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 depth gauge rod.
3. Release the clamping lever.

Installing Drill Bits and Chisels
NOTE: Only use accessories with SDS or SDS Plus
shanks.
Be sure that the shank of the bit is clean. Dirt particles
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 motor overload-
ing 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
chisels.
OPERATION
Always remove battery pack before
WARNING
changing or removing accesso-
ries. Only use accessories specifically recom-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, keep hands away
from the bit and all moving parts. Always wear
safety goggles or glasses with side shields.
To reduce the risk of injury, wear a dust mask or
use an OSHA compliant dust extraction solution
when working in dusty situations.
To reduce the risk of injury, always use a side
handle when using this tool. Always brace or
hold securely.
Selecting Action
MILWAUKEE Rotary Hammers have three settings:
rotation only, rotary hammer, and hammer only.
Always allow the motor to come to a complete stop
before changing the mode selection to avoid dam-
age to the tool.
1. For rotation only, 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 button
and turn the selector lever so
the arrow points to the hammer and twist drill
symbol.
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 ham-
mering only, press in the selector release button
and turn the selector lever to the
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
The control switch may be set to three positions:
forward, reverse and lock. Always allow the motor
to come to a complete stop before using the control
switch to avoid damage to the tool.
For forward (clockwise) rotation, push in the control
switch from the right side of the tool. Check the direc-
tion 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.
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 maintenance, 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 firmly and pull
the trigger.
2. To vary the speed, increase or decrease the pres-
sure 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.
Position the tool, grasp the handles firmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been de-
signed to achieve top performance with only moder-
ate 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 flutes 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.
Applying greater pressure does not
WARNING
increase the tool's effectiveness.
If the applied working pressure is too high, the
shock absorber will be pushed together making
the vibrations to the handle noticeably stronger.
Operator Force
The Anti-Vibration System provides the operator with
comfort without sacrificing power or performance.
Ideal operator force compresses the bellows slightly
and allows the tool to work aggressively while the
handle remains steady.
Excessive force compresses the bellows significantly
and reduces vibration dampening. Users will be able
to feel the difference and should adjust the force to
the handle accordingly.
