  • Page 82: Riding Up Hills

    Riding Your ATV Riding Up Hills The ATV’s ability to safely climb hills largely depends on the rider’s skill and judgment. Begin by practicing on smooth, gentle slopes. As you gain experience, you’ll learn the hazards and your own limitations. You may then proceed to ride on more difficult terrain.
  • Page 83 Riding Your ATV Shift weight forward when climbing hills. Always check the terrain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces. To climb a hill, take a running start in an appropriate gear and speed for the conditions.
  • Page 84 Riding Your ATV Stalling the ATV and/or Rolling Backwards: If you incorrectly estimate climbing capability or terrain conditions, the ATV may not have enough power or traction to continue uphill. If this happens, the ATV can stall and/or roll backwards. Stalling, rolling backwards or improperly dismounting while climbing a hill could result in the ATV overturning.
  • Page 85 Riding Your ATV What to do after the ATV has stalled or rolled backwards: If the hill is too steep or too slippery, or if you have any doubt whether you can safely walk the ATV back down the hill, leave the vehicle where it is and get help.

  • Page 86: Riding Down Hills

    Riding Your ATV Riding Down Hills It’s usually advisable to descend hills with the ATV pointed straight downhill. Avoid angles that would cause the vehicle to lean sharply to one side. Going down a hill improperly could cause loss of control or cause the ATV to overturn. Always follow proper procedures for going down hills as described in this owner’s manual.

  • Page 87: Crossing Or Turning On Hills Or Slopes

    Riding Your ATV When you’ve selected a safe downhill path, shift into a lower gear, shift your weight back with your arms extended and braced against the handlebar, then go down slowly with the throttle closed. Use mainly the rear brake to control speed. Avoid using either the front brake or rear brake hard or abruptly when riding down hills.
  • Page 88 Riding Your ATV Crossing Hills or Slopes To maintain balance and stability when riding across a slope, you need to shift weight toward the uphill side of the vehicle. To do this, move your body off the center of the seat and lean toward the uphill side.

  • Page 89: Riding Over Obstacles

    Riding Your ATV Riding Over Obstacles Before operating in a new area, check for obstacles. Watch out for bumps, rain ruts, potholes and other obstacles in the terrain.
