in the control station as the diagrams illustrated.
As the diagrams illustrated: The presence of
persons inside the danger zone indicated is strictly

Installation/Operation & Maintenance Manual
HXL6128 MID-RISE SCISSOR LIFT
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).
Fig. 3
DO NOT USE THE LIFT WITHOUT
PROTECION DEVICES OR WITH THE
PROTECTION DEVICES INHIBITED.
FAILURE TO COMPLY WITH THESE
REGULATION CAN CAUSE SERIOUS INJURY TO
PERSONS, AND IRREPEARABLE DAMAGE TO
THE LIFT AND THE VEHICLE BEIN LIFED.
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.
GENERAL PRECAUTIONS

Installation/Operation & Maintenance Manual
HXL6128 MID-RISE SCISSOR LIFT
Chapter 3 SAFETY
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 zone when vehicles
are being lifted. (Fig. 3)
● Make sure the vehicle is positioned correctly.
(Fig. 4)
Fig. 4
● 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 are no person on the
platforms during up and down movements and
during standing.
GENERAL RISKS FOR LIFTING OR DESCENT:
The following safety equipments is used to protect
over loading or the possibility of engine failure.
In the condition of over loading, the over-falling
valve will open and directly return oil to the oil tank.
(Fig. 5)
Fig. 5 Over-falling Valve
Each bottom of oil cylinder is equipped with
antiknock and locked valve. When the oil pipe is
burst in the circuit of hydraulic pressure, the relevant
antiknock and locked valve will work and limit the
speediness of platform. (Fig. 6)
Fig. 6
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. (Fig. 7)

Installation/Operation & Maintenance Manual
HXL6128 MID-RISE SCISSOR LIFT
Fig. 7
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. (Fig. 3)
RISK OF IMPACT
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, personnel must be careful to avoid
impact with parts of the machine not marked with
special colors.
Fig. 8 Risk of Impact
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
Caused by lubricant contamination of the floor
around the lift. The area beneath and immediately
surrounding the lift and also the platforms must be
kept clean. Remove any oil spills immediately.
Fig. 9 Risk of Slipping

Installation/Operation & Maintenance Manual
HXL6128 MID-RISE SCISSOR LIFT
RISK OF ELECTRIC SHOCK
Risk of electric shock in areas of insulated and
shattered electric equipments.
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 IMAPPROPRIATE
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.
