Use and Care Manual

OPERATION
 When drilling hard, smooth surfaces, use a center punch
to mark the desired hole location. This will prevent the bit
from slipping off-center as the hole is started.
 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 trig-
ger 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 AND METAL DRILLING
For maximum performance, use high speed steel bits for
woodormetaldrilling.Selectdrillingmode.Begindrilling
at a very low speed to prevent the bit from slipping off the
starting point.

 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 and Steel Drilling
 Use a light oil on the drill bit to keep it from overheating.
The oil will prolong the life of the bit and increase the
drilling action.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• 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.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits or designated hammer drill bits when drilling
holes in brick, tile, concrete, etc. Select hammer mode.
 Apply light pressure at medium speed for best results in
brick.
 Apply additional pressure for hard materials such as
concrete.
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
startingpoint.
MAINTENANCE
WARNING:
When servicing, use only identical replacement
parts. Use of any other parts could create a hazard
or cause product damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
