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 authorized 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 (e.g.: the safety gear is completely locked).

DO NOT USE THE LIFT WITHOUT PROTECTION DEVICES OR WITH THE PROTECTION DEVICES INHIBITED.
FAILURE TO COMPLY WITH THESE REGULATIONS CAN CAUSE SERIOUS INJURY TO PERSONS, AND IRREPARABLE DAMAGE TO THE LIFT AND THE VEHICLE BEING LIFTED.

Picture 6

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 danger areas when 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 is no person on the platforms during up and down movements and during standing.

Picture 7

GENERAL RISKS FOR LIFTING OR DESCENT:
The following safety equipments are 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 valve. When the oil pipe is burst in the circuit of hydraulic pressure, the relevant

Picture 8 (overflow valve)

antiknock and overflow 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)

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 (Picture 11)
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.

RISK OF FALLING OFF (PERSONNEL)
During up and down operations, personnel are prohibited from entering the platforms and the vehicle to avoid falling off.

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.
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 SLIPPING (Picture 12)
The floor caused by lubricant contamination of around the lift. The area beneath and immediately surrounding the lift and also the platforms must be kept clean. Remove any oil spills immediately.

RISK OF ELECTRIC SHOCK
Risk of electric shock of the areas of insulated in electric equipment’s were shattered.
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 INAPPROPRIATE 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.
