SAFETY INSTRUCTIONS
A WARNING: BE SURE to read and understand all Instructions. Failure to
follow all Instructions listed below may result In electric shock, fire and/or
serious personal injury.
WORK AREA SAFETY
1. ALWAYS keep your work area clean and well lit. Cluttered benches and dark
areas invite accidents.
2. DO NOT operate power tools In explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes,
3. ALWAYS keep bystanders, children, and visitors away while operating a
power tool. Distractions can cause you to lose control
ELECTRICAL SAFETY
1. Double Insulated tools are equipped with a polarized plug (one blade is
wider than the other.) This plug will fit In a polarized outlet only one way.
If the plug does not fit fully In the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not change
the plug In any way.
2. Double insulation Qeliminates the need for the three-wire grounded power cord
and grounded power supply system. Applicable only to Class II (double insulated)
tools.
3. Before plugging in the tool, BE SURE that the outlet voltage supplied Is within the
voltage martted on the tool's data plate. DO NOT use "AC only" rated tools with a
DC power supply.
4. ALWAYS avoid body contact with grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric shock
If your body Is grounded.
5. If operating the power tool in damp locations is unavoidable, ALWAYS use a
Ground Fault Circuit Interrupter to supply power to your tool. ALWAYS wear
electrician's rubber gloves and footwear in damp conditions.
6. DO NOT expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
7. DO NOT abuse the cord. NEVER use the cord to carry the tools or puli the
plug from the outlet. Keep cord away from heat, oil, sharp edges or moving
parts. Replace damaged cords immediately. Damaged cords increase the risk
of electric shock.
8. When operating a power tool outside, ALWAYS use an outdoor extension cord
marked “W-A” or "W". These cords are rated for outdoor use and reduce the risk
of electric shock.
NOTE: The extension cord must have adequate wire size AWG (American Wire
Gauge) for safe, efficient use. Smaller gauge wires, have greater capacity (16 gauge
wire has more capacity than 18 gauge wire).
SAFETY INSTRUCTIONS cont.
PERSONAL SAFETY
1. ALWAYS stay alert, watch what you are doing and use common sense when
operating a power tool. DO NOT use tool while tired or under the Influence of
drugs, alcohol, or medication. A moment of inattention while operating power
toois may result in serious personai injury,
2. ALWAYS dress properly. DO NOT wear loose clothing or jewelry. Pull back
long hair. Keep your hair, clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught in moving parts.
3. ALWAYS avoid accidental starting. BE SURE switch is in the "Off” position
before plugging in. DO NOT carry tools with your finger on the switch. Carrying
tools with your finger on the switch or plugging in tools that have the switch in the
“On" position invites accidents.
4. ALWAYS remove adjusting keys or wrenches before turning the tool “On”.
A wrench or a key that is left attached to a rotating part of the tool may result in
personal injury.
5. DO NOT overreach. ALWAYS keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in unexpected
situations.
6. ALWAYS use safety equipment. Always wear eye protection. Dust mask,
non-skid safety shoes, hardhat, or hearing protection must be used for appropriate
conditions.
TOOL USE AND CARE SAFETY
1. ALWAYS use clamps or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body
is unstable and may lead to loss of control.
2. DO NOT force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
3. DO NOT use the tool if the switch does not turn it "On” or “Off”. Any tool that
cannot be controlled with the switch is dangerous and must be repaired.
4. ALWAYS disconnect the plug from the power source before making any
adjustments, changing accessories or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
5. ALWAYS store idle tools out of the reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
6. ALWAYS maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools with sharp cutting edges are less likely to bind and are
easier to control.
7. ALWAYS check for misalignment or binding of moving parts, breakage of
parts, and any other condition that may affect the tool's operation. If
damaged, have the tool serviced before using. Many accidents are caused by
poorly maintained tools.
A WARNING; USE OF accessories THAT ARE NOT RECOMMENDED
FOR USE WITH THIS TOOL MAY CREATE A HAZARDOUS CONDITION
8. ALWAYS use only accessories that are recommended for this tool.
Accessories that may be suitable for one tool can become hazardous when used
on another tool.

SAFETY INSTRUCTIONS cont.
SERVICE SAFETY
1. If any part of this saw is missing or should break, bend, or fall In any way; or
should any electrical component fail to perform properly: ALWAYS shut off the
power switch and remove the saw plug from the power source and have the missing,
damaged or failed parts replaced BEFORE resuming operation.
2. Tool service must be performed only at a Sears Parts and Repair Center.
Service or maintenance performed by unqualified personnel could result in a risk of
injury.
SAFETY RULES FOR SAWS
____________________________________________
As. DANGER! Keep hands away from cutting area and blades. Keep your
second hand on the auxiliary handle or motor housing. If both hands are
holding the saw, they cannot be cut by the blades.
1. ALWAYS keep your body positioned to either side of the saw blades, but not
in line with the saw blades.
2. DO NOT reach underneath the work. The guard cannot protect you from the
blades beneath the work.
3. ALWAYS check guard for proper closing BEFORE each use. DO NOT operate
the saw if the guard does not move freely and close instantly. Never clamp or
tie the blade guard In the open position. If the saw is accidentally dropped, the
guard may be bent. Raise the guard and make sure that it moves freely and does
not touch the blades or any other part.
4. ALWAYS check the operation and condition of the guard spring. If the guard
and the spring are not operating properly, they MUST be serviced before use.
The blade guard may operate sluggishly, due to damaged parts, gummy deposits,
or a buildup of debris.
5. The guard should be retracted manually ONLY for making special cuts, such
as pocket or compound cuts. ALWAYS raise the guard by retracting the
handle. As soon as the blade enters the material, the guard MUST be
released. For all other sawing, the guard should operate automatically.
6. ALWAYS make sure that the guard is covering the blades BEFORE placing the
saw down on a work bench or floor. An unprotected moving blades will cause the
saw to walk backwards, cutting whatever Is in its path. Make note of the time it takes
for the blades to stop spinning after the switch is released.
7. NEVER hold the piece being cut In your hands or across your legs, it is
important to support the work property in order to minimize body exposure, blade
binding, or loss of control.
8. ALWAYS hold tool by 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 the exposed metal parts of the tool “live" and
shock the operator,
9. DO NOT leave the saw running when carrying it in your hand,The lower blade
guard may be opened by contact with your clothing. Accidental contact with the
spinning saw blades could result in serious personal injury.
10. DO NOT use the tool If the switch does not turn “On” or "Off”. Any tool that
cannot be controlled with the switch is dangerous and must be repaired.

11. When removing the blades from the tool, ALWAYS wear protective gloves when
grasping the blades or accessory. Accessories may be hot after prolonged use.
KiCKBACK...WHAT CAUSES IT AND WAYS TO PREVENT IT
The Causes of Kickback
1. Kickback is a sudden reaction to a pinched, bound or misaligned saw blades,
which cause the uncontrolled saw to lift up and out of the workpiece and towards
the operator.
2. When the blades are pinched or bound tightly by the kerf closing down, the blades
stall and the motor reaction drives the unit rapidly back towards the operator.
3. If the blades become twisted or misaligned In the cut, the teeth at the back edges
of the blades can dig into the top surface of the wood. This causes the blades to
climb out of the kerf and jump back towards the operator.
4. Kickback is a result of tool misuse and/or incorrect operating procedures or
conditions. It can be avoided by taking the proper precautions, as listed below.
Ways to Prevent Kickback
1. ALWAYS maintain a firm grip with both hands on the saw and position your
body and arms to allow you to resist KICKBACK forces. KICKBACK forces can
be controlled by the operator, if the proper precautions are taken.
2. If the blades are binding, or when you are Interrupting a cut for any reason,
ALWAYS turn off the saw and hold the saw motionless in the material until
the blades come to a complete stop. NEVER attempt to remove the saw from
the work or pull the saw backward while the blades are in motion or
KICKBACK may occur. ALWAYS check and be ready to take corrective action to
eliminate the cause of blade binding.
5. When restarting the saw In the workpiece, ALWAYS center the blades In the
kerf and check to be sure that the saw teeth are not engaged into the
material. If the saw blades are binding, they may walk up or KICKBACK from the
workpiece when the saw is restarted.
4. ALWAYS support large panels to minimize the risk of blades pinching and
KICKBACK. Large panels tend to sag under their own weight. Supports fi/IUST be
placed under the panel on both sides, near the line of cut and near the edge of the
panel..
5. DO NOT use a dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerf which causes excessive friction, blade binding and
KICKBACK,
6. ALWAYS use extra caution when making a “Pocket Cut” Into existing walls or
other blind areas. The protruding blades may cut objects that can cause
KICKBACK.
7. ALWAYS have the saw blades at full speed before contacting workpiece
8. ALWAYS keep your body positioned to either side of the saw blades, but not in line
with the saw blades. KICKBACK could cause the saw to jump backwards towards
the operator. KICKBACK forces can be controlled by the operator, if proper
precautions are taken.
ALWAYS hold tool by 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 the exposed metal parts of the tool "live" and
shock the operator, g

applications and limitations, as well as the specific potential hazards related
to this tool. Following this rule will reduce the risk of electric shock, fire or serious
injury.
2. ALWAYS wear safety glasses or eye shields when using this saw. Everyday
eyeglasses have only Impact-resistant lenses; they are NOT safety glasses.
Following this rule will reduce the risk of serious personal injury.
3. ALWAYS protect your lungs. Wear a face mask or dust mask If the operation
is dusty. Following this rule will reduce the risk of serious personal injury.
4. ALWAYS protect your hearing. Wear hearing protection during extended
periods of operation. Following this rule will reduce the risk of serious persona!
injury.
5. ALWAYS inspect the tool cords periodically and if damaged have them
repaired at your nearest Sears Service Center or other Authorized Service
Facility. ALWAYS be aware of the cord location. Following this rule will reduce
the risk of electric shock or fire.
6. ALWAYS check for damaged parts. Before further use of the tool, a guard or
other part that Is damaged should be carefully checked to determine if it will
operate properly and perform its intended function. Check for misalignment
or binding of moving parts, breakage of parts, and any other condition that
may affect the tooi's operation. A guard or other part that is damaged, shouid
be properly repaired or replaced at a Sears Service Center. Foliowing this rule
will reduce the risk of electric shock, fire or serious injury.
7. DO NOT abuse the cord. NEVER use the cord to carry the tool or pull the
plug from the outlet. Keep cord away from heat, oil, sharp edges or moving
parts. Replace damaged cords Immediately. Damaged cords increase the risk
of electric shock. Following this rule will reduce the risk of electric shock or fire.
8. ALWAYS make sure that your extension cord Is in good condition. When
using an extension cord be sure to use one that Is heavy enough to carry the
current that your tool will draw. A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension 100 feet or less in length. Using an extension
cord that Is over 100 feet Inlength is not recommended. If in doubt, use the
next heavier gauge. Smaller gauge wires, have greater capacity (16 gauge
wire has more capacity than IB gauge wire). An undersized cord will cause a
drop in line voltage, resuiting in loss of power and overheating.
9. DO NOT use the tool while tired or under the Influence of drugs, alcohol or
any medication. Following this rule will reduce the risk of electric shock, fire or
serious personal injury.

UNPACKING
YourTwin Cutter Saw has been shipped completely assembled. Inspect the saw
carefully to make sure that no breakage or damage has occurred during shipping.
If any parts are damaged or missing return the saw to your nearest Sears Store to
have it replaced.
A WARNING: If any parts are missing, DO NOT operate this saw until the
missing parts are replaced. Failure to do so could result in possible serious
personal injury
OPERATION
SAW BLADES
Even the best saw blades will not cut efficiently if they are not kept clean, sharp and
properly set. Using dull blades will place a heavy load on your saw and increase the
danger of kickback. Keep extra blades on hand, so sharp blades are always available.
Gum and wood pitch hardened on your blades will slow your saw down. Use gum
and pitch remover, hot water or kerosene to remove these accumulations.
DO NOT use gasoline.
A WARNING: This Twin Cutter saw uses specially designed 5-in. blades
and no other types or sizes of blades should ever be used. Other types and sizes of
blades will not operate safely in this saw and could result in serious personal injury.
To order extra blades or to replace the blades that came with the saw, see page 21
of this manual for ordering instructions. To install new blades onto to your saw see
the special instructions on pages 17 to 19 of this manual for proper removal and
installation of biades.
BLADE GUARD SYSTEM
The lower blade guard, attached to your saw, is there for your protection and
safety. It should NEVER be altered for any reason. If it becomes damaged or
begins to return siowiy or siuggishly. DO NOT operate your saw untii the
probiem has been corrected or the damaged part has been repiaced. ALWAYS
leave the guard in its correct operating position when using the saw.
A DANGER: When sawing through a
workpiece, the lower blade guard does not
cover the blade on the underside of the
workpiece. Since the biade Is exposed on the
underside of the workpiece, ALWAYS keep
your hands and fingers away from the cutting
area (see Fig. 2). Any part of your body
coming in contact with the moving blade will
result in serious injury.
Lower Blade Guard is in UP position when
making a cut. Blades are exposed on underside
of workpiece.
A WARNING: NEVER use the saw when the guard is not operating properly.
The guard should be checked for correct operation before each use. If you drop your
saw, check the lower blade guard for damage before using.
NOTE: The guard is operating properly when it moves freely and then readily
returns to the closed position. If, for any reason, your lower blade guard does not
close freely, take it to your nearest Sears Repair Center for service before using it.
10
OPERATION cont.
KICKBACK
Kickback occurs when the blades stall rapidly and the saw is driven back towards
you. Blade stalling is caused by any action which pinches the blade in the materia!
being cut.
IMPORTANT: The best guard against kickback Is to avoid dangerous practices.
A DANGER: ALWAYS turn OFF power to saw immediately if the blades bind
or the saw stalls. Kickback could cause you to lose control of the saw. Loss of
control can lead to serious injury.
ALWAYS provide proper support for the workpiece and hold the saw with
both hands
Kickback is Caused By:
1. Twisting the blades while making a cut.
2. Making a cut with a dull, gummed up, or
improperly set blades.
3. Not providing proper support for workpiece.
ALWAYS provide proper support as shown
in Fig. 3.
4. Forcing a cut.
5. Cutting warped or wet lumber.
6 Tool misuse or incorrect operating procedures.
7. Contacting the workpiece with blades at less
than full speed.
To Lessen the Chance of Kickback
1. ALWAYS approach the workpiece with
the saw at an angle of approximately
30® to the workpiece, (see Fig. 4.)
2. ALWAYS make straight cuts.
This will help prevent twisting the
blade in the cut.
3. ALWAYS use clean, sharp and
properly set blades, NEVER make
cuts with dull blades.
4. ALWAYS property support the
workpiece before beginning a cut. This will help you avoid pinching the blades
(see Fig. 3},
5. ALWAYS use steady, even pressure when making a cut, NEVER force the cut.
6. DO NOT cut wet or warped lumber.
7. ALWAYS hold the saw firmly with both hands and keep your body in a balanced
position. ALWAYS keep your body positioned to either side of the saw blades, but
not in line with the saw blades. This will help you resist the forces of kickback,
should it occur.
IMPORTANT: When using your saw, ALWAYS stay alert and exercise control.
DO NOT remove your saw from the workpiece, while the blade is moving.
11
OPERATION coni.
STARTING A CUT
IMPORTANT:
BEFORE using the Twin Cutter Saw for the first time, ALWAYS familiarize yourself
with the saw by making practice cuts in scrap materials.
The weight of this saw helps to make the cuts smoother. Learn how to safely handie
and control the weight of the saw.
ALWAYS be sure that you position the blades perpendicular to the plane of the
workpiece. Make the cut at an approximate 30° angle to the workpiece surface.
(See Fig. 5).
Practice the proper feed speed rate for the materials being cut. The blades spin at a
consistent 5500 RPM (no-load speed).
Engage the on/off switch to start the saw. To engage, press down on the back of the
switch, then push forward. ALWAYS let the blades reach full speed before you begin
the cut into the workpiece.
IMPORTANT: When using your saw, ALWAYS stay alert and exercise control.
DO NOT remove your saw from the workpiece, while the blade Is moving.
Blades perpendicular to workpiece
Approximately 30°
A WARNING: always
maintain proper control of the saw
to make sawing safer and easier.
Loss of control of the saw could
cause an accident resulting in
possible serious injury.
one hand (see Fig. 6).
always hold saw by motor body and
assist handle (see Fig. 7).
12
OPERATION coni.
TO HELP MAINTAIN CONTROL
1. ALWAYS support the workpiece near the cut.
2. ALWAYS support the workpiece so the cut wiii be on your right.
3. ALWAYS clamp the workpiece so it wiii not move during the cut.
Place the workpiece with the good side down, NOTE: The good side is the side
where appearance is important.
Before starting a cut, draw a guideline along the desired line of cut. Then piace the
front edge of the saw blades on the part of the workpiece that is solidly supported.
4. NEVER place the saw on the part of the workpiece that wiii fall off when the cut is
made.
5. ALWAYS keep the cord away from the cutting area. ALWAYS place the cord so it
does not hang up on the workpiece when making a cut.
A DANGER: If the cord hangs up on the workpiece during a cut. release the
on/off switch immediately. Unplug the saw and move the cord to prevent it from
hanging up again.
A DANGER: Using the saw with a damaged cord could result in serious
injury or death. If the cord has been damaged, have it replaced before using the
saw again.
A WARNING: If the blades come In contact with the workpiece before they
reach full speed, it could cause the saw to kickback towards you, resulting in
serious injury.
When making a cut, ALWAYS use steady, even pressure. Forcing the saw causes
rough cuts and could shorten the life of the saw or cause kickback.
A DANGER: When sawing through the workpiece, the lower blade guard
does not cover the blades.The blades are exposed on the under side of the
workpiece. ALWAYS keep your hands and fingers away from the cutting area.
Any part of your body coming in contact with the moving blades will result
in serious injury.
After completing your cut, release the on/off switch and allow the blades to come to a
complete stop. DO NOT remove the saw from the workpiece while the blades
are moving.
A CAUTION: Whenever you lift your saw from the workpiece, the blades are
exposed on the under side of the saw until the lower blade guard closes. ALWAYS
MAKE SURE that the lower blade guard is closed before setting the saw down on
work surface.
13
OPERATION coni.
CUTTING INSTRUCTIONS
NOTE: The life span of the blades on your Twin Cutter saw and the quality of the
cutting edges is dependent on keeping vibrations to a minimum.
ALWAYS securely clamp the workpiece
BEFORE beginning a cut. Then feed the
blade through the material at an angle
of approximately 30° (see Fig. 8).
This saw produces hot chips, not
sparks, when cutting metal.
It Is recommended that you wear a
face shield over safety glasses to
protect your face.
FEED SPEED
Feed speed is how quickly you push the saw blades through the material being cut.
The correct feed speed is totally determined by the hardness and the thickness of
the material being cut.
IMPORTANT: Feeding must ALWAYS be done with the blades perpendicular to the
plane of the workpiece (See Fig. A). Feeding at an angle can burn the blade and
damage the blade teeth (See Fig. B).
Selecting the correct feed speed is important.
If the feed speed Is too slow:
1. The blades will only press down on the material rather than cutting it.
2. The blade edges glide and wear down the material.
3. A poor cut will result and cause excessive wear on the blades
If the feed speed is too fast;
1. There Is a definite risk that the cut might split and the splintered opening of the cut
will not be sufficient to divert the wood shavings.
2. A poor cut will result with a significant discharge of wood shavings on the lower
side of the cut.
OPERATION cont.
CUTTING INSTRUCTIONS cont.
WHAT IT CUTS
The blades supplied with the saw are universal in application and will give clean,
smooth cuts in:
• Wood up to a maximum depth of 1 inch.
• Mild steel tubing or sheets with a maximum wall or sheet thickness of 1/16 inch.
• Copper, stainless steel, aluminum, cast Iron tubing or sheets with a wall thickness of
1/16 inch. When cutting these materials, the wax lubricating sticks MUST BE USED.
• Plastic pipe or sheets of a wall thickness of 1/16 inch.
IMPORTANT; The Twin Cutter WILL NOT CUT masonry, cement or brick material.
IMPORTANT: Once the blades become worn, chipped or dull, they MUST BE replace
immediately.
CUTTING ALL MATERIALS
1. ALWAYS have the saw blades at full speed before contacting workpiece,
2. ALWAYS hold the saw so the blades feed perpendicularly into the workpiece. Hold
the saw at an approximate 30“ angle,
3. ALWAYS keep your body positioned to either side of the saw blades, but not in line
with the saw blades.
4. Feed the blades into the workpiece until the desired cut is made.
5. The kerf (width of the cut) of the twin blades Is approximately 3/16th of an inch.
Always be sure to allow for this kerf width.
ThIsTwIn Cutter Saw with It's special blades and cutting action Is a highly
versatile tool that quickly and efficiently provides smooth, efficient cuts in a
wide variety of materials:
Corner Piece
Thin Plate Shaped Plate
Cutting other materials may require even more
special handling.These Include cutting aluminum,
copper, stainless steel and cast Iron or shaped
plates
Cutting Aluminum, Copper, Stainless Steel
and Cast Iron up to 1/16-In. thick. (See Fig. 9).
1. ALWAYS use the wax lubricating device (included)
when cutting these materials because they have a
tendency to soften and adhere to the blades.
