Grounded Tools: Tools with Three Prong Plugs
Tools marked “Grounding Required” have a three
wire cord and three prong grounding plug. The
plug must be connected to a properly grounded
outlet (See Figure A). If the tool should electrically
malfunction or break down, grounding provides a
low resistance path to carry electricity away from
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire in the
cord must be the only wire connected to the tool's
grounding system and must never be attached to
an electrically “live” terminal.
Your tool must be plugged into
an appropriate outlet, properly
installed and grounded in ac-
cordance with all codes and
ordinances. The plug and outlet
should look like those in Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require
grounding. They have a special double insula-
tion system which satisfi es OSHA requirements
and complies with the applicable standards of
Underwriters Laboratories, Inc.,
the Canadian Standard Asso-
ciation and the National Elec-
trical Code. Double Insulated
tools may be used in either of
the 120 volt outlets shown in
Figures B and C.

GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of elec-
tric shock. Check with a qualifi ed electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the tool. Never remove the
grounding prong from the plug. Do not use
the tool if the cord or plug is damaged. If
damaged, have it repaired by a MILWAUKEE
service facility before use. If the plug will not
fi t the outlet, have a proper outlet installed by
a qualifi ed electrician.
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge cord. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required.
If you are using one extension cord for more than
one tool, add the nameplate amperes and use the
sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure
it is marked with the suffi x “W-A” (“W” in Canada)
to indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a
qualifi ed person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
READ AND SAVE ALL
INSTRUCTIONS FOR FUTURE USE.
* Based on limiting the line voltage drop to fi ve volts at
150% of the rated amperes.

ASSEMBLY
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Removing and Replacing Quik-Lok ® Cords
(Cat. No. 5387-20)
MILWAUKEE's exclusive Quik-Lok
® Cords provide
instant fi eld replacement or substitution.
Fig. 1
1.To remove the Quik-Lok ® Cord, turn the cord nut
1/4 turn to the left and pull it out.
2.To replace the Quik-Lok ® Cord, align the connec
tor keyways and push the connector in as far as it
will go. Turn the cord nut 1/4 turn to the right to lock.
Installing Bits into Keyed Chucks
Be sure that the shank of the bit and the chuck
jaws are clean. Dirt particles may cause the bit
to line up improperly.
Do not use bits larger
than the maximum
recommended ca-
pacity of the drill be-
cause gear damage
or motor overload-
ing may result. For
best performance, be
sure that the bits are
properly sharpened
before use.
1. Unplug the tool.
2. Open the chuck jaws wide enough to insert a bit.
Allow the bit to strike the bottom of the chuck.
Center the bit in the chuck jaws and tighten the
jaws by hand to align the bit.
3. Place the chuck key into each of the three holes
in the chuck, turning it clockwise to tighten the
chuck securely.
NOTE: Never use a wrench or means other than
a chuck key to tighten or loosen the chuck.
4. To remove the bit, insert the chuck key into one of
the holes in the chuck and turn it counterclockwise.

Tighten
Adjusting the Side Handle Position
1. Loosen the side handle by unscrewing the side
handle grip until the side handle rotates freely.
2. Rotate the side handle to the desired position.
3. Tighten the side handle grip securely.
WARNING To prevent personal injury,
always remove the chuck key from the chuck
after each use.
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely.

2. Slide the depth gauge rod backward or forward
until it is set for the desired depth (Fig. 4).
NOTE: The drilling depth is the distance between
the tip of the bit and the tip of the depth gauge
rod.
3. Release the clamping lever.
Setting the Depth Gauge
1. Press in the clamping lever (Fig. 3).
Chuck Removal
This tool is equipped with a threaded spindle to
hold the chuck. Before removing the chuck, unplug
the tool and open the chuck jaws. A left-handed
thread screw is located inside the chuck to pre-
vent the chuck from loosening when the tool is
operated in reverse direction. Remove the screw
by turning it clockwise. To remove the chuck, hold
the tool so that only the side of the chuck rests
fi rmly and squarely on a solid workbench. Insert
the chuck key or
a chuck remover
bar in one of the
keyholes. Turn
the chuck so the
key is at about a
30° angle to the
bench top and
strike the key
sharply with a
hammer so the
chuck turns in
a counterclock-
wise direction
( l o o k i n g f r o m
the front of the
tool). This should
loosen the chuck
from the spindle
which has a right hand thread making it easy to
remove the chuck by hand.
NOTE: When replacing the chuck, always replace
the left hand thread screw in the chuck.
