    06/10/24 13:08:29 32HP4800_084 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 84 06/10/24 13:08:37 32HP4800_085 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 85 06/10/24 13:08:50 32HP4800_086 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 86 06/10/24 13:09:00 32HP4800_087 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.

    06/10/24 13:21:23 32HP4800_159 Tyres To safely operate your ATV, your tyres must be the proper type and size, in good condition with adequate tread, and correctly inflated. Using tyres that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed.
  • Page 159 06/10/24 13:21:29 32HP4800_160 Tyres Air Pressure Refer to Saf ety Precautions on page Properly inflated tyres provide the best combination of handling, tread life, and riding comfort. Generally, underinflated tyres wear unevenly, adversely affect handling, and are more likely to fail from being overheated.
  • Page 160 06/10/24 13:21:38 32HP4800_161 Tyres Always check air pressure when your tyres are ‘‘cold.’’ If you check air pressure when your tyres are ‘‘warm’’ even if your ATV has only been ridden for a few miles the readings will be higher. If you let air out of warm tyres to match the recommended cold tyre pressures, the tyres will be underinflated.
  • Page 161 06/10/24 13:21:49 32HP4800_162 Tyres A manually operated tyre pump should be used rather than the high pressure system found in service stations. This will minimize the possibility of tyre damage from overinflation. If you use a high pressure system at a service station, add air in small amounts and check the pressure increase frequently to prevent possible tyre damage from overinflation.

A temporary repair can sometimes be made in an emergency situation. However, since a temporary repair may not hold, you must ride very slowly, preferably without any cargo, and have the tyre replaced or permanently repaired as soon as possible.
