CAUTION
1. Practice all standard industrial safety standards. Do
not load any payload that will overload any
component of the trailer or cause an unsafe
condition.
2. Park the tractor/semitrailer in a straight line on level
even surface. Set the tractor brakes and release the
semitrailer brakes
(See Figure 3-7.)
3. Start operation of hydraulic power system. If the
hydraulic engine package is installed, start and warm
up engine following engine operating instructions in
“Hydraulic Power Supply Engine Operation
(Option)” on page 3-20 (Read engine operator’s
manual.)
4. Move undercarriage forward (out of pockets) five to
eight feet using the
AXLE CONTROL lever (See
“Axle Control Lever” on page 3-8.) To insure that
the trailer does not rock back, keep undercarriage
behind the trailer center of gravity.
5. If winch cable is connected to lower bed, disconnect
cable from lower bed or reel out cable as needed to
keep it from becoming too tight when tilting bed
(See
“Winch Controls” on page 3-15.) Using the
TRAILER TILT lever tilt the front of the bed up until
approach plate touches the ground or is to full tilt
position
(See “Trailer Tilt Lever” on page 3-8.)
6. If the approach plate has not touched the ground,
move undercarriage forward until approach plate just
touches the ground.
7. Alternate between lowering bed tilt angle and moving
undercarriage fully forward so weight of the trailer
bed rests partly on approach plate and partly on
undercarriage as undercarriage is moved forward.
Reel winch in or out as needed to keep some tension
on cable. The object is to have the approach plate
resting on the ground whenever the center of gravity
of the trailer and load is behind the center of the
undercarriage. In loading or unloading position, the
approach plate should be resting on the ground and
the undercarriage fully forward.

WARNING
IMPORTANT
Maximum angle is only intended if required for
unloading non-powered products and to transfer
load to tractor. Transfer load to tractor by raising
deck and moving axles rearward until load is forward
of rear axle, thus applying load to tractor.
8. Winch or drive the load onto the semitrailer. Insure
that the load is steering straight up onto the
semitrailer and does not maneuver off the side of the
semitrailer. Continue until load center of gravity is just
ahead of the axles, if possible. The load should never
place more weight on the kingpin than on the rear
axles during loading and unloading.
1. Do not go near undercarriage when cam
rollers are partially out of pockets. Check that
cam rollers are completely in, or completely
out of pockets. If a hydraulic hose is
disconnected from the system, the
undercarriage could slide abruptly into the
pockets.
2. The center of gravity of the load must be in
front of the center of the undercarriage
whenever the approach plate is not supported
by the ground. Failure to do this can cause
the semitrailer to tilt back and can result in
injury or death.
3. Keep all persons clear while tilting trailer to
avoid serious injury or death by being
pinched in trailer bed.
Do not allow the back trailer axle to leave the
ground. This can result in damage to semitrailer.
Tilting the semitrailer deck will increase tension
on the winch cable, which can cause the load to
be pulled forward. Do not hook the cable to the
lower deck when tilting.
In loading or unloading position, the approach
plate should be resting on the ground and the
undercarriage fully forward.
Always use low load angle to load and unload
powered products.
