ATTENTION - SAFETY FIRST
Please pay careful attention to the next points/instructions!
Operator of the DELT
 stairlift
For every stairlift minimum one responsible person has to be appointed; during the
operation of the unit this person has to be easily reachable. The unit has to be
preserved failsafe. In case that the unit is acknowledged as not failsafe, it has to be
closed down immediately; Accidents have to be notified to the manufacturer
immediately.
The responsible person has to get sure once a week that no obviously dangerous
defects exist and that the within capture „CHARGES OF THE OPERATOR“
explained tasks are perceived.
User group:
Only specially instructed persons are to use the DELTA 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.
Duty cycle:
The DELT  stairlift was constructed for being 4 minutes in motion per 10 minutes.
In case that the stairlift is permanently in operation, the motor could get too warm
and becomes defective.
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
➔OMEGA stairlifts must only be used for the transport of persons in wheelchairs
or sitting on the fold down seat.
➔Never use the stairlift in the standing position.
➔OMEGA stairlifts must not be used for freight transportation.
➔Lock both the lift and the platform after use. Do not let children play on the lift.
➔Do not exceed the maximum platform load or maximum wheelchair size.
➔Pay attention to the instructions provided on the lift.
➔Pay attention to the following points for the correct use of the stairlift.

Load capacity:
The maximum load is indicated on the sideboard of the carriage.
Do not exceed this limit!
Attention:
The stairlift can only be used by one person at one time. It is not allowed to
transport an attendant person.
Keep hands and fingers away from the back of the carriage! Passengers must re
main 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.
Emergency call
In case that it is necessary for the individual user (for example: extrication stuff is
only reachable over the emergency call) or the authority enjoins it, the stairlift can be
executed with an emergency call button to summon for help. By pressing the
emergency button a loud emergency signal rings out.
Attention!
Do not use lift in the case of a fire. A power out can lead to dysfunction of the lift!
DELTA stairlifts are equipped with the following safety features:
-drive with self-locking gear and break
-overspeed governor
-side access ramps, locked
-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!
