Warning

Be careful when releasing the brake. Releasing carelessly may cause injury or damage
to the actuator body, workpiece or surrounding devices due to the slider or rod falling.

After releasing the brake, be sure to return the brake to the enabled status. It is very
dangerous to operate with the brake released. It may cause injury or damage to the
actuator body, workpiece or surrounding devices due to the slider or rod falling.
