Bracing for reverse rotation
When drilling in reverse, the bit will rotate in a coun-
terclockwise 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.
The following fi gures show examples of properly
bracing the tool for reverse rotation.
A. Reverse (counterclockwise) rotation
B. Reaction
C. Brace drill with motor motor housing here
D. Brace drill with side handle here
If the bit binds, the motor housing braced against
the stud will hold the drill in position.

Shifting Speeds
WARNING
To reduce the risk of injury
and damage to the tool, shift speeds only
when the drill is at a stop.
Use the shift knob to select High or Low speed.
High speed (950 RPM) is the low torque setting.
Low speed (350 RPM) is the high torque setting.
See the "Specifi cations" section for bit capacity
limits under high and low speeds.
Always turn off the switch and shift speeds while
the tool is stopped. Never shift the drill while it is
moving or when it is under load.
Reversing
A reversing switch is located opposite the trigger
A
switch for removal of bits from holes. Permit the
motor to come to a complete stop before reversing.
Reversing the tool with the gears in motion may
cause severe damage. When removing selfeed bits
from partially drilled holes, fl ick the trigger switch
when the tool is in reverse to free the threaded pilot
screw. When the threads are loose, lift the bit from
the workpiece with the motor stopped.
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 trigger is not pulled. Always allow the motor to
come to a complete stop before using the control
switch.
For Forward (clockwise) rotation, push the control
switch from the right side of the tool. Check the
direction of rotation before use.
For Reverse (counterclockwise) rotation, push the
control switch from the left side of the tool. Check
direction of rotation before use.
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 acces-
sories, storing the tool and any time the tool is not
in use.

WARNING
To reduce the risk of injury,
keep hands away from the bit and all moving
parts.
Starting, Stopping and Controlling Speed
These tools may be operated at any speed from
0 to full speed.
1. To start the tool, pull the trigger.
NOTE: An LED is turned on when the trigger is
pulled.
2. To vary the driving speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed.
3. To stop the tool, release the trigger.
WARNING
To reduce the risk of explo-
sion, electric shock and property damage,
always check the work area for hidden pipes
and wires before drilling.
Drilling
1. Before drilling, be sure the workpiece is clamped
securely. A poorly secured piece of material may
result in personal injury or inaccurate drilling.
Use backing material to prevent damage to the
workpiece during breakthrough. When drilling in
light gauge metal or wood, use a wooden block
to back up the material to prevent damage to the
workpiece.
2. When starting a hole, place the drill bit on the
work surface and apply fi rm pressure.
To start a selfeed bit, run the threaded feed
screw into the work by fl icking the trigger switch,
permitting the bit to coast until the teeth contact
the work surface. Align the bit properly before
proceeding. This will reduce cocking and jam-
ming when starting.
When drilling in metal, mark the center of the hole
to be drilled with a center punch to give the bit a
start and to prevent it from "walking." Lubricate
the drill bit with cutting oil when drilling iron or
steel. Use a coolant when drilling nonferrous
metals such as copper, brass or aluminum.
3. Always apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to cause the bit to bind.
When using twist drill bits, pull the bit out fre-
quently to clear chips from the fl utes.
When using selfeed bits, if the clutch slips, pull
the bit up very slightly and then push it toward
the workpiece. Repeat this several times.
4. Reduce pressure and ease the bit through the
last part of the hole. While the tool is still running,
pull the bit out of the hole to prevent jamming.
When using selfeed bits, decrease the drilling
pressure when the feed screw point breaks
through the workpiece. Proceed with steady,
even pressure.
MAINTENANCE
WARNING
To reduce the risk of injury,
always unplug the charger and remove
the battery pack from the charger or tool before
performing any maintenance. Never disassem-
ble the tool, battery pack or charger. Contact
a MILWAUKEE service facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
After six months to one year, depending on use,
return the tool, battery pack and charger to a
MILWAUKEE service facility for:
• Lubrication
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (battery pack, charger, motor)
• Testing to assure proper mechanical and electrical
operation
If the tool does not start or operate at full power
with a fully charged battery pack, clean the contacts
on the battery pack. If the tool still does not work
properly, return the tool, charger and battery pack,
to a MILWAUKEE service facility for repairs.
WARNING
To reduce the risk of personal
injury and damage, never immerse your
tool, battery pack or charger in liquid or allow
a liquid to fl ow inside them.
Cleaning
Clean dust and debris from charger and tool vents.
Keep tool handles clean, dry and free of oil or
grease. Use only mild soap and a damp cloth to
clean the tool, battery pack and charger since certain
cleaning agents and solvents are harmful to plastics
and other insulated parts. Some of these include
gasoline, turpentine, lacquer thinner, paint thinner,
chlorinated cleaning solvents, ammonia and house-
hold detergents containing ammonia. Never use
fl ammable or combustible solvents around tools.
Repairs
For repairs, return the tool, battery pack and char-
ger to the nearest service center.
ACCESSORIES
WARNING
Always remove battery
pack before changing or removing ac-
cessories. Only use accessories specifi cally
recommended for this tool. Others may be
hazardous.
For a complete listing of accessories refer to your
MILWAUKEE Electric Tool catalog or go online
to www.milwaukeetool.com. To obtain a catalog,
contact your local distributor or service center.
