EBU00924 SAFETY INFORMATION AN ATV IS NOT A TOY AND CAN BE HAZARDOUS TO OPERATE. An ATV handles differently from other vehicles including motorcycles and cars. 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 14
Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, park- ing lots and streets. Never operate an ATV on any public street, road or highway, even a dirt or gravel one. 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, long-sleeved shirt or jacket, and long pants.
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 operate 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.
Page 17
Always use the size and type tires specified in this manual. Always maintain proper tire pressure as described in this manual. Never modify an ATV through improper installation or use of accessories. Never exceed the stated load capacity for an ATV. Cargo should be properly distributed and securely attached.
