  • Page 15 Always follow proper procedures for turning as described in this manual. Practice turning at low speeds before attempting to turn at faster speeds. Do not turn at excessive speed. Never op- erate the ATV on hills too steep for the ATV or for your abilities. Practice on smaller hills before attempting larger hills.
  • Page 16 Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stall- ing, use proper gear and maintain a steady speed when climbing a hill. If you stall or roll back- wards, follow the special procedure for braking described in this manual. Dismount on the uphill side or to a side if pointed straight uphill.
