Operating instructions for actuators type AB
OM-ENGLISH-AB-V2.05-2017.06.28

5 Maintenance

No maintenance work must be undertaken unless the actuator has been switched to IDLE.
(Switching on during maintenance must be rendered impossible.) Following start-up, the ac-
tuators are ready for use. The actuator is standardly filled with grease (oil filling upon customer's
request).
Regular Maintenance Inspection:
Beware of increased running noises. After every three months of non-operation, activate the actuator.
With actuators having output types A, B and C according to DIN 3210-Standard (types A, B1, B2 and
C according DIN ISO 5210-Standrad), re-grease them at the lubricator nipple at least every six months
(see section 7.3, page 14).
As there is no specific restriction on the installation position (see section 1.4, page 4), there is no oil
gauge and no oil drain plug in the main casing.
The lubricant changing of the main casing must be made about the hand wheel.
Depending on the frequency of operation,
change the grease (oil),
renew the seals and
check all roller bearings and the worm-wheel unit and replace them, if necessary.
after every 10,000 to 20,000 hours of operation (approximately every five years - see section 7.5,
page 14).
See the Table of Lubricants (see section 7, page 13) for the types of oil and grease to be used.
Check the cable glands at regular intervals (annually) for tightness of the cables and retighten if
necessary.
If the visual inspection (eg. dust or water penetration) indicates that the effectiveness of the Sealing elements
of the cable entry has suffered damage or aging, such elements have to be replaced preferably by using the
original spare parts from the manufacturer of the equipment or through cable entries of comparable quality as
well as the same ex- or IP protection class.

6 Spare parts

When ordering replacement parts, the fabrication number of the actuator must be given (see section 1.1,
page 3). For actuator replacement parts use our exploded diagram 80.B.1.6. and our Replacement Parts List
80.B.1.7. Replacement parts lists for other structural components upon request.
