© Seam, Roebuck and Co.
• 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 until it comes to a complete stop.
•
Do not overreach. Keep proper footing and balance.
•
Never stand on tool. Serious injury could occur if tool
is tipped or if abrasive wheel is unintentionally
contacted.
•
Know your tool. Learn the tool's operation, application and specific limitations.
ELECTRICAL CONNECTIONS
WARNING: Make sure unit is off and disconnected
• Handle workpiece correctly. Protect hands from
possible injury.
from power source while motor is being mounted, connected, reconnected or any time wiring is inspected.
•
Cutoffsaw is assembledwith an approvedline cord to
use 115 volts.
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.
Power supply to the motor is controlledby a trigger
switch,
POWER
WARNING: The operation of any power tool can result
in foreign objects being thrown into the eyes, which can
result in severe eye damage.
SOURCE
The motor is designed for operation on the voltage and
frequency specified. Normar loads will be handled safely on voltages not more than 10% above or below the
specified voltage.
Running the unit on voltages which are not within the
range may cause overheating and motor burn-out.
Heavy loads require that the voltage at motor terminals
be no less than the voltage specified.
Always wear safety goggles complying with United
States ANSI Z87.1 before commencing power tool
operation. Safety goggles are available through your
Sears catalog.
ELECTRICAL
Refer to Figure 1.
•
Check for shipping damage. If damage has occurred, a
claim must be filed with carrier. Check for completeness. Immediately report missing parts to dealer.

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.
WARNING: Do not permit fingers to touch the terminals of plug when installing or removing from outlet.
• Double insulation eliminates the need for the three
wire grounded power cord and grounded power supply system. Before plugging in the tool, be certain
the outlet voltage supplied is within the voltage
marked on the nameplate.
• 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. If operating the power tool in damp locations is unavoidable, a Ground Fault CircuitInterrupter
must be used to supply the power to your tool.
Electrician'srubber gloves and footwear will
further enhance your personal safety.
• Don't 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 to 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
• Keep hands away from the abrasive wheel and all
moving parts.
• Always wear eye protection or face shield.
• The use of any extension cord will cause some drop
in voltage and loss of power.
• Wires of the extension cord must be of sufficient size
to carry the current and maintain adequate voltage.
• Use the table to determine the minimum wire size
(A.W.G.) extension cord.
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 produce a safe and accurate cut.
• If the extension cord is worn, cut, or damaged in any
way, replace it immediately.
• 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 adjusted 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.

SAFETY
• 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.
• 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.
PRECAUTIONS
• Do not use cutting fluids. This tool uses the high
RPM of its abrasive wheel to cut through metal
workpieces.
Always observe the followingsafety pre-
• Whenever adjusting or replacing any parts on the
cutoff saw, remove plug from power source.
• Use a clean abrasive wheel. Replace chipped or
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 is no debris on wheel or inside blade
guard.
• Do not block or cover vent slots in housing; free air
flow is needed to keep the motor cool.
