Always check the terrain carefully before you start up any hill.
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. When crossing the side of a hill: Always follow proper procedures as described in the Owner’s Manual. Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV.
qWARNING If your ATV has stalled or stopped and you believe you can continue up the hill, restart carefully 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. Physically turn the ATV around and then descend the hill. POTENTIAL HAZARD Stalling, rolling backwards or improperly dismounting while climbing a hill. WHAT CAN HAPPEN Could result in the ATV overturning.
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 procedure described in the Owner’s Manual.
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 descending a hill with loose or slippery surfaces. Braking ability and traction may be adversely affected by these surfaces.
OK 7-31
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. Avoid slopes with slippery surfaces or rough terrain that may upset your balance. qWARNING POTENTIAL HAZARD Improperly crossing hills or turning on hills. WHAT CAN HAPPEN Could cause loss of control or cause the ATV to overturn.
Avoid hills with excessively slippery or loose surfaces. Shift your weight to the uphill side of the ATV.
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. Drive slowly and carefully. HOW TO AVOID THE HAZARD Never operate this ATV in fast flowing water or in water deeper than that specified in your Owner’s Manual.
cC Test your brakes after leaving the water. Do not continue to ride your ATV without verifying that you have regained proper braking ability. 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 water or muddy conditions. q 1.
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. Avoid jumping the ATV as loss of control and damage to the ATV may result. qWARNING POTENTIAL HAZARD Improperly operating over obstacles. WHAT CAN HAPPEN Could cause loss of control or a collision. Could cause the ATV to overturn.
7-37
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. If the rear wheels of your ATV start to slide sideways, control can usually be regained (if there is room to do so) by steering in the direction of the slide.
qWARNING With practice, over a period of time, skill at controlled 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 maneuvers should always be avoided on extremely slippery surfaces such as ice, since all control may be lost. POTENTIAL HAZARD Skidding or sliding improperly. WHAT CAN HAPPEN You may lose control of this ATV.
8 If your ATV starts to slide sideways: Steer in the direction of the slide if you have the room. Applying the brakes or accelerating is not recommended until you have corrected the slide. (See pages 7-38~7-39.) 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 turning maneuvers again.
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. If you discover that the ATV is going to tip over, dismount on the uphill side. (See pages 7-32~7-33.) 8 If your ATV encounters shallow water: Ride slowly and carefully through slow moving water, watching for obstacles.
