CHAIN

Inspect chain at least once a month. Between regular inspections, check visually daily for nicks, gouges, weld splatter,
corrosion, or distorted links. Inspect chain thoroughly if it does not feed smoothly over load sheaves. Inspect as follows:

1. Clean chain with solvent before inspection.

2. Test hoist with load and observe operation of chain over load sheaves.

3. Slacken chain and inspect contact points for excessive wear. Refer to Figure 2.

4. Using caliper-type gauge, measure inside length of 5 links under light tension.

Refer to Figure 8. Replace chain if measurement exceeds maximum allowable gauge length as above.

5. Chain oiling is not mandatory but will increase the life of the chain.
