WARNING
Fully instruct and demonstrate the operation of this 5th wheel hitch to the end user. Include the
importance of observing all warnings contained herein, including warning labels on 5th wheel
hitch main body. Provide this manual in its entirety to the end user. Serious injury or death may
result if the warnings above are not observed.
Do not expose hands, body parts or clothing between the truck and
trailer or the truck's bed sides and trailer. If you must place any part
of your body under trailer or between truck and trailer, you must:
1. Block all trailer tires with wheel chocks.
2. Make sure trailer landing gear / jacks are resting on a firm, level surface.
3. Towing vehicle must be stationary with auto transmission in park
(manual in neutral), emergency brake applied and engine off.
Never exceed the towing capacity (trailer and contents combined)
of any towing system component or your vehicle.
Improperly coupled trailers can separate or drop without notice,
causing serious injury or death. To reduce the chance of serious injury or death:
Never attempt to couple trailer without reading and following all instructions thoroughly.
Always follow operating instructions to secure trailer to tow vehicle.
Make sure the hitch is secure before towing.
Prior to towing, ensure all components and hardware are structurally sound and secure.
Always chock the trailer to prevent movement while coupling the hitch.
Always ensure lynch pins are installed through handle before towing.
Always perform a pull test prior to towing. See 'pull test' later in this instruction manual.
Never position anyone under the trailer's kingpin area during coupling and uncoupling.
Do not torque upper M20 head pivot bolt (#6). The nut is designed to only make contact but not
apply clamping force. If bolt is torqued it could cause bolt to fail causing hitch separation during
use leading to severe injury or death. If hitch head appears loose the 20mm bolt can be removed
and inspected for damage if any cracks or damage is visible immediately discontinue use of hitch.
NOTICE
Before you begin installation,
read all instructions thoroughly.
Proper tools will improve the quality of
installation and reduce the time required.
To help prevent damage to the product
or vehicle, refer to the specified torque
specifications when securing hardware
during the installation process.

manufacturer's specifications) before each use and every
1,000 miles. Failure to do so may allow bolts to become
