INTRODUCTION
If anyone observes improper installation, improper operation, or damage, they should immediately
contact a qualified person for assistance and correction. We strongly urge anyone that has any questions
or doubts as to the installation, condition, use, operation, maintenance or repair of the liftgate to contact
us at Waltco where we have qualified personnel that will be happy to assist you. Telephone numbers and
addresses of these locations are listed in the Owner’s Manual and Installation Instructions.
INSTALLATION
Waltco liftgates should only be installed by those with sufficient basic skills to understand the
installation and operation of the liftgate, along with the equipment on which the liftgate is being installed.
Waltco’s installation instructions are not intended to give rationale for all the instructions that are given;
however, it is the intent of these instructions to give the installer both the operations and what we believe
to be the most desirable sequence of implementing these operations. These instructions can in no way
expand into an area where they will replace a qualified person, or clear thinking and a basic knowledge
that must be possessed by the installer.
It has been our experience that a knowledgeable journeyman following these instructions and
observing the operation of the liftgate will have a sufficient comprehension of the liftgate to enable this
person to troubleshoot and correct all normal problems that may be encountered.
Failure to follow the installation instructions, adjustments and mounting dimensions may result in
improper and unsafe operation of the liftgate. Unauthorized alterations of the liftgate can cause an
undesirable and dangerous condition.
OWNER’S MANUAL
The Waltco Owner’s Manual is intended to act as a guide for operation and routine maintenance but
is no way intended to encourage usage or repair of the liftgate by those who are not qualified to do so.
The contents of the owner’s manual include, but are not limited to general operation instructions,
routine lubrication, parts lists, and an outline of things that should be checked but may not be obvious to
those not technically qualified. This manual assumes the liftgate is properly installed, undamaged and
operates correctly. Improper installation, improper operation, or damage should be immediately corrected
by a qualified person.
INSPECTION
As part of the regular inspection of a liftgate and after damage or suspicion of an overload, inspect for
wear or structural damage and make necessary repairs or replacements. Check all structural components
and their attachment to the liftgate for cracked welds, loose fasteners, wear and part deformation. Check
cylinder and hose for leaks. Inspections and repairs should be made by a qualified mechanic.
REPLACEMENT PARTS
Use only Waltco original equipment replacement parts. Components of other liftgate manufacturers
may outwardly appear to be the same but are not interchangeable with Waltco products. Waltco
components are specifically designed for safety requirements, reliability and compatibility with our
products. Refer to your Waltco parts manual when ordering parts. NOTE: When ordering, give model and
serial number of liftgate.
DECALS
It is important that every vehicle that has a WALTCO Liftgate have legible DECALS clearly posted on
the vehicle and an OWNER’S MANUAL in the vehicle at all times as a guide for proper operation and
maintenance.
Additional DECALS and OWNER’S MANUALS can be obtained from WALTCO LIFT CORP.
