consequential damages.
1. Allen’s obligation and liability under this warranty is limited to repairing or replacing parts if, after Allen’s inspection, there is determined
to be a defect in material or workmanship. Allen reserves the choice to repair or replace.
2. If Allen chooses to replace the part, it will be at no cost to the customer and will be made available to the Allen Distributor, Dealer, or

SECTION 1
SAFETY
Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely and
properly over a long period of time, periodic maintenance and occasional repairs are necessary.
• ALWAYS disconnect the battery before servicing the equipment.
• DO NOT attempt to clean or service the machine while it is running. Rotating parts can cause severe injury.
• DO NOT crank a flooded engine with the spark plug removed on gasoline-powered engines. Fuel trapped in the
cylinder will squirt out the spark plug opening.
• DO NOT test for spark on gasoline-powered engines if the engine is flooded or the smell of gasoline is present. A
stray spark could ignite the fumes.
• DO NOT use gasoline or other types of fuels or flammable solvents to clean parts, especially in enclosed areas.
Fumes from fuels and solvents can become explosive.
• ALWAYS turn engine off and remove key from machine before performing maintenance or making repairs.

Transportation Safety
• 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 inated 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 tow-
ing is not to exceed 15 MPH or less depending on type of terrain.
• Avoid sudden stops and starts. This can cause skidding, or jack-kni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.
• Use tie downs to ensure machine does not move during transportation.
