| Maintenance & Inspection |
| Lifting Load: Ensure area is clear of people and obstruction, and begin lifting by slowly pulling hand chain in "U" direction.
Lowering Load: Ensure area is clear of people and obstructions, and reverse lifting procedure. It may be necessary to apply extra initial effort to release
friction between brake components.
 Operating instruction
- To lift up, pull on the right chain fall.
- To lower, pull on the left chain fall.
- Before lifting inspect carefully the hooks, the load chain, the brake device and lubrication of the block. For safe
operation you must keep six rules as following.
1. Don't lift load exceeding the rated capacity of the chain block.
2. Don't use the block chain as a sling.
3. Don't use when the chain is kinking.
4. To avoid accidents working or passing under a lifting load is strictly forbidden.
5. In case of the hand chain fails to move. Don't use undue force. Stop operation and proceed inspection of the chain block.
6. Only use to lift vertically, do not use to drag loads.
