Maintenance section
The maintenance operations are the absolute prerogative of
professional operators and specialised technicians, in compliance
with the requirements of Machinery Directive 2006/42/EC and
subsequent updates.
As routine maintenance, the following checks/operations must be carried out
once a month
:
Visually check the entire machine to make sure that the structures are not deformed
or cracked.
Check the welding and the proper functioning of the safety devices.
Make sure the machine ascends and descends smoothly.
Check that the connecting pipe between the pump and the hydraulic cylinder does not
have cracks or unusual deformations, otherwise replace it by following the installation
operations of the pump (‘Commissioning’).
If necessary, add hydraulic oil to the pump by using the special level plug. Use
MOTOREX COREX HLF-D 32 hydraulic oil or equivalents.
8.1
Lubrication
Check and grease the scissor sliding guides frequently.
Lubricate the pins and moving parts at least once a month. In case of continuous use, lubricate
every 15 days.
8.2
Bleeding of the hydraulic circuit
To carry out the bleeding of the hydraulic circuit follow the steps:
1-
Raise the platform using the ascent button to the maximum mechanical safety position;
2-
Unlock the safety bar, then use the descent button to lower the platform;
3-
Repeat the operations from points 1) and 2) a few times to eliminate any air bubbles in
the hydraulic circuit.
Once performing these operations, the platform will ascent properly. If, after performing the
previous operations, the platform does not lift properly, repeat the operations from points 1)
and 2).
