LIFTING CAPACITY AFFECTED BY PEEL AND THICKNESS. SEE 1

4 OF THE "IMPORTANT FACTS" (PAGE 8

9) IN THIS INSTRUCTION MANUAL.

t SEE SECTION 6 OF THE "IMPORTANT FACTS" (PAGE 9) IN THIS INSTRUCT/ON MANUAL. ALSO, READ RECOMMENDED LIFTING PROCEDURES (PAGE 12).

Values shown are maximum rated capacities when all operating instructions and warnings are strictly followed. Values based on SAE 1020.

Higher alloy steels and other magnetic materials will require further reductions of these rated capacities.

(See Guidelines for the Reduction of Rated Lifting Capacity.)
