WARNINGOPERATION
To reduce the risk of injury, wear
safety goggles or glasses with side
shields.
Selecting Speed
The speed selector is on top of the motor
housing. Allow the tool to come to a complete
stop before changing speeds. See “Ap-
plications” for recommended speeds under
various conditions.
1. For Low speed (up to 600 RPM), push
the speed selector to the left.
2. For High speed (up to 1800 RPM), push
the speed selector to the right.
Using Keyless Chucks
Your cordless tool is equipped with a spindle
lock. The chuck can be tightened with one
hand, creating higher grip strengths on the
bit.
Always remove the battery pack or lock the
trigger before inserting or removing bits.
1. To open the chuck jaws, turn the sleeve
in the counterclockwise direction.
When using drill bits, allow the bit to
strike the bottom of the chuck. Center
the bit in the chuck jaws and lift it about
1/16" off of the bottom.
When using screwdriver bits, insert the
bit far enough for the chuck jaws to grip
the hex of the bit.
2. To close the chuck jaws, turn the sleeve
in the clockwise direction. The bit is se-
cure when the chuck makes a ratcheting
sound and the sleeve can not be rotated
any further.
3. To remove the bit, turn the sleeve in the
counterclockwise direction.
NOTE: A ratcheting sound may be heard
when the chuck is opened or closed. This
noise is part of the locking feature, and
does not indicate a problem with the chuck's
operation.

2. To use the drilling only mode (Fig. 7),
rotate the hammer/drill selector collar
until the drill symbol appears in line
with the arrow. Then rotate the Torque
selector collar until the drill symbol
appears in line with the arrow.
The adjustable clutch ,when properly ad-
justed, will slip at a preset torque to prevent
driving the screw too deep into different
materials and to prevent damage to the
screw or tool.
The torque specifi cations shown here are
approximate values.
NOTE: Use a piece of scrap material to test
the different clutch positions before driving
screws into the workpiece.

Selecting Hammer or Drill Action
MILWAUKEE Hammer-Drills are designed
for three operating modes: drilling with
hammering action, drilling only, and driving
screws. To set the operating mode, rotate
the hammer/drill selector collar and torque
selector collar to the desired symbols.
1. To use the hammer-drilling mode
(Fig. 6), rotate the hammer/drill selector
collar until the hammer symbol ap-
pears in line with the arrow. Then rotate
the Torque selector collar until the drill
symbol appears in line with the ar-
row. Apply pressure to the bit to engage
the hammering mechanism.
For reverse (counterclockwise) rotation,
push in the control switch from the left side
of the tool (Fig. 10). Check direction of
rotation before use.
Using Control Switch
The control switch may be set to three posi-
tions: forward, reverse and lock. Due to a
lockout mechanism, 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.
For forward (clockwise) rotation, push in the
control switch from the right side of the tool
(Fig. 9). Check the direction of rotation
before use.

To lock the trigger, push the control switch
to the center position (Fig. 11). 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.

NOTE: When using carbide bits, do not use
water to settle dust. Do not attempt to drill
through steel reinforcing rods. This will dam-
age the carbide bits.
3. To use the driving screws mode
(Fig. 8), rotate the hammer/drill selector
collar until the drill symbol appears
in line with the arrow. Then rotate the
torque selector collar until the desired
clutch setting appears in line with the
arrow.
