nstructions
Read and observe all Warning and Caution
hazard alert messages in this publication.
They provide information that can help
prevent serious personal injury, damage to
components, or both.
All fifth wheel installation and maintenance must be performed by a properly
trained technician using proper tools and
safe procedures.
IMPORTANT: Prior to operation of the
fifth wheel you must be
thoroughly satisfied that
the fifth wheel has been
appropriately installed
on the vehicle.
Failure to properly install
the fifth wheel may result in
tractor trailer separation
which, if not avoided, could
result in death or serious
injury.
Refer to SAF-HOLLAND Installation Manual
XL-FW10008IM-en-US (available on the
Internet at www.safholland.us) for proper
installation procedures.
Failure to follow all the
operating procedures
contained in these
instructions may result
in a hazardous
condition which, if not
avoided, could result
in death or serious
injury.
These instructions apply to the proper
operation of your fifth wheel only.
There are other important checks,
inspections, and procedures not
listed here that are necessary,
prudent, and/or required by law.
Only SAF-HOLLAND Original Parts
should be used.

appropriate position for
weight distribution on the
tractor. For proper positioning
of the fifth wheel refer to
SAF-HOLLAND publication

6. Lower landing gear until pads just
touch the ground (F
igure 12).
NOTE: Follow instructions published by
manufacturer for proper operation
of landing gear and ability to
transfer trailer weight off fifth
wheel. Do not raise trailer off the
fifth wheel.
7. Disconnect brake lines and light cord.
8. Slide release handle forward, pull all
the way out, slide handle forward and
hook on casting (F
igure 13). If air
release equipped, actuate fifth wheel
control valve to open locks.
9. Release tractor brakes and slowly
drive away from trailer.
8. Positioning Sliding
Fifth Wheels
1. Position tractor and trailer in a
straight line on level ground.
2. Lock trailer brakes.
Failure to stop and
properly lock the trailer
brakes may cause
uncontrolled sliding of fifth
wheel which, if not
avoided, may result in
component damage to
tractor or trailer.
3. Release slide locking plungers by
moving cab switch to unlock position
(F
igure 14). (If manual slide release
equipped, pull release lever.) If
plungers do not come out, lower the
landing gear to relieve pressure on
the fifth wheel. This will allow fifth
wheel to slide easier.
NOTE: Cab switch style may differ by OEM
design.

7. Verify that slide locking plungers have
been re-engaged by performing a pull
test . Lock trailer brakes and pull forward with tractor to make sure fifth
wheel does not slide (F
igure 16).
IMPORTANT: Do not operate the vehicle
if the plungers are not fully
engaged (locked).
Failure to properly engage
plungers into slide base may
cause loss of vehicle control
which, if not avoided, could
result in death or serious
injury.
FIFTH WHEEL MAINTENANCE
IMPORTANT: All maintenance must be
performed by a properly
trained technician using
proper tools and safe
procedures.
IMPORTANT: All maintenance must be
performed while the tractor is
uncoupled from the trailer.
Failure to properly maintain
your fifth wheel could result
in tractor trailer separation
which, if not avoided, may
result in death or serious
injury.

10. Fifth Wheel Lubrication
IMPORTANT: Fifth wheel lubrication is
necessary to get the maxi mum service life from your
FW17 fifth wheel. Perform
the following procedures at
the intervals shown.

Maintenance Procedures
Lubricate locking mechanism every 3
months or 30,000 miles.
Thoroughly clean the locking
mechanism every 6 months or
60,000 miles.
IMPORTANT: If your fifth wheel operates in
snowy or icy winter
conditions, lubrication
should be performed every
spring in addition to routine
lubrication (as noted above),
to ensure optimum opera
tion.

4. Slide the lock tester forward and
backward in the closed lock to check
for play between lock and kingpin.
Ensure that the tool remains flat with
full contact on the fifth wheel top
plate. Use pin gage to measure free
play. If free play exceeds 0.080”.
