TOur
Drill
IS
DOUBLE-INSULATED to give you
added safety. This weans
that it Is 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 Drill is equipped with a two-pronged plug
which permits
you to use any conventional 120 volt electrical outlet
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 Double-Insulated
Tools,
use ONLY IDENTICAL REPLACEMENT PARTS. Replace or repair damaged
cords.
EXTENSION
CORD
When using this drill at a considerable distance from power source, an
extension cord of adequate size must be used for safety, and to prevent
loss of power and over-heating. For a 120-volt tool, the minimum size of
the wires in any extension cord up to 75 feet long must be 18-gauge
(American Wire Gauge). From 75 to 100 feet, 16-gauge wire is required
throughout the extension. 220-volt tools require a minimum wire size of
only 18-gauge in extension cord lengths up to 100 feet long. (NOTE:
16-gauge wire is heavier than 18-gauge wire and will carry current for
longer distances without a voltage drop.)
Before using pension Cords, inspect them for loose or exposed wires
and damaged insulation. Make any needed repairs or replacement before
using your power tool.
