2o IMPORTANT INFORMATION
DOUBLE INSUUTION
Yoyr 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 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 Extension Cords, inspect them for loose or exposed wires
and damaged insulation. Make any needed repairs or replacement before
using your power tool.
CHUCK
UNPLUG DRILL
Turn collar to open chuck jaws.
Insert bit into chuck as far as it
will go. Tighten chuck collar by
hand. Place chuck key in each
of the three holes, and tighten
in clockwise direction. It's im­
portant to tighten chuck with ail
three holes. To release bit, turn
chuck key counterclockwise in
just one hole, then loosen chuck
by hand.
. n \
To remove the chuck from the Drill, for
using a threaded shank accessory or
for chuck replacement, first unplug tba ^
tool. Insert the key in the chuck and "
tap it sharply in the direction the tool
normally rotates—see at right. This will
loosen the chuck shank threads and
the chuck may be unscrewed by hand.
Do not lubricate the three chuck jaws or the inside of the chuck; how­
ever, a light film of oil can be applied to the outside of the chuck to
prevent any rust from forming.
