Chapter 3 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
fitter 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 specific
precautions to eliminate potential hazards).
WARNING
Lift is designed and built to lift vehicles and hold them in
the elevated position in a closed workshop. All other uses
are unauthorized; 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
◆Use as a jack for lifting vehicles or changing wheels.
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 in the command station as defined in figure 8. The
presence of persons inside the danger zone indicated in the
same figure 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.
-5-

USER’S MANUAL
Fig. 10 Working Area
3.1 GENERAL PRECAUTIONS
The operator and the maintenance fitter 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 fitter must:
◆Always work in the scheduled working area as shown
in the manual;
◆Never remove or deactivate the guards and
mechanical, electrical, or other types of safety devices;
◆Read the safety notices affixed to the machine and the
safety information in this manual.
In the manual all safety notices are shown as follows:
DANGER: indicates imminent danger that can result in
serious injury or death.
WARNING: indicates situations and/or types of maneuvers
that are unsafe and can cause injuries of various degrees or
death.
CAUTION: indicates situations and/or types of maneuvers
that are unsafe and can cause minor injury to persons and/
or damage the lift, the vehicle or other psaltery.
3.3 RISKS AND PROTECTION DEVICE
We shall now examine the risks to which the operator and
the maintenance fitters 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.
3.4 LONGITUDINAL AND LATERAL
MOVEMENT
Longitudinal movement is considered the backward and
forward shifting of the load.
Lateral movement implies the shifting to the left or right of
the vehicle, especially during the lifting phase on the rack.
These movements can be avoided by positioning the
vehicle correctly on the arm disk support plates, which
must be previously adjusted to the same height (by
loosening or tightening) as the vehicle.
Do not move the vehicle in relation to the arms or adjust
arms and disk support plates until the arms have been
totally lowered, i.e. the disk support plates must be free
from all contact with the vehicle.
3.2 RISKS OF ELECTRIC SHOCK
Specific safety notice affixed to the lift in areas where the
risk of electric shock is particularly high.
Fig. 11 Risk of Vehicle Fall
-6-

USER’S MANUAL
WARNING
DO NOT ATTEMPT TO MOVE THE VEHICLE WHEN
IT IS RESTING ON THE DISK SUPPORT PLATES.
It is important to position the vehicle on the lift so that the
weight is correctly distributed on the arms. (Fig. 12) For
person and equipment safety, it is important that:
◆People rest inside the safety area while the vehicle
raising. (Fig. 10)
◆The engine is off, the clutch engaged and the parking
brake pulled.
◆The vehicle is correctly positioned. (Fig. 12)
◆Only authorized vehicle (Fig. 8 & Fig. 9) are raised
without exceeding the rate capacity and overall
dimensions.
Fig. 12 Correctly Loaded Vehicle
3.5 RISKS WHILE THE VEHICLE IS BEING
RAISED
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 maximum pressure valve (Fig. 13), located on the
hydraulic oil power unit, will trip if the lift is
overloaded.
Fig. 13
◆If the lift reaches to the maximum height, the up limit
switch will stop the lifting. (Fig.14)
Fig. 14
◆Keep both cables in balance during raising or
lowering. (Fig. 15)
Fig. 15

USER’S MANUAL
◆If the hydraulic cylinder breaks, the safety wedges
will trip (Fig. 16), located inside the posts. The
wedges are pushed by the spring and immediately stop
the carriage preventing their descent.
structure. During this phase, the operator must remain in
the command zone. (Fig. 17)
Fig. 16
◆If the moving part exceed its travel distance, on the
upper part of the command post there is one limit
switch and is usually set working by the “actuator”
(Fig. 14) on the command side carriage. If the first
limit switch did not work, the second one would trip
after 3sec of carriage run.
◆In case of total breakdown of the limit switches, the
carriage will stop a few millimeter higher. Because the
hydraulic cylinders come to end stroke, will cause the
maximum pressure valve (on hydraulic unit) to trip.
Fig. 17
3.6.2 RISK OF CRUSHING (PERSONNEL)
When the platform and the vehicle are descending,
personnel are prohibited from entering the area beneath the
moving parts of the lift. (Fig. 18) The lift operator must not
start the maneuver until it has been clearly established that
there are no persons in potentially dangerous positions.
3.6 RISKS OF PERSONS
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.
3.6.1 RISK OF CRUSHING (OPEARATOR)
Possible if the operator controlling the lift is not in the
specified position at the command panel. When the
platform and the vehicle are descending, the operator must
never be partly or completely underneath the moving
Fig. 18
3.6.3 RISK OF IMPACT
Caused by the parts of the lift or the vehicle that are
positioned at head height. When, due to operational reasons,
the lift is immobilized at relatively low elevations (less
than 1.75m from the ground) personnel must be careful to
avoid impact with parts of the machine not marked with
special hazard coloring. (Fig. 19)
