Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle(s) rmly 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 rmly 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 o 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 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.
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 designed for fast,
accurate drilling with combined hammering and
rotary action.

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 mark, hold
the tool rmly and pull the trigger.
NOTE: If a center pin and guide
plate are not available, use a
template or notched board to start the hole.
4. After drilling to about the depth of the core bit teeth,
remove the center pin and guide plate from the
core bit. Resume drilling.
5. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briey
in forward to loosen the core bit from the adapter.
NOTE: To make holes deeper than 3", remove the
core bit, break and remove the core. Resume drilling.
