Actuator
Note: Before actioning any maintenance programme read the 'Safety information' in
Section 1.
6.1 General
Periodically check that all fasteners remain tight.
No routine maintenance is required, as the actuator is supplied with sufficient lubrication
for a normal working life. Depending on the severity of actuator operating conditions, periodic
replacement of the 'O' rings may be required. Spares are available - see Section 7.
6.2 Preventitive maintenance
6.2.1
We recommend a periodic inspection to check the actuator function.
6.2.2
Actuators must be operated at least once every six months.
6.2.3
Replace the 'O' rings, guides and washers if necessary.
6.3 Reasons for parts repair and replacement
Repair or replace the actuator components as soon as leakage is detected through the
upper 'O' ring (
16
) or lower 'O' ring (
7
) of the pinion, through the piston 'O' ring (
8
) or through
the 'O' rings (
11
) of the end caps.
