Up to 3 crates may be stacked one upon the other on lorries or in containers if property positioned
and provided they are restrained to prevent falling.
OPENING THE CRATES
When the crates arrive, check that the machine has not been damaged during transport and that all
parts listed are present. The crates must be opened using all possible precautionary measure to
avoid damaging the machine or its parts. Make sure that parts do not fall from the crate during
opening.
DISPOSAL OF CRATES
The crates may be reused or recycled.
INTRODUCTION WARNING
This manual has been prepared for workshop personnel expert in the use of the lift (operator) and
technicians responsible for routine maintenance (maintenance fitter): read the manual before carrying
out any operation with the lift and /or the packing. This manual contains important information
regarding:
THE PERSONAL SAFETY OF operators and maintenance workers
LIFT SATETY
THE SAFETY OF LIFTED VEHICLES
Express the rated load is 4000kg，don’t allow the lift load weigh excess 4000kg.
This symbol express attention should be taken for electrical hazards
CONSERVING THE MANUAL
The manual is an integral part of the lift, which it should always accompany even if the unit is
sold .The manual must be kept in the vicinity of the lift in an easily accessible place so that the
operator and maintenance staff must be able to locate and consult the manual quickly at any time.
ATTENTIVE AND REPEATED READING OF CHAPTER 3, WHICH CONTAINS IMPORTANT
INFORMATION AND SAFETY WARNINGS, IS PARTICULARLY RECOMMENDED.
Lift rack has been designed and built in compliance with the following:
4000kg

LAW S
The lifting, transport, unpacking, assembling, installation, starting up, initial adjustment and testing,
EXTRAORDINARY maintenance, repair, overhauls, transport and dismantling of the lift must be
performed by specialist personnel from the LICENSED DEALER or an SEVICE CENTRE authorized
by the manufacturer (see authorized dealer on frontispiece).
The manufacturer declines all responsibility for injury to persons or damage to vehicles or objects
when any of the above mentioned operations have been performed by unauthorized personnel or
when the rack has been subject to abuse.
This manual indicates only the operative and safety aspects that may prove useful to the operator
and maintenance works better understanding the structure and operation of the lift and for best use of
the lift.
In order to understand the terminology used in this manual, the operator must have specific
experience in workshop, service, maintenance and repair activities, the ability to interpret correctly
the drawings and descriptions contained in the manual and be acquainted with the general and
specific safety rules relevant to the country in which the machine has been installed.
The same applies to the maintenance fitter, who must also possess specific and specialized
knowledge (mechanical, engineering) needed to perform the operations described in the manual in
complete safety.
The words “operator” and “maintenance fitter” used in this manual are construed as follows:
OPERATOR: person authorized to use the lift.
WORKING CONDITIONS：1、Regarding ambient temperature shall be 5-40℃.
2、Regarding humidity shall be 30-95%.
3、Regarding transportation and storage temperature shall be
between25-55℃，and short period no exceeding 24 hours at up to
70℃.
4、Regarding installation altitude max 1000m.
MAINTENANCE FITTER: person authorized for routine maintenance of the lift.
The end user can only use the machine in correct way as defined in instruction.
Loose clothes shall not be used protection cap shall also be used for long hair person, etc.
The end user should provide the MSDS (Material Safety Data Sheet) at easy accessible place when
providing lubrication.

CHAPTER 1 DESCRIPTION OF THE MACHINE
The 2-post electro-hydraulic lift is a fixed installation. This means that it is anchored to the ground and
built for lifting and positioning automobiles and vans at a certain height off the ground.
The lift consists of the following main parts:
1. Fixed structure (posts + upper beam);
2. Mobile units (carriages + arms);
3. Lift units (2 hydraulic cylinders + power unit);
4. Control box;
5. Safety devices;
Figures 3 and 4 illustrate the various parts of the lift and the work areas reserved for use by operators
around the lift.
Command side: this side of the lift includes the area reserved for the operator to access the control
box.
Service side: this is the opposite side of the command side.
Front side: the side with the short arms.
Rear side: the side with the long arms.

1.1 FIXED STRUCTURE (FIG.4)
This structure consists of:
1. 2 posts, (service 15 and command 3 side post) built with bent steel plate. The base is welded to a
drilled plate to be anchored to the floor. The electric control box 4 and the hydraulic power unit 5
are attached to the command post. Inside each post are the moving parts to lift the vehicles. The
control panel and the hydraulic unit are fixed to the command post.
2. An upper beam 1,17 built with bent steel plate, connecting the upper posts with bolts.
Fig.4
1.2 MOVING UNITS (SEE FIG.4)
Each unit consists of:
1. Both carriage (10 and 14) built with welded steel plate. It joints by chain 8 and the steel wire 7,
and at the bottom to the lift arms by means of pins.
The carriage moves along the post, guided by plastic sliding pads, located inside the post itself.
2. Two telescopic arms, one long (13) and one short (12), built with tubular steel with a pad at each
end that can be height adjusted to hold the car and on the opposite side the carriage connection
hole.
