Important Notes
1.1 Attention
Before starting any operations of the liftgate, please read and understand this OWNER’S MANUAL. Its
intention is to act as a guide for the operation personal as well as to give help with preventive maintenance but
does not take place of unauthorized usage or repair by unqualified personnel.
Please contact your nearest PALFINGER Liftgates distributor or PALFINGER Liftgates in California or New
Jersey for assistance if you have questions regarding installation, operation or maintenance.
This owner’s manual applies to the following models: ILSL Slide Units 30, 40
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid possible injury.
1.2 Important Notes
The PALFINGER Liftgates ILSL model is an electro-hydraulically driven lift gate, designed to be stored
underneath the truck or trailer for ultimate dock loading as well as offering up to 6-1/2 feet platform.
The Hydraulic Power Unit (HPU) is easily accessible for service and exchange. The whole assembly slides out
and can be serviced at that point. To exchange the Hydraulic Power Unit (HPU), two hoses and the battery
cables need to be disconnected.
The platform folded in half is supported by two torsion springs, each on one side, one support folding the other
unfolding operation. The platform in a stored position acts as the under ride guard. Lifting actions are carried
out by hydraulic cylinders mounted on the lift arms.
The gate is equipped with swing fixtures mounted to the bottom on each lift cylinder. This enables the platform
to lower down the tip towards the ground.
The hydraulic cylinders are equipped with solenoid operated valves located at the port of each cylinder which
prevents the platform from lowering accidently unless the operator is activating the controls. This system also
enables you to store the lift gate without a separate platform latch.
The piston rods are treated against corrosion. The HPU is equipped with a built-in pressure relief valve, which
prevents overloading when lifting.
The valves do not prevent overloading of the platform when lowering or tilting down.

The electric supply is taken from the vehicle battery. If the vehicle battery is not sufficient or not existing (like
on trailer units), an auxiliary battery kit needs to be installed. The electric control power is protected via a 20
Amp fuse and an on-off switch. The switch has L.E.D. lights indicating when the control power is on. (Trailer
application has an on-off switch located in the lockable control box or at the auxiliary battery box).
The liftgate is operated from an outside control box which is located on the curbside of body. Foot controls are
optional, which enables the operator to handle the cargo and operate the lift by foot. A variety of different
product options can be purchased with the PALFINGER Liftgate as well.
1.3 General Information
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 the 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.
In the interest of safety it is important that all operating personnel properly understand the functions of
the lift gate, possible hazards, dangers, the load limits and load positioning for that specific unit.
IMPORTANT NOTICE!
Before the operator uses the lift gate, 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 inspect this lift for maintenance or damage before using it. 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.
The maximum loads must be observed and followed!
IMPROPER USE
It is not permitted to use the tail lift:
•As an elevating work platform
•To push loads
•To carry people (Only the operator may travel on the platform)
•To clear snow
Please read through the operational and technical description of this PALFINGER Liftgate.
Thank you for choosing PALFINGER Liftgates.
