7.1 General Notes on Maintenance
NOTICE
Damage due to improper maintenance!
The M-228 / M-229 can become misaligned as a result of improper maintenance.

Do not loosen any sealed screws.
7.2 Lubricating the M­228 / M­229
Depending on the operating conditions and the period of use of the linear actuator, the
following maintenance measures are required.
Spreading lubricant

If you move the M-228 / M-229 over a small travel range (<20% of the entire travel
range) in continuous industrial operation, do a maintenance run across the entire travel
range every 2000 motion cycles.
Relubricating
Under laboratory conditions, it is only necessary to relubricate the linear actuator in exceptional
cases. For continuous industrial use, the lubrication intervals must be determined individually.

If you have any questions on relubricating, contact our customer service department
(p. 33).
