peratures between –25°C to +60°C for Ex, –25°C to +80°C for non-Ex and –25°C
to +60°C for non-Ex as modulating actuators are filled with oil according to the table
below. The indicated oil filling applies to open-close and modulating actuators.
WARNING
Danger of explosion due to impermissible heating up caused by oil leak-
age!
Death or serious injury.
à The seals must be replaced in case of leakage.
à Refill the correct quantity of oil.

1) Applies to actuators with planetary gearing and brake motor.
For other temperature ranges, the oil filling may deviate. The pertaining data can be
requested from the manufacturer.
Ensure leak tightness of the device by inspections at regular intervals. Pay special at-
tention to the following issues:
• Oil leakage and handwheel hub
• Oil leakage at joints of the housing
• Oil leakage at seals of hollow shaft
• Oil leakage at radial seals in limit switch and control compartment

Cleaning
Clean the actuator using conventional soap solutions (alkaline solutions). To avoid
heat accumulation or excessive surface temperatures, motor cooling fins must never
be covered.
WARNING
Risk of explosion by electrostatic discharge!
Death or serious injury.
à All outer actuator parts e.g. painted surfaces, indicator glass, labels, etc. may only
be cleaned using a moist cloth.
à The device must be equipped with an appropriate label which must be readable at
all times!
WARNING
Danger of explosion due to impermissible heating up caused by wet
painting layer!
Death or serious injury.
à It is not permitted to repaint the actuator!
NOTICE
Residues of conductible foreign particles within the actuator!
à Use of compressed air for cleaning the actuator is not permitted!
