Foreword
Dear reader,
these Operating Instructions provide all information necessary to
safely operate the Cassette Lifts K70, K90 and K90 ACTIVE.
The Cassette Lifts are designed and constructed in accordance with
state-of-the-art technology and recognised safety standards. Per-
sons and material assets can however still be at risk, 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 Cassette 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 entire lifetime of the Cas-
sette Lift. Chapter 11 of these Operating Instructions contains an In-
spection Log that is required by the technical expert for his / her an-
nual inspection of the Cassette Lift.
If you sell the Cassette Lift, hand these Operating Instructions over to
the new owner.
All details, figures and dimensions given in these Operating Instruc-
tions are non-binding. They cannot be used as the basis for any
claims whatsoever.
This document must not be reproduced or duplicated, in full or in part,
without the prior, written permission of the manufacturer.
The cassette lift must never be converted or modified in any way,
without seeking the prior, written permission of the manufacturer. The
manufacturer will accept no liability whatsoever if conversions or
modifications are carried out without authorisation.
Use only original spare parts or spare parts which have been ap-
proved 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 Cassette Lift. Using non-original or
unauthorised spare parts will render the guarantee null and void.
Contact our customer services department to order spare parts or
accessories (see Chapter 14, page 90).

terial damage being caused.
Therefore:
y Only use the Cassette Lift for the purpose for which it was in-
tended.
y Always adhere to information given in these Operating Instructions.
y Do not use the Cassette Lift for any other purposes, particularly
those given in Section 1.2. These are deemed to be improper use.
1.2 Improper Use
Any use other than that described in Section 1.1 is deemed to be im-
proper use.
These include in particular:
y Using to lift and lower goods.
y Using to lift and lower persons who are not seated in a wheelchair,

1.4 Product Monitoring
Please contact AMF-Bruns GmbH & Co. KG immediately if faults or
problems are encountered when operating your Cassette Lift or if ac-
cidents or "near-misses" occur.
AMF-Bruns will effect a solution to the problem with your help and the
knowledge gained will flow into future projects.
NOTE
Guarantee work on the cassette lift must only be carried out with the
prior agreement of AMF-Bruns GmbH & Co. KG.
The costs of such work will not be accepted by AMF-Bruns without
prior agreement.
1.5 Danger Zone
The danger zone is any area on, below or within the range of move-
ment of the platform, as well as around the drive and carrier system,
in which persons are exposed to the risk of injury or damage to health.
CAUTION!
Risk of injury through movements of the Cassette Lift.
There are a number of risks of personal injury if standing within the
danger zone.
Therefore:
y Only operate the Cassette Lift if there are no persons standing
within the danger zone.
y Keep the danger zone under observation and stop the Cassette
Lift if any persons enter the danger zone.
1.6 Safety Devices
1.6.1 Roll-off guard
As soon as the platform is raised from the ground, the roll-off guard
rises. This prevents the passenger in their wheelchair from rolling
backwards off the platform.
1.6.2 Signalling systems
The Cassette Lift gives a warning sound when the platform extends
from the cassette. Blinkers are fitted to both sides of the platform.
These signalling systems prevent hazards that are caused by the plat-
form being overlooked.

Safety
Page 12 of 92 Cassette Lift K70 / K90 / K90 ACTIVE
1.6.3 Door contact switch
A door contact switch is fitted to the vehicle door, above the Cassette
Lift. It disables all functions of the Cassette Lift when the door is
closed. This prevents the Cassette Lift from being operated inadvert-
ently or by unauthorised persons.
1.7 Safety and Accident Prevention
Regulations
Adhere to the following notes in order to prevent personal injuries and
material damage.
y The Cassette Lift must only be operated if all safety and protective
devices are correctly fitted (see Section 1.6). Such devices must
only be removed to enable maintenance and repair work to be
carried out. All safety and protective devices must be replaced im-
mediately after such work has been completed. If they are not re-
placed correctly, there is a risk of injury.
y The Cassette Lift must only be used for the purpose for which it is
intended, otherwise dangerous situations, with resultant injuries,
may occur (Proper use: see Section 1.1, page 9).
y The owner is responsible for ensuring that proper use is adhered
to, in particular that the Cassette Lift is only operated by authorised
persons.
y It is forbidden for persons to ride on the platform if they are not in
a wheelchair.
y Proper use of the Cassette Lift also includes adherence to the
specified maintenance and repair work, in particular the strict ad-
herence to the maintenance intervals (see Chapter 5.5, page 40).
If such work is not carried out, trouble-free operation cannot be
guaranteed. There is a risk of personal injury and material damage
being caused. We recommend that maintenance records are kept.
y The Cassette Lift must be inspected by a technical expert after it
has been installed. During the inspection, faults affecting the safety
should be systematically identified and remedial action taken (see
"Inspection Log", page 68).
This inspection must be repeated at intervals of not more than one
year if the Cassette Lift is used commercially or communally.
We recommend that this annual inspection is also carried out if the
Cassette Lift is used privately.
y An inspection must also be carried out by a technical expert before
the Cassette Lift is put back into service if modifications are made
to the construction or major repairs are carried out on load-bearing
parts of the Cassette Lift.

Safet
y
Cassette Lift K70 / K90 / K90 ACTIVE Page 13 of 92
y The Cassette Lift must not be operated in a faulty condition, as
severe injuries may be caused by this. If faults occur, do not use
the Cassette Lift until repairs have been effected.
y Do not deposit any items on the Cassette Lift. Persons can suffer
injuries if such items fall off the platform.
y Switch the Cassette Lift OFF before carrying out maintenance or
repair work, this includes cleaning work. Make certain that no other
person can switch the Cassette Lift ON (e.g. by disconnecting the
starter battery). If this is not done, there is a risk of injury.
y Use only original spare parts and accessories that have been ap-
proved of by the manufacturer. If other parts are used, the manu-
facturer will not accept liability for the consequences.

2 Description
Persons who are wheelchair-bound can be embarked into or disem-
barked from a vehicle using the Cassette Lift.
The main components of the Cassette Lift are:
y the platform,
y mechanics and hydraulics with carrier arms,
y the cassette and
y the operating controls.
The aim of this chapter is to illustrate the construction and function of
the Cassette Lift. To this end, the individual assemblies and compo-
nents are described in the following sections.

2.1.1 Platform
The platforms on the Cassette Lifts K70, K90 and K90 ACTIVE are of
differing design:
With the K70 and K90, the wheelchair is pushed onto the platform in
the direction of the door of the vehicle, below which the Cassette Lift
is installed (see Figure 3).

With the K90 ACTIVE, the wheelchair is pushed onto the platform par-
allel to the vehicle, in the direction of the rear of the vehicle (see Figure
4).
Figure 4 : Cassette Lift K90 ACTIVE, Platform Access
All platforms are provided with a roll-off guard that automatically rises
when the platform is raised off the ground. This prevents the wheel-
chair from rolling backwards off the platform.
The side nearest the vehicle is provided with a transfer plate. During
the raising and lowering procedure, this transfer plate forms a guard
that prevents the passenger’s feet from being caught between the
platform and the underside of the vehicle (see Figure 3 and Figure 4,
page 16). When the platform reaches the same level as the floor inside
the vehicle, the transfer plate folds down onto the floor. The passen-
ger then uses the transfer plate as a bridge to cross from the platform
into the vehicle (see Figure 5 and Figure 6, page 17).

Figure 6 : Cassette Lift K90 ACTIVE, Interior Floor Level
Guards are provided on all other sides of the platform to prevent the
wheelchair from rolling off the platform (see Figure 5, page 16, and
Figure 6).
On the K70 and K90, one of the platform’s two side guards is option-
ally shortened to extend roughly half way along that side. This pro-
vides side access to the platform, making it easier for the passenger
to roll on and off the platform when there is limited space available
outside the vehicle (see Figure 7).
Figure 7 : Cassette Lifts K70 and K90 with Side Access
When the platform on the K70 or K90 is retracted into the cassette,
the raised roll-off guard acts as a cover for the cassette (see Figure
8, page 18). With the K90 ACTIVE, the platform side guard acts as a
cover for the cassette (see Figure 9, page 18). In each case this pre-
vents dirt from entering the mechanics of the Cassette Lift.

2.1.2 Mechanics and hydraulics with carrier
arms
The hydraulically-powered carrier arms of the lift raise and lower the
platform and keep it horizontal. In order to do this, the carrier arms
are designed as parallelograms.
When the carrier arms have lowered the platform to the height of the
cassette, the platform can be retracted into the cassette. In this po-
sition, the carrier arms are in the horizontal and parallel to the plat-
form. The transfer plate automatically folds down when the platform
is retracted.
On the K70 and K90 there are two carrier arms on both the left- and
right-hand sides of the platform (see Figure 10).

On the K90 ACTIVE there are two carrier arms between the platform
and the cassette (see Figure 11).
Figure 11 : Cassette Lift K90 ACTIVE, Retract Position
The platform is extended and retracted electrically.
K70:
The cassette is driven by an electric motor in the internal carriage
which is connected via a pinion to a rack the centre of the cassette.
K90 / K90 Active:
An electric motor in the internal carriage powers the drive shaft which
has a pinion on each end. These pinions mesh with the racks in the
left- and right-hand sides of the cassette.
The hydraulic aggregate with electrically powered hydraulic pump and
hydraulic fluid reservoir are contained in their own housing.
The Cassette Lift is optionally equipped with a manually-operated
pump. This allows the platform to be raised / lowered when the hy-
draulic pump fails.
2.1.3 Cassette
The cassette encloses the platform and all mechanical components
when the vehicle is being driven and thus protects them from dirt (see
Figure 12, page 20, and Figure 13, page 20). The cassette also con-
tains the carrier frame to which the internal carriage and carrier arms
are attached.
