2.2 Platform lift operator
At least one responsible person must be appointed for each platform lift; this person must be
easily reachable during the operating time of the installation. The installation must be maintained
in a safe condition. If the system is found to be unsafe, it must be taken out of service immediately;
danger zones must be secured. Accidents must be reported immediately to the expert (lift
inspector or installation company) or the manufacturer.
The person in charge must make sure on a weekly basis that there are no obviously dangerous
operational defects and that the tasks listed in the chapter "Duties of the platform lift operator" are
being carried out carefully.
2.3 User group
The platform lift may only be used by competent, qualified and responsible persons who are
familiar with the system. The user must be able to assume responsibility for himself and for third
parties.
Persons who do not meet these requirements, as well as children, may only be transported by
accompanying persons who also assume responsibility for the person being transported.
2.4 Range of application
The platform lift may only be used on stairs or accessible ramps. It is recommended to install the
system in predominantly dry rooms. The ambient temperature must not be below -15 °C or above
+ 40°C. This type is not suitable for use in unusual locations (e.g. explosive areas, areas with

4 SAFETY DEVICES
The platform lift is equipped with the following safety device:
4.1 Access ramp or travelling platform door
The ramp, which must be folded up during the journey, or the platform door prevent a fall in
longitudinal direction. This always opens/unlocks automatically in the lower stop as long as the
drive command is held down.
4.2 Safety curtain
The safety curtain is fitted around the platform mechanics and serves as an intervention protection.
4.3 Contact bars
Contact bars can be fitted to the side of the platform floor to prevent jamming in the downward
direction of travel when the system is mounted in a pit. The travel command in the opposite
direction remains active.
A contact bar along the sliding wall prevents jamming in the upward travel direction. The travel
command downwards remains active.
4.4 Overload device
The platform is equipped with an overload device in upward travel. If the load capacity indicated
on the type plate is exceeded by more than 75 kg, an overload switch switches off the system and
an acoustic signal sounds as well as the overload indicator on the platform. In this condition, it is
not possible to drive off.
The platform must never be overloaded. If an overload is signalled, the loading must be
reduced immediately.
4.5 Emergency stop
The Liftboy platform lift is equipped with an emergency stop button. If you need to stop the
platform in an emergency, press the red button and the lift stops. Unlocking is done by pressing it
again or turning it clockwise.
4.6 Alarm button
The platform is equipped with an alarm button to summon help. By pressing the alarm button, a
loud emergency signal sounds.

Liftboy 5 | User Manual Version 07/2023 Page 10
4.7 Battery charging system
The drive motor of your platform lift is powered by batteries which are charged via a charger. The
charging is permanent.
If the platform lift is not charged, the lift will emit a short beep every second after 5
seconds. Check that the lift or the charger is connected to the mains. Turn off the main
switch on the back of the platform (the lift will stop beeping) and check if there is a
power failure in your building or if the fuse or RCD in the power supply circuit is not in
order. Replace the fuse or switch on the RCD and then the main switch at the rear of
the platform. If the lift continues to beep, please call the service department, it could be
that the battery charger is faulty.
If the battery voltage for the travel drive of the lift becomes too low, a long beep sounds
every 2.5 seconds while the lift is travelling. If the charger is connected and the lift still
beeps during travel even after charging the batteries, the batteries are defective. The
batteries must now be replaced by the service department. If the platform lift continues
to operate despite weak batteries, the control is programmed so that the platform will
reach the lower landing in any case with the remaining battery voltage.

Liftboy 5 | User Manual Version 07/2023 Page 11
5 OPERATING ELEMENTS
5.1 Controls on the platform
The platform is equipped with a control column as standard. On it are the travel buttons, an
emergency stop, an alarm button, a key switch and a display.

Liftboy 5 | User Manual Version 07/2023 Page 13
5.3 Call stations at the landings
The platform lift is equipped with radio call stations with a key switch as standard. With these call
stations, the platform can be called from one landing or sent to another landing. The call station
must be activated with the key switch before operation.
The control stations are used for calling and sending, as well as for opening and closing the ramp /
swing door. A green light flashes when the radio signal is working. The call stations are supplied
with voltage by a 9V battery as standard. The battery life is approx. 1 year.
The status of the radio station can be read from the LED:

When the platform has entered the landing, the swing door opens automatically. Please note that
you are not in the door's turning range while it is opening.
When the door is opened, the control commands of the call stations are automatically cancelled so
that the lift cannot be operated by another person at the same time and safe travel on the
platform is guaranteed. You can now drive onto the platform.
The automatic swing door closes again automatically after an opening time set during installation.
Please ensure that you are not within the door's turning range when it is closing.
If an acoustic signal sounds when driving on the platform, the platform is overloaded
and must be unloaded again immediately.
6.3 Driving with the platform
On the platform there is a key switch, the travel command buttons, an alarm button and an
emergency stop button.
The wheelchair must be secured against rolling away on the platform by a parking

Hold on to the handrail!
The travel command is given by pressing the travel command for the desired direction. Keep the
travel command pressed until you reach the desired stop.
If you release the drive command while driving, the platform stops immediately. If the platform
does not stop when the drive command is released, an emergency stop (red button) has been
installed for additional safety. If this emergency stop is pressed, the system stops immediately. The
emergency stop button is unlocked again by pressing it again or turning it clockwise.
6.4 Leaving the platform
The lift is designed so that the platform stops in the right place in the stops. After the platform has
stopped in the desired stop, you can release the travel command.
Manual swing door
Open the swing door manually again. You can now leave the platform. After leaving the platform,
the manual swing door must be closed so that the call stations become active again. The platform
can now be called to a desired location or used by another person.
