7-30 RIDING DOWNHILL When riding your ATV downhill, shift your weight as far to the rear and uphill side of the ATV as possible. Move back on the seat and sit with your arms straight. Choose a low gear which will allow the engine compression to do most of the braking for you. Improper braking may cause a loss of traction. Use caution while descendi[...]

7-32 CROSSING A SLOPE Traversing a sloping surface on your ATV re- quires you to properly position your weight to maintain proper balance. Be sure that you have learned the basic riding skills on flat ground before attempting to cross a sloping surface. Avoid slopes with slippery surfaces or rough terrain that may upset your balance. As you travel [...]

7-35 Test your brakes after leaving the water. Do not continue to ride your ATV without verifying that you have regained proper braking ability. CAUTION: _ After riding your ATV in water, be sure to drain the trapped water by removing the check hose at the bottom of the air filter case. Wash the ATV in fresh water if it has been operated in salt wa[...]

7-36 RIDING OVER ROUGH TERRAIN Riding over rough terrain should be done with caution. Look out for obstacles which could cause damage to the ATV or could lead to an upset or accident.

7-38 SLIDING AND SKIDDING Care should be used when riding on loose or slippery surfaces since the ATV may slide. If unexpected and uncorrected, sliding could lead to an accident. To reduce the tendency for the front wheels to slide in loose or slippery conditions, position- ing your weight over the front wheels will sometimes help. If the rear whee[...]

7-39 With practice, over a period of time, skill at controlled sliding can be developed. The ter- rain should be chosen carefully before at- tempting such maneuvers, since both stability and control are reduced. Bear in mind that sliding maneuvers should always be avoided on extremely slippery surfaces such as ice, since all control may be lost. WA[...]

Be sure you are putting your weight on the footboard to the outside of the [...]

7-41 ● If your ATV is traversing a sloping surface: Be sure to ride with your weight positioned towards the uphill side of the ATV to main- tain proper balance. If the ATV starts to tip, steer down the hill (if there are no obstacles in your way) to regain balance. If you dis- cover that the ATV is going to tip over, dis- mount on the uphill side[...]
