* Make sure the axis is horizontal and not offset.
* Please put a stopper separately so that it does not open and close above the angle of motion.
* Do not use it outside. Please confirm that the enclosure has sufficient strength and rigidity.
* When using the internal specification, check the position of the torque adjustment screw so that the screw can be rotated with the enclosure and the lid attached.
* If you apply excessive force in the opening direction, the product will load, so please prepare a stopper separately.
