2.1 General Safety

REMEMBER!

It is the fleet manager’s responsibility to educate the operator on the liftgate and its intended use. The

operator’s attention should be drawn to the permitted load limits and an understanding of the operation to

ensure safety throughout the operation.

ONE-MAN OPERATION!

Never let an “outsider” operate the liftgate while you are handling the cargo. A “misunderstanding” can
result in serious personal injury or even death.

In the interest of safety it is important that all operating personnel properly understand the functions
of the liftgate, possible hazards, dangers, the load limits and load positioning for that specific unit.

IMPORTANT NOTICE!

Before the operator uses the liftgate, they should be thoroughly familiar with the lift’s functions and
usage according to the following:

1. Improper operation of this lift can result in serious personal injury. Do not operate unless you have
been properly instructed, have read and are familiar with the operation instructions. If you do not
have a copy of the instructions please obtain them from your employer, distributor or lessor, as
appropriate, before you attempt to operate the lift.

2. Be certain the vehicle is properly and securely stopped before using the lift.

3. Always maintain the liftgate and inspect it for damage before usage. If there are signs of improper
maintenance, damage to vital parts, or slippery platform surface, do not use the lift. Do not attempt
your own repairs unless you are specifically trained.

4. Do not overload. See the Rating Label on the unit for the rated load. Remember that this limit
applies to both raising and lowering operations.

5. Each load should be placed in a stable position as near as possible to the body of the truck/trailer.

6. Never stand in, move through or allow anyone else to stand in or move through the area in which the
lift operates, including that area in which a load might fall.

7. This is not a passenger lift. Do not ride the lift with unstable loads or in such a manner that a failure
would endanger you. The lift is not equipped with a back-up system to prevent falling cargo in the
event of a failure.

ILP 25/33 Owner’s Manual

Rev.1.4 8

Improper operation of this liftgate may result in severe personal injury or death. DO NOT operate unless
you have been properly instructed, have read and are familiar with the procedures in this manual. We have
designed this manual to illustrate the steps needed for the basic operation of this ILR+ liftgate. It also
provides safety information and simple preventive maintenance tips.

3 Important Information

Before Getting Started

“READ FIRST”

Before starting any operations of the liftgate, please read and understand this Owner’s Manual. The

intention of this manual is to provide the user a guide for the operation as well as preventive
maintenance. Do not attempt to modify or repair the liftgate unless performed by qualified
personnel. Please contact your nearest Palfinger Liftgates distributor or Palfinger Liftgates in
California or New Jersey for assistance if you have any questions regarding installation, operation
or maintenance at 888-774-5844.

This owner’s manual applies to the following models: ILP 25 / 33

Important notes
The electric supply is taken from the vehicle battery. If the vehicle battery is not sufficient, an auxiliary

battery kit needs to be installed. The electric control power is secured via a 15-Amp fuse and an on-off
switch located inside the cab.

Trailer applications have an on/off switch near the rear curb side corner post.
The liftgate is operated from a standard toggle switch. A hand held remote control is optional with up and
down functions. A variety of different control options can be purchased with the Palfinger Liftgates product.

The valves do not prevent overloading of the platform when lowering or tilting down.

This manual is not intended for use as a repair or troubleshooting guide. Repairs should be
performed by a Palfinger Liftgates Authorized Service Center.

This Manual has been designed for use in conjunction with the ILP series liftgates only which are designed
for different capacities. There are four options available to determine the model and serial number of the
installed liftgate:

5 Maximum Load and Placing of Load on Platform

Every Palfinger Liftgate is rated up to a maximum load. The point of maximum load is rated at a defined
distance. The center point of maximum load is at 24” from the rear of the bed extension out to the platform,
