Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle(s) 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.
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.
Using Rotary Percussion Core Bits
Core bits are useful for drilling larger holes for conduit
and pipe. MILWAUKEE Thin Wall Core Bits have
heat-treated steel bodies with durable carbide tips.
These core bits are specially de-
signed 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. Screw
the threaded end of the adapter
into the rear of the core bit.
NOTE: For core bits 1- 1/4" and
larger, 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 center of the core
bit.
2. Insert the adapter into the nose of
the tool as described in "Installing
Bits". Set the hammer/drill shift
knob to hammering with rotation.
3. Press the center pin firmly against your center

Keep your tool in good repair by adopting a regular
maintenance program. Inspect your tool for issues
such as undue noise, misalignment or binding of
moving parts, breakage of parts, or any other condi-
tion that may affect the tool operation. Return the tool

ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or
combustible solvents around tools.
