Extension Cord

Make sure your extension cord is in good condition. When using an
extension cord be sure it is heavy enough to carry the current your
product will draw. An undersized extension 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 gauge.
The smaller the gauge number, the heavier the cord.

Double Insulation

Double insulated tools are constructed throughout with two
separate layers of electrical insulation or one double thickness
of insulation between you and the toolʼs electrical system.
Tools built with this insulation system are not intended to be
grounded. As a result, your tool is equipped with a two prong
plug which permits you to use extension cords without concern
for maintaining a ground connection. NOTE: Double insulation does
not take the place of normal safety precautions when operating this
tool. The insulation system is for added protection against injury
resulting from a possible electrical insulation failure within the tool.
REPLACEMENT PARTS: When servicing all tools, USE IDENTICAL
REPLACEMENT PARTS. Repair or replace damaged cords.
