12. OPERATION AND MAINTENANCE
Correct operation of actuators is determined by operational conditions and is usually limited to giving
impulses for the various functional tasks. In the event of power supply interruption, set the position of the
controlled valve by means of hand wheel. If the actuator is connected to automatic control circuit
(this does not
mean regulating operation),
we recommend you to install elements for remote manual control in the circuit so
that the actuator can be operated also in case of such automatic control circuit breakdown.
Operating personnel must ensure that the prescribed maintenance is carried out and that the actuator is also
protected against harming ambient impacts and weather conditions unspecified in section “Operating
Conditions”.
At the latest six months after actuator commissioning and subsequently at least once a year, the screws
connecting valve and actuator must be properly retightened. Screws must be tightened crosswise.
Lubrication
Consistent greases or gear oil PP80
(see Table 1 or 2)
are to be used for lubricating actuators.
Actuators with grease
Types and quantities of lubricants are specified in table below.
Lubricant included inside supplied actuators is intended for their entire service life. Lubricant does not need to be
exchanged 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 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 points of friction with shaft and on surfaces).
Actuators with oil filling
Once a year check oil level and refill oil when necessary. Exchange oil after 500 hours of actuator operation, however,
no longer than after 2 years. Actuator is filled with automotive gear oil PP 80 or with another oil with equivalent properties
(viscosity class 80W as per SAE /K 306a).
