SAF-HOLLAND XL-FW503 FleetMaster LowLube Series Fifth Wheels with Manual Sliding Secondary Lock XA-201-S10217, XA-201-S10579 & XA-231-S10217 - Manual (Page 8)

Attachment of Air-Activated Slide Release – If Required
1. Mount the cab control valve in accordance with the instructions provided. It should
be readily accessible to the driver, but protected to prevent accidental activation.
2. Attach an air line, using appropriate fittings to the “air” or “in” port of the valve.
Use an air source recommended by the tractor manufacturer. Use fittings and lines
of suitable pressure rating.
3. Connect an air line between the “cyl” or “out” port of the valve and the active side
of the air cylinder. A bulkhead fitting may be placed at the front of the slide base
plate, if desired. Use fittings and lines of suitable pressure rating and be sure line is
run so as not to interfere with any other operation or component.
4. Check operation of the valve and cylinder.
Inspection and Lubrication Prior to Use
1. Review the installation. Be sure all nuts and bolts are in place and properly
tightened. Be sure all necessary steps were properly followed and that all
components removed to facilitate installation are reinstalled.
2. Check the fifth wheel locking mechanism with a Holland TF-TLN-5001 (2˝) or
TF-TLN-1500 (3-1/2˝) Lock Tester. Examine for proper locking as described in the
“Operating Instructions” of this manual. This must be done to assure that the
mechanism has not been damaged by shipment, handling, or storage.
Failure to properly install, operate, or maintain this fifth wheel could
result in tractor and trailer separation causing death or serious injury
to others.
3. Apply grease to the bearing surface of the support bracket through the grease
fittings on the side or front of the fifth wheel pockets. The top plate must
be lifted up slightly to ensure proper application of grease. (NOTE: This is not
required on Holland LowLube and NoLube top plates.)
4. Apply a generous coating of grease to the top of the fifth wheel plate, where it will
contact the trailer plate. (NOTE: This is not required on Holland LowLube and
NoLube top plates.)
5. Apply a generous coating of grease to the front lock and lock jaws.
