WARNING
Risk of injury as a result of undesirable rotary motion
If, with the motor switched on, you work in the rotational range of the motor, and the motor
undesirably rotates, this can result in death, injury and/or material damage.
• Always switch off the motor before working in the rotational range of the motor. Ensure
that the motor is in a completely no-voltage condition.
