OPERATION
WARNING
To reduce the risk of injury, wear
safety goggles or glasses with side
shields. Always remove battery
pack before changing accessories
or making adjustments.
Selecting Action
MILWAUKEE Rotary Hammers have three
settings: drill only, rotary hammer, and ham-
mer only.
Fig. 3
1.
For drilling, turn the selector lever so the
arrow on the lever points to the twist drill
symbol
.
2.
For rotary hammering, turn the selector
lever so the arrow points to the hammer
and twist drill symbol
.
3.
For hammering only, turn the selector
lever so the arrow points to the hammer
symbol
.
4.
To freely rotate the bit to the desired
angle for chiseling only, turn the selector
lever so the arrow points to the symbol
O
. Then, follow step 3.
NOTE: To engage the hammering mecha-
nism, maintain pressure on the bit. When
pressure on the bit is released, the hammer-
ing action will stop.
Using the Control Switch
The control switch may be set to three
positions: forward, reverse and lock. Due
to a lockout mechanism, 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 in the
control switch from the left side of the tool.
Check the direction of rotation before use.
For reverse (counterclockwise) rotation,
push in the control switch from the right
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 mainte-
nance, changing accessories, storing the tool
and any time the tool is not in 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.
Operating
Position the tool, grasp the handles fi rmly
and pull the trigger. Always hold the tool se-
curely 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 Core Bits
Core bits are useful for drilling large holes for
conduit and pipe. MILWAUKEE Heavy-Duty
Thin Wall Core Bits have heat treated steel
bodies with durable carbide tips. They are
specially designed for fast, accurate drill-
ing with combined hammering and rotary
action.

1.
Clean and lubricate the threads on the
adapter and core bit as indicated (Fig. 4)
to make later removal easier. Screw the
threaded end of the adapter into the rear
of the core bit.
2.
Push the guide plate onto the pointed
end of the center pin. Insert the center
pin with guide plate a ssembly into to the
core bit. Be sure the small end of the
center pin is securely placed into the
hole in the center of the adapter.
3.
Insert the adapter into the bit holder of
the tool as described in "Inserting Drill
Bit or Chisel". Set the rotary hammer/drill
lever to rotary hammer.
4.
Press the center pin fi rmly against your
center mark, hold the tool fi rmly and pull
the trigger.
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.
After you have fi nished drilling the hole,
hold the tool upwards, pointing it away
from your body, and run it briefly in
forward to loosen the core bit from the
adapter.
MILWAUKEE Heavy-Duty Thin Wall Core
Bits drill holes up to 3" deep. To make deeper
holes, remove the bit, break and remove the
core. Resume drilling.
