GENERAL POWER TOOL SAFETY WARNINGS

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure

to follow the warnings and instructions may result in electric shock, fi re and/or serious
injury. Save all warnings and instructions for future reference. The term "power
tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.

• Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

• Do not operate power tools in explosive atmos­pheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

• Keep children and bystanders away while
operating a power tool. Distractions can cause

you to lose control.

ELECTRICAL SAFETY

WORK AREA SAFETY

• 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. Unmodifi ed plugs and matching outlets will

reduce risk of electric shock.

• Avoid body contact with earthed or 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 wet condi­tions. Water entering a power tool will increase

the risk of electric shock.

• 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.

• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use

of a cord suitable for outdoor use reduces the risk
of electric shock.

• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit inter­rupter (GFCI) protected supply. Use of an GFCI

reduces the risk of electric shock.

PERSONAL SAFETY

• 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 infl uence of drugs, alcohol or medi-
cation. A moment of inattention while operating

power tools may result in serious personal injury.

• Use personal protective equipment. Always
wear eye protection. Protective equipment such

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

• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with

your fi nger on the switch or energising power tools
that have the switch on invites accidents.

• Remove any adjusting key or wrench 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 footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.

• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

• Do not force the power tool. Use the correct
power tool for your application. The correct

POWER TOOL USE AND CARE

power tool will do the job better and safer at the
rate for which it was designed.

• 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.

• 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 pre-

ventive safety measures reduce the risk of starting
the power tool accidentally.

• Store idle power tools out of the reach of chil­dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the

hands of untrained users.

• 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.

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

• Use the power tool, accessories and tool bits
etc. in accordance with these instructions, 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

• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power

tool is maintained.

SPECIFIC SAFETY RULES

• Wear ear protectors when impact drilling.

Exposure to noise can cause hearing loss.

Use auxiliary handle(s), if supplied with the

•

tool. Loss of control can cause personal injury.

2

• Hold power tool by insulated gripping surfaces,

when performing an operation where the cutting
accessory may contact hidden wiring or its
own cord. Cutting accessory contacting a “live”

wire may make exposed metal parts of the power
tool “live” and could give the operator an electric
shock.

• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.

• 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 chemically-treated

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 spe­cially designed to fi lter out microscopic particles.

GROUNDING

WARNING Improperly connecting the

grounding wire can result in the risk of elec­tric 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 ac­cordance with all codes and
ordinances. The plug and outlet
should look like those in Figure A.

Fig. 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
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.

ASSEMBLY

WARNING T o reduce the risk of injury ,

always unplug tool before attaching or remov­ing 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.

EXTENSION CORDS

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.

APPLICATIONS

ACCESSORIES

MAINTENANCE

WARNING T o reduce the risk of injury,

wear safety goggles or glasses with side
shields. Unplug the tool before changing
accessories or making adjustments.

Selecting Action

MILWAUKEE Hammer-Drills have two settings:
drilling and hammer-drilling.

1. For drilling, turn the hammer-drill lever to the
drill symbol.

2. For hammer-drilling, turn the hammer-drill lever
to 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 forward/reverse
lever to the left
(when viewed from
the back of the tool)
as shown.

2. For reverse (counterclockwise) 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 for­ward rotation (clockwise) only.

Selecting Speed (Cat. No. 5387-20 only)

The speed can only be changed when the tool is
at a complete stop.

1. For high torque/low speed (up to 1000 rpm),
turn the speed selector to position 1.

2. For low torque/high speed (up to 2500 rpm),
turn the speed selector to position 2.

Starting, Stopping & Controlling Speed

1. To start the tool, pull trigger.

2. To stop the tool, release trigger.

3. To vary the speed, increase or decrease pres­sure to trigger. The further the trigger is pulled,
the greater the speed.

Operating

Position the tool, grasp the handles fi rmly and pull
the trigger. Always hold or brace the tool securely
using both handles and maintain control. This tool
has been designed to achieve top performance with
only moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling deep
holes, pull the bit partially out of the hole while the
tool is running to help clear dust. Do not use water
to settle the dust since it will clog the bit fl utes and
tend to make the bit bind in the hole.

Reverse

WARNING T o reduce the risk of electric

shock, check work area for hidden pipes and
wires before drilling.

Drilling in Wood, Composition Materials and
Plastic

When drilling in wood, composition materials and
plastic, select the drill operating mode. Start the drill
slowly, gradually increasing speed as you drill. Se­lect low speeds for plastics with a low melting point.

Drilling in Metal

When drilling in metal, select the drill operating
mode. Use high speed steel twist drills or hole saws.
Use a center punch to start the hole. Lubricate drill
bits with cutting oil when drilling in iron or steel. Use
a coolant when drilling in nonferrous metals such
as copper, brass or aluminum. Back the material
to prevent binding and distortion on breakthrough.

Drilling in Masonry

When drilling in masonry, select the hammer-drill
operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder
block requires little pressure. Hard materials like
concrete require more pressure. A smooth, even
fl ow of dust indicates the proper drilling rate. Do
not let the bit spin in the hole without cutting. Do
not use water to settle dust or to cool bit. Do not
attempt to drill through steel reinforcing rods. Both
actions will damage the carbide.
