Intended Use.................................................................................................................................. 5
General Safety Instructions............................................................................................................ 5
2.1 Intended Use
The M-228 / M-229 is a laboratory device as defined by DIN EN 61010-1. It is intended to be
used in interior spaces and in an environment which is free of dirt, oil, and lubricants.
In accordance with its design, the M-228 / M-229 is intended to be used for positioning,
adjusting and shifting loads in one axis at various velocities.
It is only possible to use the M-228 / M-229 as intended when it is installed, and only with a
suitable controller (p. 12). The controller is not included in the scope of delivery of the M-228 /
M-229.
2.2 General Safety Instructions
The M-228 / M-229 is built according to state-of-the-art technology and recognized safety
standards. Improper use can result in personal injury and/or damage to the M-228 / M-229.
Use the M-228 / M-229 for its intended purpose only, and only when it is in perfect
technical condition.
Read the user manual.
Eliminate any malfunctions that may affect safety immediately.
The operator is responsible for the correct installation and operation of the M-228 / M-229.

2.2.1 Organizational Measures
User manual
Always keep this user manual together with the M-228 / M-229.
The latest versions of the user manuals are available for download (p. 3) on our
website.
Add all information from the manufacturer to the user manual, for example
supplements or technical notes.
If you give the M-228 / M-229 to a third party, include this user manual as well as other
relevant information provided by the manufacturer.
Do the work only if the user manual is complete. Missing information due to an
incomplete user manual can result in minor injury and damage to equipment.
Install and operate the M-228 / M-229 only after you have read and understood this
user manual.
Personnel qualification
The M-228 / M-229 may only be installed, started, operated, maintained, and cleaned by
authorized and appropriately qualified personnel.
2.2.2 Safety Measures During Installation
A cable break leads to a failure of the linear actuator.
Install the linear actuator so that the cable is not bent too strongly or crushed during
operation.
Lateral forces that affect the pusher of the linear actuator increase the friction on the internal
drive components. Increased friction impairs the motion of the pusher and increases wear on
the drive components.
Avoid lateral forces on the tip and on the pusher of the M-228 / M-229.
The motion of the pusher can be hindered by a mounting nut that has been tightened too
strongly. This reduces the positioning accuracy.
Do not overtighten the nut (torque ≤15 Nm).
