BE PREPARED FOR JOB
• Wear proper apparel. Do not wear loose clothing,
gloves, neckties, rings, bracelets or other jewelry
which may get caught in moving parts of machine.
• Wear protective hair covering to contain long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses complying with United States
ANSI Z87.1. Everyday glasses have only impact
resistant lenses. They are NOT safety glasses.
• Wear face mask or dust mask if operation is dusty.
• Be alert and think clearly. Never operate power tools
when tired, intoxicated or when taking medications
that cause drowsiness.

PREPARE WORK AREA FOR JOB
• Keep work area clean. Cluttered work areas invite
accidents.
• Do not use power tools in dangerous environments.
Do not use power tools in damp or wet locations. Do
not expose power tools to rain.
• Work area should be properly lighted.
• Proper electrical receptacle should be available for
tool. Three-prong plug should be plugged directly
into properly grounded, three-prong receptacle.
• Extension cords should have a grounding prong and
the three wires of the extension cord should be of
the correct gauge.
• Keep visitors at a safe distance from work area.
• Keep children out of workplace. Make workshop
childproof. Use padlocks, master switches or remove
switch keys to prevent any unintentional use of
power tools.
TOOL SHOULD BE MAINTAINED
• Always unplug tool prior to inspection.
• Consult manual for specific maintaining and adjust-
ing procedures.
• Keep tool lubricated and clean for safest operation.
• Remove adjusting tools. Form habit of checking to
see that adjusting tools are removed before switch-
ing machine on.
• Keep all parts in working order. Check to determine
that the guard or other parts will operate properly
and perform their intended function.
• Check for damaged parts. Check for alignment of
moving parts, binding, breakage, mounting and any
other condition that may affect a tool's operation.
• A guard or other part that is damaged should be
properly repaired or replaced. Do not perform
makeshift repairs. (Use parts list provided to order
replacement parts.)
KNOW HOW TO USE TOOL
• Use right tool for job. Do not force tool or attachment
to do a job for which it was not designed.
• Disconnect tool when changing abrasive wheel.
• Avoid accidental start-up. Make sure that the tool is
in the "off" position before plugging in.
• Do not force tool. It will work most efficiently at the
rate for which it was designed.
• Keep hands away from moving parts and cutting
surfaces.
• Never leave tool running unattended. Do not leave
tool untilit comes to a complete stop.
• Do not overreach.Keep properfooting and balance.
• Never stand on tool. Serious injurycould occurif tool
is tippedor if abrasivewheel is unintentionally
contacted.
• Know your tool. Learn the tool's operation, applica-
tion and specific limitations.
• Handle workpiece correctly. Protect hands from
possible injury.
• Turn machine off if it jams. Abrasive wheel jams
when it digs too deeply into workpiece. (Motor force
keeps it stuck in the work.) Do not remove jammed
or cut off pieces until the saw is turned off,
unplugged and the wheel has stopped.
WARNING: The operation of any power tool can result
in foreign objects being thrown into the eyes, which can
result in severe eye damage.
Always wear safety goggles complying with United
States ANSI Z87.1 before commencing power tool
operation. Safety goggles are available through your
Sears catalog.
Refer to Figure 1.
Check for shipping damage. If damage has occurred, a
claim must be filed with carrier. Check for complete-
ness. Immediately report missing parts to dealer.

Hertz .................................... 60
Phase ................................ Single
ELECTRICAL CONNECTIONS
WARNING: Make sure unit is off and disconnected
from power sourcewhile motor is being mounted,con-
nected, reconnectedor any time wiring isinspected.
Cutoffsaw is assembledwith an approvedline cordto
use 115 volts.
Powersupplyto the motor is controlledby a trigger
switch,
POWER SOURCE
The motor is designed for operation on the voltageand
frequency specified.Normar loads willbe handled safe-
lyon voltages not more than 10% above or belowthe
specified voltage.
Runningthe unit on voltages which are notwithin the
range maycause overheating and motor burn-out.
Heavy loads require that the voltage at motor terminals
be no lessthan the voltage specified.
ELECTRICAL SAFETY
• Double insulated tools are equipped with a polarized
plug (one blade is wider than the other.) This plug
will fitin a polarized outlet onlyone way.If the plug
does notfit fullyin the outlet, reversethe plug. If it
stilldoes not fit, contact a qualified electrician to
install a polarized outlet.Do not change the plug in
any way.
WARNING: Do not permit fingersto touchthe termi-
nals of plugwhen installing or removing from outlet.
• Double insulation eliminates the need for the three
wire grounded power cordand grounded power sup-
ply system. Before plugging in the tool, be certain
the outlet voltage supplied is withinthe voltage
marked on the nameplate.
• Avoid body contactwith grounded surfaces such as
pipes, radiators, ranges and refrigerators.There is
an increased risk of electricshock ifyour body is
grounded. If operatingthe powertoolin damp loca-
tionsis unavoidable, a Ground Fault CircuitInterrupter
must be used to supplythe power toyour tool.
Electrician'srubber gloves andfootwear will
further enhance your personal safety.
• Don't expose powertools to rain or wet conditions.
Water entering a power tool will increasethe risk of
electric shock.
Do not abuse the cord. Never use the cordto carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electric shock.

EXTENSION CORDS
• The use of any extension cord will cause some drop
in voltageand loss of power.
• Wires of the extension cord must be of sufficientsize
to carry the currentand maintain adequate voltage.
• Use the table to determine the minimum wire size

SAFETY PRECAUTIONS
WARNING: Always observe the followingsafety pre-
cautions.
• Whenever adjustingor replacing any parts on the
cutoff saw, remove plug from powersource.
• Use a clean abrasive wheel. Replace chippedor
clogged wheels.
• Use abrasive wheels rated for saw speed
• Secure the workpieca in a stable position.
• Check that all guards are attached.
• Check t_at there isno debrison wheel or insideblade
guard.
• Keep hands away from the abrasive wheel and all
moving parts.
• Always wear eye protection or face shield.
CLAMPING WORKPIECE
Refer to Figure 3.
The vise is designed to keep the workpiece steady
while it is being cut. The proper position will help pro-
duce a safe and accurate cut.
• The entire length of long work should be supported.
Do not balance work on base. Use supports to
prevent the work from falling off after the cut.
• Vise jaw with protractor (Key No. 36) can be adjust-
ed from 0° to 45°. To change the angle of cut loosen
two socket head bolts (Key No. 45), adjust vise jaw
to desired angle and tighten socket head bolts.
• Raise lead nut (Key No. 39) off lead screw (Key No.
41). Pull lead screw out to open vise.
• Set workpiece between vise jaws. Push lead screw in
to clamp vise jaws onto workpiece. Lower lead nut to
engage lead screw. Tighten lead screw. Make sure
workpiece is securely clamped.
• Check workpiece position by lowering abrasive wheel.
CUTTING
• To cut, grip handle of housing,squeeze and main-
tain trigger. Let saw come to full speed, then press
down on handle to lower the abrasive wheel onto
workpiece.
• Do not force the tool during operation. Apply steady
but not heavy hand pressure. Heavy hand pressure
will reduce the life of the abrasive wheel.
• If the saw chatters or slows, reduce pressure. If
abrasivewheel stalls, release triggerto avoid burn-
ingout the motor.
• Note: When cutting large solid pieces (e.g. 2" dia.
round), do not overload motor -- use light to
moderate hand pressure.
• If feed pressure is too low, the abrasive wheel will
not dig into material properly.
• Do not use to cut wood or plastic materials with
abrasive wheel. Do not use to cut flammable
materials.
• Do not use cuttingfluids. This tool uses the high
RPM of its abrasive wheel to cut through metal
workpieces.
• Do not block or cover vent slots in housing; free air
flow is needed to keep the motor cool.

Refer to Figure 3.
WARNING: Make certain that the saw isdisconnected
from the powersource before attempting to service or
remove any component.
For proper maintenance:
• Keep saw clean. Sweep off spotswhere dust has
collected.
• Clean the lead screw (Key No. 41), lead nut (Key No.
39) and pivot (Key No. 40) if vise action becomes
difficult.
• Replace clogged and chippedabrasive wheels. A
clean saw with a clean abrasive wheel will yield the
best cut.
WARNING: Any attempt to repair the motor may
create a hazard unless repair is done by qualified
service technician.
If motor becomes hot or sparks are seen through the
vent slots, unscrew brush cap and check brushes
(Key Nos. 4 and 5) for wear and dirt. Clean or
