Selecting Hammer, Drill or Drive Action
MILWAUKEE Hammer-Drills have three
operating modes: drilling with hammering
action, drilling only, and driving screws.
MILWAUKEE Driver Drills have two operating
modes: drilling only and driving screws. To
set the operating mode, rotate the application
selector collar and torque selector collar to
the desired symbols.
1. To use the hammer-drilling mode
(Cat. No. 2611-20 only), rotate the
application selector collar until the
hammer symbol appears in line
with the arrow. Apply pressure to the bit
to engage the hammering mechanism.
NOTE: The number selected on the
torque collar has no effect on operation
of the drill in hammer mode.

NOTE: When using carbide bits, do not
use water to settle dust. Do not attempt
to drill through steel reinforcing rods.
This will damage the carbide bits.
2. To use the drilling only mode, rotate
the application selector collar until the
drill symbol appears in line with
the arrow.
NOTE: The number selected on the
torque collar has no effect on operation
of the drill in drilling mode.

3. To use the driving screws mode rotate
the application selector collar until the
drive symbol appears in line with the
arrow. Then rotate the torque selector
collar until the desired clutch setting
appears in line with the arrow.

To Drive Screws
The adjustable clutch, when properly
adjusted, will slip at a preset torque to
prevent driving the screw too deep into
different materials and to prevent damage
to the screw or tool.
The torque specifi cations shown here are
approximate values.

1 - 5 0 - 16 in. lbs.

NOTE: Because the above settings are only
a guide, use a piece of scrap material to test
the different clutch positions before driving
screws into the workpiece.
Using Control Switch
The control switch may be set to three
positions: forward, reverse and lock. Due to
a lockout mechanism, the control switch can
only be adjusted when the ON/OFF switch
is not pressed. Always allow the motor to
come to a complete stop before using the
control switch.
For forward (clockwise) rotation, push in
the control switch from the right side of
the tool. Check the direction of rotation
before use.
6
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.

APPLICATIONS
WARNING
To reduce the risk
of electric shock, check work area for
hidden pipes and wires before drilling
or driving screws.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, select the drill-only operating
mode. Start the drill slowly, gradually
increasing speed as you drill. When drilling
into wood, use wood augers or twist drill bits.
Always use sharp bits. When using twist drill
bits, pull the bit out of the hole frequently to
clear chips from the bit fl utes. To reduce the
chance of splintering, back work with a piece
of scrap wood. Select low speeds for plastics
with a low melting point.
Drilling in Metal
When drilling in metal, select the drill-
only operating mode. Use high speed steel
twist drills or hole saws. Use a center punch
to start the hole. Lubricate drill bits with
cutting oil when drilling in iron or steel. Use
a coolant when drilling in nonferrous metals
such as copper, brass or aluminum. Back the
material to prevent binding and distortion on
breakthrough.
Starting, Stopping and Controlling
Speed
1. To start the tool, grasp the handle fi rmly
and pull the trigger.
NOTE: An LED is turned on when the
trigger is pulled.
2. To vary the speed, increase or decrease
the pressure on the trigger. The further
the trigger is pulled, the greater the
speed.
3. To stop the tool, release the trigger.
Make sure the bit comes to a complete
stop before laying the tool down.
Drilling
Place the bit on the work surface and apply
firm pressure before starting. Too much
pressure will slow the bit and reduce drilling
effi ciency. Too little pressure will cause the
bit to slide over the work area and dull the
point of the bit.
If the tool begins to stall, reduce pressure
slightly to allow the bit to regain speed. If
the bit binds, reverse the motor to free the
bit from the workpiece.
Drilling in Masonry
When drilling in masonry, select the
hammer-drill operating mode. Use high
speed carbide-tipped bits. Drilling soft
masonry materials such as cinder block
requires little pressure. Hard materials like
concrete require more pressure. A smooth,
even fl ow of dust indicates the proper drilling
rate. Do not let the bit spin in the hole without
cutting. Do not use water to settle dust or
to cool bit. Both actions will damage the
carbide.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into
thick or hard materials. Select the
driving screws mode. Set the torque selector
collar to the proper position and set the
speed to low. Use the proper style and size
screwdriver bit for the type of screw you are
using. With the screwdriver bit in the screw,
place the tip of the screw on the workpiece
and apply fi rm pressure before pulling the
trigger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause perma-
nent damage to tool or battery pack.
