A collision or rollover can occur quickly, even during routine maneuvers such as turning and riding on hills or over obstacles, if you fail to take proper precautions.
  • Page 15 Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You should also wear eye protection (goggles or face shield), gloves, boots, a long-sleeved shirt or jacket, and long pants. Never consume alcohol or drugs before or while operating this ATV. Never operate at speeds too fast for your skills or the conditions.
  • Page 16 Always follow proper procedures for climbing hills as described in this manual. Check the ter- rain carefully before you start up any hill. Never climb hills with excessively slippery or loose surfaces. Shift your weight forward. Never open the throttle suddenly or make sudden gear changes.
  • Page 17 Always be careful when skidding or sliding. Learn to safely control skidding or sliding by prac- ticing at low speeds and on level, smooth terrain. On extremely slippery surfaces, such as ice, go slowly and be very cautious in order to reduce the chance of skidding or sliding out of con- trol.
