Chapter 3.SAFETY
Read this chapter carefully and completely since important information for the safety
of the operator or others in case of improper use of the lift is included.
In the following text there are clear explanations regarding certain situations of risk or
danger that may arise during the operation or maintenance of the lift, the safety
device installed and the correct use of such systems, residual risks and operative
procedures to use ( general specific precautions to eliminate potential hazards).
Lifts are designed and built to lift vehicles and hold them in the elevated position in
an enclosed workshop. All other uses of the lifts are unauthorized. In particular, the
lifts are not suitable for:
-washing spray work;
-creating raised platforms for personnel or lifting personnel;
-use as a press for crushing purposes;
-use as elevator;
-use as a lift jack for lifting vehicle bodies or changing wheels.
The manufacturer is not liable for any injury to persons or damage to vehicles and
other property caused by the incorrect and unauthorized use of the lifts.
During lifting and descent, the operator must remain in the control station as the
diagrams illustrated.
As the diagrams illustrated: The presence of persons inside the danger zone indicated
is strictly prohibited. During operations persons are admitted to the area beneath the
vehicle only when the vehicle is already in the elevated position, when the platforms
are stationary, and when the mechanical safety devices are firmly engaged (eg : the
safety gear is completely locked).
DO NOT USE THE LIFT WITHOUT PROTECION DEVICES OR WITH THE
PROTECTION DEVICES INHIBITED.
FAILURE TO COMPLY WITH THESE REGULATION CAN CAUSE SERIOUS INJURY TO
PERSONS, AND IRREPEARABLE DAMAGE TO THE LIFT AND THE VEHICLE BEIN
LIFED.

Chapter 3.SAFETY
GENERAL PRECAUTIONS
The operator and the maintenance fitter are required to observe the prescriptions of
safety regulation in force in the country of installation of the lift.
Furthermore, the operator and maintenance fitter must:
-always work in the stations specified and illustrated in this manual;
-never remove or deactivate the guards and mechanical, electrical, or other types of
safety devices;
-read the safety notices placed on the machine and the safety information in this
manual.
In the manual all safety notices are shown as follows:
WARNING: indicates following operations that are unsafe and can cause minor
injury to persons and damage the lift, the vehicle or other property.
CAUTION: indicates possible danger that can result in serious injury to people and
damage property.
RISK OF ELECTRIC SHOCK: a specific safety notice placed on the lift in areas
where the risk of electric shock is particularly high.
RISK AND PROTECTION DEVICES
We shall now examine the risks that operators or maintenance fitters may be exposed
to when the vehicle is standing on the platforms in the raised position, together with
the various safety and protection devices adopted by the manufacturer to reduce all
such hazards to the minimum:
For optimal personal safety and safety of vehicles, observe the following regulations:
-do not enter the safety and safety of vehicles are being lifted. (Picture 6)
-make sure the vehicle is positioned correctly. (Picture 7)
-be sure to lift only approved vehicles, never exceed the specified carrying capacity,
maximum height, and projection (vehicle length and width);
-make sure that there are no person on the platforms during up and down movements
and during standing.

Chapter 3.SAFETY
GENERAL RISKS FOR LIFTING OR DESCENT :
The following safety equipments is used to protect over loading or the possibility of
engine failure.
In the condition of over loading, the overflow valve will open and directly return oil
to the oil tank. (see Picture 8)
Each bottom of oil cylinder is equipped with antiknock and locked valve. When the
oil pipe is burst in the circuit of hydraulic pressure, the relevant antiknock and locked
valve will work and limit the speediness of platform. (see Picture 9)
Safety tooth and gear module are parts which guarantee the safety of personnel
beneath the machine in failure condition of other protections. So make sure the
integrity of gear module and that the safety tooth has occluded completely. (Picture
10)
Picture 10 Safety tooth and gear module
There is nothing abnormal should be left on the safety modules to prevent safety
gear from occlude normally.
RISKS FOR PERSONNEL
This heading illustrates potential risks for the operator, maintenance fitter, or any
other person present in the area around the lift, result from incorrect use of the lift.
RISKS FOR EXTRUSION
During up and down operations, personnel leave the said area without following the
rule and instruction.
During up and down operations, no person is admitted to work beneath the movable
parts of the lift, should work in the safe zone. (Picture 6)
RISK OF IMPACT
Before the operator begins up and down movements, make sure that there are no
personnel inside the danger zone. When, due to operational reasons, the lift is stopped
at relatively low elevations (lower than 1.75m above the ground) personnel must be
careful to avoid impact with parts of the machine not marked with special colors.
Picture 11
RISK OF FALLING OFF (PERSONNEL)
During up and down operations, personnel are prohibited from entering the platforms
and the vehicle to avoid falling off.

USER
USER’ ’S SMANUAL MANUAL
13
Chapter 3.SAFETY
RISK OF FALLING (VEHICLE)
This hazard may arise in the case of incorrect positioning of the vehicle on the
platforms, overweight of the vehicle, or in the case of vehicles of dimensions that are
not compatible with the capacity of the lift.
The photocell does not work well to let the lift platforms do not in the same level.
When the platform is being tested, the vehicle engine can not be turned on.
There is nothing should be placed on the lift-lowering area and the movable parts of
the lift.
RISK OF SLIPPINE
Caused by lubricant contamination of the floor around the lift. The area beneath and
immediately surrounding the lift and also the platforms must be kept clean. Remove
any oil spills immediately.
Picture 12
RISK OF ELECTRIC SHOCK
Risk of electric shock in areas of insulated and shattered electric equipments.
Do not use jets of water, steam solvents or paint next to the lift, and take special care
to keep such substances clear of the electrical control panel.
RISKS RELATED TO IMAPPROPRIATE LIGHTING
The operator and the maintenance fitter must be able to assure that all the areas of the lift are
properly and uniformly illuminate compliance with the laws in force in the place of installation.
During up and down operations, the operator should continually observe the lift and
can operate it only in the position of operator. When lifting and lowering the
vehicle, the cushion needs being put in the bottom of chassis.
The handling of safety devices is strictly forbidden. Never exceed the maximum
carrying capacity of the lift, make sure the vehicles to be lifted have no load.
It is therefore essential to adhere scrupulously to all regulations regarding use,
maintenance and safety contained in this manual.

Oil make-up “adjust” operation ( normal service period):
after completion of machine installation and adjustment in the application process, the
right platform is lower than the left one because of air in the oil cylinder not being
excluded completely normal looses or leakage of the hydraulic oil.
When conducting oil make-up operation, the platforms must not be load.
Adjustment process:
-switch off “the work stop valve G” (dextrorotary)
-If the left platform is little lower (P1), turn on “ the oil make-up valve H” (clockwise
rotation 90º)
-If the right platform is little lower (P2), turn on “ the oil make-up valve I” (clockwise
rotation 90º)
-Click the “lift” button SB1, and then the single side of platform is lifted alone.
-after the two platforms both have the same height, close the oil make-up stop valve “H”
or “I”, turn on “the work stop valve”, the oil adjustment process comes to the end.
EMERGENCY MANUAL OPERATION FOR LOWERING (POWER
