Extraordinary Maintenance
If there are leaks in the hydraulic cylinder, or a malfunction in the mechanical components,
or in case of scheduled preventive maintenance, the actuator must be disassembled and
seals must be replaced with reference to the following general sectional drawing and
adopting the following procedures.
5.2.1
Replacement of Cylinder Seals
(refer to Figure 22, Section 7.2)
NOTICE
Before carrying out any maintenance operation, it is necessary to close the hydraulic feed
line and exhaust the pressure from the actuator cylinder and from the control unit to
ensure safety of maintenance staff.
!
WARNING
If the actuator can be operated, it is essential to take it to fail-safe position with the spring
totally extended.
HLAS-C does not need lubrication during its life. However, it’s possible to utilize the
following grease during special maintenance operations, for example, to lubricate the
spring's surface inside spring cartridge.
