Important Notes
3.1 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: Minifix 500
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.
3.2 Important Notes
Your PALFINGER Liftgates Minifix is a cargo van lift design, electro-hydraulically driven lift gate.
The Hydraulic Power Unit (HPU) is easily accessible for service and exchange and is placed in a box
underneath the Truck.
Lifting actions are carried out by one hydraulic lift cylinder mounted to the lift arm.
The hydraulic tilt cylinder under the platform is controlling the tilting action. This enables the platform to
maintain its position throughout the lift mode, regardless of the terrain.
The hydraulic cylinders are equipped with solenoid operated valves located at the port of each cylinder. This
prevents the platform from moving 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 and also protected with plastic or rubber boots to protect from
road gravel and dirt. The Hydraulic Power Unit is equipped with a built-in pressure relief valve, which
prevents overloading when lifting and tilting up.
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, an auxiliary
battery kit needs to be installed. The electric control power is secured via a 20 Amp fuse and an on-off
switch located inside the cab. The switch has L.E.D. lights indicating when the control power is on.
The liftgate is operated from a 3-button outside control which is located on the curbside of your truck.
A standard 2-button hand held remote control is also supplied with the lift. A variety of different control
options can be purchased with the PALFINGER Liftgates product.

3.3 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 liftgate, possible hazards and dangers and 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 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.
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.
