1, never overload, the weight of the goods shall not exceed the greatest range of scale.

2 shackle, hook scale (rings), hooks and hanging objects may not exist between the PIN lock, that is in the vertical direction of the contact surfaces should be at the center point location may not be stuck on the two sides contact, should have sufficient degrees of freedom.

3, the air runtime, lower end of hanging objects shall not be less than the height of a person, the operator should maintain a distance of at least 1 m and hanging objects. Below is strictly prohibited in the electronic crane scale is strictly prohibited to stand on, so as to avoid accidents.

4, is strictly prohibited using the sling group stayed to enhance objects.

5, when not working, hanging, rigging, lifting fixture hanging heavy objects are not allowed, and should be unloaded. To avoid permanent deformation of parts.

6, it is strictly forbidden to display the scale of impact.

7, crane scales to carry out regular inspection and maintenance, keep the crane scale clean, pay attention to Sun moisture-proof and dust-proof.

8, non-heat-resistant and explosion-proof or high temperature magnetic scale must not be used or explosive and strong magnetic field.

9, hanging there owed when the display indicates, to recharge it; when you’re not using for a long time, to be placed in a cool, dry and ventilated place, and charged on a regular basis.

10, snow or thunderstorms and other harsh environments to minimize the use of scale.

11, according to use, periodic calibration, maintenance and repair of the scale.
