resulting in a loss of directional control. Avoid higher speeds until you are thoroughly familiar with the operation of your ATV. When slowing down or stopping, release the throttle and apply the brakes smoothly and evenly. Improper use of the brakes can cause the tires to lose traction, reducing control and increasing the possibility of an accident.
Page 82
To achieve maximum traction while riding off- road, the two rear wheels 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. A special turn- ing technique must be used to allow the ATV to make turns quickly and easily.
Page 83
Improper riding procedures such as abrupt throt- tle changes, excessive braking, incorrect body movements, or too much speed for the sharpness of the turn may cause the ATV to tip. If the ATV be- gins to tip over to the outside while negotiating a turn, lean more to the inside.

Page 85
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. When- ever possible, ride straight up hills.
If you start to roll backwards, DO NOT apply either brake abruptly. If you are in “2WD”, apply only the front brake. When fully stopped, apply the rear brake as well, and then shift to the park position. If you are in “4WD”, because all wheels are inter- connected by the drive train, applying either brake will brake all wheels, therefore, avoid sudden ap- plication of either the front or rear brake as the...

To reduce your risk of drowning or other injuries, use care when crossing through water.
