CHAPTER 9 - MAINTENANCE
Only trained personnel who knows how the lift works, must be allowed to service
the lift
.
To service properly the lift, the following has to be carried out:
•
use only genuine spare parts as well as equipment suitable for the work required;
•
follow the scheduled maintenance and check periods shown in the manual;
•
discover the reason for possible failures such as too much noise, overheating, oil blow-by,
etc.
Refer to documents supplied by the dealer to carry out maintenance:
o
functional drawing of the electric and hydraulic equipment
o
exploded views with all data necessary for spare parts ordering
•
list of possible faults and relevant solutions.
Before carrying out any maintenance or repair on the lift, disconnect the power
supply, padlock the general switch and keep the key in a safe place to prevent
unauthorized persons from switching on or operating the lift.
9.1 ORDINARY
MAINTENANCE
The lift has to be properly cleaned at least once a month using self-cleaning clothes. Lubricate all
pivot pins at least once a week.
The use of water or inflammable liquid is strictly forbidden.
Be sure the rod of the hydraulic cylinders is always clean and not damaged since this may result in
leakage from seals and, as a consequence, in possible malfunctions.
9.2 PERIODIC
MAINTENANCE
Every 3 months
Hydraulic circuit
check oil tank level; refill with oil, if needed;
check the circuit for oil leakage.
check seals for proper conditions and replace them, if
necessary;
Foundation bolts
check bolts for proper tightening
Hydraulic pump
verify that no noise changes take place in the pump
when running and check fixing bolts for proper
tightening
Safety system
check safety devices for proper operation
Every 6 months
Oil
check oil for contamination or ageing. Contaminated oil
is the main reason for failure of valves and shorter life of
gears pumps
Every 12 months
General check
verify that all components and mechanisms are not
damaged
Electrical system
a check of the electrical system to verify that motor,
limit switch and control panel operate properly must be
carried out by skilled electricians
Oil
empty the oil tank and change the hydraulic oil
