„alWaYs shutdown engine before transporting

„Make sure the hitch and coupling of the towing vehicle are rated equal to, or greater than the trailer “gross vehicle weight rating.”

„alWaYs inspect the hitch and coupling for wear. never tow a trailer with defective hitches, couplings, chains, etc.

„Check the tire air pressure on both towing vehicle and trailer. Trailer tires should be inflated to 50 psi cold. Also check the tire tread wear on both vehicles.

„alWaYs make sure the trailer is equipped with a safety chain.

„alWaYs properly attach trailer’s safety chains to towing vehicle.

„alWaYs make sure the vehicle and trailer directional, backup, brake and trailer lights are connected and working properly.

„DOT Requirements include the following:

•Connect and test electric brake operation.

•Secure portable power cables in cable tray with tie wraps.

„The maximum speed for highway towing is 55 mph unless posted otherwise. Recommended off-road towing is not to exceed 15 mph or less depending on type of terrain.

„Avoid sudden stops and starts.This can cause skidding, or jack-knifi ng. Smooth, gradual starts and stops will improve towing.

„Avoid sharp turns to prevent rolling.

„Trailer should be adjusted to a level position at all times when towing.

„Raise and lock trailer wheel stand in up position when towing.

„Place chock blocks underneath wheel to prevent rolling while parked.

„Place support blocks underneath the trailer’s bumper to prevent tipping while parked.

„Use the trailer’s swivel jack to adjust the trailer height to a level position while parked.
