
Grasp and hold the collar of the chuck with one hand. With
your other hand, rotate the chuck sleeve to close and tighten
the chuck jaws.
WARNING:
Do not hold the chuck sleeve with one hand and use the
power of the drill to tighten the chuck jaws on the drill bit.
The chuck sleeve could slip in your hand, or your hand could
slip and come in contact with the rotating drill bit. This could
cause an accident resulting in serious personal injury.

To remove bits, lock the switch trigger and open the chuck
jaws.

The bit provided with the drill can be placed in the storage
area, located on the base of the drill.
ADJUSTING TORQUE
See Figure 7, page 9.
Rotate the torque 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 For driving screws in hard wood
• 17 - 20 For driving large screws
• 21 -
For heavy drilling
DRILLING/DRIVING SCREWS
See Figure 8, page 9.

Check the direction of rotation selector for the correct setting
(forward or reverse).

Secure the workpiece in a vise or with clamps to keep it from
turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be drilled,
or where the screw is to be driven.
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
could be present, always hold tool by insulated gripping
surfaces (handle) when performing the operation to prevent
a shock to the operator.
OPERATION
 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 breakthrough.
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 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 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.
