POWER TOOL USE AND CARE
SERVICE
SPECIFIC SAFETY RULES
•Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
•Do not operate power tools in explosive at-
mospheres, such as in the presence of flam-
mable liquids, gases or dust. Powertoolscreate
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.
•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. Unmodified 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. Thereisanincreasedrisk of electric
shock if your body is earthed or grounded.
•Do not expose power tools to rain or wet con-
ditions. 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 residual current device
(RCD) protected supply. Use of anRCD reduces
the risk of electric shock.
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 will do the job better and safer at the
rate for which it was designed.
•Do not use thepowertooliftheswitchdoesnot
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
preventive safety measures reduce the risk of
starting the power tool accidentally.
•Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Powertools are dangerous inthe
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. Manyaccidents
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,
takingintoaccounttheworkingconditionsand
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
•Stay alert, watch what you are doing and use
common sensewhen operatinga powertool. Do
not usea power toolwhile youare tiredor under
theinfluenceof drugs, alcohol or medication. 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
hearingprotection 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. Carryingpowertoolswith
yourfingeron the switch or energisingpowertools
that have the switch on invites accidents.
•Remove any adjusting key or wrench before
turning the power tool on. Awrench or a key left
•Have your power tool serviced by a qualified
repair person using only identical replacement
parts. Thiswill ensure that thesafetyof the power
tool is maintained.
•Hold tools byinsulatedgrippingsurfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord.
Contactwith a “live” wire will make exposedmetal
parts of the tool “live” and shock the operator.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
•WARNING: Somedustcreatedbypowersanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.

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
appropriateoutlet, 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
complieswith theapplicablestandardsof Underwrit-
ers Laboratories, Inc., the Cana-
dianStandardAssociationand the
National Electrical Code. Double
Insulated tools may be used in ei-
therofthe120voltoutletsshownin

GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of elec-
tric shock. Check with a qualified 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
fit the outlet, have a proper outlet installed by
a qualified 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
thesupplyoutlet increases, you must usea heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage,resulting in loss ofpower and possibletool
damage.Refer to thetable 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
sureitismarkedwiththesuffix“W-A”(“W”inCana-
da)to indicate that it isacceptable 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
qualified 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 five volts at
150% of the rated amperes.

WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifically recommended accessories.
Others may be hazardous.
In all cutting operations, keep the shear at right
angles to the surface of the workpiece and the
back as low as possible for fast cutting. Use an
evenforwardpressure to insure efficientoperation.
To obtain the least amount of metal distortion and
smoothestedge,keep waste portion of metaltothe
right of the shear. Cutting line should be lubricated
before cutting 16 gauge steel or heavier.
Blade Clearance
The clearance between the blades is not set at the
time of manufacture. Cleaner edges and longer
bladelife will result when the gap isproperly set for
the gauge of the metal to be cut. Use 20% of the
material thickness for an approximate blade clear-
ancesetting.Make minor adjustments, if necessary.
To adjust the gap:
1. Unplug the tool and loosen the lower blade
clampling screw 1/3 of a turn with the socket
wrench provided.
2. Turn the blade positioning screw, on the side of
the yoke, in or out to decrease or increase the
gap.
NOTE: If lowerblade clamping screw is loose
more than a 1/3 of a turn, the blade clearwance
may be misadjusted.
3. Measure the clearance with the feeler gauge
provided.
4. When the desired setting has been achieved,
tighten the blade clamping screw and locking
nut on the blade positioning screw.
* Make minor adjustments if necessary.
WARNING To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
