INSTALLATION SCHEME FOR SCISSOR LIFT

PE 6001T DOUBLE SCISSOR LIFT 3T
Read carefully and completely this chapter since important information is included about
the operator safety in the case of improper use of the lift.
In the following text there are some clear explanations regarding certain situations of risk
or danger that may arise during the operation or maintenance on the lift, the safety devices
installed and the correct use of such systems, residual risks and operative procedures to use
(general precautions used 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 elevator for single parts of vehicles.
The manufacturer is not liable for any injury to persons or damages to vehicles and to other
property caused by the incorrect and unauthorized use of the lifts.
During lifting and descendant phases, the operator must remain in the control station, like the
diagrams illustrates.
As the diagrams illustrate, the presence of persons inside the indicated danger zone is strictly
prohibited. 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.
DO NOT USE THE LIFT WITHOUT THE PROTECTION DEVICES OR WITH THE PROTECTION DEVICES
INHIBITED. FAILURE IN FOLLOWING THESE RULES CAN CAUSE SERIOUS INJURY TO PERSONS,
AND IRREPARABLE
DAMAGE TO THE LIFT AND/OR TO THE VEHICLE BEING LIFTE

PE 6001T DOUBLE SCISSOR LIFT 3T
GENERAL PRECAUTIONS
The operator, the installer and the maintenance fitter are required to observe the prescriptions
of the 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 the mechanical, electrical or other types of
safety devices;
- Read the safety notices placed on the lift and the safety information in this manual.
In the manual all safety notices are shown as follows:
WARNING : indicates operations that are unsafe and can cause minor injury to persons and/or
damage to the lift, the vehicle or other property.
CAUTION: indicates possible danger that can result in serious injury to people and/or damage to
properties.
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 its raised position, together with the various safety and
protection devices adopted by the manufacturer to reduce all such hazards to the minimum:
For an optimal personal and vehicles safety, observe the following regulations:
- Do not enter the danger areas when vehicles are being lifted. (Picture 5)
- Make sure the vehicle is positioned correctly. (Picture 6)
- Be sure to lift only approved vehicles, never exceeding 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 the standing position.
GENERAL RISKS FOR LIFTING OR DESCENDANT PHASES:
The following safety equipment is used to protect from over loading or from the possibility
of engine failure. In the condition of over loading, the overflow valve will open and it will
directly return the oil to its tank. (Picture 7)Each bottom of the oil cylinders are equipped
with antiknock valve. If the oil pipe bursts, the specific valve will be activated and it will
limit the lowering speed of the platforms.(Picture 8)

SAFETY

PE 6001T DOUBLE SCISSOR LIFT 3T
RISKS FOR PERSONNEL
This manual illustrates potential risks for operators, maintenance fitters or any other person standing in
the area around the lift when an incorrect use of it is carried out.
RISKS IN USING THE LIFT
During the up and down operations the personnel must stand within the safety area, following the rules
and the instruction given by the manufacturer.
During the up and down operations no one is allowed to work beneath the movable parts of the lift, but
he has stand in the safety zone.
RISK OF IMPACT (Picture 9)
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 that are 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
lifted to avoid falling o.
RISK OF FALLING (VEHICLE) (Picture 10)
This hazard may arise in the case of incorrect positioning of the vehicle on the platforms, overweight of
the lifted vehicle, or in the case the vehicle dimensions are not compatible with the capacity of the lift.
When the platform is being tested, the vehicle engine cannot be turned on.
There is nothing that should be placed on the lift-lowering area and the movable parts of the lift.
RISK OF SLIPPING (Picture 10)
The area beneath and immediately surrounding the lift, or its platforms, must be kept clean. Remove any
oil spills immediately. Keep Clean the working area.
RISK OF ELECTRIC SHOCK
The risk of electric shock in the insulated areas is shattered.
Do not use jets of water, steam solvents or paint next to the lift and take special care to keep such
substances away from the electrical control panel.
RISKS RELATED TO INAPPROPRIATE LIGHTING
The operator and the maintenance fitter must be able to assure that all of the lift areas are properly and
uniformly illuminated, in the respect of the laws in force in the place of installation.
During up and down operations the operator should constantly observe the lift movements and he can only
operate it through the operator safety zone. The handling of safety devices is strictly forbidden.
Never exceed the maximum carrying capacity and make sure that the lifted vehicle has no loads on board.
It is also essential to adhere scrupulously to all of the regulations, maintenance and safety contained in this
manual.
