Taking Care of the Unexpected
Should you ever have a problem while riding, please follow these
guidelines:
Always put personal safety first.
Take time to assess the situation and your options before deciding
what to do.
If the problem is relatively minor and you have the tools, supplies,
and skills to make a temporary repair, be sure to have permanent
repairs made as soon as possible.
Do not continue riding if you are hurt or your ATV is not in safe
riding condition.
Additional recommendations for specific problems follow.
