General
You have chosen a lift gate of the highest quality. The lift gate is a low maintenance unit. It is
equipped with maintenance-free, grease-free bearings and does not require greasing
throughout its entire lifetime.
The lift gate may only be used for the raising and lowering of loads, which must be loaded in
accordance with the load diagram.
The lift may be operated, maintained and serviced only by persons who have received
appropriate training and who have been specifically instructed of the dangers associated with
its operation.
The accident prevention regulations, must be observed. If they are not, the manufacturer
cannot accept any liability for resultant damage or injury.
These operating instructions are valid for following lift gates :

•Legibility of all operating and information labels
•Check for weld cracks and make sure all bolts and nuts are tight

The driver should report any incorrect operation or obvious damage
to his maintenance department. All damages are to be mended
immediately. The lift gate owner is responsible for the repairs of
detected damages.
The operating instructions are to be carried in the vehicle at all
times.

results of this verification must be written down in the maintenance book.

Battery size Group 31
For use in short-haul traffic the next step up should always be selected.
Heavy-duty alternators are strongly recommended.
The operator is resp onsible for the battery capacity and the c harge status of the
battery.
The electric motor
You can avoid damages to the motor or the power relais if you ensure that you have the right
voltage at all times. If the motor has trouble with a load that is normally lifted without a
problem, stop the lifting operation immediately and charge the batteries.
If, in your opinion, the batteries are empty too fast, have the batteries and the power cables
checked by a specialist.It could be possible that the cables, the mass connection or the
batteries have to be repaired or changed.

General Information
Standing on the platform when it is moving
As it is only allowed for the operator to stand on the platform, he must ensure that no other
person (especially children) are standing inside the danger zone.
Hazard information for unsecured loads
Under certain circumstances, there is a possibility that the front axle of the vehicle lifts while
unloading. On this inclination, unsecure loads may start to slip and create a danger for the
operator.
You can purchase a warning sticker
CAUTION ! Secure the load against
moving or use mechanical supports

Description of the Safety Installations
Hose Rupture Valves
If a hose, a pipe or a screw connection should burst, the lift gate lowers or inclines in a
controlled manner at the permitted speed, as long as a function is connected via one of the
control units (hand held remote controls, foot controls or hand control box). If such control
unit is not activated, or ceases to be activated, the lift gate stops automatically.
Safety Valve
The lift gate is protected by the factory-set safety valve from raising loads which are heavier
than the specified carrying capacity. This valve may only be adjusted by an expert using a
test weight and a manometer.
Fuses
Defective fuses may only be replaced by fuses which correspond to the values specified in
the wiring diagram and on the distributor plate. Larger fuses may not be blown in the event of
malfunctions, which could lead to cables catching fire.
Roll-off Safety Devices
If roller containers are being used, the lift gate should be equipped with roll-off safety
devices. Their operation is impaired by dirt; the operator should keep the roll-off safety
devices clean at all times.
Warning Flags
The flags can be seen until the platform is on the ground. Both safety installations should be
kept clean and in perfect condition at all times.
(Optional version)
Warning Lights
The lights flash as soon as the platform has opened a few degrees.
