Important Safety Instructions

WARNING: When using electric tools, basic safety precautions
should always be followed to reduce risk of fire, electric shock, and
personal injury, including the following:

READ ALL INSTRUCTIONS

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 tool's 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.

CAUTION: WHEN SERVICING USE ONLY IDENTICAL

REPLACEMENT PARTS. Repair or replace damaged cords.

LOCKING BUTTON

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on
equipment to reduce the risk of electric shock. When provided. this
plug will fit into a polarized outlet only one way. If the plug does not
fit fully into the outlet, reverse the plug. If it still does not fit, contact
a qualified electrician to install the proper outlet. Do not change the
plug in any way.
