Know the terrain where you ride. Ride cau-tiously in unfamiliar areas.Stay alert for holes, rocks, or roots in the ter-rain, and other hidden hazards which maycause the ATV to upset.

WARNING

POTENTIAL HAZARD Failure to use extra care when operatingthis ATV on unfamiliar terrain. WHAT CAN HAPPEN You can come upon hidden rocks,bumps, or holes, without enough time toreact.Could result in the ATV overturning orgoing out of control.

Select a large, flat area off-road to become fa-miliar with your ATV. Make sure that this areais free of obstacles and other riders. Youshould practice control of the throttle, brakes,shifting procedures, and turning techniques inthis area before trying more difficult terrain. Al-ways avoid riding on paved surfaces: the ATVis designed for off-road use only, and han-dling maneuvers are more difficult to performon pavement.

Set the parking brake and follow the instruc-tion on page 6-1 to start the engine. Once ithas warmed up you are ready to begin ridingyour ATV.

TURNING YOUR ATV To achieve maximum traction while riding off-road, the two rear wheels are mounted solidlyon one axle and turn together at the samespeed. Therefore, unless the wheel on the in-side of the turn is allowed to slip or lose sometraction, the ATV will resist turning. A specialturning technique must be used to allow theATV to make turns quickly and easily. It is es-sential that this skill be learned first at lowspeed.

CROSSING A SLOPE Traversing a sloping surface on your ATV re-quires you to properly position your weight tomaintain proper balance. Be sure that youhave learned the basic riding skills on flatground before attempting to cross a slopingsurface. Avoid slopes with slippery surfacesor rough terrain that may upset your balance.

As you travel across a slope, lean your bodyin the uphill direction. It may be necessary tocorrect the steering when riding on loose sur-faces by pointing the front wheels slightly up-hill. When riding on slopes be sure not tomake sharp turns either up or down hill.

Spark plug inspectionThe spark plug is an important engine compo-nent and is easy to inspect. The condition ofthe spark plug can indicate the condition ofthe engine. For example, a very white center electrodeporcelain color could indicate an intake airleak or carburetion problem for that cylinder.Do not attempt to diagnose such problemsyourself. Instead, take the ATV to a Yamaha dealer.You should periodically remove and inspectthe spark plug because heat and deposits willcause the spark plug to slowly break downand erode. If electrode erosion becomes ex-cessive, you should replace the spark plugwith one of the proper type.

However, the idling speedmay be performed by the owner as a part ofthe usual maintenance routine.

CAUTION:The carburetor was set at the Yamaha fac-tory after many tests. If the settings aredisturbed by someone without sufficienttechnical knowledge, poor engine perfor-mance and damage may result.

TroubleshootingAlthough Yamaha machines receive a rigid in-spection before shipment from the factory,trouble may occur during operation. Any prob-lem in the fuel, compression, or ignition sys-tems can cause poor starting and loss ofpower. The troubleshooting chart describes aquick, easy procedure for making checks. Ifyour machine requires any repair, take it to aYamaha dealer.The skilled technicians at a Yamaha dealer-ship have the tools, experience, and know-how to properly service your machine. Useonly genuine Yamaha parts on your machine.Imitation parts may look like Yamaha parts,but they are often inferior.

CLEANING AND STORAGE

A. CLEANINGFrequent, thorough cleaning of your machinewill not only enhance its appearance but willimprove its general performance and extendthe useful life of many components.1. Before cleaning the machine:a. Block off the end of the exhaust pipe to

prevent water entry. A plastic bag andstrong rubber band may be used.

b. Make sure the spark plug and all fillercaps are properly installed.

2. If the engine case is excessively greasy,apply degreaser with a paint brush. Donot apply degreaser to the wheel axles.

3. Rinse the dirt and degreaser off with agarden hose. Use only enough pressureto do the job.
