OPERATION
 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, be prepared for binding at bit break-
through. When these situations occur, drill has a
tendency to grab and kick opposite to the direction
of rotation and could cause loss of control when
breaking through material. If not prepared, this
loss of control can result in possible serious injury.
 With 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.

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.
Wood Drilling
 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 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.
