or move, causing death or serious injury.
WARNING
WARNING
Property or Equipment Damage. Tighten wheel lug
nuts after first 50 miles to factory specifications.
Failure to do so could result in death, serious injury,
property or equipment damage. (000235)
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.
Hitch and Coupling
WARNING
(000233a)
Personal injury. Trailer must be securely coupled to the
hitch with the chains correctly attached. Uncoupled or
unchained towing could result in death or serious injury.
WARNING
Property or equipment damage. Do not alter the
trailer. Alterations can damage essential safety items.
Doing so could result in death, serious injury, or
property or equipment damage.
(000285)
•Verify the hitch and coupling on the towing vehicle
are rated equal to, or greater than, the trailer's
gross vehicle weight rating (GVWR).
•DO NOT tow trailer using defective parts. Inspect
the hitch and coupling for wear or damage.
•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 tow-
ing 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.
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.
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 dealer, or
Generac Mobile.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-888-327-4236 (TTY:1-800-424-9153),
go to http://www.safercar.gov; or write to:
