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 accord-
ance 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 insulation
system which satisfi es OSHA requirements and
complies with the applicable standards of Under-
writers Laboratories, Inc., the Canadian Standard
Association and the National
Electrical Code. Double Insu-
lated 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 Cana-
da) 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 changing or re-
moving accessories. Only use accessories
specifi cally recommended for this tool. Others
may be hazardous.
WARNING To reduce the risk of injury,
always use a side handle when using this tool.
Always brace or hold securely.
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.
Setting the Depth Gauge
1. Press in the clamping lever.
2. Slide the depth gauge rod backward or forward
until it is set for the desired depth.
NOTE: The drilling depth is the distance between
the tip of the bit and the tip of the rod.
3. Release the clamping lever.
WARNING To reduce the risk of injury
do not grasp the bit while the chuck is rotat-
ing or while the bit is falling from the chuck.
WARNING To prevent personal injury,
always remove the chuck key from the chuck
after each use.
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 capacity of the drill
because gear damage or motor overloading 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 counterclock-
wise.
OPERATION
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.
WARNING To reduce the risk of injury,
keep hands and cord away from the bit and
all moving parts.
WARNING To reduce the risk of injury,
wear safety goggles or glasses with side shields.
Selecting Action
MILWAUKEE Hammer-Drills have two settings:
drilling and hammer-drilling.
1. For drilling, turn the hammer-drill lever towards
the drill symbol .
2. For hammer-drilling, turn the hammer-drill lever
towards the hammer symbol .
NOTE: To engage the hammering mechanism,
maintain pressure on the bit. When pressure on
the bit is released, the hammering action will stop.
Using Forward/Reverse Lever
The forward/reverse lever can only be adjusted
when the trigger is not pressed. Always allow the
motor to come to a complete stop before using the
forward/reverse lever.
1. For forward (clockwise) rotation, push the for-
ward/reverse lever to the
left (when viewed from the
back of the tool) as shown.
2. For reverse (counter-
clockwise) rotation, push
the forward/reverse lever
to the right (when viewed
from the back of the tool)
as shown. Allow the motor to come to a full stop
before reversing.
NOTE: When hammer-drilling, use the tool in for-
ward rotation (clockwise) only.
