CAUTION: Keep extension cords away from the sanding area and position the cord so that it will not get caught on lumber,
tools, etc., during sanding.
WARNING: CHECK EXTENSION CORDS BEFORE EACH USE. IF DAMAGED REPLACE IMMEDIATELY.
NEVER USE TOOL WITH A DAMAGED CORD SINCE TOUCHING THE DAMAGED AREA COULD CAUSE
ELECTRICAL SHOCK RESULTING IN SERIOUS INJURY.

to comply with AS3199, Approval and Test Specification, Cord Extension Sets. When working with your tool outdoors, use an
extension cord suitable for outdoor use and so marked.
