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.
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.

7
Installation/Operation & Maintenance Manual
GM - 6150H 2-POST LIFT
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.
3.2 RISKS OF ELECTRIC SHOCK
Specific safety notice affixed to the lift in areas
where the risk of electric shock is particularly high.
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.
Fig. 11 Risk of Vehicle Fall
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.

Installation/Operation & Maintenance Manual
GM - 6150H 2-POST LIFT
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
◆ 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.
Fig. 16

9
Installation/Operation & Maintenance Manual
GM - 6150H 2-POST LIFT
◆ 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.
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 structure. During this phase,
the operator must remain in the command zone.
(Fig. 17)
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.
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)
Fig. 19
3.6.4 RISK DUE TO VEHICLE MOVEMENT
Movement may be caused during operations, which
involve force sufficient to move the vehicle. (Fig. 20)
If the vehicle is of considerable dimensions or
weight, movement may lead to overload or
unbalancing. All measures must be taking to avoid
such an occurrence.

10
Installation/Operation & Maintenance Manual
GM - 6150H 2-POST LIFT
Fig. 20
3.6.5 RISK OF VEHICLE FALLING FROM LIFT
This risk could be caused by the incorrect
positioning on the arm disk support plates (Fig. 21)
or in incorrect position of the arm disk support plates
in relation to the lift.
Fig. 21
NEVER BOARD THE VEHICLE AND/OR TURN
THE ENGINE ON WHEN LIFT IS RAISED. (Fig. 22)
Fig. 22
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. (Fig. 23)
Fig. 23
3.6.6 SLIPPING
This risk may arise due to spillage of lubricants in
the surrounding area. (Fig. 24)
Fig. 24
ALWAYS KEEP THE AREA SURROUNDING AND
THE LIFT CLEAN BY REMOVING ALL OIL
SPILLS.
To avoid the risk of slipping, make use of the
recommended personal protection (anti-slip
footwear).
3.6.7 RISK OF ELECTRIC SHOCK
Risk of electric shock in areas of the lift housing
electric wiring. Do not use jets of water, steam (high
pressure wash units), and solvents or paint in the
immediate vicinity of the lift, and take special care to
keep such substances clear off the electrical
command panel. (Fig. 25)

Fig. 25
3.6.8 RISK OF COMPONENT FAILURE DURING
OPERATION
The manufacturer has used appropriate materials
and construction techniques in relation to the
specified 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 6
“MAINTENANCE” must be observed.
3.6.9 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. (Fig. 26) 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.
