1. DESCRIPTION

NOTE
lt is the main parts figures above. More detailed components and assembly please see
exploded view.
5. INSTALLATION
Connecting pipes
There are two pipes from the hydraulic pump as shown in the figure. (X) is a electric wire
and used for the safety lock. (Y) is a hydraulic oil pipe and used for the hydraulic
cylinders.

Enter hydraulic oi/
Remove the motor box off, and then turn the oil cap anti-clockwise to open the oil inlet.
Fill in the hydraulic oil 30# from the oil inlet as shown in the figure.
Oil inlet Oil inlet
NOTE
•Make sure that there is sufficient oil in the tank when the machine in working
•Do not overfill the oil tank, otherwise it may overflow when the oil warms up and
expands.
•Make sure that the oil tank cap is properly closed before working.
6. OPERATION
During all operations, keep hands and other parts of the body as far as possible from
moving parts of the machine. With necklace, bracelets and too large clothes, can be
dangerous for the operator.

Press the UP button,
the lift will go up
When the lift is working (lifting a car), remember:
any personnel do not get in the lift and the car, it could result in severe injury or
death!
Press the DOWN button,
the platform will go down
7. STORING
lf the machine has to be stored for a long time you should :
•Get down the platforms and no heavy object on them.
•Disconnect the machine from all power sources.

Page 10 of 17
•Grease all the parts that could be damaged if they dry out.
•Empty hydraulic oil tank and wrap the machine in a sheet of protective plastic to
prevent dust from reaching the internai working parts.
lf the machine has to work again after a long storing period, it is necessary to:
•put the oil into the tank again.
•restore the electric connection.
8. MAINTENANCE
PRECAUTIONS
WARNING
Maintenance must be carried out only by skilled personnel who are very familiar with the lift.
When performing maintenance on the lift, follow all the necessary precautions to prevent the lift from
being started accidentally:
1. Cut off the power and pull the plug out of the jack.
2. While maintenance is being performed on the machine, always keep in mind all the main possible
risks and the safety instructions indicated in chapter 3 "safety risk of electric shock" at the machine
power supply terminal strip.
IT IS PROHIBITED TO PERRORM MAINTENANCE ON THE OIL CYLINDER. IT SHOULD BE
REPLACED WHEN DAMAGED.
IMPORTANT
1.Only use original spare parts and tools that are suitable for the job and in good condition;
2.Follow the maintenance schedule indicated in the manual: these frequencies are
indicative and must always be considered as general rules to be respected.
3.Good preventive maintenance requires constant attention and continuous supervision on the
machine. Quickly find the cause of any abnormalities such as excessive noise, overheating, leaking
fluids, etc.
Special attention is required for:
1. The condition of lifting parts (cylinder, power unit);
2. Safety devices (oil cylinder and safety wedges)
To perform maintenance correctly, reter to the following documents supplied by the lift
manufacturer:
1. Complete functional diagram of the electric equipment and auxiliary equipment indicating the power
supply connections
2. Hydraulic diagram with lists of parts and max. Pressure values

3. Exploded drawings with the data needed to order spare parts
PERIODIC MAINTENANCE
OPERATION FREQUENCY
To keep the lift working at full efficiency, follow the indicated maintenance schedule. The manufacturer
will not be responsible and will not honor the warranty as a result of
non-compliance with the instructions indicated above.
NOTE
The frequency indicated refers to normal operating conditions; different frequencies will apply to
particularly server conditions.
ALL MAINTENANCE OPERATIONS MUST BE PERFORMED WITH THE LIFT STOPPING OR THE
MAIN SWITCH PLACED AT "O".
When after the machine has been installed, check:
1 That the opposite carriages arms are at the sarne leve!
2 The power unit oil leve!. Add oil up to the right leve!, if necessary
3 EVERY MONTH
10. HYDAULIC POWER UNIT
1 Check the oil leve! in the tank, using the special dipstick, which is attached to the filler cap. lf
necessary, add oil through the cap to reach the required leve!. For the type of oil, see
''TECHNICAL SPECIFICATIONS".
2 After the first 40 hours of operation, check the press oil contamination leve!. (Clean the filter and
replace the oil if there is a high contamination leve!).
HYDRAULIC CIRCUIT
Check that there are no oil leaks in the circuit between the power unit and cylinder and in the cylinder
itself. ln this case, check the condition of the gaskets and replace them, if necessary.
HYDRAULIC PUMP
Under normal operating conditions, check that there is no change in the noise in the motor and gear
pump and check that the relative bolts are properly tightened.
SAFETY SYSTEMS
1 Check the operating condition and efficiency of the safety devices .
2 Use a torque wrench to check that the post bases anchor bolts screws are properly tightened to
the ground as well as the connection bolts.
3 Clean and lubricate the carriage side runners and guides.
4 Check that all screws are tightened

5 Gheck that the locking system works properly.
6 Grease all the moving parts.
EVERY 6-MONTHS...
HYDRAULIC
Gheck the contamination or aging levei of the oil. Gontaminated oil is the main cause of malfunctions
of the valves and leads to a brief service life of the gear pumps.
EVERY 12- MONTHS
General check: visual inspection of all structural parts and mechanisms to guarantee that there are no
problems or abnormalities.
Electric plant: skilled electricians (contact the service center) should test the electric plant, including
the motor of the power unit, and contrai box.
HYDRULIC PLANT OIL
Replace the oil, following the instructions listed below:
1. Lower the lift to the minimum height (on the ground)
2. Make sure that the hydraulic cylinder is at the end of its travei
3. Disconnect the power supply to the lift rack.
4. Drain the oil from the hydraulic circuit, unscrewing the plug located at the bottom of the power unit
reservoir.
5. Glose the drain plug
6. Fill the hydraulic station oil cylinder with oil throng the plug located at the top of the hydraulic
station.
The oil must be filtered.
Oil characteristics and types are reported in the technical specifications.
1. Glose the filler plug
2. Energize the lift
3. Go through two or three up-down cycles (for a height about 20-30 centimeters) to insert oil into the
circuit.
When changing the oil: use only recommend oil or the equivalent; do not use deteriorated oil that has
been in the warehouse for an extended period of time.
AFTER EAGH MAINTENANGE OPERATION, THE MAGHINE MUST RETURN TO ITS INITIAL
GONDITIONS, INGLUDING THE DISASSEMBLEED PROTEGTION AND SAFETY DEVIGE.
To ensure good maintenance, it is important:
1. To sue only tools that are suitable for the job and original spare parts
2. Follow the minimum maintenance schedule as indicated
