ATTENTION -SAFETY FIRST
Please pay careful attention to the next points/instructions!
User group:
Only specially instructed persons are to use the OMEGA stairlift and must take
responsibility for all others who are present.
Users who are not able to fulfil these requests, as well as children, need an attendant
person who takes responsibility over the user.
Setup area:
OMEGA lifts can be mounted on staircases and ramps. The lift, however, is not
designed for use in unusual areas (like areas in danger of explosion, areas surrounded
by aggressive chemical substances, …). Outdoor use is possible, but the parts must
remain clear of ice and snow in winter.
Keys:
Keys should be kept in a safe place, away from those who are not to use the lift.
Remove the key from the control when not in use.
Provision application
èOMEGA stairlifts must only be used for the transport of persons in wheelchairs or
sitting on the fold down seat.
èNever use the stairlift in the standing position.
èOMEGA stairlifts must not be used for freight transportation.
èLock both the lift and the platform after use. Do not let children play on the lift.
èDo not exceed the maximum platform load or maximum wheelchair size.
èPay attention to the instructions provided on the lift.
èPay attention to the following points for the correct use of the stairlift.

USER HANDBOOK

Load capacity:
The maximum load is indicated on the sideboard of the carriage.
Serial load: 150 kg (330 lb) for the wheelchair platform
130 kg (286 lb) for seat performance.
(Optionally a plant with a maximum load up to 225 kg is available).
Do not exceed this limit!
Keep hands and fingers away from the back of the carriage! Passengers must remain
in the wheelchair or seat while the lift is operating.
Persons walking up or down the stairs while the lift is being operated must avoid
contact with the platform. Platform users should take into consideration that the platform
needs more space in a bend than on a straight railway. Therefore, before moving, look
to see if anyone is using the stairs or if there are any obstacles.
Emergency stop
An emergency stop is fitted on the carriage. In case of emergency press the red STOP-
switch and the lift will stop immediately. To unclamp the STOP-switch, it is necessary to
press it once more or to turn it clockwise.
OMEGA stairlifts are equipped with the following safety features:
-drive with self-locking gear and break
-overspeed governor
-mechanical bolted barriers
-optional: safety pads around the platform used for carriages without ramps
safety pads on the underside of the platform
Do not disable any safety feature of the lift by modifying mechanical or electrical parts
of the lift. Please contact LEHNER or one of its authorised partners for service!
We recommend preventive checks, i.e. a regular servicing of the OMEGA stairlift will
insure safe operation for a long time. Any abnormal operation of the lift should be
reported to the servicing engineer. In the case of irregularities such as vibrations or
abnormal noise emissions, do not use the lift. Call LEHNER for help! Follow all
instructions given by LEHNER experts, fitting teams and service staff.
Lift up the upper armrest before moving onto the platform or leaving the platform when
using a carriage with seat performance!

OPERATION
General
OMEGA lifts are safe and easy to use. The technical control of the lift is entirely adapted to
the abilities of physically handicapped persons.
Please refer to the general layouts on the previous pages for a better understanding of the lift.
Main power switch
The main power switch connects the plant to the power supply system. For use of the lift, first
turn on the main power switch. By switching off the main power switch, the whole plant can be
divided from the circuit.
It is necessary to switch off the main power switch while repairs are done to the stairlift,
especially in the drive box. The main power switch can be locked in both the “on” and “off”
position with a padlock.
The main power switch is located either on the side of the drive box (drive type K) or on the
external control box (drive type S).
Before operating the lift, ensure that the platform area is clear.

TROUBLESHOOTING
For safety reasons, the OMEGA stairlift is equipped with several electrical and mechanical
locking devices. The stairlift will not work if any of these devices are tripped or if the order of
events is incorrect. By following the instructions provided in the ensuing paragraphs, the user
will be able to determine the reason for breakdown. Contact our service team! You must not
manipulate, modify or remove any safety feature of the stairlift.
Work through the following instructions paragraph-by-paragraph. Do not skip any part! Be
sure that the landing controls are deactivated whenever the platform is folded down.
Before troubleshooting, pay attention to the following:
When a landing control is activated, it automatically deactivates all other wall controls,
i.e., the complete lift can only be controlled by one control at a time.
Please check if the main power switch, located either at the side of the drive box (Type
K)or on the top of the separate control box (Type S), is switched on (position I).
Please check if the fuses in the distribution box of your house are working and turned
on.
Check the electric fuse
Turn off the stairlift by switching off the main power switch. Open the front door
of the drive box* and dismantle the plastic cover of the control box (there is no plastic
cover for drive type S*). Check if the fuses F1–F2 located on the right-hand side of the
control are in the correct position (the blue switch must be up). Press the protective
motor switch FB1 once for a short time.
*The control is situated in a separate box in case of drive type S.
The main power switch is situated in the door of this box.
