1INTRODUCTION
We would like to congratulate you on the purchase of a stair lift from Lehner Lifttechnik GmbH
and welcome you to our large circle of satisfied customers. For more than 30 years, our lifts have
been known as reliable means of transport, which are characterised by individual adaptation to
structural conditions.
The Alpha stairlift represents a new generation of seated stairlifts with proven technology. The lift
has been built according to the currently valid European safety rules.
As with any appliance that operates under load and whose parts are in motion, the
utmost attention is required. Please read this user manual carefully. Make sure that every
user of the lift has read and understood the user manual before using the lift. You will
find instructions for operating the unit as well as safety instructions.
Use these instructions to benefit from Lehner Lifttechnik's many years of experience in the
operation of stairlifts. Proper care of the system on your part as well as scheduled maintenance by
a competent company will provide you with a reliable lift system over a long period of time.
Lehner Lifttechnik GmbH and its authorised partner companies offer you a comprehensive
maintenance programme specifically for your installation, precisely adapted to its operation. Take
advantage of the manufacturer's experience to achieve the highest possible efficiency for your
stairlift system.
Keep these operating instructions for future reference.
Lehner Lifttechnik GmbH expressly disclaims any liability for breakdowns caused by disregard of
these instructions, non-compliance with the safety instructions or incorrect handling.
We hope you enjoy using the Alpha stairlift!

2.2 Operator of the stairlift
At least one responsible person must be appointed for each stair lift; this person must be easily
accessible during the operating time of the installation. The installation must be maintained in a safe
condition. If the installation is found to be unsafe, it must be taken out of service immediately; danger
points must be secured. Accidents must be reported immediately to the expert (lift inspector or
installation company) or the manufacturer.
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
against unintentional movement. The key switches on the call stations must be switched off and the
keys removed.

2.7 Intended use
Preventive checks and regular maintenance of the system are highly recommended and guarantee
you long-term, safe functioning.
2.7.1 Safety instructions
Observe the following points for correct use:
▪The stairlift is designed exclusively for transporting one person seated on the seat
provided.
▪Never ride standing on the seat (risk of injury to the head, risk of falling).
▪The stair lift is not intended for load transport.
▪Always lock the stairlift so that it cannot be operated by unauthorised persons (e.g.
children playing).
▪Adhere to the specified maximum loads.
▪The system must be maintained and safety-checked at the prescribed intervals.
▪Passers-by going up or down the stairs must avoid any contact with the stairlift.
Stairlift users must always be aware of pedestrians or other obstacles.
▪Do not use the stairlift in case of fire! There could be a power failure during the ride
and the user would be trapped.
▪Never exceed the permissible payload! The payload is indicated on the type plate.
▪Never bring your hands or loose clothing near the track or the back of the stairlift
when the lift is in motion. Passengers must remain in the seat throughout the ride.
▪Do not open the armrests while driving or outside of landings.
▪Do not activate the manual swivel lever for turning the seat during driving or outside
of landings.
▪Do not disable any safety device by making mechanical or electrical changes to the
installation. Without the written consent of Lehner Lifttechnik, all types of adjustments
and/or modifications to the system are prohibited
▪The stair lift may only be used by one person at a time. Accompanying persons are
not allowed on the stair lift under any circumstances. Otherwise there is a risk of
falling.

2.7.2 Use of the stairlift
The stairlift may only be used if it is in technically perfect condition. Any malfunction that could affect
safety must be avoided or eliminated.
Report anything unusual to your service engineer. Do not use the stairlift if there are any irregularities
or unusual noises - call the service immediately. All instructions and advice from experts, fitters and
service personnel must be followed.
Before entering the up or down command, make sure that no one is endangered by the
movement of the system. Always look in the direction of travel!
The transport of goods is only permitted if sufficient stability is ensured so that they cannot slip or
fall over.
Also, keep the keys in a safe place and do not give them to unauthorised persons. Do not leave the
keys on the vehicle or at the call stations when the lift is not in use.
In the user video of our Alpha stairlift
we show you the correct use of your lift.

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.
