XL-FW487 Rev B SAF-HOLLAND, Inc. 3
OPERATION INSTRUCTIONS
Coupling
1. Back up closer to the trailer, centering the kingpin on the throat of the fifth wheel.
STOP. Set tractor brakes.
2. Block the trailer wheels, connect brake lines and set trailer brakes.
3. Check to see that the trailer is at the proper height for coupling. (The front of the
bolster plate should contact the fifth wheel approximately 4˝ to 6˝ behind the fifth
wheel’s pivot point. If not, raise or lower the fifth wheel and, if necessary, the trailer
landing gear, to obtain this position.)
4. Back under the trailer and engage the fifth wheel locks with the trailer kingpin. Pull
forward to test the completeness of the coupling as an INITIAL check. Set tractor
brakes. Next, visually inspect the fifth wheel, as shown in Figure 3, to verify that it is
properly locked
Failure to verify a
proper couple can
result in tractor and trailer separation,
causing death or serious injury to you or
other (see Figure 3).
5. If operation on public streets or
highways is required, the manual
secondary lock must be engaged. To
engage the secondary lock, remove
the hairpin clip on the secondary
lock handle allowing the secondary
lock to pivot behind the locking
yoke as shown in Figure 4.
6. Remove blocks. Release trailer
and tractor brakes. Raise trailer to
desired height and move trailer.
Elevating fifth wheels
in the elevated
position are less stable than standard
fifth wheels. To avoid rollovers, do not
travel at excessive speeds, and do not
make sudden turns or maneuvers.
This unit is not
recommended
for operation on public streets and
highways. When such trailer moves are
necessary, the manual secondary lock
on the fifth wheel must be engaged
(see coupling procedure #5 above)
and the fifth wheel must be in the
down position. Limit speed to 45 mph
maximum.
