bracket holes
are slotted.
(M3) Engine Head Nuts
IMPORTANT: The engine head nut tor-
que should be checked after the first 5
hours of operation.
With engine cold, check that engine
head nuts are
tight and equally torqued
to 20 N.m (15 ft-lbs).
(M4) Engine Mount nuts

ness. Retighten if necessary.
(M5) Muffler Attachment
The- engine / muffler attaching parts
are vital toward efficient muffler func-
tion. Check all attachments. Replace
springs and / or tighten if necessary.
(MS) Fan Belt
Inspect belt for cracks, uneven wear,
etc. Check fan belt tension, 6 mm l;4
")
free-play should exist when deflection
iscorrect.
If belt seems damaged or if tension is
incorrect, contact your dealer immedi-
