OPERATION
If the bit jams in the workpiece or if the drill stalls,
stop the tool immediately. Remove the bit from the
workpiece and determine the reason for jamming.
NOTE: This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the brake
is functioning properly, sparks will be visible through the
vent slots on the housing. This is normal and is the action
of the brake.
WOOD DRILLING
For maximum performance, use high speed steel bits for
wooddrilling.
Begin drilling at a very low speed to prevent the bit
from slipping off the starting point. Increase the speed

When drilling through holes, place a block of wood
behind the workpiece to prevent ragged or splintered
edgesonthebacksideofthehole.
For maximum performance, use high speed steel bits for
metal or steel drilling.
Begin drilling at a very low speed to prevent the bit
fromslippingoffthestartingpoint.
Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pres-
sure will:
•Overheatthedrill;
•Wearthebearings;
•Bendorburnbits;and
•Produceoff-centerorirregular-shapedholes.
When drilling large holes in metal, start with a small bit,
then finish with a larger bit. Also, lubricate the bit with
oil to improve drilling action and increase bit life.
