dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.

19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENTPARTS. When servicing, useonly identicalreplacementparts.
21. POLARIZED PLUGS: To reducethe risk of electric shock, this equipment has a
polarizedplug (one blade is wider than the other). This plugwill fit ina polarized
outlet onlyone way. Ifthe plugdoes notfit fully inthe outlet, reversethe plug.
If it
still
does not fit, contact a qualifiedelectrician to installthe proper outlet. Do not
changethe pluginany way.
VOLTAGE WARNING: Before connectingthe tooltoa powersource (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source withvoltage greater than that specified
for the tool can result in SERIOUS INJURY to the user
- as well as damage to
the tool. If in doubt,
DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

Drillingoperation
Drilling in wood
When drilling in wood, best results are obtainedwith wood drills equipped with a guide
screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
To preventthe bitfrom slippingwhen starting
a hole, make an indentation with a center-
punch and hammer
at the point to be drilled. Place the point of the bit inthe indenta-
tion and startdrilling.
Use
a cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
0 Drillinginmetal
CAUTION
:
*Pressing excessively on the tool will not speed up the drilling. Infact, this excessive
pressure will only serve to damage the tip of your bit, decrease the tool performance
and shortenthe service lifeof the tool.
*There
is a tremendous force exerted on the tool/bit at the time of holebreak through.
Hold the tool firmly and exert care when the bit begins to break through the workpiece.
*Always grip the smallworkpiecefirmly with
a vise or a holding means.
*A stuck bit can be removed simply by setting the reversing switch to reverse rotation
in order to back out. However, the tool will pull away easily unless you hold
it firmly
beforestarting the tool.
