When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly. As you slow down, shift to a lower gear. Be sure that the engine has sufficiently slowed before engaging a lower gear.
7-23 TURNING YOUR ATV To achieve maximum traction while riding off- road, the two rear wheels are mounted solidly on one axle and turn together at the same speed. Therefore, unless the wheel on the inside of the turn is allowed to slip or lose some traction, the ATV will resist turning.
7-24 This procedure should be practiced at slow speed many times in a large off-road area with no obstacles. If an incorrect technique is used, your ATV may continue to go straight. If the ATV doesn’t turn, come to a stop and then practice the procedure again.
7-25 CLIMBING UPHILL Use proper riding techniques to avoid vehicle overturns on hills. Be sure that you can maneu- ver your ATV well on flat ground before attempt- ing any incline and then practice riding first on gentle slopes. Try more difficult climbs only after you have developed your skill.
7-26 POTENTIAL HAZARD Climbing hills improperly. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn. HOW TO AVOID THE HAZARD Always follow proper procedures for climbing hills as described in this Owner’s Manual. Always check the terrain carefully before you start up any hill.
7-27 If you are climbing a hill and you find that you have not properly judged your ability to make it to the top, you should turn the ATV around while you still have forward motion (provided you have the room to do so) and go down the hill. POTENTIAL HAZARD Improperly crossing hills or turning on hills.
7-28 If your ATV has stalled or stopped and you believe you can continue up the hill, restart care- fully to make sure you do not lift the front wheels which could cause you to lose control. If you are unable to continue up the hill, dismount the ATV on the uphill side.
7-29 When fully stopped, apply rear brake as well, and then lock parking brake. Dismount on uphill side or to a side if pointed straight uphill. Turn the ATV around and remount, following the proce- dure described in the Owner’s Manual.
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.
7-31 OK.
7-32 CROSSING A SLOPE Traversing a sloping surface on your ATV requires 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.
7-33 Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV. OK.
7-34 CROSSING THROUGH SHALLOW WATER The ATV can be used to cross slow moving, shallow water of up to a maximum of 35 cm (14 inches) in depth. Before entering the water, choose your path carefully. Enter where there is no sharp drop off, and avoid rocks or other obstacles which may be slippery or upset the ATV.
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. c C 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.
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. Be sure to keep your feet firmly mounted on the footboards at all times.
7-37.
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, positioning your weight over the front wheels will sometimes help.
7-39 With practice, over a period of time, skill at con- trolled sliding can be developed. The terrain should be chosen carefully before attempting such maneuvers, since both stability and control are reduced. Bear in mind that sliding maneu- vers should always be avoided on extremely slippery surfaces such as ice, since all control may be lost.
7-40 WHAT TO DO IF ... This section is designed to be a reference guide only. Be sure to read each section on riding techniques completely. WHAT TO DO ... 8 If your ATV doesn’t turn when you want it to: Bring the ATV to a stop and practice the turn- ing maneuvers again.
7-41 8 If your ATV is traversing a sloping surface: Be sure to ride with your weight positioned towards the uphill side of the ATV to maintain proper balance. If the ATV starts to tip, steer down the hill (if there are no obstacles in your way) to regain balance.
