OPERATION
WARNING
To reduce the risk of injury, keep
hands away from the bit and all mov-
ing parts. Always wear safety goggles
or glasses with side shields. Always
remove the chuck key from the chuck
after each use.
Installing Bits into Keyed Chuck
Fig. 5
Tighten
Loosen
1.
Open the chuck jaws wide enough to
insert the bit. Be sure the bit shank
and chuck jaws are clean. Dirt particles
may prevent the bit from lining up
properly.
2.
When using drill bits, insert the bit into
the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the bot-
tom. Tighten the chuck jaws by hand to
align the bit.
When using screwdriver bits, insert the
bit far enough for the chuck jaws to grip
the bit shank. Tighten the chuck jaws by
hand to align the bit.
3.
Place the chuck key in each of the three
holes in the chuck, turning it clockwise
as shown. Tighten securely.
4.
To remove the bit, insert the chuck key
into one of the holes in the chuck and
turn it counterclockwise.
Forward/Reverse/Trigger Lock Switch
To set the direction of bit rotation or lock the
trigger, move the forward/reverse/trigger lock
switch to the following positions (Fig. 6):
Fig. 6
For forward rotation (clockwise):Move the
switch to the right." " will be displayed above
the switch. To vary the speed in forward
rotation, increase or decrease pressure on
the trigger.
For reverse rotation (counter-clockwise):
Move the switch to the left. " " will be dis-
played above the switch. To vary the speed
in reverse rotation, increase or decrease
pressure on the trigger.
To lock the trigger: Move the switch to the
center. " " will be displayed above the switch.
The trigger will not work while the switch is in
the locked position. Always lock the trigger
and remove the battery pack before perform-
ing maintenance and changing accessories.
Lock the trigger when storing the tool and
when the tool is not in use.
Starting, Stopping and Controlling
Speed
1.
To start the tool, grasp the handle fi rmly
and pull the trigger.
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 tool comes to a complete
stop before laying the tool down.

WARNING
To reduce the risk of personal injury,
hold the tool securely. Brace tools
with side handles as shown (Fig. 7, 8
& 9). If the bit binds, the tool will be
forced in the opposite direction. Bits
may bind if they are misaligned or
when breaking through a hole. Wood
boring bits can also bind if they run
into nails or knots.

Electric Brake
The electric brake engages when the trigger
is released, causing the bit to stop and allow-
ing you to proceed with your work. Generally,
the bit stops within two seconds. However,
there may be a delay between the time
you release the trigger and when the brake
engages. Occasionally the brake may miss
completely. If the brake misses frequently,
the tool needs servicing by an authorized
MILWAUKEE service facility.
Cold Weather Operation
The V28 Lithium-Ion battery pack can be
used in temperatures down to -4°F. When
the battery pack is very cold, it may pulse for
the fi rst minute of use to warm itself up. Put
the battery pack on a tool and use the tool in
a light application. After about a minute, the
pack will have warmed itself up and operate
normally.
APPLICATIONS
Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always use
sharp bits.
Drilling
1.
Before drilling, be sure the workpiece is
clamped securely. Use backing material
to prevent damage to the workpiece dur-
ing breakthrough.
2.
When starting a hole, place the drill bit on
the work surface and apply fi rm pressure.
Begin drilling at a slow speed, gradually
increasing the speed as you drill.
3.
Always apply pressure in line with the
bit. Use enough pressure to keep the
drill biting, but do not push hard enough
to stall the motor.
4.
Reduce pressure and ease the bit
through the last part of the hole. While
the tool is still running, pull the bit out of
the hole to prevent jamming.
