•Do not stand, or allow obstructions, under the platform when lowering the Liftgate. Be sure your
feet are clear of the Liftgate.
• Keep fingers, hands, arms, legs, and feet clear of moving Liftgate parts (and platform
edges) when operating the Liftgate.
•Make sure vehicle battery power is disconnected while installing Liftgate. Connect vehicle
battery power to the Liftgate only when installation is complete or as required in the installation
instructions.
•If it is necessary to stand on the platform while operating the Liftgate, keep your feet and any
objects clear of the inboard edge of the platform. Your feet or objects on the platform can become
trapped between the platform and the Liftgate extension plate.
•Never perform unauthorized modifications on the Liftgate. Modifications may result in early failure
of the Liftgate and may create hazards for Liftgate operators and maintainers.
• Correctly stow platform when not in use. Extended platforms could create a hazard for
people and vehicles passing by.
WARNING
•Recommended practices for welding on steel parts are contained in the current AWS (American
Welding Society) D1.1 Structural Welding Code - Steel. Damage to Liftgate and/or vehicle, and
personal injury can result from welds that are done incorrectly.
!
WARNINGS
•Recommended practices for welding galvanized steel are contained in the current AWS (Ameri-
can Welding Society) D19.0 Welding Zinc-Coated Steel. Damage to Liftgate and/or vehicle, and
personal injury can result from welds that are done incorrectly.
Comply with the following WARNINGS and SAFETY INSTRUCTIONS while installing
Liftgates. See Operation Manual for operating safety requirements.
Installing and maintaining a liftgate can expose you to chemicals, including lead, which are known
to the State of California to cause cancer and birth defects or other reproductive harm. To mini-
mize exposure, install and maintain liftgate in a well-ventilated area and wear proper Personal
protective equipment (PPE). For more information go to www.P65Warnings.ca.gov.

NOTICE NOTICE
•Maxon Lift is responsible for the instructions to correctly install MAXON Liftgates on
trucks or trailers only.
•Liftgate installers, not Maxon Lift, are responsible for reviewing and complying with all
applicable Federal, State, and Local regulations pertaining to the trailer or truck.
SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
•Comply with all WARNING and instruction decals attached to the Liftgate.
•Keep decals clean and legible. If decals are illegible or missing, replace them. Free replacement
decals are available from Maxon Customer Service.
•Consider the safety and location of bystanders and location of nearby objects when operating the
Liftgate. Stand to one side of the platform while operating the Liftgate.
•Wear appropriate safety equipment such as protective eyeglasses, faceshield and clothing while
performing maintenance on the Liftgate and handling the battery. Debris from drilling and contact
with battery acid may injure unprotected eyes and skin.
•Do not allow untrained persons to operate the Liftgate.
•Be careful working by an automotive type battery. Make sure the work area is well ventilated and
there are no flames or sparks near the battery. Never lay objects on the battery that can short the
terminals together. If battery acid gets in your eyes, immediately seek first aid. If acid gets on your
skin, immediately wash it off with soap and water.
•If an emergency situation arises (vehicle or Liftgate) while operating the Liftgate, release the con-
trol switch to stop the Liftgate.
•Read and understand the instructions in this Installation Manual before installing Liftgate.
•Before operating the Liftgate, read and understand the operating instructions in Operation
Manual.
•A correctly installed Liftgate operates smoothly and reasonably quiet. The only noticeable noise
during operation comes from the power unit while the platform is raised and lowered. Listen for
scraping, grating and binding noises and correct the problem before continuing to operate Liftgate.
•Installers of the liftgate should ensure that all trucks and trailers are equipped with grab
handles as needed. Refer to Technology Maintenance Council (TMC) RP 1428: Entry
And Egress Guidelines for Vehicles With Fold-Under Type Liftgates.

VEHICLE REQUIREMENTS
Check for correct clearances (FIGS. 8-1 to 12-2) on vehicle to pre-
vent interference between vehicle and Liftgate.
NOTE: Make sure vehicle is parked on level ground while preparing vehicle and
installing Liftgate.
NOTE: BODY maximum and minimum operating bed height:
Maximum height is 53” (Unloaded). Minimum height is 46” (Loaded).
On vehicle bodies equipped with swing-open doors, the platform
may have to be modified to install this Liftgate.
NOTE: Dimensions are provided as reference for fitting Liftgate to vehicle body.
For detailed ground clearance information, refer to the WELD SIDE PLATE
procedure in this manual.
CAUTION
The sliding axle assembly on a trailer can collide with a Liftgate mounted
on the slide rails. To prevent damage to Liftgate and trailer, install stops on
the slide rails to keep the sliding axles from hitting Liftgate. Refer to Liftgate
clearance dimensions in this section of the manual.
