2. IMPORTANT INFORMATION
DOUBLE INSULATION
Your Drill is DOUBLE-INSULATED to give you added safety. This means
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 improved 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 with­
out concern for maintaining a ground connection.
NOTE: DOUBLE-INSULATION does not take the place of normal safety
precautions when operating this tool. The improved 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 Extension Cords, inspect them for loose or exposed wires
and damaged insulation. Make any needed repairs or replacement before
using your power tool.
DETACHABLE CORD
T O U N L O C K
Your Drill is provided with an electric cord which attaches and detaches
easily from the tool. This feature permits storing the tool on a shelf, or on
pegboard, without wrapping the cord around the tool. It permits cord
repair or replacement without tool disassembly.
The cord fits into the bottom of the tool handle as shown in Figure 1.
Make sure that switch is “OFF” before inserting cord. Buttons must be in
the unlocked position shown in Figure 1 to allow cord to be inserted.
Pushing both buttons at the same time in the direction shown (Figure 2)
locks the cord to the handle.
B&D Extension Cords (16 Gauge, U.L. listed for indoor and outdoor use)
are available with female plug molded to fit directly into B&D tools with
detachable cord feature. They also can be used with other tools. There
are 2-wire cords for double-insulated tools and 3-wire cords for use with
both double-insulated tools and tools that require grounding.
