CHAPTER 4 : SAFETY
It is vital to read this chapter of the manual carefully and from beginning to end as it contains
important information regarding the risks that the operator and the maintenance  tter may be
exposed to in the eventuality that the lift is used incorrectly.
The following text contains clear explanations regarding certain situations of risk or danger that may
arise during the operation or maintenance of the lift, the safety devices installed and the correct use
of such systems, residual risks and operative procedures to use (general and speci c precautions to
eliminate potential hazards).
In particular, the lift is not suitable for:
• Washing and respire work;
• Creating raised platforms or lifting personnel;
• Use as a makeshift press for crushing purpose;
• Use as goods lift
THE MANUFACTURE DISCLAIMS ALL LIABILITY FOR INJURY TO PERSONS OR DAMAGE TO
VEHICLES AND OTHER PCABLERTY CAUSED BY THE INCORRECT AND UNAUTHORISED USE
OF THE LIFT.
During lift and descent movements, the operator must remain at the front of the vehicle. The
presence of persons inside the danger zone indicated in the same  gure is strictly prohibited. The
presence of persons beneath the vehicle during operations is permitted only when the vehicle is
parked in the elevated position.
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 IRREPERABLE
DAMAGE TO THE LIFT AND
THE VEHICLE BEING LIFTED.
WARNING
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;

GENERAL PRECAUTIONS
RISKS OF ELECTRIC SHOCK
RISKS AND PROTECTION DEVICES
LONGITUDINAL AND LATERAL MOVEMENT
The operator and the maintenance tter are required to observe the prescriptions of accident
prevention legislation in force in the country of installation of the lift.
Furthermore, the operator and the maintenance tter must:
Always work in the scheduled working area as shown in the manual
Never remove deactivate the guards and mechanical, electrical, or other types of safety devices.
Read the safety notices afxed to the machine and the safety information in this manual.
Specic safety notice afxed to the lift in areas where the risk of electric shock is particularly high.
We shall now examine the risks to which the operator and the maintenance tters may be exposed
when the vehicle is immobilized in the raised position, together with the protection devices and
adopted by the manufacture to reduce all such hazards to the minimum.
The equipment chosen must be suitable for safe lifting and moving, bearing in mind the dimensions
and weight. It is not allowed, when get to the height, to shift the load backward and forward or left
and right, which will cause the vehicle falls off and slant.
Risk of vehicle falling

LINCOS®AUTOMOTIVE TOOLS 14
PORTABLE FOUR ARMS SCISSOR LIFT STD-3128
WARNING
DO NOT ATTEMPT TO MOVE THE TOTARY TABLE AND THE VEHICLE
SUPPORT WHEN IT IS LIFTING.
It is important to position the vehicle on the lift so that the
weight is correctly distributed on the arms.
People rest inside the safety area while the vehicle raising
The engine is off, the lock engaged and it should be pulled to
activate the lock to work.
The vehicle is correctly positioned.
Only authorized vehicle are raised without exceeding the rate
capacity and overall dimensions.
The following safety devices have been installed to protect against overweight conditions and
equipment failure:
The thermal relay in the electric box will trip if the motor is overloaded.
The pressure-limit valve, located on the hydraulic oil power unit, will trip if the lift is overloaded.
In case of a sudden, great leakage in the hydraulic circuit (a broken pipe), the blocking valves, at the
bottom of each Cylinder, will trip.
This paragraph illustrates risks to which the operator, maintenance worker, or any person near the
operating area of the lift may be exposed in the case of impeccable use of equipment.
Correctly loaded vehicle
RISKS WHILE THE VEHICLE IS BEING RAISED
RISKS OF PERSONS

LINCOS®AUTOMOTIVE TOOLS 15
PORTABLE FOUR ARMS SCISSOR LIFT STD-3128
Possible if the operator controlling the lift is not in the specied
position at the command panel. When the platform and the vehicle
are descending, the operator must never be partly or completely
underneath the moving structure. During this phase the operator
must remain in the command zone.
This risk could be caused by the incorrect positioning on the arm disk support plates (g.14) or in
incorrect position of the arm disk support plates in relation to the lift. Ensure the center of gravity of
the vehicle, and then put four arms at the correct place to avoid such an occurrence.
NEVER BOARD THE VEHICLE AND/OR TURN THE ENGINE ON WHEN LIFT IS RAISED.
NEVER LEAN OBJECTS AGAINST THE POSTS OR LEAVE THEM IN THE AREA WHERE MOVING
PARTS ARE LOWERED
This could hamper lowering or cause the vehicle to fall from the rack.
Crushing risk Falling risk
RISK OF CRUSHING (OPEARATOR)
RISK OF VEHICLE FALLING FROM LIFT
Risk of electric shock in areas of the lift cable. Do not use jets of water, steam (high pressure wash
units). Or paint in the immediate vicinity of the lift, and take special care to keep such substances
clear off the electrical command panel.
The operator and the maintenance tter must be able to assure that all the areas of the lift are
properly and uniformly illuminated in compliance with optics principle and the laws in force in the
place of installation.
RISK OF ELECTRIC SHOCK
RISK RELATED TO INAPPROPRIATE LIGHTING

This risk may arise due to spillage of lubricants in the surrounding area.
ALWAYS KEEPS THE AREA SURROUNDING THE LIFT CLEAN BY REMOVING ALL OIL SPILLS.
To avoid the risk of slipping, make use of the recommended personal protection (anti-slip footwear).

The manufacturer has used appropriate materials and construction techniques in relation to the
specied use of the machine in order to manufacture a reliable and safe lift. Note however, that
the lift must be used in conformity with the manufacturers prescriptions and the frequency of
inspections and maintenance work recommended in chapter 7 “MAINTENANCE” must be observed.
RISK RELATED TO IMPROPER USE
Persons are not permitted to stand or sit on the platforms during the lift maneuver or when the
vehicle is already lifted
All uses of the lift other than the uses for which it was designed are liable to give rise to serious
accidents involving the persons working in the immediate vicinity of the unit. It is therefore essential
to adhere scrupulously to all regulations regarding use, maintenance and safety contained in this
manual.

CHAPTER 5 : INSTALLATION
THE FOLLOWING OPERATIONS MUST BE PERFORMED EXCLUSIVELY BY SPECIALISED
TECHNICAL STAFF WITH AUTHORISATION FROM THE MANUFACTURER OR LICENSED
DEALER. IF THESE OPREATIONS ARE PERFORMED BY OTHER PERSONS, SERIOUS
PERSONAL INJURY AND/OR IRREPERABL DAMAGE TO THE LIFT UNIT MAY RESULT.
INSTALLATION REQUISITE CHECKLIST
The STD-3128 can work inside only. It is also considered that the place of installation must be well
clear of areas destined to washing or painting, and away from solvent or paint storage areas or areas
where there is a risk of potentially explosive atmosphere.
STD-3128 lift is really simple. When transportation, just need to separate the frame, which include
arms, extendable arms, safety lock and so on, from the vehicle and pack them respective. Open the
packaging, check the components, and then install the lift INDOOR.
When the frame has been mounted, which include the extendable arm, safety lock, idler wheels and
so on, please check it, whether it loose or not. Mount the vehicle and the press connection plate, and
base board with 4-M8×25, at washer, elastic washer and nut.
After mounting, connect the hydraulic station and the oil pipe, and then switch on the power. But
at rst, check the voltage. If it isn’t the same as the requirement of the lift, replace the voltage. Then
nd a plug suitable for the lift.
Insert it according to the relative number. If the motor does work, it must be something wrong with
the hydraulic pump. Change another phase.
