CAUTION

Anthony Liftgates 

recommends not 

riding the liftgate; 

however, if the operation requires it, make sure your 

footing is stable before raising or lowering the 

platform.  Always stand away from the edge.  When on 

the ground, always stand clear of the liftgate when it 

is operating.

Do not attempt to maintain the liftgate 

under the influence of drugs or alcohol. 

Consult your doctor before using the 

liftgate while taking prescription medications.

To prevent personal injury, clean up any 

spilled fluids immediately. To avoid 

tripping, do not leave tools or 

components laying around in the work area.

Failure to prevent the truck from moving 

during the maintenance of the liftgate 

could result in a serious crushing injury.
Always use/set the truck’s parking brake 

and remove the ignition key before 

servicing the liftgate. Failure to follow 

this recommendation can result in injury.

 

Do not place hands or feet in pinch points.    

Do not place your feet under the liftgate or 

between the platform and floor extension. 

 

To prevent injury, the liftgate and its related 

components should only be maintained by a 

qualified installer having knowledge and skill in 

using a lifting device, a cutting torch, and welding 

equipment.

N ING

AR

To prevent possible injuries due to improper 

operation, make sure all decals are attached to 

the liftgate and/or truck and are legible at all 

times.
2.3.2  Equipment / Tools / Parts

CAUTION

Do not operate this unit if 

it is damaged. If you 

believe the unit has a 

defect, which could cause it to work improperly, 

you should immediately stop and remedy the 

problem before continuing.

Make sure the liftgate or truck will not be 

damaged or made unsafe by the maintenance 

or use of the liftgate.
Never secure the power cable to anything 

which allows it to contact sharp edges, other 

wiring, fuel tank, fuel lines, brake lines, air 

lines, exhaust system, or any other object that could 

cause the power cable to wear or be damaged.  A cut 

battery cable can cause sparks and/or component 

damage resulting in loss of vehicle control, serious 

injury, or even death.

CAUTION

OEM

 If replacement parts are 

necessary, genuine 

factory OEM replacement 

parts must be used to restore the liftgate to the 

original specifications. Anthony Liftgates will not 

accept responsibility for damages as a result of using 

unapproved parts. If non-OEM replacement parts are 

used, the warranty will be voided.
2.3.3  Battery / Fuel Tank Safety

WARNING

To prevent 

s e r i o u s 

bodily injury, 

keep sparks, lighted matches, and open flames away 

from the top of the battery because battery gas can 

explode.  Always follow all the manufacturers’ safety 

recommendations when working around the truck’s 

battery.

Take precautions to avoid sparks coming into 

contact with the truck’s fuel tank, brake lines, 

or other flammable components.  Sparks can 

cause an explosion of combustible materials, resulting 

in serious injury or death. 
2.3.4  Cutting Torch / Welding Safety

WARNING

Take precautions to avoid 

sparks from contacting 

 

the truck’s fuel tank, brake 

lines, or other flammable components.  Sparks can 

ignite combustible materials, resulting in serious 

injury or death. 

Always weld or use a cutting 

torch in a well-ventilated area 

and, if in an enclosed area, vent 

the fumes to the outside.  Breathing welding smoke 

and paint fumes can cause serious injury. 

Always follow all State and Federal health and 

safety laws and/or local regulations when using 

an arc welder, mig welder, or cutting torch.  Also, 

follow all manufacturers’ safety guidelines.  If other 

people are present during the installation of the liftgate, 

make sure the assembly area is shielded from their view.  

To avoid eye injury during welding, always 

wear a welding helmet with the proper lens to 

protect your eyes.
To avoid eye injury while using a cutting torch, 

always use eye protection with the proper lens 

to protect your eyes.

 

SAFETY

 INSTRUCTIONS

Do not modify safety 

devices. Do not 

weld on the liftgate 

assembly, except the adapter frame tube.  Unauthorized 

modifications may impair its function and safety.

Make sure all parts are in good working 

condition and properly installed. Replace any 

damaged parts immediately.
