Lift Chain Adjustment

1. Raise the platform to the maximum extended height and then lower it while

someone checks to see that all sheaves are turning and checks for chain damage

or wear.

2. After the platform is completely lowered, remove the plexiglass cover from the

base.

3. Chains should be tight to the touch with no loose play. Check all four lift chains

for snugness. If a chain is loose, tighten the lock nut below the clevis retainer.

Refer to Figure 3-5. Adjust any loose chain until it just becomes snug. Do not

overtighten any chain so that the platform is raised from its resting position.

4. Make sure the lock nuts are turned onto the threaded clevis ends with at least 1/8

in. of the clevis end extending through the nut. Replace any lock nut which does

not stay in position during use. Replace the plexiglass cover.
