Before you start to install the actuator make sure that the delivery status corresponds to the
ordered status and to the intended use.
• Check the oil level when installing the device in positions other than IMB 3.
• Did you fasten the separately delivered venting plug in the uppermost bore (depending on
the mounting orientation)?
• Make sure that the motor and the connection chambers are free of dirt, moisture and
corrosion.
