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: 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 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.

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

Installing Bits into Keyed Chucks

1. Unplug tool.

2. 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.

3. Insert the bit into the

chuck. Center the bit in

the chuck jaws and lift it about 1/16" off of the

bottom. Tighten the chuck jaws by hand to align

the bit.

4. Place the chuck key in each of the three holes in

the chuck, turning it clockwise. Tighten securely.

5. To remove the bit, insert the chuck key into one

of the holes in the chuck and turn it counterclock-

wise.

Bit Selection

• Use sharp bits. Sharp bits are less likely to bind

when drilling.

• Use the proper bit for the job. There are many

types of bits designed for speciﬁ c purposes. Check

the information on the bit's packaging for proper

usage.

• Do not use bits larger than the rated capacity of the

drill. Gear damage or motor overload may result.

Pipe Handle

The pipe handle may be used on either side of the

tool. Thread pipe handle into one of the threaded

holes in the motor housing.

Spade Handle

The spade handle can be

attached to the tool in three

positions. Remove the hex

head screws which secure

the handle. Remove the han-

dle and move it to the desired

position. To mount the handle

in position C, it is necessary

to reverse the mounting holes

by turning the handle around.

Bit binding

WARNING To reduce the risk of injury,

wear safety goggles or glasses with side

shields.

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

personal injury when drilling, hold tool by in-

sulated gripping surfaces when performing an

operation where the cutting tool may contact

hidden wiring or its own cord. Contact with a

"live" wire will make exposed metal parts of

the tool "live" and shock the operator.

WARNING When drilling with a single

speed drill or in HI with a two speed drill,

always hold the drill securely using the pipe

handle, or brace the drill against a solid ﬁ xed

object in preparation for a sudden reaction.

When drilling in LO with a two speed drill,

always brace the drill against a solid ﬁ xed

object in preparation for a sudden reaction.

When drilling, never use your body to brace

drill.

Never put your hands (or other body parts)

between the part of the drill being braced and

the object it is being braced against. Hands

(or other body parts) that are in the path of the

reaction can be pinched, crushed and broken.

If the bit binds, the drill will suddenly react in the

opposite direction of the rotation of the bit. Figure

3 shows the path of reaction (B) if the drill bit binds

while being driven in forward (A). The operator

should reduce the chances of a sudden reaction

by following the instructions listed below.
