Craftsman 315.DD2010 User Manual

10 - English
 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
wooddrilling.
 Begin drilling at a very low speed to prevent the bit
from slipping off the starting point. Increase the speed
asthedrillbitbitesintothematerial.
 When drilling through holes, place a block of wood
behind the workpiece to prevent ragged or splintered
edgesonthebacksideofthehole.
METAL DRILLING
For maximum performance, use high speed steel bits for
metal or steel drilling.
 Begin drilling at a very low speed to prevent the bit
fromslippingoffthestartingpoint.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much
pressure will:
 •Overheatthedrill;
 •Wearthebearings;
OPERATION
 •Bendorburnbits;and
 •Produceoff-centerorirregular-shapedholes.
 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.
DRIVING SCREWS
 Check the direction of rotation selector for the correct
setting(forwardorreverse).
 Secure the material to be driven in a vise or with
clamps to keep it from turning as the screwdriver bit
rotates.
 Hold the drill firmly. Place the bit on the screw head and
slowly depress the switch trigger. Start the bit slowly for
more control.
 Move the screwdriver bit toward the workpiece. Do not
force the drill. Let the tool do the work.
WARNING: Do not drive a screw where there is
likely to be hidden wiring behind the surface. Con-
tact with a “live” wire will make exposed metal parts
of the tool “live” and possibly shock the operator.
If you must drive a screw where hidden wire may
be present, always hold tool by insulated gripping
surfaces (handle) when performing the operation to
prevent a shock to the operator.
