were removed. New bilingual decals P/N 299038-01 were added.

Comply with the following WARNINGS and SAFETY INSTRUCTIONS while installing
Liftgates. See Operation Manual for operating safety requirements.

WARNINGS

• Do not stand, or allow obstructions, under the platform when lowering the Liftgate. Be sure your
feet are clear of the Liftgate.

• Keep fi ngers, hands, arms, legs, and feet clear of moving Liftgate parts (and platform
edges) when operating the Liftgate.

• Correctly stow platform when not in use. Extended platforms could create a hazard for
people and vehicles passing by.

• 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 modifi cations on the Liftgate. Modifi cations may result in early failure

of the Liftgate and may create hazards for Liftgate operators and maintainers.

• 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.

!

WARNING

• Recommended practices for welding galvanized steel are contained in the current AWS (Ameri­can 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.

SAFETY INSTRUCTIONS

• 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.

• 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.

• Do not allow untrained persons to operate 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.

• Be careful working by an automotive type battery. Make sure the work area is well ventilated and

there are no fl ames 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 fi rst 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.

SAFETY INSTRUCTIONS

• 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.

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.

• 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.

STANDARD LIFTGATE COMPONENTS

!

CAUTION

Unpacking the Liftgate on unlevel surface may allow heavy components to slide off
when shipping bands are cut. Injury and equipment damage could result. Before
the shipping bands are cut, put Liftgate on level asphalt, concrete or compacted
dirt surface that will support 1500 lb. When unpacking the Liftgate, remove heavy
components carefully to avoid injury and damage.

NOTE: Make sure you have all components and parts before you start installing Liftgate.

Compare parts in the part box and each kit box with packing list enclosed in each
box. If parts and components are missing or incorrect, call:

CAUTION

• To prevent platform from being damaged, make sure vehicle frame is cut cor­rectly. If the cutouts are incorrect, platform may hit vehicle frame or underbody
when stowing the Liftgate.

• Installer is responsible for ensuring that vehicle body and frame modifi cations
do not adversely affect the integrity of the body and frame.

NOTE: The dimensions, shown in the illustration below, are maximums except as

indicated.

NOTE: The platform cutout area shown below applies to trucks. If the rear sill di-

mension is taller than 5” it may need to be modifi ed. Check with body man-
ufacturer before modifying the rear sill.

STEP 1 - ATTACH EXTENSION PLATE TO VEHICLE

CAUTION

CAUTION

To preserve the corrosion-resistant properties of the galvanized fi nish,
MAXON recommends bolting the galvanized extension plate to vehicle.

NOTE: TE-25DC & TE-33 Liftgate extension plate comes with bolt holes so it can

be bolted to vehicle body with optional bolt kit. GRADE 8 bolts are re­quired. MAXON recommends getting the optional extension plate hardware

kit listed in OPTIONS section. Vehicle body must be drilled according to

instructions. Extension plate may also be welded to vehicle body. Do the fol­lowing bolting or welding instructions for the extension plate.

CAUTION

CAUTION

The mating surface between the bolt-on extension plate and vehicle rear sill
must be as fl at as possible. Interference between the mating surfaces could
result in a distorted top surface of extension plate when all the bolts are
tightened. Distorted extension plate can also make the dual steps diffi cult to
install correctly. Remove interference or shim rear sill to eliminate or reduce
the possibility of a distorted extension plate.

NOTE: Do not tighten extension plate bolts and lock nuts until:

• All the bolts and lock nuts are in place.

• Mating surfaces of extension plate and rear sill are made fl at as possible.

• Top of extension plate is fl ush with top of rear sill.

NOTE: Weld the LH and RH ends of the extension plate to vehicle body as shown

in FIG. 19-1 if any of the following conditions apply.

• Bolt holes are not accessible on the corner posts of the vehicle body.

• Liftgate will be used for dock loading applications.

• As required by body/trailer manufacturer

2. Bolt extension plate to vehicle as shown in FIG. 19-1. If necessary, reposition extension

plate so top surface is fl ush with top surface of sill. Then, torque bolts and lock nuts to

105 +/-20 lb-ft.

CAUTION

To preserve the corrosion-resistant properties of the galvanized fi nish,
MAXON recommends bolting the galvanized extension plate to vehicle.

CAUTION

To protect the original paint system if equipped, a 3” wide area of paint must
be removed from all sides of the weld area before welding.

NOTE: Before welding extension plate to vehicle body, make sure:

• Inboard edge of extension plate is fl ush with the top of sill on vehicle body.

• Top surface of extension plate is level with the ground.

NOTE: For welding galvanized steel, refer to recommended practices as outlined in

AWS (American Welding Society) D19.0 Welding Zinc-Coated Steel.

1. Center the extension plate on vehicle body. Before welding extension plate to vehicle

body, make sure top surface of extension plate is fl ush with fl oor of vehicle body.

Weld the extension plate to vehicle body sill as shown in FIGS. 20-1 and 21-1.

CAUTION

To prevent damage to the fl ipover, NEVER hoist the Liftgate by the

as shown in the YES illustration.

2. Make sure hoist

is not being set
up the incorrect

way (FIG. 24-2).

Place a “C”­clamp on each
side of platform

as shown in FIG.
24-1. (Clamps prevent

hoist chain from slipping off
platform.) Place chain all
