CHAPTER 4 - PRODUCT DESCRIPTION
4.1 LIFT DESCRIPTION (Ref. Figure 1)
The flush mounted lift has been designed for the lifting of motor-vehicles for wheel alignment and
maintenance.
The maximum lifting weight is as specified on the serial plate.
All mechanical frames, such as platforms, extensions, base frames and arms have been built in steel
plate to make the frame stiff and strong while keeping a low weight
The electro hydraulic operation is described in detail in chapter 8.
This chapter describes the lift’s principal elements, allowing the user to be familiar with the machine.
As shown in figure 1, the lift is composed of two platforms (1) each equipped with a telescopic
extension (2), anchored to the ground by means of two base frames (3).
Platforms are linked to the base frame by means of a scissors lifting system.
The lifting system of each platform is composed of N.4 arms, two inferior (4) and two superior (5),
and a cylinder (6).
Lifting and lowering motion of the lift is controlled by the push buttons on the control panel (7) placed
next to the lift.
The mechanical safety operating by a pneumatic cylinder (8) is installed under each runway.
Two limit switches are installed in the power unit, one for the safety height and the other one for the
maximum lifting height.
Whenever the lift is to be lowered to the ground, the lift will stop at about 400 mm from the ground at
first, then press the final lowering button to lower the lift completely. A beep sound is heard during the
final travel.

CHAPTER 6 – SAFETY
Read this chapter carefully and completely because it contains important information for the safety
of the operator and the person in charge of maintenance.
The lift has been designed and built for lifting vehicles and making them stand
above level in a closed area. any other use is forbidden, including the following
operations:
The manufacturer is not liable for possible damages to people, vehicles or objects
resulting from an improper or unauthorized use of the lift.
For operator and people safety, a safety area at least 1m free away from the lift must be vacated
during lifting and lowering. The lift must be operated only from the operator’s control site in this
safety area.
Operator’s presence under the vehicle, during working, is only admitted when the vehicle is lifted
and platforms are not running.
Never use the lift when safety devices are off-line. People, the lift and the vehicles
lifted can be seriously damaged if these instructions are not followed.
6.1 GENERAL WARNINGS
The operator and the person in charge of maintenance must follow accident-prevention laws and
rules in force in the country where the lift is installed
They also must carry out the following:
•neither remove nor disconnect hydraulic, electric or other safety devices;
•carefully follow the safety indications applied on the machine and included in the manual;
•observe the safety area during lifting;
•be sure the motor of the vehicle is off, the gear engaged and the parking brake put on;
•be sure only authorized vehicles are lifted without exceeding the maximum lifting capacity;
•Verify that no one is on the platforms during lifting or standing.
6.2 RISKS DURING VEHICLE LIFTING
To avoid overloading and possible breaking, the following safety devices have been used:
•a maximum pressure valve placed inside the hydraulic unit to prevent excessive weight.
•a special design of the hydraulic system, in case of pipeline failure, to prevent sudden lift
lowering..
The maximum pressure valve has been preset by the manufacturer to a proper
pressure. DO NOT try to adjust it to overrun the rated lifting capacity.
6.3 RISKS FOR PEOPLE
All risks the personnel could run, due to an improper use of the lift, are described in this section.

REV. 02 17 / 30
6.4 PERSONNEL CRUSHING RISKS
During lowering of runways and vehicles, personnel must not be within the area covered by the
lowering trajectory. The operator must be sure no one is in danger before operating the lift.
Fig. 7a Fig. 7b Fig. 7c
6.5 BUMPING RISK
When the lift is stopped at relatively low height for
working, the risk of bumping against projecting parts
occurs.
Fig. 8
6.6 RISK OF THE VEHICLE FALLING FROM THE LIFT
Vehicle falling from the lift can be caused when the vehicle is improperly placed on platforms, and
when its dimensions are incompatible with the lift or by excessive movement of the vehicle.
In this case, keep immediately away from the working area.
Fig. 9a Fig. 9b Fig. 9c
6.7 SLIPPING RISKS
The risk of slipping can be caused by oil or dirt on the floor near
the lift.
Fig. 10
Keep the area under and around the lift clean. Remove all oil spills.
6.8 ELECTROCUTION RISKS
Avoid use of water, steam, and solvent, varnish jets in the lift area where electric cables are placed
and, in particular, next to the electric panel.

REV. 02 18 / 30
6.9 RISKS RESULTING FROM IMPROPER LIGHTING
Make sure all areas next to the lift are well and uniformly lit, according to local regulations.
6.10 RISKS OF BREAKING COMPONENT DURING OPERATION
Materials and procedures, suitable for the designed parameters of the
lift, have been used by the manufacturer to build a safe and reliable
product. Operate the lift only for the use it has been designed for and
follow the maintenance schedule shown in the chapter “Maintenance”. Fig. 11
6.11 RISKS FOR UNAUTHORIZED USES
The presence of unauthorized persons next to the lift and on the
platforms is strictly forbidden during lifting as well as when the vehicle
has been already lifted
Fig. 12
Any use of the lift other than that herein specified can cause serious accidents to
people in close proximity of the machine.

REV. 02 19 / 30
CHAPTER 7 – INSTALLATION
Only skilled technicians, appointed by the manufacturer, or by authorized
dealers, must be allowed to carry out installation. Serious damage to people and
to the lift can be caused if installations are made by unskilled personnel.
7.1 CHECKING FOR ROOM SUITABILITY
The lift has been designed to be used in covered and sheltered places free of overhead obstructions.
The place of installation must not be next to washing areas, painting workbenches, solvent or
varnish deposits. The installation near to rooms, where a dangerous situation of explosion can occur,
is strictly forbidden. The relevant standards of the local Health and Safety at Work regulations, for
instance, with respect to minimum distance to wall or other equipment, escapes and the like, must be
observed.
7.2 LIGHTING
Lighting must be carried out according to the effective regulations of the place of installation. All
areas next to the lift must be well and uniformly lit.
7.3 FOUNDATION
The lift must be placed sufficiently in the concrete pit prepared as shown in the figure 13. The floor
must be suitable for bearing maximum stress values, also in unfavorable working conditions. The
level difference between two pits MUST be less than 3mm, and the height difference within full
length of base frame MUST be less than 5mm. The new concrete must be adequately cured by at
least 20 days minimum.
A level foundation is suggested for proper installation. Small differences may
be compensated for by proper shimming. Any major slope change will affect
the level lifting performance. If the foundation is of questionable slope,
considering to pour the new one.
7.4 LIFT POSITIONING
Unauthorized persons are not allowed to enter during assembly.
•Locate the lift position in the pit according to the drive-on direction of the lift and referring to
the foundation layout (figure. 13). Be sure the side of each platform with the labels towar
d
outside.
•Transport each runway into the pit using hoisting means with load capacity of 500kg at least.
To prevent the platform from dropping during transport, it should be lifted according to its
centre of gravity.
•Place the control unit in the position provided for. The location of control unit can be
positioned in either left or right to meet the customer’s preference.
