Installing 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. Use caution
when handling hot bits and chisels.
1. Unplug tool.
2. Insert the bit or chisel into the nose of the tool.
3. Push bit into tool until it locks.
5. Check to see that the bit is locked by tugging on it.
6. To remove bits and chisels, pull back on the bit
release collar and remove bit.
WARNING To reduce the risk of injury,
always unplug tool before changing or re-
moving accessories. Only use accessories
specifi cally recommended for this tool. Others
may be hazardous.
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely.
WARNING To reduce the risk of injury,
do not grasp the bit while the chuck is rotat-
ing or while the bit is falling from the chuck.

SYMBOLOGY
SPECIFICATIONS OPERATION
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
damage to the tool.
1. For rotation only, 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
hammering only, 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.
Starting and Stopping
1. To start the tool, grasp the handle fi rmly and pull
the trigger.
2. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Using the Control Switch
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.
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.
Cold Starting
If this tool is stored for a long period of time or
at cold temperatures, it may not hammer ini-
tially because the lubrication has become stiff.
To warm up the tool:
1. Insert and lock a bit or chisel into the tool.
2. Pull the trigger and apply force to the bit or chisel
against a concrete or wood surface for a few
seconds. Release the trigger
3. Repeat until the tool starts hammering. The cold-
er the tool is, the longer it will take to warm up.
Using Rotary Percussion Core Bits
Core Bits are useful for drilling large or long holes
in concrete. MILWAUKEE Heavy-Duty 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. Thread
the adapter shank to the rear of the core bit.
2. Push the guide plate
onto the pointed end
of the center pin. In-
sert the center pin and
guide plate assembly
into the core bit. Be
sure the small end of
the center pin is se-
curely placed into the
hole in the center of the
core bit.
F o r L H S s y s t e m s ,
screw the threaded
end of the centering bit
into the core bit.
NOTE: If using an ex-
tension, fi rst thread the
adapter shank to the
extension. Then thread the core bit to the exten-
sion.
3. Insert the adapter into the nose of the tool as
described in “Installing Bits and Chisels”. Set the
knob to the "hammering
with rotation" setting.
4. Press the centering
bit fi rmly against your
center mark, hold the
tool fi rmly and pull the
trigger.
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. 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.
