Drilling/Driving Screws
A level is located on the top of the motor housing to help keep
the drill bit level during use (Fig. 18).
1. Check the direction of rotation selector for the correct
setting (forward or reverse).
2.
Select low speed (1) or high speed (2), depending on your
application. Refer to Speed Settings and Adjusting Torque.
3. Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
4.
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 may be present, always hold tool by insulated gripping
surfaces (handle) when performing the operation to prevent a
shock to the operator.
5.
Depress the switch trigger to start the drill.
6.
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.
m
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.
7.
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.
8.
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 + 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
1. Increase the speed as the drill bit bites into the material.
2.
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
1. 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.
2.
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.
3.
When drilling large holes in metal, start with a small bit,
then finish with a larger bit.

WARNING!
When servicing, use only identical
replacement parts. Use of any other part could create a hazard
or cause product damage.
m
WARNING!
To avoid accidents, always diconnect the
tool and/or charger from the power supply before cleaning.
Ventilation openings and trigger switch must be kept clean
and free of foreign matter. Do not attempt to clean by inserting
pointed objects through opening.
