• Connect safety chains in a crossing pattern under
the tongue with enough slack to permit turning and
to hold tongue up if trailer comes loose.
• Before towing the trailer, verify that the weight of
the trailer is equal across all tires. On trailers with
adjustable height hitches, adjust the angle of the
trailer tongue to keep the trailer as level as
possible.
Running Lights
Verify directional and brake lights on the trailer are
connected and working properly.
Wheels and Tires
Inspect trailer tires for wear and proper inflation.
•
• Verify wheel lug nuts are present and tightened to
the specified torque.
Safe Towing Techniques
Practice turning, stopping, and backing up in an
•
area away from heavy traffic prior to transporting
the unit.
• Maximum recommended speed for highway towing
is 45 mph (72 km/h). Recommended off-road towing speed is 10 mph (16 km/h) or less, depending
on terrain.
• When towing, maintain extra space between vehi-
cles and avoid soft shoulders, curbs, and sudden
lane changes.
Towing Safety
Towing a trailer requires care. Both the trailer and vehicle
must be in good condition and securely fastened to each
other to reduce the possibility of an accident. Some states
require that large trailers be registered and licensed. Contact your local Department of Transportation office to check
on license requirements for your particular unit.
Towing Vehicle
DO NOT exceed the towing vehicle’s gross vehicle weight
rating (GVWR).
Hitch and Coupling
Verify the hitch and coupling on the towing vehicle
•
are rated equal to, or greater than, the trailer's
gross vehicle weight rating (GVWR).
• Verify the trailer hitch and the coupling are compat-
ible. Verify the coupling is securely fastened to the
vehicle.
• DO NOT tow trailer using defective parts. Inspect
the hitch and coupling for wear or damage.
Reporting Trailer Safety Defects
If you believe your trailer has a defect which could cause
a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying Generac Mobile
Products LLC.
If NHTSA receives similar complaints, it may open an
investigation; and if it finds that a safety defect exists in a
group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in an
individual problem between you, your GMP ASD, or Generac Mobile Products LLC.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153),
