Foreword
Dear Reader,
these Operating Instructions serve to provide all infor-
mation required for the safe use of the Linear Lift.
The Linear Lift is designed and constructed in accordance
with state of the art technology and recognised safety
standards. Persons and materials can however be endan-
gered, as not all danger areas can be eliminated if the
functional capability is to be maintained. Accidents caused
by these dangers can however be prevented by strictly
observing these Operating Instructions. Over and above
this, the operational efficiency of your Linear Lift can be
used to the full and unnecessary faults can be prevented.
After reading these Operating Instructions for the first time,
keep them in a safe place for future reference over the en-
tire lifetime of the Linear Lift. Chapter 11 of these Operating
Instructions contains an Inspection Log that is required by
the technical expert for his / her annual inspection of the
Linear Lift.
If you sell the Linear Lift, hand these Operating Instructions
over to the new owner.
All details, figures and dimensions contained in these Op-
erating Instructions are non-binding. No claims in any form
can be derived from these.
This document must not be reproduced or duplicated, in
full or in part, without the prior, written permission of the
manufacturer.
The Linear Lift must never be converted or modified in any
way, without seeking the prior, written permission of the
manufacturer. The manufacturer will not be held responsi-
ble in any way whatsoever if conversions or modifications
are carried out without authorisation.
Use only original spare parts or spare parts which have
been approved of by the manufacturer. If spare parts other
than these are used, this can have a negative effect on the
specified characteristics, the functionality and safety of the
Linear Lift. Using non-original or unauthorised spare parts
will render the guarantee null and void.

1.6 Safety Devices
1.6.1 Guardrails
The guardrails fold down to the horizontal position, togeth-
er with the platform, when the Linear Lift’s platform is low-
ered from the stowed position to the deployed position.
They provide support for the passenger and increase the
sense of security when the platform is being raised or low-
ered.
1.6.2 Roll-off guard
A roll-off guard is fitted to the side of the platform furthest
from the vehicle. When the platform is raised, the roll-off
guard rises automatically and latches in position. This pre-
vents the passenger in their wheelchair from rolling off the
platform.
1.7 Safety and Accident Prevention
Regulations
Adhere to the following notes in order to prevent personal
injuries and material damage. Also adhere also to the rele-
vant safety and accident prevention regulations laid down
by the trade associations.
 The Linear Lift must only be operated if all safety and
protective devices are correctly fitted (see Section 1.6,
page 10). Such devices must only be removed in order
to enable maintenance and repair work to be carried
out. All safety and protective devices must be replaced
immediately after such work has been completed. If
they are not replaced correctly, there is a high risk of in-
jury.
 The Linear Lift must only be used for the purpose for
which it is intended, otherwise dangerous situations,
with resultant injuries, may occur (Proper use: see Sec-
tion 1.1, page 7).
 The owner is responsible for ensuring that proper use is
adhered to, in particular that the Linear Lift is only oper-
ated by authorised persons.

Safety
Linear Lift AL1 Page 11 of 76
 If the Linear Lift is used commercially or as a public utili-
ty, the owner must ensure that operating personnel are
familiar with the operation of the Linear Lift under all op-
erating conditions by giving training and familiarisation
courses.
 In order to be able to transport wheelchair-bound per-
sons, the vehicle must be fitted with the necessary spe-
cial equipment in accordance with DIN EN 75078. To
prevent dangers in road traffic, the Linear Lift must be
equipped with warning lights or warning markings.
 A number of dangers may arise during operation due to
adverse lighting conditions. The owner is obliges to
equip the vehicle or the Linear Lift with the correspond-
ing lighting fixtures.
 It is forbidden for persons to ride on the platform id they
are not in a wheelchair.
 Proper use of the Linear Lift also includes adherence to
the specified maintenance and repair work, in particular
strict adherence to the maintenance intervals. If such
work is not carried out, trouble-free operation can not
be guaranteed. Risks of personal injury and material
damage can occur. We recommend that maintenance
records be kept.
 If the Linear Lift is used commercially or as a public utili-
ty, it must be inspected by a technical expert at intervals
of not more than 1 year after commissioning. During in-
spection, faults affecting the safety should be systemat-
ically identified and remedial action taken (see "Inspec-
tion Log", page 60).
 Do not deposit any items on the Linear Lift. Persons can
suffer injuries if such items fall off the platform.
 The Linear Lift must not be operated in a faulty condi-
tion, as serious injuries may be caused by this. If faults
occur, do not use the Linear Lift until repairs have been
effected.

Safety
Page 12 of 76 Linear Lift AL1
 Switch the Linear Lift OFF before carrying out mainte-
nance or repair work, this includes cleaning work. Make
certain that no other person can switch the Linear Lift
ON (e.g. by disconnecting the starter battery). If this is
not done, there is a risk of injury.
 Use only original spare parts or spare parts which have
been approved of by the manufacturer. If non-original or
unauthorised replacement parts are used, this will ren-
der the guarantee null and void.
1.8 Disposal
When the Linear Lift's useful life has expired, it must only
be disposed of by qualified specialists. The manufacturer
will accept no liability for damage caused by incorrect dis-
posal.

2 Description
Persons who are wheelchair-bound can be embarked into
or disembarked from a vehicle using the Linear Lift.
The main components of the Linear Lift are:
 the platform,
 the lifting unit with carrier arms, guardrails and floor an-
chorages,
 the hydraulic system and
 the operating controls.
The aim of this chapter is to illustrate the construction and
function of the Linear Lift. To this end, the individual as-
semblies and components are described in the following
sections.

2.1.1 Platform
The platform has an anti-slip grating surface and is
equipped with side roll-off guards. These prevent the pas-
senger’s wheelchair from rolling off the side of the plat-
form.
A roll-off guard is fitted to the side of the platform furthest
from the vehicle (see Figure 1, page 13). When the platform
is lowered fully to the ground, the roll-off guard folds down.
This provides the passenger in the wheelchair with easy
access the platform. As soon as the platform is raised
from the ground, the roll-off guard rises and latches in po-
sition. This prevents the passenger’s wheelchair from roll-
ing backwards off the platform.
Figure 2: Linear Lift AL1 Solid, Embarkation and Disembarkation Level
The Linear Lift AL1 Solid has a one-piece platform. The
platform of the Linear Lift AL1 Panorama is made up of two
sections such that it is shortened when folded up to the
stowed position.

This enables a Linear Lift with a long platform to be in-
stalled in vehicles with restricted interior height. In addition
to this, the driver has a clear view through the rear window
when driving. Over and above this, the fact that a Linear
Lift is installed in the vehicle can not be seen from the out-
side (see Figure 3 and Figure 4).

Description
Page 16 of 76 Linear Lift AL1
The platform of the Linear Lift AL1 Split is split lengthwise.
When it is stowed in the driving position, the two halves of
the platform separate (see Figure 5). Because of this, it is
possible to enter and leave the vehicle by way of the door
in which the Linear Lift is installed, even though the Linear
Lift is in the vertical, stowed position.
Figure 5: Linear Lift AL1 Split, Stowed Position
2.1.2 Transfer plate
A transfer plate is fitted to the Linear Lift. When the plat-
form reaches the same level as the vehicle’s floor when
being raised (embark / disembark level), the transfer plate
closes the gap between platform and vehicle. This ensures
convenient, safe embarkation / disembarkation (see
Figure 1, page 13 and Figure 2, page 14).
Platform

Description
Linear Lift AL1 Page 17 of 76
2.1.3 Lifting unit
The lifting unit represents the connection between platform
and vehicle. The lifting and lowering movements are car-
ried out by four carrier arms that are powered by hydraulic
cylinders (see Figure 1, page 13). The carrier arms act on
carrier struts, to which the platform and guardrails are at-
tached. The platform and guardrails automatically fold
down on elbow joints actuated by the carrier arms when
the Linear Lift is lowered from its vertical position.
When the Linear Lift is raised to a level above the floor of
the vehicle, to the stowed position, the guardrails and plat-
form are folded up to the vertical, stowed position. Be-
cause of this, the Linear Lift takes up a minimum of space
in the vehicle (see Figure 5, page 16).
The carrier arms are connected to the vehicle by the floor
anchorages (see Figure 2, page 14).
2.1.4 Hydraulic system
The hydraulic system’s motor, pump and oil reservoir are
located in the switch box on the side of the Linear Lift (see
Figure 1, page 13). The operating voltage for the motor is
supplied by the starter battery. The hydraulic cylinders that
are powered by the pump are located between the carrier
arms.
The hydraulic system can be manually operated in an
emergency.
