OPERATION
ADJUSTING TORQUE/DRIVING SCREWS
See Figures 7 - 9, page 12.
When using the drill for various driving applications, increas-
ing or decreasing the torque helps prevent the possibility of
damaging screw heads, threads, workpiece, etc. In general,
torque intensity should correspond to the screw diameter.
If the torque is too high or the screws too small, the screws
may be damaged or broken. The torque is adjusted by
rotating the torque adjustment ring.
The torque is greater when the torque adjustment ring is
set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
Rotate the adjustment ring to the proper torque setting
for the type of material and size of screw you are using.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard
materials
• 13 - 16 driving screws into hard wood
• 17 - 23 For driving large screws
• For heavy drilling
WARNING:
Do not drive a screw where there is likely to be
hidden wiring behind the surface. Contact 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.
 Depress the switch trigger to start the drill.
 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 direc-
tion 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.

 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
trigger is released, the chuck stops turning.
NOTE: If operation creates considerable dust, frequent
vacuuming of the work area is recommended.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode by rotating the
torque adjustment ring to the drill bit icon. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
 Select drill mode.
 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
 Select drill mode.
 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.
