Coupling of the Towing Vehicle
to the Trailer
Keep all personnel clear of front, rear, and sides
of towing vehicle and trailer during coupling,
component operations, and uncoupling. Failure
to stay clear can result in serious personal injury
or death.
1. Verify the trailer wheels are chocked and brakes
function properly.
2. Make sure the towing vehicle's coupler is open.
3. Raise or lower the pintle hitch eye to hitch height by
activating the bed tilt hydraulic lever, which is the
front most lever of the three levers (See "Trailer Tilt
Lever" on page 3-7.)
Pushing the trailer backwards can damage
parking stands.
4. Slowly back the towing vehicle so the hitch contacts
the trailer hitch. Make sure the hitch is centered and
will properly connect up. Set the vehicle brakes.
5. Lower pintle eye onto truck hitch by tilting bed up and
lock the hitch in place.
6. Raise the landing gear (parking stands) by first tilting
the bed up, activating the front hydraulic lever until
the landing gear is off the ground. Remove pins from
landing gear and slide landing gear fully up to stowed
position. Insert and lock pin holding landing gear in
stowed position. Fully lower bed tilt.
IMPORTANT
Keep brakes engaged for remainder of hookup,
check-out procedures, and for parking.
