SPEED INCREASER REPAIR (CONT).
Injury to personnel or damage to equipment could occur from improper
hoisting. Hoist the load slowly to avoid tearing out lifting bail assembly,
slipping slings, or load shift. Do not jerk the load or swing it from side-to-
side when hoisting. This places additional stress on hoisting components
which can cause failure and loss of load. Be sure hoisting equipment is
on solid footing and is suitable for the size of the load. Watch boom angle
and overhead clearance when hoisting.
