DRIVING HINTS
Driver confidence and capability are the
keys to full enjoyment of your new Ski-
Doo snowmobile. For your first few runs,
select a large. clear, fiat area then prac-
tice the uses and responses of the vari-
ous controls and get the feel and balance
of your vehicle.
When first using throttle and brake, most
beginners press and release the levers
too quickly, causing a corresponding
"jerking" of the machine. Instead,
squeeze the levers firmly and smoothly
so acceleration and braking are even.
When braking, remember that snow-
mobiles have a broad, flat track in con-
tinuous contact with the ground, so that
the vehicle immediately starts to slow of
its own accord as soon as the throttle
lever is released. For most circum-
stances, this natural slowing action plus
a gentle pressure on the brake are more
than sufficient to stop the vehicle.
Driving Positions
There are 3 main driving positions on a
snowmobile - (1) Standing, (2) Kneel-
ing, and (3) Sitting.
Each presents certain advantages de-
pending on the nature of the terrain, the
snow conditions, speed of the vehicle,
the turns you desire or the personal pref-
erence of the driver.
(1) Standing -a position often adopt-
ed by beginners, allows for better weight
6
distribution and permits you to respond
to the movement of your snowmobile
with surer control. With this position,
however,always keep your knees slightly
flexed to absorb surface shocks.
The position is undoubtedly the best for
steep hills, climbing or going down, a
short stretch of very bumpy trail or when
manoeuvering in deep snow.
(2) Kn~elil'lg -crossing a steep slope,
for example, from side to side, you will
find the kneeling position a definite ad-
vantage. Place one foot on the footboard
(on the high side of the hill), the opposite
knee on the seat, then lean into the hill.
If leaning left, your left foot should be on
the footboard, your right knee on the
seat,and vice-versa.
WARNING: Side hills and steep slopes
are not recommended for a beginner.
An alternate recommended kneeling po-
sition and one that is frequently used, is
to place both knees on the seat,with one
foot on each side, loosely pressing
against the seat. This position is useful
should you encounter bumpy trails where
sitting is uncomfortable.
(3) SiUing - for all normal driving, the
most comfortable position is the sitting
position. Toes should be held loosely in
the stirrups, body about midway back on
the seat and body weight distributed
evenly between the seat and footboards.
Quick Tips
Whennecessary to turn your snowmobile
around by hand, always lift back end
rather than front.
If you have to turn your vehicle around by
hand in deep or loosely packed snow,
first press down firmly on the tips of your
skis. This will raise the trailing edges, so
that they do not dig in while vehicle is
being turned.
Turning
In turning. you will quickly find that often
you cannot rely on the handlebars alone
to turn within the circle you desire. Part

of the fun of snowmobiling is that each
turn depends on 4 factors - the radius
of the turn, vehicle speed, snow condi-
tions and the weight on the skis.
To make those tight, fast turns that are
the mark of the experienced driver, you
must learn to use the weight or position
of your body, shifting to left or right as
the turn demands and keeping your cen-
tre of gravity as low as possible.
In soft or lightly packed snow, the theory
of weight shifting is that by leaning the
body toward the inner side of the turn
you increase the pressure on that edge
of the track and correspondingly lighten
the other edge. In effect, you create a
bank of snow under the lighter edge, so
that the vehicle is banked when turning.
On hard packed snow, leaning in toward
the turn and at the same time keeping
your centre of gravity as low as possible,
counterbalances the natural tendency of
any vehicle to tilt when turning.
Also, moving your body weight toward
the front of the vehicle, particularly, in
hard-packed snow, adds pressure to the
skis and ski runners so that they bite
more deeply into the snow surface.
IMPORTANT: Thoroughly know your
vehicle and how to drive it before at-
tempting difficult or rapid manoeuvres.
Surface Conditions
Deep Snow -Your new Ski-Doo snow-
mobile is designed to negotiate almost
any snow surface, including deep or
newly-fallen snow. Two things are im-
portant however, - (1) don't overload
your machine (Le. travel alone, not with
passengers) and (2) maintain a reason-
able forward speed at all times. Don't
accelerate beyond the track's ability to
cope with the surface underneath, and
don't stop.
Usethe standing position recommended
earlier and if your vehicle continues to
make reasonable headway, responding
to light changes in acceleration, you are
safe enough to explore new areas. If not,
"
;,...
- 1\'
" \~II
turn in as wide an arc as possible and
look for firmer trails.
Icy Surface -Ice or extremely hard-
packed snow can be difficult to negotiate
as both skis and track do not have much
traction. Bestadvice is to slow down and
avoid rapid acceleration or braking.
Tips
Three good tips to follow to minimize
your chances of being stranded are (1)
stay on known trails and familiar terrain,
(2) travel with friends or in company with
other snowmobiles, and (3) do regular
lubrication and maintenance faithfully.

DO'S
• Register your Ski-Doo snowmobile at
your nearest Licensing Bureau, where
State or Provincial Laws require it, and
affix Registration Plate to the vehicle.
Carry your registration certificate with
you. It provides proof of ownership in the
event that the vehicle becomes lost or
stolen.
• Obtain your Stateor Provincial booklet
on snowmobiling. It gives valuable in-
formation on the neighbouring snow-
mobile trails and the laws governing
snowmobiling in your particular area.
• Always carry emergency materials and
supplies. Your local Ski-Doo dealer has
a Safety Centre prepared specially for
you.
• Let every riding member of your family
read the entire Owner's Manual. The
knowledge and confidence gained will
reduce the risk element.
• Observe all posted snowmobile signs.
Not all private landowners allow snow-
mobiling on their property. You can have
just as much fun, even more so, by trav-
eling elsewhere.
• Before you start out, check to be sure
that you and each member of your party
are equipped with sufficient warm cloth-
ing and safety helmets.
• When snowmobiling with others, limit
your actions to the experience of
the
main body. Showthe inexperience driver
how to properly handle a snowmobile.
S
• Use the 'buddy" system.Always travel
with at least one other snowmobile, es-
pecially in unfamiliar terrain or on trail
rides. Evenin snowmobiling, a pair beats
one of a kind.
• If you are planning to explore new
areas, leave word of your approximate
whereabouts and estimated time
otre-
turn with someone. Remember, a snow-
mobile can often travel farther in 15 min-
utes than you can walk in a day.
• Always make a full stop, then look
carefully in both directions before cross-
ing roads. When traveling in pairs or in
a group, have one member direct the
others across, singly.
• Use a rigid hitch or tow-bar when pull-
ing any sled or trailer behind your Ski-
Doo snowmobile. Rigid hitches prevent
tailgate collision when going downhill or
on sudden stops.
•Be extremely careful when
giving
children a ride. Go more slowly and
check frequently. Small children, are far
safer in a Ski-Boosa* sled than on the
seat of your snowmobile.
• When trailering your Ski-Doo snow-
mobile, secure it solidly at both ends,
protect it with a bright cover (Ski-Doo"
cover) then check that trailer hitch and
safety chain are secure and that brake,
flashers and parking lights are all in
working order.
'Trademark of Bombardier Limited

DONT'S
• Don't cut across in front of the line of
travel of another snowmobile. Don't tail-
gate; collision, or the threat of it, is se-
rious with any moving vehicle.
• Don't risk injury or damage to your
machine with needlessand foolish stunt-
ing. Don't "jump" your snowmobile. This
part of snowmobiling should be left to
the professional "stunt" men.
•
NEVER ride on railway tracks. The
sounds of your movingvehicle drown out
noise of approaching trains. Yourvehicle
may also become caught in track junc-
tions. In many States and Provinces
snowmobiling on railway tracks consti-
tutesan infraction of the law.
• Never cut through fences or attempt
to run over them. Give a wide berth to
telephone poles. Hidden guy wires, un-
seen from a distance, can cause seri-
ous accidents.
• Don't lend your snowmobile to inex-
perienced or under-age drivers. In many
cases it is
th~ vehicle owner and not the
rider that is responsible for mishaps.
Check State or Provincial minimum age
limits for drivers.
• Unless you are certain. of a fueling
stop, never travel further than
112 of the
fuel remaining in your tank.
Even then,
leave yourself a safety margin. Remem-
ber that a snowmobile does not neces-
sarilytravel the same distance each time
on the same amount of fuel. A lot de-
pends on speed, the snow conditions of
the trail and the adjustment of the car-
buretor.
• Don't drive your snowmobile In the
vicinity of skiers and keep off ski trails.
Always respect the rights of those who
enjoy winter in another way.
• Don't smoke while refueling or while
checking fuel level. Even mixed fuel
gives off dangerous fumes.
• "If you drink don't snowmobile! If you
snowmobile, don't drink!" Remember
alcohol and gasoline don't mix.
• Don't overload your snowmobile. A
Ski-Boose sled or other trailer carries far
more than your snowmobile can, with-
out noticeable loss of efficiency or man-
oeuverability.
• Don't cross a river or lake without first
being positive that the thickness of the
ice is sufficient to support both you and
your vehicle. Your life may depend on it.
If at all in doubt, take an alternate route.
• Don't ride on public streets, roads or
highways. The single largest cause of
accidents have occured when snow-
mobiles and automobiles mix.
• Don't leave your keys in the ignition
switch. It prevents an invitation to thieves
and a danger to children. 9

Fuel Mixing Procedure
To mix the gasoline and oil always use a
separate clean container. Never mix
directly in your snowmobile tank.
WARNING: Gasoline
is flammable and
explosive under certain conditions. Al-
waysstop the engine and do
not smoke
or allowopen flames or sparks near the
vehicle when refueling. "gasoline fu-
mes are noticed while driving, the
cause should be determined and co,-
rected without delay.
Note: For best results, acquire two con-
tainers either plastic or metal.
Draw from one until empty then use the
second one. Meanwhile, refill the first as
soon as convenient.
1. Pour the full amount of Ski-Doo oil
required for the total mixture into the
container.

save fuel, but you lessen the chance of
spark plug fouling. Besides, a warmed-
up Ski-Doo snowmobile engine is excep-
tionally easy to start.
