7-17 1 2 3 4 5 6 7 8 9 10 11 EWB01070 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. There- fore, unless the wheel on the inside of the turn is al- lowed to slip or lose some traction, the ATV will resist turning.
7-18 1 2 3 4 5 6 7 8 9 10 11 This procedure should be practiced at slow speed many times in a large off-road area with no obsta- cles. 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 proce- dure again.
7-19 1 2 3 4 5 6 7 8 9 10 11 It is important when climbing a hill to make sure that your weight is transferred forward on the ATV. This can be accomplished by leaning forward and, on steeper inclines, standing on the footboards and leaning forward over the handlebars.
7-20 1 2 3 4 5 6 7 8 9 10 11 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.
7-21 1 2 3 4 5 6 7 8 9 10 11 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 up- hill side.
7-22 1 2 3 4 5 6 7 8 9 10 11 RIDING DOWNHILL When riding your ATV downhill, shift your weight as far to the rear and uphill side of the ATV as pos- sible. Move back on the seat and sit with your arms straight. Choose a low gear which will allow the en- gine compression to do most of the braking for you.
7-23 1 2 3 4 5 6 7 8 9 10 11 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.
7-24 1 2 3 4 5 6 7 8 9 10 11 steering when riding on loose surfaces by pointing the front wheels slightly uphill. When riding on slopes, be sure not to make sharp turns either up or down hill. If your ATV does begin to tip over, gradually steer in the downhill direction if there are no obstacles in your path.
7-25 1 2 3 4 5 6 7 8 9 10 11 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 care- fully. EWB01150 Test your brakes after leaving the water.
7-26 1 2 3 4 5 6 7 8 9 10 11 NOTICE ECB00240 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.
7-27 1 2 3 4 5 6 7 8 9 10 11 SLIDING AND SKIDDING Care should be used when riding on loose or slip- pery surfaces since the ATV may slide. If unex- pected and uncorrected, sliding could lead to an accident.
7-28 1 2 3 4 5 6 7 8 9 10 11 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 re- duced.
7-29 1 2 3 4 5 6 7 8 9 10 11 Lean more into the turn to regain balance. If nec- essary, gradually let off the throttle and/or steer to the outside of the turn. (See page 7-17.) ● If your ATV starts to slide sideways: Steer in the direction of the slide if you have the room.
