The person in charge must satisfy themselves weekly that there are no obvious operationally
dangerous defects and that the tasks listed in the chapter "Duties of the stairlift operator" are being
carried out carefully.
2.3 User group
The stairlift may only be used by competent, qualified and responsible persons who are familiar with
the system. The user must be able to take 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 stairlift 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 aggressive
media, etc.).
Outdoor use is possible in principle, however, in the case of outdoor installations that are exposed
to the weather, it may be necessary to clear parts of the installation of ice and snow in winter on a
case-by-case basis.
2.5 Qualified workers
Installation, maintenance, repairs and checks must be carried out by qualified persons, preferably by
companies authorised by Lehner Lifttechnik.
2.6 Decommissioning
When the unit is taken out of service for cleaning, maintenance or repair work, it must be protected

3TECHNICAL EQUIPMENT
The Alpha stairlift is designed to transport people with reduced mobility. It is driven by a rack and
pinion on the bottom rail. The lift is powered by 2 x 12 V batteries which are charged at the stops
(as long as the power supply unit is powered).
The standard version is supplied with a manually folding footboard as well as manual swivel seat.
The lift can be operated from 2 radio remote controls in the stops and from the control on the seat.

4SAFETY DEVICES
The Alpha stairlift is equipped with the following safety features:
4.1 Armrests
The armrests, which must be closed (horizontal) or folded up while driving empty, prevent falling
from the chair and act as support for getting in and out of the chair in the landings.
4.2 Contact bottom
The contact bottom is attached to the underside of the footrest and serves as an additional safety
feature. It reacts to pressure so that the system stops immediately if the footrest hits an obstacle.
The travel command in upward direction remains active.
4.3 Lateral covers on the drive and carriages
Contact-sensitive covers are fitted to the sides of the drive and the carriages, which prevent
jamming in the direction of travel. The travel command in the opposite direction remains active.
4.4 Emergency stop (optional)
The stairlift can be equipped with an emergency stop button. If you need to stop the stairlift in an
emergency, press the red button and the lift will stop. Unlocking is done by pressing it again or
turning it clockwise.
4.5 On/Off switch
The stairlift is fitted with an on/off switch. When the lift is not in use, this switch should be turned off.
4.6 Alarm button (optional)
The stairlift can be equipped with an alarm button to summon help. Pressing the alarm button will
sound a loud emergency signal.
4.7 Speed limiter and safety gear
The stairlift is equipped with a speed limiter and a safety gear. If the stairlift descends at an
increased speed (e.g. due to a defect or similar), the increased speed is immediately detected by
the overspeed governor and the safety gear is triggered. The safety gear brings the stairlift to a
stop by holding it against the rails. This prevents the stairlift from falling.

Alpha | User Manual Version 09/2022 Page 10
4.8 Battery charging system
The drive motor of your Alpha stairlift is powered by batteries which are charged via a charger.
Charging takes place at each stop via charging contacts. When the stairlift is not in use, it is therefore
necessary to always park the stairlift in the landing.
To prevent accidental parking outside a loading bay, an acoustic signal has been installed in the
stairlift:
4.8.1 The beeper
If the stairlift does not park exactly on the loading point after use, the lift will give a short
beep every second after 5 seconds. Then please move the lift to a stop (where it will also
stop automatically) and the beep will stop.
If the stairlift parks correctly in the charging position and the lift starts to beep briefly
every second, this means that the battery charging process has been interrupted. Turn
off the main switch on the stairlift (the lift will stop beeping) and check if there is a power
failure in your building or if the fuse or RCD in the stairlift power supply circuit is not in
order. Replace the fuse or switch on the RCD and then the main switch. 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. Drive the vehicle to the charging station,
where the batteries will recharge. If the lift beeps while driving even after charging the
batteries, the batteries are defective. The batteries must now be replaced by the service
department. If the stairlift continues to operate despite weak batteries, the stairlift control
is programmed so that the stairlift will definitely reach the lower landing with the
remaining battery voltage.

5OPERATING ELEMENTS
5.1 The main power switch
The main power switch connects the system to the mains. It is located at
the front of the drive.
The main power switch must be switched on so that the system can be
operated. With this switch, the power can be switched off on the entire
system and the control unit.
5.2 Operating elements
The chair lift is operated by the joystick in the armrest or by the up and down buttons of the call

6.1 Automatic footrest function
If the lift is equipped with an optional automatic footrest folding,
you can unfold the footrest comfortably before or after being
seated. The footrest movement is activated by pressing of the
button on the side of the armrest.
If you choose to first sit down, open your legs about 30cm when
sitting on the chair and press the button on the side of the
armrest. The footrest will now fold down automatically.
When you exit the seat, you can comfortably fold up the footrest
by pressing again the button on the side of the armrest.
6.2 Calling and sending the stairlift
1) Make sure that no one is using the lift and no one is on the stairs.
2) Now you can call or send the lift with the up or down button on the call stations.
3) The chairlift runs as long as the drive command button is pressed and stops automatically
at the stop.
Call stations are supplied with 2 x 1.5V AAA batteries. The service life of the batteries is approx. 1
year. The batteries can be replaced during the annual maintenance.
If the green LED light stops flashing when the buttons are pressed, the batteries must be changed.

6.3 Rotating the seat with a manual swivel seat
On the upper landing, the seat can be manually rotated (swivelled) into different positions for easier
entry or exit.
1) Push the lever down. The levers are located on the side of the chair, behind the armrest
supports.
2) Turn the seat in the direction of the exit
3) There are 5 different positions at 0°, 20°, 45°, 70° and 90° rotation. At the desired rotation,
pull the lever back up and make sure that the lever snaps back into place and fixes the seat
in this position!
4) Leave the chair.
5) Turn the seat back to the driving position and pull the lever firmly upwards so that it
engages again.
6) If desired, you can now fold up the footrest and the armrests and park the lift in this way.
7) Remove the key (optional) from the armrest to prevent unauthorised persons or children
from using the lift.
8) The platform must be folded to release the lift for other users. Thus, the call stations become
active again and the lift can be sent or called to a desired location.
Always make sure that the lever is in locked position (pulled downwards) after swivelling,
especially when the lift is parked.

Alpha | User Manual Version 09/2022 Page 15
6.4 Rotating the seat with the automatic swivel seat
In the case of an automatic swivel seat, the call stations are equipped with 2 additional buttons that
allow the seat to be swivelled automatically on an intermediate or the upper landing.

short delay, the seat will start to turn automatically. Wait until the seat has turned
completely and stops.
2) Leave the seat.
3) Turn the seat back by pressing the button on the call station.
4) Now you can fold up the seat, footrest and armrests.
6.5 Passing through an intermediate stop with automatic swivel seat
If you do not want the seat to start turning in an intermediate landing, release the joystick briefly as
soon as the seat stops in the intermediate landing stop. Now you can press the joystick again and
the lift will continue in the desired direction.
7FOLDING RAIL
If the unit is equipped with a folding rail, please read the following points carefully:
▪Before the folding rail can be used, the key switch on the control station must be in the
"ON" position
▪The folding rail can be operated by means of a joystick on the armrest or with the
additional remote control supplied for the folding rail.
7.1 Journey from the lower to the upper stop
▪If you want to move from the lower to the upper landing, the lift stops automatically at the
loading station, which is installed after the folding rail. Now press and hold the joystick
upwards so that the rail folds in completely and the lift can continue to move upwards.
▪The stairlift can also be manoeuvred by remote control. To do this, press the "Drive up"
button. The lift then stops after the folding rail at the loading station. Now activate the folding
of the rail by pressing the "Fold" button on the additional remote control of the folding rail.
After it has been folded, you can now park the stairlift at the charging station or continue
the journey to the upper stop without any problems.
7.2 Journey from the upper to the lower stop
▪If you want to move from the upper to the lower stop, press the joystick down. The lift stops
automatically on the loading station in front of the folding rail. Now keep the joystick pressed
down so that the rail opens, and the lift moves to the lower landing.
▪The stairlift is located in the upper landing and is called down with the remote control. At
the loading station in front of the folding rail, it stops automatically. Now press the "Unfold"
button on the additional remote control of the folding rail until it is fully opened. The ride
down to the lower stop works with the operation for the lift, to do this, keep the "Ride down"
button pressed.
