Chain is to be kept clean and lubricated.

Visually check chain every time hoist is used.

Hoist must not be operated when chain is twisted or kinked. An important phase of hoist maintenance is chain inspection. Check individual links and check for chain elongation.

1. Check the chain for overall wear or stretch by selecting an unworn, unstretched length of chain (at the slack end for example).; Let the chain hang vertically with a light load (about 20 pounds) on the chain to pull it taut.; Use a large caliper to measure the outside length of a convenient number of links about 12 inches).; Measure the same number of links in a used section of chain and calculate the percentage increase in length of the worn chain.

2. If the length of the worn chain is more than 1½% longer than the unused chain (0.015" per inch of chain measured), then the chain should be replaced.; If the chain is worn less than 1½%, check it at several more places along its length.

If any section is worn more than 1½%, the chain should be replaced.

The chain used on this hoist has very carefully controlled dimensions and has been heat treated. Do not attempt to substitute other manufacturer's chain.;
