Boom Support

NEVER PERFORM WORK UNDER THE BOOM ASSEMBLY WITH THE
PLATFORM ELEVATED WITHOUT FIRST SUPPORTING THE BOOM
ASSEMBLY��

DO NOT work beneath the boom assembly with the platform elevated unless the boom assembly is
properly supported.

Use a sling and overhead hoist rated for 3 tons (2,700 kg) or more.

Wrap a sling under the outer end of the boom as shown below. Connect it to the overhead hoist, then
lift enough that the weight of the boom assembly is being supported by the hoist.
