Using the Chisel Lock
To activate the chisel lock:
1. Set the tool to chisel mode.
2. Pull and hold the trigger while sliding the chisel
lock button to the left.
3. Release trigger.
To deactivate the chisel lock, pull the trigger again.

Operating
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.
NOTE: The tool will shut off and the service indicator
will flash if the handle begins to rotate during use.
Cycle through the trigger to continue operating.
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.

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 colder
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. Insert the
center pin and guide
plate assembly into the
core bit. Be sure the
small end of the center
pin is securely placed
into the hole in the cen-
ter 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 extension, first thread the
adapter shank to the extension. Then thread the
core bit to the extension.
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
firmly against your cen-
ter mark, hold the tool

N O T E :
I f

stud is used, or a cen-
ter pin and guide plate
are not available, use
a template or notched
board to start the hole.
5. Start the tool. After drill-
ing to about the depth
of the core bit teeth,
remove the center pin
and guide plate from
the core bit (not nece-
sary for LHS system).
Resume drilling.
6. To change the core bit,
hold the tool upwards, pointing it away from your
body, and run it briefly in forward to loosen the
core bit from the adapter.
