SPECIFIC SAFETY RULES
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact acci-
dentally occurs, fl ush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
• Hold power tools by insulated gripping sur-
faces, when performing an operation where the
cutting tool may contact hidden wiring or its
own cord. Cutting accessory contacting a "live" wire
may make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
• Keep hands away from all cutting edges and
moving parts.
• Maintain labels and nameplates. These carry im-
portant information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
• WARNING Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to fi lter out microscopic particles.

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 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
chisels.
Selecting Action
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.
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
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
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.
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.
WARNING Always remove battery
pack before changing or removing ac-
cessories. Only use accessories specifi cally
recommended for this tool. Others may be
hazardous.
ASSEMBLY
WARNING Recharge only with the
charger specifi ed for the battery. For spe-
cifi c charging instructions, read the operator’s
manual supplied with your charger and battery.
Removing Battery Pack from Tool

pack away from the tool.
Inserting Battery Pack into Tool
To insert the battery pack onto the tool, slide the

securely into place.
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 depth gauge rod.
3. Release the clamping lever.
WARNING Always remove battery
pack before changing or removing ac-
cessories. Only use accessories specifi cally
recommended for this tool. Others may be
hazardous.
