GENERAL SAFETY RULES-FOR ALL BATTERY OPERATED TOOLS

WARNING

READ ALL INSTRUCTIONS

Failure to follow all instructions listed below may result in electric shock, re and/or

serious injury. The term "power tool" in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

WORK AREA SAFETY

1. Keep work area clean and well lit.

Cluttered or dark areas invite acci­dents.

2. Do not operate power tools in ex-

plosive atmospheres, such as in the

presence of ammable liquids, gases,

or dust. Power tools create sparks which
may ignite the dust or fumes.

3. Keep children and bystanders away
while operating a power tool. Distrac­tions can cause you to lose control.

ELECTRICAL SAFETY

4. Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adapter plugs
with earthed (grounded) power tools.

Unmodied plugs and matching outlets

will reduce risk of electric shock.

Avoid body contact with earthed or

5.

grounded surfaces such as pipes,
radiators, ranges and refrigerators.

There is an increased risk of electric shock
if your body is earthed or grounded.

Do not expose power tools to rain or

6.
wet conditions. Water entering a power
tool will increase the risk of electric
shock.

7. Do not abuse the cord. Never use the

cord for carrying, pulling, or unplug­ging the power tool. Keep cord away
from heat, oil, sharp edges, or mov­ing parts. Damaged or entangled cords

increase the risk of electric shock.

8. When operating a power tool out-

doors, use an extension cord suitable
for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of elec­tric shock.

PERSONAL SAFETY

9. Stay alert, watch what you are do­ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired or

under the inuence of drugs, alcohol

or medication. A moment of inattention
while operating power tools may result
in serious personal injury.

Use safety equipment. Always wear

10.
eye protection. Safety equipment such
as dust mask, non-skid safety shoes,
hard hat, or hearing protection used
for appropriate conditions will reduce
personal injuries.

Avoid accidental starting. Ensure the

11.

switch is in the off-position before plug­ging in. Carrying tools with your nger on

the switch or plugging in power tools that
have the switch on invites accidents.

Remove any adjusting key or wrench

12.
before turning the power tool on. A
wrench or a key left attached to a rotat­ing part of the power tool may result in
personal injury.

Do not overreach. Keep proper foot-

13.
ing and balance at all times. This
enables better control of the power tool
in unexpected situations.

14. Dress properly. Do not wear loose

clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery, or long

hair can be caught in moving parts.

15. If devices are provided for the connec-

tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these de-

vices can reduce dust-related hazards.

POWER TOOL USE AND CARE

16. Do not force the power tool. Use the
correct power tool for your applica­tion. The correct power tool will do the

job better and safer at the rate for which
it was designed.

17. Do not use the power tool if the switch
does not turn it on and off. Any power tool
that cannot be controlled with the switch is
dangerous and must be repaired.

18. Disconnect the plug from the power

source and/or the battery pack from

the power tool before making any
adjustments, changing accessories,
or storing power tools. Such preven-

tive safety measures reduce the risk of
starting the tool accidentally.

19. Store idle power tools out of the reach

of children and do not allow persons
unfamiliar with the power tools or
these instructions to operate power
tools. Power tools are dangerous in the

hands of untrained users.

20. Maintain power tools. Check for

misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool's operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by

poorly maintained power tools.

21. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.

22. Use the power tool, accessories and

tool bits etc., in accordance with
these instructions and in the manner
intended for the particular type of
power tool, taking into account the
working conditions and the work to
be performed. Use of the power tool for

operations different from those intended
could result in a hazardous situation.

SERVICE

23. Have your power tool serviced by a

qualied repair person using only

identical replacement parts. This will
ensure that the safety of the power tool
is maintained.

SPECIFIC SAFETY RULES

1. Use auxiliary handles supplied with
the tool. Loss of control can cause

personal injury.

2. Wear ear protectors with impact
drills. Exposure to noise can cause
hearing loss.

3. Hold power tools by insulated grip-

ping 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.

4 Maintain labels and nameplates.

These carry important information.
If unreadable or missing, contact a
MILWAUKEE service facility for a free
replacement.

5. WARNING! Some dust created by
power sanding, sawing, grinding, drill­ing, and other construction activities
contains chemicals known to cause
cancer, birth defects or other reproduc­tive harm. Some examples of these
chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement
and other masonry products, and

• arsenic and chromium from chemically­treated lumber.

Your risk from these exposures varies,

depending on how often you do this
type of work. To reduce your exposure
to these chemicals: work in a well ven­tilated area, and work with approved
safety equipment, such as those dust

masks that are specically designed to
lter out microscopic particles.

GROUNDING

WARNING

3

4

Improperly connecting the grounding
wire can result in the risk of electric
shock. Check with a quali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 t the outlet,

have a proper outlet installed by a

quali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
accordance 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 satisfies
OSHA requirements and complies with
the applicable standards of Underwriters
Laboratories, Inc., the Canadian Standard
Association and the National Electrical
Code. Double Insulated tools may be used
in either of the 120 volt outlets shown in
Figures B and C.

EXTENSION CORDS

TOOL ASSEMBLY

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 out-

doors, be sure it is marked with the suf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

qualied person before using it.

• Protect your extension cords from sharp
objects, excessive heat and
damp or wet areas.

WARNING

To reduc e the risk of i njury,
always unplug tool before attaching
or removing accessories or making

adjustments. Use only specically

recommended accessories. Others
may be hazardous.

Installing Bits into Keyed Chucks (Fig.1)

Fig. 1

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. Then, 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 counterclockwise.

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 (Fig. 2)

The spade handle can be attached to the tool
in three positions (Fig. 2). Remove the hex
head screws which secure the handle. Re­move the handle 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 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 speci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.

To reduce the risk of injury, wear
safety goggles or glasses with side
shields. Unplug the tool before
changing accessories or making
adjustments.

WARNING

To reduce the risk of personal injury
when drilling, always hold tool by the
insulated 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 xed object in

preparation for a sudden reaction.
When drilling in LO with a two speed
drill, always brace the drill against a

solid 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.

The operator should also prepare for a
sudden reaction by holding securely using
the pipe handle or bracing against a solid

xed object.

To reduce the chance of bit binding

• 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 specic

purposes.

• Use the proper speed for the size
bit. Larger bits should be run at the
lower speed. Driving larger bits at high
speeds will increase the chance of the
bit binding and increase the chance of
reaction.

• Avoid drilling warped, wet, knotty, and
or pitchy material if possible.

• Avoid drilling in material that you suspect
contains hidden nails or other things that
may cause the bit to bind.

The direction of reaction is always opposite
of the direction of bit rotation.

Reaction is even more likely to occur when
enlarging already existing holes and at the
point when the bit breaks through the other
side of the material.

When drilling in forward, the bit will rotate in
a clockwise direction. If the bit binds in the
hole, the bit will come to a sudden stop and
drill will suddenly react in a counterclockwise
direction.

Shifting Speeds (Fig. 8)

Cat. No. 1675-1 has
a gear shift lever on
the right side of the
gear case.

The hig h se t t ing
(1200 RP M HI) is
the low torque setting
and is designed for
driving Selfeed bits
1-3/8" in diameter
and smaller.

The low setting (300
RPM LO) is the high
torque setting and is
designed for driving
Selfeed bits 1-1/2" in
diameter and larger.

Reversing (Fig. 9)

Fig. 9

A reversing switch is located below the trig­ger switch for removal of bits from holes.
Permit the motor to come to a complete stop
before reversing. Reversing the tool with the
gears in motion may cause severe damage.
When removing selfeed bits from partially

drilled holes, a ick of the trigger switch

will free the threaded pilot screw. When the
threads are loose, lift the bit from the work­piece with the motor stopped.

Fig. 8

Drilling

Before drilling, clamp down the material
securely. A poorly secured piece of material
may result in personal injury or inaccurate
drilling. When drilling in light gauge metal or
wood, use a wooden block to back up the ma­terial to prevent damage to the workpiece.

Mark the center of the hole to be drilled with
a center punch to give the bit a start and to
prevent it from "walking." Lubricate the drill
bit with cutting oil when drilling iron or steel.
Use a coolant when drilling nonferrous met­als such as copper, brass or aluminum.

To start a selfeed bit, run the threaded feed

screw into the work by icking the trigger

switch, permitting the bit to coast until the
teeth contact the work surface. Align the bit
properly before proceeding. This will reduce
cocking and jamming when starting. To re­duce jamming on breakthrough, decrease
the drilling pressure when the feed screw
point breaks through the workpiece. Proceed
with steady, even pressure.

WARNING

To reduce the risk of injury, always
wear eye protection.

Chuck Removal

To remove the chuck from the drill:

1. Unplug tool.

2. Fully open the chuck jaws

3. Remove the left-handed thread screw
from inside the chuck by turning it clock­wise.

4. Pull the chuck off of the spindle.

NOTE: If the chuck does not pull off of

the spindle easily, tap the side of the
chuck with a hammer to loosen it. If this
doesn't work, contact a MILWAUKEE
service center.

MAINTENANCE

WARNING

To reduce the risk of injury, always un­plug your tool before performing any
maintenance. Never disassemble the
tool or try to do any rewiring on the
tool's electrical system. Contact a
MILWAUKEE service facility for ALL
repairs.

Maintaining Tools

Keep your tool in good repair by adopting a
regular maintenance program. Before use,
examine the general condition of your tool.
Inspect guards, switches, tool cord set and
extension cord for damage. Check for loose
screws, misalignment, binding of moving
parts, improper mounting, broken parts and
any other condition that may affect its safe
operation. If abnormal noise or vibration oc­curs, turn the tool off immediately and have
the problem corrected before further use.
Do not use a damaged tool. Tag damaged
tools “DO NOT USE” until repaired (see
“Repairs”).

Under normal conditions, relubrication is not
necessary until the motor brushes need to
be replaced. After six months to one year,
depending on use, return your tool to the
nearest MILWAUKEE service facility for the
following:

• Lubrication

• Brush inspection and replacement

• Mechanical inspection and cleaning
(gears, spindles, bearings, housing,
etc.)

• Electrical inspection (switch, cord,
armature, etc.)

• Testing to assure proper mechanical and
electrical operation

WARNING

To reduce the risk of injury, electric
shock and damage to the tool, never

immerse your tool in liquid or allow a
liquid to ow inside the tool.

Cleaning

Clean dust and debris from vents. Keep
the tool handles clean, dry and free of oil
or grease. Use only mild soap and a damp
cloth to clean your tool since certain cleaning
agents and solvents are harmful to plastics
and other insulated parts. Some of these
include: gasoline, turpentine, lacquer thinner,
paint thinner, chlorinated cleaning solvents,
ammonia and household detergents con-

taining ammonia. Never use ammable or

combustible solvents around tools.

Repairs

If your tool is damaged, return the entire tool
to the nearest service center.
