7.1.2 Visual inspection
Check the entire servo actuator and all cables for exterior damage.
The radial shaft seals are subject to wear. Therefore, also check the servo actuator for
leakage during each visual inspection (lubricant leaks).
You can find more general information on radial shaft seals on our partner's Internet site at
http://www.simrit.de.
Check the mounting position, so that no foreign medium (e.g. oil) has collected on the
output flange.
Check whether the safety signs (see Chapter 2.8 "Safety signs") and the type plate (see
Chapter 3.1 "Name plate") are mounted and legible.
7.1.3 Checking the tightening torques
Check the tightening torque of the fastening screws on the servo actuator housing and at the
output flange.
The prescribed tightening torques can be found in Chapter 9.1 "Specifications for mounting
on a machine", Tables "Tbl-11", "Tbl-12"and "Tbl-13", and in Chapter 9.2 "Specifications
for mounting on the output side", Table "Tbl-14".
If, while checking the tightening torque, you discover that a screw can be further tightened,
follow the instructions in "Remounting the screw".
Remounting the screw
Loosen the screw.
Remove the glue residue from the threaded bore and the screw.
De-grease the screw.
Coat the screw with a threadlocker (e.g. Loctite
®
243).
Insert the screw and tighten it with the specified torque.
7.1.4 Cleaning
Clean the servo actuator using a clean, lint-free cloth.
If necessary, use a suitable fat dissolving but non-aggressive cleaning agent.
7.2
Startup after maintenance work
Clean the outside of the servo actuator.
Attach all safety devices.
Do a trial run before releasing the servo actuator again for operation.
Make sure that it is possible to remount the screw on the gearbox without
damaging the entire machine.
Pressurized air can damage the servo actuator seals.
Do not use pressurized air to clean the servo actuator.
