ASSEMBLY
Inserting/Removing Battery Pack
Insert the battery pack from the front by sliding
battery pack into the body of the tool. Insert the
battery pack until the battery latches lock.
To remove the battery pack, press in both battery
latches and slide the battery pack off of the tool.
WARNING Recharge only with the
charger specifi ed for the battery. For specifi c
charging instructions, read the operator’s
manual supplied with your charger and
battery.
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.

proximate values.

NOTE: The number selected on the torque collar
has no effect on operation of the drill in hammer
mode.
NOTE: When using carbide bits, do not use wa-
ter 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 ap-
plication 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.
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.
Installing the Side Handle
1. To install the side handle,
loosen the side handle
grip until the hooks are
far enough apart to fi t into
the slots on the gear case
ring. Position the side
handle on the top, left,
or right side of the tool.
Tighten the side handle grip until it is secure.
2. To remove the side handle, loosen the side
handle grip until the side handle can be removed.
Reposition and tighten securely.
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely. Ensure side
handle is tightened securely before each use.
Using Keyless Chucks
This 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 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 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 coun-
terclockwise 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
The speed selector is on top of the motor housing.
Allow the tool to come to a complete stop before
changing speeds. See “Applications” for recom-
mended speeds under various conditions.
1. For Low speed (up to 450 RPM), push the speed
selector to display “1”.
2. For High speed (up to 1800 RPM), push the
speed selector to display “2”.
Selecting Hammer, Drill or Drive Action
MILWAUKEE Hammer-Drills have 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. Ap-
ply pressure to the bit to engage the hammering
mechanism.
NOTE: Because the above settings are only a
guide, use a piece of scrap material to test the dif-
ferent 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 pressed. 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. 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.

Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle fi rmly and pull
the trigger.
NOTE: An LED is turned on when the trigger is
pulled.
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.
Drilling
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.
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely. Ensure side
handle is tightened securely before each use.
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
