Warning:
1. Read and understand this instruction sheet completely before using the Trailer Dolly.
2. Design load limit is 600 lbs. for the Trailer Dolly alone, not including load supported by trailer wheels.
3. Always wear ANSI approved safety goggles when working with tools and equipment.
4. Always keep arms, feet, and legs, etc. out from under the trailer tongue while hitching, unhitching or moving the trailer.
Children should always be keep at a safe distance.
5. Always make sure the loaded trailer is blocked properly while the Trailer Dolly is being moved into place.
6. Make sure the trailer tongue is securely connected to the Trailer Dolly coupler ball before attempting to un-block and
move the trailer.
7. Take precautions to prevent uncontrolled movement of the trailer once it is connected to the Trailer Dolly. Remember, the
slope of a roadbed surface is difcult to judge, and the pull of gravity can result in a dangerously out of control trailer.
8. If the Trailer Dolly is being connected to a trailer which is being stored over a lenghty period of time, make sure both the
trailer and the Trailer Dolly are blocked properly.
9. Keep the Trailer Dolly clean and free of road dirt. Inspect the Trailer Dolly before each use to make sure all parts are
securely in place and in working order. Periodically lubricate moving parts.
