DRIVING HINTS

Driver confidence and capability are thekeys to full enjoyment of your new Ski­Doo snowmobile. For your first few runs,select a large. clear, fiat area then prac­tice the uses and responses of the vari­ous controls and get the feel and balanceof your vehicle.

When first using throttle and brake, mostbeginners press and release the leverstoo quickly, causing a corresponding"jerking" of the machine. Instead,squeeze the levers firmly and smoothlyso acceleration and braking are even.When braking, remember that snow­mobiles have a broad, flat track in con­tinuous contact with the ground, so thatthe vehicle immediately starts to slow ofits own accord as soon as the throttlelever is released. For most circum­stances, this natural slowing action plusa gentle pressure on the brake are morethan sufficient to stop the vehicle.

Driving PositionsThere are 3 main driving positions on asnowmobile - (1) Standing, (2) Kneel­ing, and (3) Sitting.Each presents certain advantages de­pending on the nature of the terrain, thesnow conditions, speed of the vehicle,the turns you desire or the personal pref­erence of the driver.(1) Standing - a position often adopt­ed by beginners, allows for better weight

distribution and permits you to respondto the movement of your snowmobilewith surer control. With this position,however, always keep your knees slightlyflexed to absorb surface shocks.

The position is undoubtedly the best forsteep hills, climbing or going down, ashort stretch of very bumpy trail or whenmanoeuvering in deep snow.

(2) Kn~elil'lg - crossing a steep slope,for example, from side to side, you willfind the kneeling position a definite ad­vantage. Place one foot on the footboard(on the high side of the hill), the oppositeknee on the seat, then lean into the hill.If leaning left, your left foot should be onthe footboard, your right knee on theseat, and vice-versa.

WARNING: Side hills and steep slopesare not recommended for a beginner.An alternate recommended kneeling po­sition and one that is frequently used, isto place both knees on the seat, with onefoot on each side, loosely pressingagainst the seat. This position is usefulshould you encounter bumpy trails wheresitting is uncomfortable.

(3) SiUing - for all normal driving, themost comfortable position is the sittingposition. Toes should be held loosely inthe stirrups, body about midway back onthe seat and body weight distributedevenly between the seat and footboards.

Quick TipsWhen necessary to turn your snowmobilearound by hand, always lift back endrather than front.If you have to turn your vehicle around byhand in deep or loosely packed snow,first press down firmly on the tips of yourskis. This will raise the trailing edges, sothat they do not dig in while vehicle isbeing turned.

TurningIn turning. you will quickly find that oftenyou cannot rely on the handlebars aloneto turn within the circle you desire. Part

of the fun of snowmobiling is that eachturn depends on 4 factors - the radiusof the turn, vehicle speed, snow condi­tions and the weight on the skis.To make those tight, fast turns that arethe mark of the experienced driver, youmust learn to use the weight or positionof your body, shifting to left or right asthe turn demands and keeping your cen­tre of gravity as low as possible.In soft or lightly packed snow, the theoryof weight shifting is that by leaning thebody toward the inner side of the turnyou increase the pressure on that edgeof the track and correspondingly lightenthe other edge. In effect, you create abank of snow under the lighter edge, sothat the vehicle is banked when turning.On hard packed snow, leaning in towardthe turn and at the same time keepingyour centre of gravity as low as possible,counterbalances the natural tendency ofany vehicle to tilt when turning.Also, moving your body weight towardthe front of the vehicle, particularly, inhard-packed snow, adds pressure to theskis and ski runners so that they bitemore deeply into the snow surface.

IMPORTANT: Thoroughly know yourvehicle and how to drive it before at­tempting difficult or rapid manoeuvres.

Surface ConditionsDeep Snow - Your new Ski-Doo snow-

mobile is designed to negotiate almostany snow surface, including deep ornewly-fallen snow. Two things are im­portant however, - (1) don't overloadyour machine (Le. travel alone, not withpassengers) and (2) maintain a reason­able forward speed at all times. Don'taccelerate beyond the track's ability tocope with the surface underneath, anddon't stop.Use the standing position recommendedearlier and if your vehicle continues tomake reasonable headway, respondingto light changes in acceleration, you aresafe enough to explore new areas. If not,

";,...- 1\'

" \~II

turn in as wide an arc as possible andlook for firmer trails.

Icy Surface - Ice or extremely hard­packed snow can be difficult to negotiateas both skis and track do not have muchtraction. Best advice is to slow down andavoid rapid acceleration or braking.

TipsThree good tips to follow to minimizeyour chances of being stranded are (1)stay on known trails and familiar terrain,(2) travel with friends or in company withother snowmobiles, and (3) do regularlubrication and maintenance faithfully.

DO'S

• Register your Ski-Doo snowmobile atyour nearest Licensing Bureau, whereState or Provincial Laws require it, andaffix Registration Plate to the vehicle.Carry your registration certificate withyou. It provides proof of ownership in theevent that the vehicle becomes lost orstolen.• Obtain your State or Provincial bookleton snowmobiling. It gives valuable in­formation on the neighbouring snow­mobile trails and the laws governingsnowmobiling in your particular area.• Always carry emergency materials andsupplies. Your local Ski-Doo dealer hasa Safety Centre prepared specially foryou.

• Let every riding member of your familyread the entire Owner's Manual. Theknowledge and confidence gained willreduce the risk element.• Observe all posted snowmobile signs.Not all private landowners allow snow­mobiling on their property. You can havejust as much fun, even more so, by trav­eling elsewhere.• Before you start out, check to be surethat you and each member of your partyare equipped with sufficient warm cloth­ing and safety helmets.• When snowmobiling with others, limityour actions to the experience of themain body. Show the inexperience driverhow to properly handle a snowmobile.

S

• Use the 'buddy" system. Always travelwith at least one other snowmobile, es­pecially in unfamiliar terrain or on trailrides. Even in snowmobiling, a pair beatsone of a kind.

• If you are planning to explore newareas, leave word of your approximatewhereabouts and estimated time otre­turn with someone. Remember, a snow­mobile can often travel farther in 15 min­utes than you can walk in a day.

• Always make a full stop, then lookcarefully in both directions before cross­ing roads. When traveling in pairs or ina group, have one member direct theothers across, singly.

• Use a rigid hitch or tow-bar when pull­ing any sled or trailer behind your Ski­Doo snowmobile. Rigid hitches preventtailgate collision when going downhill oron sudden stops.

• Be extremely careful when givingchildren a ride. Go more slowly andcheck frequently. Small children, are farsafer in a Ski-Boosa* sled than on theseat of your snowmobile.

• When trailering your Ski-Doo snow­mobile, secure it solidly at both ends,protect it with a bright cover (Ski-Doo"cover) then check that trailer hitch andsafety chain are secure and that brake,flashers and parking lights are all inworking order.

'Trademark of Bombardier Limited

DONT'S

• Don't cut across in front of the line oftravel of another snowmobile. Don't tail­gate; collision, or the threat of it, is se­rious with any moving vehicle.

• Don't risk injury or damage to yourmachine with needless and foolish stunt­ing. Don't "jump" your snowmobile. Thispart of snowmobiling should be left tothe professional "stunt" men.

• NEVER ride on railway tracks. Thesounds of your moving vehicle drown outnoise of approaching trains. Your vehiclemay also become caught in track junc­tions. In many States and Provincessnowmobiling on railway tracks consti­tutes an infraction of the law.

• Never cut through fences or attemptto run over them. Give a wide berth totelephone poles. Hidden guy wires, un­seen from a distance, can cause seri­ous accidents.

• Don't lend your snowmobile to inex­perienced or under-age drivers. In manycases it is th~ vehicle owner and not therider that is responsible for mishaps.Check State or Provincial minimum agelimits for drivers.

• Unless you are certain. of a fuelingstop, never travel further than 112 of thefuel remaining in your tank. Even then,leave yourself a safety margin. Remem­ber that a snowmobile does not neces­sarily travel the same distance each time

on the same amount of fuel. A lot de­pends on speed, the snow conditions ofthe trail and the adjustment of the car­buretor.

• Don't drive your snowmobile In thevicinity of skiers and keep off ski trails.Always respect the rights of those whoenjoy winter in another way.

• Don't smoke while refueling or whilechecking fuel level. Even mixed fuelgives off dangerous fumes.

• "If you drink don't snowmobile! If yousnowmobile, don't drink!" Rememberalcohol and gasoline don't mix.

• Don't overload your snowmobile. ASki-Boose sled or other trailer carries farmore than your snowmobile can, with­out noticeable loss of efficiency or man­oeuverability.

• Don't cross a river or lake without firstbeing positive that the thickness of theice is sufficient to support both you andyour vehicle. Your life may depend on it.If at all in doubt, take an alternate route.

• Don't ride on public streets, roads orhighways. The single largest cause ofaccidents have occured when snow­mobiles and automobiles mix.

• Don't leave your keys in the ignitionswitch. It prevents an invitation to thievesand a danger to children.

Fuel Mixing ProcedureTo mix the gasoline and oil always use aseparate clean container. Never mixdirectly in your snowmobile tank.

WARNING: Gasoline is flammable andexplosive under certain conditions. Al­ways stop the engine and do not smokeor allow open flames or sparks near thevehicle when refueling. " gasoline fu­mes are noticed while driving, thecause should be determined and co,­rected without delay.Note: For best results, acquire two con­tainers either plastic or metal.

Draw from one until empty then use thesecond one. Meanwhile, refill the first assoon as convenient.1. Pour the full amount of Ski-Doo oilrequired for the total mixture into thecontainer.2. Add approximately half the amount ofgasoline to be mixed.3. Shake the container thoroughly.4. Add the remainder of the gasoline.5. Once again thoroughly agitate thecontainer.6. Using a funnel with a fine meshscreen to prevent the entry of water and

foreign particles, transfer the mixturefrom the container into the Ski-Doosnowmobile gas tank.

CAUTION: Avoid fuel splashing or spill­ing onto adjacent drive belt.

Fuel Saving TipsWhile waiting for companions to catchup, or when stopping to rest on the trail,turn your ignition OFF. Not only do yousave fuel, but you lessen the chance ofspark plug fouling. Besides, a warmed­up Ski-Doo snowmobile engine is excep­tionally easy to start.

13

PRE-START CHECK

Fuel Tank QuantityCheck that there is sufficient fuel in thetank for your trip. A good habltjo acquireis to refill the tank before starting outeach day.Since mixed fuel has a tendency to settleovernight, agitate the fuel in the tank bystanding on the tootboardssnd rockingthe vehicle from side to side.

Track (Daily, before first run)

Under certain climatic conditions, thetrack of a snowmobile left outdoors over­night may freeze to the ground or snowsurface. Always make sure that the trackis free before attempting to atart the ve­hicle. (This procedure will ellrninate un­necessary drive belt wear).

Steering OperationCheck operation of steering mechanismby rotating the handlebars several timesfrom side to side. If roughness or bindingis felt, check for ice or snow that may beblocking the mechanism.

IN CASE OF EMERGENCYEmergency situations are accepted haz­ards with any moving vehicle. A hiddenrock or stump on the trail, a blown fuse orburn light bulb while driving at night, anempty fuel tank while mites from any­where, can all cause varying degrees ofinconvenience.

Unlike an automobile, which has a dis­tinct in that service stationsare usually within walking distance,snowmobiles are specifically designedto travel OFF the highways. When theunexpected happens, the driver often hasonly his own ingenuity and that of hiscompanions to return home safely.

Fortunately, 9 out of 10 difficulties en­countered on the trail can be fixed on thespot. However, you must carry at least aminimum assortment of Tools and SpareParts to enable you to effect minor re­pairs.

EmergencyIn addition to those tools which the manu­facturer provides, you should carry thefollowing:

ToolsGeneral Purpose Pliers - AdjustableWrench (3/4" opening) - Flashlight - Fuelde-jcer.

Spare PartsSpark Plug - Drive belt - Headlampand Taillight bulbs - Light Fuse (Elec­tric model only) - Throttle Gable andHousing - Starting or towing rope.

IMPORTANT: Always carry spare plugsand drive belt. Check condition of sparkplug frequently (See Fig. 11) and look forsigns of a fouled or defective plug. Nextto "out of fuel" worn spark plug cancause trouble on the trail.

Assisting StrandedVehiclesIt is an unwritten law of snowmobilingthat you go to the aid of any snowmobilestranded in the field. Should another ve­hicle have to be towed:1. Remove the drive belt. (See Fig. 1).2. Tie both skis to your vehicle.3. Taking the driver with you as a pas­senger, tow the vehicle back slowly.

For short distances, or if tow rope is un­available, you may push both vehicle anddriver.

TROUBLE SHOOTING GUIDE

What To Do

Check the tank level and fill up with correct gas-oil mixture. (Refer to Fuel Mixing,Page 12). Check for possible clogging of fuel line, item 5,

Check for fouled or defective spark plug. (See Fig. 11). Disconnect spark plugwire, unscrew plug and remove from cylinder head, Reconnect wire and groundexposed plug to engine head, being careful to hold away from spark plug hole.Follow engine starting procedure and check for spark. If no sparks appear,replace spark plug, If trouble persists, check item 3.

Disconnect spark plug wire from plug, unscrew the spark plug cap then holdwire about Va" from the cylinder head. Follow engine starting procedure and ifno sparks appear, it means a faulty ignition system. Do not attempt to repair.Contact your dealer.

Turn choke knob to OFF, wait 60 seconds or more then depress throttle leverfully and try to start engine. Releasethrottle lever immediately after enginestarts.

Remove and clean the fuel filter. Change filter cartridge if necessary. Check thecleanliness of the fuel tank. Clean tank if necessary. (See Fuel Tank, Page 27).

Screw in the idle speed mixture adjusting screw and turn it back % of a turn.Make final adjustment with engine running and warmed up. (See Fig. 15).

First make primary adjustmentson carburetor. (See Maintenance Section, Page20).If carburetor is still faulty, contact your dealer for repair.

Drain the fuel tank and refill with the correct gas/oil mixture. (Refer to FuelMixing, Page 12).

Breaker points may be worn or out of adjustment. Contact your dealer.

Running with a lean fuel mixture may produce excessive engine wear reSUltingin poor engine compression. If this occurs, contact your dealer at once.

In the case of a seized engine, contact your dealer. Seizure is a direct result ofpoor lubrication.
