Maintenance
The actuators are lubricated with plastic consistent lubricants or gearbox oil PP 80.
Actuators with plastic grease
Types of lubricants and their use are specified in table below. Lubricant included inside the supplied actuators is
intended for their entire service life.
Lubricant does not need to be changed and its quantity does not need to be checked over the entire service life of actuators.
Actuators with grease are identified with label stating “FILLED WITH PLASTIC GREASE”, located on the power box
on the hand wheel side.
Note:
Lubricant CIATIM 221 is used for lubricating points of friction on rubber sleeves with metallic surfaces, roller brake
and hub of outer gear in planetary differential in 52 020 type actuators (in points of friction with shaft and on surfaces).
Actuators with oil charge
If the oil does not flow from the gearbox due to bad sealing, the charge is stable. Exchange oil after 500 hours of
actuator operation, however, no longer than after 10 years. Oil has to be checked on quarterly basis. The level of oil
should be as high as the filling hole. The actuator is filled with PP 80 motor-car gearbox oil.
Oil quantities for individual type numbers:
Adapter of actuator 52 026 is to be filled with fat PM MOGUL LV2-3, quantity: 3 kg.
11. TROUBLESHOOTING
1. The actuator in its end position, does not start up, motor humming – check for a missing phase.
If slider is jammed and if you cannot move it nor by hand wheel neither by motor, actuator must be dismounted and
the lock must be released mechanically.
2. Upon actuator start-up from end position of the output shaft, actuator stops voluntarily.
It must be made sure that recess in the switching wheel
(Figure 2)
stops in the end position of the output
wheel of actuator
(after torque switch tripping)
prior to running onto advance mechanism 21
(Figure 3).
This can
be achieved by turning actuator output shaft to a suitable position while coupling actuator with valve, or by
turning switching wheel to suitable position relative to output shaft. For this reason, the switching wheel has two
grooves for a connecting key. Additionally, the switching wheel can also be reversed.
