SAFETY ARRANGEMENTS
These include :
Torsion beams which ensure
synchronisation and, if one of the
cylinders fails, the torsion bar
transfers the power to the cylinder
which is working properly.
Overpressure valves protect the
system against damage arising due
to excessively high oil pressure.
Fusible electrical cut-outs, and a
motor-protection switch
Mechanical gears to prevent the lift
from sinking back to its original
position in case of oil leakages.

5. SAFETY
It is important to read point number 5 of
this Manual properly since it contains
important information about the risks which
the operator of the lift will be exposed to if
the lift is not used properly. In what
follows, you will find information about how
to avoid dangerous situations.
WARNING.
The lift is designed and
constructed to lift vehicles and
to hold them in a certain position
in a covered working place. Any other form
of use is not permitted. In short, the lift is
not suitable for the following purposes :
Washing and spraying work.
To be used as a device for applying
force.
To be used as a goods lift.
To be used as a jack or for lifting
vehicles for changing wheels.
The manufacturer hereby refuses to
entertain any claims for damages arising in
connection with injury to persons or
damage to vehicle or other property
caused due to incorrect and/or
unauthorised use of the lift.
During lifting- and lowering movements,
the operator must be within the zone of
operation (1), as shown in Fig. 6. The
presence of any person in the safety zone
(2) is strictly forbidden. The presence of
persons under the vehicle is only permitted
if the vehicle is parked in the lifted position.
USE THE LIFT ONLY IF ALL THE SAFETY
ARRANGEMENTS ARE WORKING
PROPERLY. IF THESE RULES ARE NOT
FOLLOWED, SERIOUS INJURY COULD BE
CAUSED TO PERSONS AS WELL AS
IRREPARABLE DAMAGE TO THE LIFT AND
THE VEHICLE ON THE LIFT.

The following terms have been used in this
Manual to describe the various types of
risk :
DANGER : there is a direct possibility of
danger which could lead to serious injury
or death.
WARNING: this indicates situations and/or
actions which are unsafe and could lead to
injuries of various types except death.
CAUTION : this indicates situations and/or
actions, which are unsafe and could lead
to light injuries to persons and/or damage
to the lift, the vehicle or other properties.
RISK OF DAMAGE DUE TO
ELECTRICITY : Special safety
arrangements have been made on the lift
in places where the risks are very high.
RISKS AND PROTECTIVE MEDIA
The risks to which the operator is exposed
when the vehicle is in a raised position,
together with the protective media which
have been installed in order to limit the
possible dangers.
LONGITUDINAL AND LATERAL
MOVEMENTS OF THE VEHICLE.
Longitudinal and lateral movements
include the following : forward- and
backward movements of the load (the
vehicle). Lateral movements include
displacement of the vehicle to the left or
the right, particularly during the lifting
process. These movements can be
prevented by placing the vehicle securely
on the support arm rubbers (on the car-
jack support points).
WARNING
Do not move the vehicle when it
is on the platform. The platforms
and the rubber fittings should only be
removed at the lowest lifting position, and
when there is no load.

It is extremely important that the vehicle is
placed on the lift in such a manner that
there is an uniform distribution of weight
over the platforms (Fig. 7). Please note
that the motor side of the vehicle must
be placed on the side which cannot be
pushed out.
Fig. 7
To ensure the safety of persons and of
materials, you must see to it that :
The safety zone is kept under
observation during the lifting process.
The motor of the vehicle is switched
off, that it is in gear, and that the
handbrake is also fully applied.
The vehicle must be lifted on the car-
jack support points .
Due account has been taken of all the
dimensions and weights.
RISKS INVOLVED IN LIFTING A
VEHICLE
The following safety arrangements have
been installed in order to prevent
overloading and damage :
Limit switches, for limiting the
downward movement.
Overpressure valves offer protection
against damage due to excessive
lifting.
Thermal protection switches off the
power in the case of overloading.
RISKS TO PERSONS
This paragraph describes the risks to
which the operator or any other person
near the working area where the lift is in
operation, in case the lift is not used in the
appropriate manner.
RISKS INVOLVED IN MOVING A
VEHICLE
Movements may be caused during
activities which involve the application of
an adequate amount of force for moving
the vehicle (Fig. 8). In cases where the
vehicle being lifted is almost of the
maximum permissible weight or the
maximum permissible dimensions,
movements in the vehicle could lead to
overloading or unbalancing.
Fig. 8
RISKS INVOLVED IN POSITIONING A
VEHICLE
This type of risk may arise if the vehicle is
not properly placed on the rubber supports
(Fig. 9), or if the platforms are not properly
aligned with respect to the vehicle. One
can avoid this by always lifting the vehicle
using the car-jack support points , and to
place the vehicle as far as possible in the
centre of the platform.
Attention : while dismantling heavy parts
(for example the motor or shafts) please
note that the weight distribution ratios
change !
Fig. 9
Never rest any fittings or other objects
against the platform and never place such
objects under the platform when it has a
load mounted on it, since this can impede
the lowering operations and may cause
the vehicle to fall off the platform (Fig. 10).

6. CONTROLS AND OPERATION
(Fig. 14)Put the function button (10)in the lifting
position (1) until the desired height is
reached.
Fig. 11
The operating part of the electrical control
cabinet contains the following :
Parking
A COMBINED FUNCTION KEY Now press the button 7in order to activate
the mechanical lock.
with the following functions :
0 position : the electrical circuit of the lift
is not live. If necessary, a lock may be put
in place to prevent the misuse of the
platform.
Lowering
Turn the function button to the DOWN
position and hold the button in this
position. The lift will rise a few centimetres,
the mechanical lock will disengage and the
lift will fall back to the safety height. Press
the safety switch for the lowering operation
(7) for completing the last 400 mm of the
downward motion.
RISK OF ELECTROCUTION M position (1 and 2) : In these positions,
the electrical circuit is live, and the
protective arrangements can be operated.
Never spray water or steam or solvents or
paint in the area immediately surrounding
the platform and the control cabinet (Fig.
12). UP position : In this position, the lifting
valve and the motor are used, and the lift
can be raised.
Fig. 12
DOWN position : In this position, the
motor and the valve for the lowering
motion are used, and the lift can be
lowered to the safety height.
Lowering in case of emergencies (Fig.
15)
In case of a power failure, it is possible to
lower the platform in the following manner
:
Manually unlock the mechanical lock, and
turn the lowering motion valve (1) which is
located on the valve block, in the
anticlockwise direction, into the 'open'
position. Close the valve after the platform
has been lowered fully.
RISK OF SLIDING OUT
This risk can be overcome by avoiding the
spillage of oil or grease in the area
surrounding the lift (Fig. 13). Apart from
that, any oil spillage which may occur
should be thoroughly removed from the
spot. Fig. 14
