1. After operation, clean the chain block from dim and keep it in a dry place from rust and corrosion.
2. Clean the chain block annually by purging the parts in kerosene and apply grease to them, it is advisable that the
cleaning work should be done by skilled hands.
3. “O” marks on the two disk gears should be aligned.
4. Stick the rollers of both left and right bearings to the inner race of the bearings on the chain sprocket shaft journal,
and then put them into the outer race of the bearings on the side plates.
5. While assembling the brake mechanism, care should be taken on mesh the slanting teeth of the ratchet disc and
the pawl. Make sure that the pawl is controlled by the spring sensitively and reliably. Then turn the hand wheel
clockwise after screwing it onto the driving shaft and it must press the disc and the plates on the brake seat. Turning
it counterclockwise, there should be clearances between the disc and the plates.
6. The stay and the right side plate are in transition f t. Care should be taken not to dismantle them.
7. After cleaning and repair, the chain block should be subjected to no-load and heavy load tests. If it works normally
put it into operation.
8. Keep clean the friction surfaces of the brake mechanism while lubricating or operating the chain block. Inspect the
brake mechanism frequently so as to avoid faulty braking or falling of load.
9. For convenience of maintenance and dismantling, one of the links of the hand chain is open.
