1. The gourd should be cleaned and coated with antirust grease after use, and stored in a dry place to prevent the hand-pulled gourd from rust and corrosion due to damp.

2. The maintenance and overhaul should be carried out by those who are familiar with the hoist mechanism. The hoist parts should be cleaned with kerosene, and the gear and bearing parts should be lubricated with butter to prevent the machine from being disassembled and assembled at will.

3. After cleaning and maintenance, the gourd shall undergo no-load test to confirm normal operation and reliable braking before delivery.

The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and heavy weight falling.

5. The roller of the left and right bearing of the lifting sprocket of the hand chain pulley can be attached with butter to the bearing inner ring that has been pressed on the axle journal of the lifting sprocket, and then loaded into the bearing outer ring of the wallboard.

6. Chain when installing a brake parts, pay attention to the ratchet wheel gullet and pawl radical mesh is good, the spring of the ratchet control should be flexible, reliable and fit after the sprocket, clockwise hand chain, will ratchet, friction pressure on the brake block, the hand wheel counterclockwise, ratchet and there should be gaps between the friction plate.

7. For the convenience of maintenance and removal, one part of the hand chain is the open chain (no welding is allowed).

8. During refueling and the use of hand-pulled gourds, the friction surface of the brake shall be kept clean, and the braking force shall be checked frequently to prevent the brake failure from causing weight
