INTENDED USE
This operator’s manual forms an integral part of the product: if the lift is sold on, all the
documentation must accompany it.
Read the warnings and instructions in this manual carefully; they supply important infor-
mation concerning SAFETY IN USE and MAINTENANCE.

U

Operator’s manual 61
KEEP THIS MANUAL IN A SAFE PLACE FOR FURTHER REFERENCE
This product has been designed to be used as a lifting device for cars and light transport
vehicles up to a maximum weight of 4300 Kg.
For rear wheel alignment, the lift is equipped with slip plates adjustable in three direc-
tions, transverse, longitudinal and diagonal, to allow all the movements necessary for
the adjustments.
The lift is effectively used also for maintenance and repairing operations and for the
vehicle testing lines by means of the play detector bench; the play detector bench is
hydraulically controlled by the same lift control unit.
The design specifications of this lift make it suitable for use indoors and outdoors shel-
tered under a roof.
The load must be distributed over the runways in accordance with the regulations in
force which, for lifts having maximum capacity in excess of 3000 kg, stipulate 1/3 at the
front and 2/3 at the rear or vice-versa, with the vehicle’s wheels placed at least 300 mm
from the end of the runway.
Therefore the maximum useful load fraction, 2866 kg per axle of the vehicle corresponding
to 2/3 of the maximum capacity, must absolutely never be exceeded, as this may impair
the stability and thus the intrinsic safety of the lifting device. For the same reason, load
differences between the two runways must not exceed 10%;
example: left hand runway 2,250 Kg, right hand runway 2,750 kg.
IMPORTANT: for correct, safe use of the equipment, users must ensure a lighting level
of at least 300 lux in the place of use.
WARNING
Never use the lift for washing cars.
WARNING
Use of the machine in potentially explosive atmospheres is forbidden.
WARNING
Never lift even very light loads on one runway only, as the lift might become danger-
ously unstable.
WARNING
The lift may not be used in any working condition not specifically envisaged in this
manual. In particular, lifting people is absolutely forbidden.
The manufacturer cannot be held responsible for any damage caused by improper,
incorrect or unreasonable uses.
WARNING
Never use the lift for lifting rail vehicles.

62 Operator’s manual
GENERAL SAFETY REGULATIONS
This equipment is for professional use only.
WARNING
Only one operator may work with the equipment at a time.
The lift must only be used by specifically trained, authorised staff.
Any tampering with or modification of the equipment not authorised in advance by the
manufacturer relieves the latter of responsibility for damage deriving from or due to
such procedures.
Removal of or tampering with the safety devices constitutes a violation of European
Regulations on safety. The manufacturer therefore declines all liability deriving from
tampering with these devices.
- The machine may only be used in places free from explosion or fire hazards.
- Original accessories must be used. Our machines are designed to take original acces-
sories.
- Installation must always be carried out by qualified staff in full accordance with the
instructions given below.
- Make sure there are no risky conditions while the equipment is being operated: in case
of malfunctioning, stop the machine at once and consult the technical support service
of the authorised dealer.
- Standing underneath the vehicle during raising and lowering is forbidden.
WARNING
Even minor work on the electrical system must be done by professionally qualified
staff (see specific legislation on this subject).
TRANSPORT
The machine, in its packaging, must be transported in accordance with the instructions
provided below:
- Protect the control unit from exposure to the weather and ensure that it is not subjected
to substantial variations in temperature. Since it is in its packaging, it must be handled
with a pallet truck or fork-lift truck, inserting the forks in the points shown in figure 3.
- As the lift structure is of considerable size, it is packaged with a wooden structure which
allows slinging with suitable slings. Never use steel ropes. The positions of the slings
and the hook are indicated in figure 4. For correct lifting, with the slings taut the hook
should be at least 2.5 m from the packaging.

UNPACKING
After removing the packaging make sure that the equipment’s various components are
undamaged, by checking that there are no visibly damaged parts (control unit, lift struc-
ture). In case of damage do not use the equipment (the lift) and contact professionally
qualified staff (your dealer).
The packaging materials (plastic bags, expanded polystyrene, nails, screws, pieces of
wood, etc....) must not be left within reach of children since they are potential sources
of danger.
Consign these materials to the specific collection centres if they are pollutant or not
biodegradable.
INSTALLATION AREA
The machine installation requires a usable space of min. 4,060 x 7,760 mm (fig.5).
From the control position the operator has a clear view of the entire lift and the surround-
ing area. The operator must not let any unauthorised person enter this area, and must
ensure that it is clear of potentially hazardous objects.
Do not install on loose or unstable surfaces.
The surface on which the lift is installed must withstand the loads transmitted during
operation.
This surface must have a capacity of at least 25 kg/cm2and a resistance class of
250R’bk.
The lift contact zones to the floor must be levelled.

Work environment conditions
- Relative humidity: from 30% to 95% without condensation.
- Temperature range: from 0°C to 40°C.
INSTALLATION
After unpacking, position the parts ready for assembly. During the handling phase, neces-
sary to find the right positioning of the lift on the ground, suitable slings or chains must
be used (fig. 6).
Once the exact position of the lift has been established place the control unit. The stand-
ard positioning is the one shown in figure 7, with the control unit on the left of the lift
and its control panel oriented on the other side of the lift. This will allow the operator a
good view of the whole working area.
The positioning distances are shown in figure 7, assuming as reference the front left
corner of the runway.

Procedure for fitting the dowels
The lift must be fixed to the floor; for this operation, the following devices are neces-
sary:
1. Hammer drill for drilling concrete, with 12 mm bit.
2. 16 FISCHER expansion plugs for heavy fixing duty, type FH II 12/50 H (or equivalent
model produced by other manufacturers).
3. Torque wrench with maximum setting at least 25 Nm.
Make sure that the concrete belongs to a Rbk resistance class greater than 250 kg/cm² to
a minimum depth of 140 mm.
Proceed as follows:
- Drill with bit Ø= 12 mm to a depth of 120 mm.
- Clean the hole.
- Tap the expansion plugs into the hole with a hammer.
- Tighten the bolts with a torque wrench, set at 25 Nm (if this value cannot be obtained,
the hole is too large or the concrete is not sufficiently solid).

SAFETY DEVICE
SPECIFICATIONS
The lift is provided with safety devices which grant the user the maximum security the
event of failure.
The safety devices are the following:
Mechanical device: this device is essentially composed of a claw and a rack (see fig. 11), and
immediately stops the sudden descent of the lift (within 100 mm height) in the event of
hydraulic line failure or a blow-out in the circuit. Therefore this very important device
must always be kept in perfect efficiency and any tampering or removal is forbidden. It
is pneumatically operated.
11
Hydraulic safety: this consists of a counterbalancing valve (see fig. 12) positioned on the
discharge of the lifting cylinder, which has the function of stopping the sudden descent
of the lift in the event of the hydraulic hoses breaking. The valve is calibrated so that the
lift’s descent speed will be lower than the value set by the regulations in force.
12

U
K
Operator’s manual 73
Electronic aligner (fig. 13): this device consists of 2 position transducers (potentiometers)
and the electronic control board.
The electronic control board reads the signals from the two position transducers to check
continuously whether the misalignment of the two runways has reached or exceeded 50
mm; if so, the circuit board cuts out the current function immediately, and switches the
lift to "alarm" status.
For further information on the behaviour of the lift in case of misalignment between the
runways, read the Chapter "Indicators and audible signals".
The device does not cover the runways of the built-in lift table.
Anti-crushing safety: the control board stops the descent when the runways reach a height
of approx. 780 mm from the ground and emits an intermittent sound:
To continue the descent, the pressed button must be released and then pressed again;
in this way, the runway descent will continue until the lift complete closure.
WARNING
No safety devices must ever be tampered with, disabled, moved or removed, as this
might put the operator at risk. The manufacturer declines all liability deriving from
failure to comply with the above rule.
