3-prong grounding-type plugs and 3-pole receptacles that accept
the tool's plug. Replace or repair damaged cords. Make sure your
extension cord is in good condition. When using an extension cord,
be sure to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. The following table
shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord.

parts, breakage of parts, mounting, and any other conditions that
may affect its operation. A guard or other part that is damaged
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service
