WARNING
To reduce the risk of injury,
always use a side handle when using
this tool. Always brace or hold securely.
Adjusting the Side Handle Position
1. Loosen the side handle by unscrewing the side
handle grip until the side handle rotates freely.
2. Rotate the side handle to the desired position.
3. Tighten the side handle grip securely.
Setting the Depth Gauge
1. Press in the clamping lever.
2. Slide the depth gauge rod backward or forward
until it is set for the desired depth.
NOTE: The drilling depth is the distance between
the tip of the bit and the tip of the rod.
3. Release the clamping lever.
WARNING
To reduce the risk of injury
do not grasp the bit while the chuck is
rotating or while the bit is falling from the
chuck.
WARNING
To reduce the risk of injury,
always unplug tool before attaching
or removing accessories or making adjust-
ments. Use only specifi cally recommended
accessories. Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
WARNING
To reduce the risk of injury,
keep hands and cord away from the bit
and all moving parts.
Selecting Action
These MILWAUKEE Rotary Hammers have
three settings: drill only, rotary hammer, and
hammer only. Always allow the motor to
come to a complete stop before changing the
mode selection to avoid damage to the tool.
1. For drilling, press in the
selector release button and
turn the selector lever so the
arrow on the lever points to
the twist drill symbol.
2. For rotary hammering, press
in the selector release but-
ton and turn the selector
lever so the arrow points to the hammer and
twist drill symbol.
ASSEMBLY
Installing Drill Bits and Chisels
Only use accessories with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt par-
ticles may cause the bit to line up improperly. Do not
use bits larger than the maximum recommended
capacity of the drill because gear damage or mo-
tor overloading may result. For best performance,
be sure that the bit is properly sharpened and the
shank is lightly greased before use.
1. Insert the bit or chisel into the nose of the tool.
2. Rotate bit slowly until it aligns with the locking
mechanism.
3. Push bit into tool until it locks.
4. Check that the bit is locked properly; it should
be possible to pull the bit back and forth slightly
(about 1/4").
5. To remove bits and chisels,
pull bit holder release collar
toward the rear of tool and
remove bit.
NOTE: Use caution when
handling hot bits and chis-
els.
OPERATION
3. For hammering only, press in the selector release
button and turn the selector lever so the arrow
points to the hammer symbol.
4. To freely rotate the bit to the desired angle for
hammering only, press in the selector release
button and turn the selector lever to the
symbol. Then, follow step 3.
NOTE: To engage the hammering mechanism,
maintain pressure on the bit. When pressure on the
bit is released, the hammering action will stop.
Using the Control Switch
Always allow the motor to
come to a complete stop be-
fore using the control switch.
For forward (clockwise) rota-
tion, push the control switch
to the left side of the tool.
Check the direction of rotation
before use.
For reverse (counterclock-
wise) rotation, push the con-
trol switch to the right 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.
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 tool comes to a complete stop before laying
the tool down.
Lock-On
The lock-on button holds the trigger in the ON posi-
tion for continuous full speed use.
1. To lock the trigger, hold in the lock button while
pulling the trigger. Release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock button will pop out.
Operating
Position the tool, grasp the handles fi rmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been
designed to achieve top performance with only
moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling large
or deep holes, pull the bit partially out of the hole
while the tool is running to help clear dust. Do not
use water to settle the dust since it will clog the bit
fl utes and tend to make the bit bind in the hole. If
the bit should bind, a built-in, non-adjustable slip
clutch prevents the bit from turning. If this occurs,
stop the tool, free the bit and begin again.

Using Rotary Percussion Core Bits
Core bits are useful for drilling larger holes for
conduit and pipe. MILWAUKEE Thin Wall Core
Bits have heat-treated steel bodies with durable
carbide tips. These core bits are specially designed
for fast, accurate drilling with combined hammering
and rotary action.
1. Clean and lubricate the threads
on the adapter and core bit to
make later removal easier. Screw
the threaded end of the adapter
into the rear of the core bit.
Adapter
NOTE: For core bits 1- 1/4"
and larger, push the guide
plate onto the pointed end of
the center pin. Insert the center

pin and guide plate assembly
and
into the core bit. Be sure the
lubricate
small end of the center pin is threads
securely placed into the hole

2. Insert the adapter into the nose
of the tool as described in "In-
stalling Bits". Set the hammer/
drill shift knob to hammering
with rotation.

3. Press the center pin firmly
Pin
against your center mark, hold
the tool fi rmly and pull the trigger.
NOTE: If a center pin and guide

template or notched board to
start the hole.
5. After drilling to about the depth of the core bit
teeth, remove the center pin and guide plate from
the core bit. Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briefl y
in forward to loosen the core bit from the adapter.
NOTE: To make holes deeper than 3", remove the
core bit, break and remove the core. Resume drilling.
