Operation Instructions:

Review “Safety Guidelines” on p. 2-3 before using the boom.

1. Insert fork truck tines into the fork pockets and drive as far forward as possible; then lower the forks completely.

The drawings below demonstrate this step:

2. Securely connect the boom to the carriage of the fork truck with the safety chain.

Wrap the safety chain (or strap) around the fork carriage so that it cannot slide free of the carriage; then fasten

the hook to the chain/strap. There should be no slack in the chain/strap. The only purpose of the safety chain is to
prevent the boom from sliding off of the forks—it is NOT intended or designed to bear the full load rating.

3. [Telescoping models only] Adjust the boom length:

a. Loosen the X-handle locking bolt (“locking bolt”), by turning it counterclockwise.
b. Grasp the adjustment handle at the end of the boom and pull the boom to the desired length.
c. Tighten the locking bolt by turning it clockwise. Turn the locking bolt until it cannot be tightened more.
