”.
◆
After the first 40 hours of operation, check if the
conveys or filter is clogged and the oil contamination
level. (Clean the filter and replace the oil if there is a
high contamination level.)
HYDAULIC CIRCUIT
Check that there are no oil leaks in the circuit between the
power unit and cylinder and in the cylinder itself. In this
case, check the condition of the gaskets and replace them,
if necessary.
6.2.3 EVERY 3-MONTH
HYDAULIC PUMP
Under normal operating conditions, check that there is no
changes in the noise in the power unit pump and check that
the relative bolts are properly tightened.
SYNCRONOUS SYSTEMS
◆
Check the operating condition and efficiency of the
safety devices (as described at pages 6, 7) and the
wear on the safety wedges and relative hinge pins. Oil
the pins on the safety wedges. In case of excessive
wear, replace the safety wedges and/or pins.
◆
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.
◆
Clean and lubricate the carriage side runners and
guides.
◆
Check that all screws are tightened
◆
Check that the arm locking system works properly.
◆
Grease all the moving parts.
6.2.4 EVERY 6-MONTH
HYDRAULIC
Check the contamination or aging level of the oil.
Contaminated oil is the main cause of malfunctions of the
valves and leads to a brief service life of the gear pumps.
SYNCHRONOUS CABLE
Check the pulleys and pulley races conditions. Control the
cable wear by checking diameter, possible broken wires,
other damages or relevant changes. With a paintbrush
grease the cable in order to avoid corrosion or breakage
due to oxidation.
6.2.5 EVERY 12-MONTH
General check: visual inspection of all structural parts and
mechanisms to guarantee that there are no problems or
anomalies.
Electric plant: skilled electricians (contact the service
center) should test the electric plant, including the motor of
the power unit, cables, and limit switch.
HYDRULIC PLANT OIL
Replace the oil, following the instructions listed below:
◆
Lower the lift to the minimum height (on the ground).
◆
Make sure that the hydraulic cylinder is at the end of
its travel.
◆
Disconnect the power supply to the lift rack.
◆
Drain the oil from the hydraulic circuit, unscrewing
the plug located at the bottom of the power unit
reservoir.
◆
Close the drain plug.
◆
Fill the power unit with oil throng the plug located at
the top of the power unit reservoir.
The oil must be filtered:
◆
Oil characteristics and types are reported in the
technical specifications (Chapter 2, page 3)
◆
Close the filler plug
◆
Energize the lift rack
◆
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
