Tightening the screws with a higher torque than recommended may cause a malfunction, whilst the tightening with a lower torque can cause the displacement of the mounting position or in extreme conditions the actuator could become detached from its mounting position. 14. Do not operate by fixing the table and moving the actuator body. 15. The belt drive actuator cannot be used vertically for applications. 16. Check the specifications for the minimum speed of each actuator. Otherwise, unexpected malfunctions, such as knocking, may occur. 17. In the case of the belt drive actuator, vibration may occur during operation at speeds within the actuator specifications, this could be caused by the operating conditions. Change the speed setting to a speed that does not cause vibration. oA L L Series LEL Electric Actuator/Guide Rod Slider Specific Product Precautions 2 Be sure to read before handling.
