OPERATION
SELECTING DRILL, DRIVE, OR HAMMER
MODE
See Figure 11, page 13.
Drill mode should be used for drilling and other heavy duty
applications. Drive mode should be used for driving screws.
Hammer mode should be used for hammer drilling.
Select the option that best matches the type of bit, fastener,
and material you will be using.
 Choose your application.
 Choose the correct speed: LO (1) or HI (2).
 Choose the correct mode: drill, drive or hammer.
NOTE: The hammer drill has not been designed for reverse
hammering.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, concrete, etc.
Use carbide-tipped bits and select drill mode when drilling
in materials with hard, brittle surfaces such as tile, etc.
Use twist drills, hole saws, etc. and drill mode when drilling
in soft materials.
NOTE: When drilling in hammer mode, it is advisable to use
LO (1) Speed.
DRILLING/DRIVING SCREWS
See Figure 12, page 13.
WARNING:
Always use the auxiliary handle when using this
tool to help resist torque reactions. Binding or
stalling of this product could lead to serious
personal injury.
 Install the auxiliary handle.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use LO (1) speed for high torque applications and
HI (2) speed for fast drilling or driving applications. Refer
to Two-Speed Gear Train and Adjusting Torque.
 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 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
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 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.
