Mount Truck Bed Extender keep work
area clean and well lighted. Keep specta-
tors and children out of the work area.
3. Use of the Truck Bed Extender
A. The Truck Bed Extender must be at-
tached to a 2” x 2” Class III or Class IV
hitch receiver. The hitch receiver must be
properly installed by a qualied service tech-
nician and be certied to support the weight
of this Truck Bed Extender and its contents
(350 Lbs. maximum load capacity, evenly
distributed).
B. This Truck Bed Extender is designed
for transporting longer payloads such as
lumber, drywall sheets, extra-long ladders,
pipes, canoes and more. Do not modify
the Truck Bed Extender and do not use
this product for purposes that it was not
designed for.
C. Never exceed the maximum load capacity
of 350 Lbs., evenly distributed.
D. Be aware of the danger of “dynamic
loading”. This situation arises when a load
is dropped onto the Truck Bed Extender,
resulting in a short term excessive load.
Dynamic loading can result in damage and
failure of the Truck Bed Extender and/or
hitch receiver, and personal injury to the per-
son loading the Truck Bed Extender.
E. Never load people or animals onto the
Truck Bed Extender. Keep children and
spectators well clear when loading, unload-
ing and using this product.
F. Adhere to all Department of Transpor-
tation (D.O.T.) requirements when using
this product. Use ropes and tie downs to
securely hold all cargo in place. Attach the
provided red warning ag (A17) to the back
of the load for added visibility.
G. For the vehicle that will support the
Truck Bed Extender, read all pertinent vehi-
cle instructions and warnings provided in the
owner’s manual. Make sure the vehicle’s
engine is OFF, with parking brake set, be-
fore setting-up, loading or unloading the
Truck Bed Extender.
H. Weight loaded onto the Truck Bed
Extender should be evenly distributed
acrosss the full width of the Cross Beam
(A4).
I. Note the position of the vehicle’s ex-
haust pipes before setting up the Truck
Bed Extender. Make sure exhaust pipes
are not in close proximity of the Truck Bed
Extender. Materials loaded onto the Truck
Bed Extener could catch on re due to heat
from exhaust. If this risk exists on your
vehicle, do not use the Truck Bed Extender.
Keep in mind that the warnings previous-
ly discussed cannot cover all possible
conditions or situations that could
occur. It is important that the person
loading/unloading and using this product
understand that common sense and cau-
tion are factors which cannot be built into
this product, and must be supplied by the
person(s) using this product.
