OPERATION
WARNING
To reduce the risk of injury, wear
safety goggles or glasses with side
shields.
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.
Fig. 1
Sleeve
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 secure 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.

Selecting Speed
Fig. 2
The speed selector is on top of the motor
housing. Allow the tool to come to a com-
plete stop before changing speeds. See
"Applications" for recommended speeds
under various conditions.
1. For Low speed (up to 450 RPM), push
the speed selector back, to display
"1".
2. For High speed (up to 1700 RPM), push
the speed selector forward, to display
"2".
Selecting Hammer, Drill or Drive 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 application selector collar and torque
selector collar to the desired symbols.
1. To use the hammer-drilling mode,
rotate the application selector collar until
the hammer symbol
appears in line
with the arrow. Apply pressure to the bit
to engage the hammering mechanism.
NOTE: The number selected on the
torque collar has no effect on operation
of the drill in hammer mode.

To Hammer
NOTE: When using carbide bits, do not
use water to settle dust. Do not attempt
to drill through steel reinforcing rods.
This will damage the carbide bits.
2. To use the drilling only mode, rotate
the application selector collar until the
drill symbol
appears in line with the
arrow.
NOTE: The number selected on the
torque collar has no effect on operation
of the drill in drilling mode.

3. To use the driving screws mode rotate
the application selector collar until the
drive symbol
appears in line with the
arrow. Then rotate the torque selector
collar until the desired clutch setting
appears in line with the arrow.

To Drive Screws
The adjustable clutch, when properly
adjusted, 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
