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 Owners 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. OWNERS MANUAL The Waltco Owners 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 owners 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, wear and part deformation. Check cylinder and hose for leaks. Inspections and repairs should be made by a qualified mechanic. REPLACEMANT 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 TRUCK EQUIPMENT COMPANY. 80101388 Rev 01 Chapter 1 Safety Information The following safety information must be read before operating Waltco liftgates. Read and understand the Owner’s Manual and all decals on liftgate before operating liftgate. Do not operate liftgate without a thorough knowledge and understanding of the operation of the liftgate. Liftgate hazards can result in crushing or falling This liftgate is designed for loading and unloading of cargo. If personnel are required to ride liftgate, observe and familiarize yourself with the liftgate operation, decals and manuals. Ensure stable footing at all times Do not ride liftgate with unstable loads. Keep hands and feet clear of all potential pinch points. Do not attempt any repairs unless you are qualified to do so. Care should be taken when work is performed on a disabled liftgate located near moving traffic. When possible the vehicle should be moved away from traffic areas for repair. Precautionary measures should be taken to ensure personal safety including those recommended in Federal Motor Vehicle Safety Standards 571.125. NEVER OVERLOAD LIFTGATE Refer to the Explanation of Specification Tag in the Liftgate Terminology chapter for liftgate capacity rating. Never use liftgate if it makes any unusual noise, has unusual vibration, raises or lowers unevenly, or fails to operate smoothly. Never use liftgate if it shows any signs of structural damage such as cracked welds, bent or distorted members. For liftgates with Runners, never use liftgate if Runners do not travel freely and smoothly. All protective covers, guards, and safety devices must be in place and access doors closed before operating liftgate. Make certain the Platform area, including the area in which loads may fall, is clear before and at all times during the operation of the liftgate. For liftgates with Roller Lifting Chain, the Chain should be replaced every (5) five years or 15,000 cycles, whichever comes first. Replace only with Waltco approved Roller Chain. A Lock-Out device or Shut-Off Switch should always be used to prevent unauthorized use of liftgate. Never transfer loads which exceed lifting capacity on or over any part of the Platform unless the liftgate is equipped with a special reinforced Platform and Platform Support Bars for use when the Platform is used as loading ramp (dock board). Refer to the “Using Platform as a loading ramp” Chapter in the Operation Instructions of the BZ/RZ series Owner’s Manual. Platform is always to be properly stored and secured for transit. See the Owner’s Manual for details. For liftgates equipped with Trailer Hitches, never exceed the rated capacity of the hitch. Do not exceed the vehicle’s weight rating. Refer to the vehicle’s Owner’s Manual. Page 1 - 1 80101253 Rev 02 Chapter 1 Safety Information Take care to retain cargo during transit for liftgate Platforms which function as the tailgate or door of the cargo area. Small objects can fall through the space between the vehicle and the folded Platform. Vehicle must comply with all state and federal standards. Follow the “Maintenance Guide” chapter in the Owner’s Manual. Liftgates with Tilt Function Proper use of the Control Switches is of extreme importance. Improper use of Tilt Switch could cause load to fall from the Platform or damage the liftgate. Platform should be in a generally horizontal position when raising or lowering with a load. In any tilt position, the Platform may vary from level while raising or lowering the Platform. Liftgates equipped with spring operated Cam Closer Replace Cam Release Spring every five (5) years or 15,000 cycles, whichever comes first. RGL Make certain Platform Brake mechanisms are operating properly. The Runners are always to remain powered up against the Upstops Pins when in transit. Inspect Cables every three (3) months or 750 cycles, whichever comes first. Cables must be replaced if they show signs of wear, distortion, kinking or if any broken wires are visible Replace cables every five (5) years or 10,000 cycles, whichever comes first.
