The power unit oil level. Add oil up to the right
level, if necessary.
6.2.2 EVERY MONTH
HYDAULIC POWER UNIT
◆
Check the oil level, using the special dipstick,
which is attached to the filler cap. If necessary,
add oil through the cap to reach the required
level. For the type of oil,
see
Page 3
“
TECHNICAL SPECIFICATIONS
”.
◆
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 and control box.
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.
