OPERATION
BIT BINDING
See Figure 8, page 10.
If the bit binds, the drill will suddenly react in the opposite
direction of the rotation of the bit.
To reduce the chances of bit binding:
 Always use sharp bits.
 Use the proper bit for the application.
 Drill at the correct speed for the size bit you are using.
 Avoid drilling in warped, wet or knotty material.
 Avoid drilling in workpieces that could contain hidden
fasteners or other foreign objects.
WARNING:
This tool delivers high rotational forces. Always use
the auxiliary handle when using this tool to help
resist torque reactions. Never use your body to
brace the drill. Never put your hands or other body
parts between the part of the drill being braced and
the object it is being braced against. Doing so can
result in serious personal injury.
DRILLING/DRIVING SCREWS
See Figures 9 - 11, pages 10 - 11.
 Install the auxiliary handle.
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 per-
sonal injury.
 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:
To avoid loss of control or serious personal injury,
always use both hands when operating this tool.
Grip the auxiliary handle firmly with one hand and
grip the power base with the other hand.
WARNING:
Do not drill or 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 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.
NOTE: When drilling in forward, the bit will rotate in a
clockwise direction. If the bit binds in the hole, the bit will
come to a sudden stop and the drill will suddenly react
in a counterclockwise direction.
When drilling in reverse, the bit will rotate in a counter-
clockwise direction. If the bit binds in the hole, the bit will
come to a sudden stop and the drill will suddenly react
in a clockwise direction.
 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.
