2 GENERAL SAFETY AND ACCIDENT-PREVENTION RULES
PAY CAREFUL ATTENTION TO THE DANGER SIGNS WHEN THEY APPEAR IN THIS MANUAL. THERE ARE THREE LEVELS OF
DANGER SIGNS.
DANGER
This sign warns that, if the operations described are not carried out correctly, the user is exposed to serious risks which may result
in injuries, death or long-term damage to his health.
WARNING
This sign warns that, if the operations described are not carried out correctly, the user is exposed to risks which may result in
injuries, death or long-term damage to his health.
CAUTION
This sign warns that, if the operations described are not carried out correctly, the lift risks being damaged.

REV 02 OCT 2020 JLT4500-IOM-F 6
DANGER
In order to pre ent risks to third parties and/or damages to things, before any operation takes place, the user shall make sure that
there are not things or persons close to the lift before starting any working cycle.
DANGER
Before using the lift, make sure that required protecti e apparels are used (protecti e glo es, goggles…).
This manual is addressed to the user of the lift and to the person who has the responsibility of its correct and safe use.
Read carefully the warnings contained in this manual, which is also supplying the indications for a correct and hazard free use of the lift.
Familiarize with the controls and the operations required for the use of the lift in emergency conditions. Always keep this manual by the lift, in
order to consult it in the event of any future possible need. The manual shall follow the lift in case it is sold.
DANGER
Immediately point out any problem or breakdown, including e entual defects detected on the control unit and/or on the hydraulic
and electric connections to the owner of the lift or to the person in charge of its safe use.
The user in charge of the lift shall be a person fit for the job and shall ha e a perfect knowledge of
how the system's equipment is to be used. He shall follow the instructions pro ided to guarantee
their safety and the safety of others
3 WORKPLACE ENVIRONMENT
Workplace environment must be clean and in orderly conditions. In particular, hazardous areas must be
duly delimited.
The field of motion of the load and of the load carrying devices shall be free of obstructions.
The work tools and materials shall not be left on the lifts (or in places where these may interfere
with its mechanical movements) or kept in places where they may fall and hence cause
accidents.
Each tool must be used exclusively for the use it was designed for
and in the most suitable way.
Never use tools that are deteriorated.
Do not clean nor touch any mechanical part while in motion.

REV 02 OCT 2020 JLT4500-IOM-F 7
The use of loose-fitting working cloths (e.g. scarves, button-down shirts, etc.) can be hazardous.
Always wear close-fitting garments.
Any oil or grease on the floor shall be removed immediately to prevent any risk of slipping or falling.
4 RESIDUAL HAZARDS
DANGER
It is mandatory to the owner of the lift and/or the person in charge of it, to supply to the final user all the necessary information and
aids to the safeguard of its physical health.
All the various stages - Designing, Construction, Selection of the sub-contractors and Final Inspection - involving the manufacturing processes
of the JohnBean JLT4500 two post vehicle lift were carried out by JohnBean Manufacturing with the utmost care and attention to assure
compliance of the product with the strictest safety standards through its high mechanical and engineering quality.
It is, however, necessary to specify that, notwithstanding:
• the attention taken in the designing phase;
• the care and control given to the manufacturing process;
The lift object of this manual has, however, some risks that, for the specific type of job to execute, cannot be completely eliminated with the
aid of security systems. Such risks are later on listed. It is absolutely necessary therefore that the operator is informed of such risks and that
uses the lift with the maximum precaution. Familiarize with the controls and the operations described in this manual to use the lift in safe
conditions.
Always keep this manual together with the lift so as to make immediately possible any future consultation. The manual shall follow the lift in
case of its sale. A safe use is only guaranteed for the functions listed in this manual.
DANGER
Ne er use the lift before ha ing erified that all the emergency de ices are installed correctly and operati e.

REV 02 OCT 2020 JLT4500-IOM-F 8
DANGER
The operator is considered an integral part of the control system with the lowering al e and lock release. During any lowering, the
operator must erify no obstruction under the lift. If any fault occurs during lowering, the operator must immediately stop the
lowering command upon indication of any problems.
Since the operator is acti ely engaged in the operation of the lift, the risk is negligible.
4.1 CRUSHING HAZARD
This hazard is present during the lowering operation of the lift.
DANGER
In order to pre ent risks to third parties and/or damages to things, before any operation takes
place, the user shall make sure that there are no things or persons in the field of motion of lift
before and while operating it.
Each lifting cylinder is equipped with a flow limiting device that controls the lowering speed in the event of a failure in the hydraulic circuit (e.g.
if a hose is cut).
DANGER
The flow limiting de ices are setup and tested at the factory to operate in standard working conditions (20°C and 46 Cst oil).
The setup of the de ice can be hea ily affected by the working conditions (including temperature, oil iscosity and humidity).
If the lift is to be used in different working conditions from the standard design criteria, then the flow limiting de ice setup shall be
erified and appro ed by authorized personnel. A wrongly setup flow limiting de ice could generate a serious hazard.
The lift is equipped with a mechanical safety locking device that prevents the possible accidental fall of the load due, e.g., to a mechanical
failure and/or the accidental breach of a hydraulic hose. The safety locking points are placed in such way that the maximum allowed vertical
fall is limited to 98 millimeters.

REV 02 OCT 2020 JLT4500-IOM-F 9
DANGER
Before standing under the raised ehicle, make sure that both the load lifting are held by the safety locks.
4.2 HAZARD OF THE VEHICLE TO FALL FROM THE LIFT
This hazard is present during both the raising and the lowering phases. The user shall make sure that the vehicle is correctly positioned on
the arms of the lift, as per the requirements given in § 5,5, and that all the actions are taken at a reduced speed.
DANGER
Do not support the ehicle with any kind of de ice while lifting/lowering the lift.
DANGER
Do not shake the ehicle while supported on the lift.
DANGER
Do not lift only one side of the ehicle.
4.3 HAZARD OF OVERTURNING OF THE VEHICLE DUE TO INSTABILITY OF THE LOAD
This hazard is present during both the raising and the lowering phases. The user shall make sure that the vehicle correctly is positioned on
the arms of the lift, as per the requirements given in § 5,5, and that all the actions are taken at a reduced speed.
DANGER
Do not raise the lift if the ehicle's weight is not properly balanced on the load supporting de ices.
Before beginning the working cycle, erify the correct disposition of the ehicle on the arms of the lift by stopping
the lifting process immediately after the ehicle has lost contact with the ground. Make sure that the ehicle is
properly balanced on the supporting arms and abort immediately any operation on the lift if the load
appears to be unbalanced.

REV 02 OCT 2020 JLT4500-IOM-F 10
4.4 ELECTRIC HAZARD
This hazard is present if the electric connections are not compliant to the applicable safety local norms.
ATTENTION
Before connecting the lift to the electric line, erify that the line itself is completely compliant to the enforced norm.
Also make sure that the electric line can supply the needed power and that:
•there is a properly working grounding circuit
•there is a properly working protection circuit
ATTENTION
Before plugging the lift to the main power supply or before any maintenance work, make sure that the main switch of the power
supply is set to the OFF (0) position.
4.5 GENERIC HAZARDS
Any other use or operation not in compliance with this manual could cause damages to the user and or to the lift.
An un-forecasted and unexpected use alters the technical characteristics for which the lift has been designed and manufactured and could
then compromise its correct and safe use.
DANGER
The lift was designed for indoor operation only. Do not install and/or use this lift outdoor.
DANGER
It is absolutely forbidden to raise persons with this lift.
It is forbidden for people to stand on the load or load carrying de ices when they are raised.
