To reduce the risk of elec-
tric shock, check work area for hidden pipes
and wires before drilling or driving screws.

NOTE:
Use a piece of scrap material to test the
different clutch positions before driving screws into
the workpiece.
Using Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not depressed. Always allow
the motor to come to a complete stop before using
the control switch.
To
lock
the trigger,
push the control switch to the
center position. The trigger will not work while
the control switch is in the center locked position.
Always lock the trigger or remove the battery
pack before performing maintenance, changing
accessories, storing the tool and any time the tool
is not in use.
Starting, Stopping and Controlling Speed
1. To
start
the tool, grasp the handle fi rmly and pull
the trigger.
2. To
vary
the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To
stop
the tool, release the trigger. Make sure
the bit comes to a complete stop before laying
the tool down.
Electric Brake
The electric brake engages when the trigger is
released, causing the bit to stop and allowing you
to proceed with your work. Generally, the bit stops
within two seconds. However, there may be a delay
between the time you release the trigger and when
the brake engages. Occasionally the brake may
miss completely. If the brake misses frequently, the
tool needs servicing by an authorized
MILWAUKEE
service facility.
Drilling
Set both the hammer/drill and torque selector col-
lars to the drill positions.
Place the bit on the work surface and apply fi rm
pressure before starting. Too much pressure will
slow the bit and reduce drilling effi ciency. Too little
pressure will cause the bit to slide over the work
area and dull the point of the bit.
If the tool begins to stall, reduce pressure slightly to
allow the bit to regain speed. If the bit binds, reverse
the motor to free the bit from the workpiece.
Bit Binding
A high rotational force occurs when a bit binds. If
the bit binds, the tool will be forced in the opposite
direction of the bit rotation. Bits may bind if they
are misaligned or when they are breaking through
a hole. Wood boring bits can also bind if they run
into nails or knots. Be prepared for bit binding
situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are bits that
are designed for specifi c purposes.
• Use caution when drilling pitchy, knotty, wet or
warped material or when drilling in material that
may contain nails.

Drilling in Masonry
When drilling in masonry, select the hammer-drill
operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder
block requires little pressure. Hard materials like
concrete require more pressure. A smooth, even
fl ow of dust indicates the proper drilling rate. Do not
let the bit spin in the hole without cutting. Do not
use water to settle dust or to cool bit. Both actions
will damage the carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or
hard materials. Set the torque selector collar to the
proper position and set the speed to low. Use the
proper style and size screwdriver bit for the type
of screw you are using.
With the screwdriver bit in the screw, place the tip of
the screw on the workpiece and apply fi rm pressure
before pulling the trigger. Screws can be removed
by reversing the motor.
Overloading
Continuous overloading may cause permanent
damage to tool or battery pack.
WARNING
High rotational force. To
reduce the risk of injury, always hold or brace
securely. Always use side handle on tools.
For
forward
(clockwise) rotation, push in the control
switch from the right side of the tool.
Check the
direction of rotation before use.
For
reverse
(counterclockwise) rotation, push in the
control switch from the left side of the tool.
Check
direction of rotation before use.
Drilling in Wood, Composition Materials and
Plastic
When drilling in wood, composition materials and
plastic, start the drill slowly, gradually increasing
speed as you drill. When drilling into wood, use
wood augers or twist drill bits. Always use sharp
bits. When using twist drill bits, pull the bit out of the
hole frequently to clear chips from the bit fl utes. To
reduce the chance of splintering, back work with a
piece of scrap wood. Select low speeds for plastics
with a low melting point.
Drilling in Metal
When drilling in metal, use high speed steel twist
drills or hole saws. Use a center punch to start the
hole. Lubricate drill bits with cutting oil when drilling
in iron or steel. Use a coolant when drilling in non-
ferrous metals such as copper, brass or aluminum.
Back the material to prevent binding and distortion
on breakthrough.
