KNOW YOUR POWER TOOL. Read the owner's manual carefully. Learn the
tools applications and limitations, as well as the specific potential hazards
peculiar to it.
KEEP GUARDS IN PLACE and in working order.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removedfrom tool before turning
it on.
KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
DON'T USE INDANGEROUSENVIRONMENT. Don't use power tools
in damp
or wet locations, or expose them to rain. Keep work area well lighted.
KEEP CHILDREN AWAY. All visitors should bekept safe distance from work
area.
MAKE WORKSHOP KID PROOF
with padlocks, master switches, or by
removing starter keys.
DON'T FORCETOOL.
It willdo thejob better and safer at the rate for which
it was designed.
USE RIGHT TOOL. Don't force
tool or attachment to do a job for which it
was not designed; For Example - Don't use circular saw for cutting tree
limbs or logs.
WEAR PROPER APPAREL. Wear no loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get caught
in moving parts. Nonslip
footwear is recommended. Wear protective hair covering tocontainlonghair.
ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting
operation is dusty. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.
SECUREWORK. Use clamps or a vise to holdwork when practical. It's safer
than using your hand and
it frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and
safest performance. Follow instructionsfor lubricating and changing acces-
sories.

15. DISCONNECT TOOLS beforeservicing; when changing accessories such as
blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is
in off position before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for
recommended accessories. The use of improper accessories may cause risk
of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or
if the cutting tool is unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that it will
operate properly and perform its intended function
- check for alignment
of movingparts, binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced.
20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction
of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't
leave tool
until it comes to a complete stop.
22. When servicing use only identical replacement parts.
23. POLARIZED PLUGS.To reduce the risk of electric shock, this equipment has
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,
reversethe plug. If
it stilldoes notfit, contact aqualified electrician toinstall
the proper outlet. Do not change the plug
in any way.
VOLTAGE WARNING: Before connectingthe tool toa power source (receptacle.
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source
with voltage greater than that specified
for the tool can result in SERIOUS INJURY tothe user
- as well as damage to
the tool. If
in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES
1. Wear hearing protection during extended periods of operation.
2. Use only wheels havinga maximumoperating speed at least as highas "No
Load RPM" marked on the tool's nameplate. Use only fiberglass-reinforced
cut-off wheels.
3. Check the wheel carefully for cracks or damage before operation. Replace
cracked or damaged wheel immediately.
4. Secure the wheel carefully.
5. Use only flanges specified for this tool.
6. Be careful not to damage the spindle, flanges (especially the installing
7. Keep guards in place and in working order.
8. Hold the handle firmly.
9. Keep hands away from rotating parts.
surface) or bolt, or the wheel itself
might break.
IO. Make sure the wheel is not contacting the workpiece before the switch is
turned on.
11. Before using the tool on an actual workpiece, let it simply run for several
minutes first. Watch for flutter or excessive vibration that might be caused
by poor installation or a poorly balanced wheel.
12. Watch out for flying sparks when operating. They can cause injury or ignite
combustible materials.
13. Remove material or debris from the area that might be ignited by sparks.
Be sure that others are notinthe pathof the sparks. Keep a proper, charged
fire extinguisher closely available.
14. Use the cutting edge of the wheel only. Never use side surface.
15. Do not attempt to keep the trigger in the ON position.
16. If the wheel stops during the operation, makes an odd noise or begins to
vibrate, switch off the tool immediately.
17. Always switchoff and wait for the wheel tocome to a complete stop before
removing, securingworkpiece, working vise, changing work position, angle
or the wheel itself.
18. Do nottouch the workpiece immediately after operation; it is extremely hot
and could burn your skin.
19. Store wheels in a dry location only.
SAVE THESE INSTRUCTIONS.

Securing cut-off
The cut-off may be bolted (2 bolts)down to
a level location using the bolt holes in the
base.
Removing or installingcut-off wheel
CAUTION:
Always be sure that the
tool is switched off and unpluggedbefore removing or installing
the wheel.
To remove the wheel, raisethe safety guide. Pressthe shaft lock
so that thewheel cannot
revolve and use the socket wrench
to loosen the hex bolt by turning it counterclockwise.
Then remove the hex bolt, outer flange and wheel. (Note: Do not remove the inner flange,
ringand O-ring.)
To install the wheel, follow the removal procedures inreverse.
CAUTION:
*Be sure to tighten the hex boltsecurely. Insufficient tightening of the hex bolt may result
in severe injury. Use the socket wrench provided to help assure proper tightening.
*Always useonly the proper inner and outer flanges which are provided with this tool.
*Always lower the safety guide after replacingthewheel

Spark guard
The spark guard is factory-installed with its
lower edge contacting the base. Operating
the
tool in this position will cause may
sparks to fly around. Loosen the screw and
adjust the spark guard
to a position at
which minimum sparks will fly around.

Stopper plate
The stopper plate prevents the wheel from
contacting the workbench
or floor surface.
When
a new wheel is installed, set the
stopper plate to the position
(A). When the
wheel wears down to below 330
mm (1 3”)
in diameter, set the stopper plate to the
position
(B) to allow an increased cutting
capacitywith the worn downwheel.
I I
Interval betweenvise and guide plate
The original spacing or interval between the vise and the guide plate is 0 - 170 mm (0 -
6-11/16”). If your work requires wider spacing or interval, proceed as follows to change
the spacing or interval.
Remove the two hex boltswhich secure the guide plate. Move the guide plate as shown
in the figure and secure
it using the hex bolts. The following interval settings are possible:
35
- 205 mm(1-3/8” - 8-1/16”)
70
- 240 mm(2-3/4” - 9-7/16”)

To change the cutting angle, loosen the
two hex bolts which secure the guide
plate. Move the guide plate to the desired
angle (0" - 45") and tighten the hex bolts
securely.
CAUTION:
/ f?l Socket wrench
Never perform miter cuts when the guide plate is set at the 35 - 205 mm (1-3/8" -
8-1/16") or 70 - 240 mm(2-3/4" - 9-7/16") position
Securing workpieces
By turning the vise handle counterclock-
wise and then flipping the vise nut to the
left, the vise is released from the shaft
threads and can be moved rapidly in and
out. To grip workpieces, push the vise
handle until the vise plate contacts the
workpiece. Flipthe vise nut tothe right and
then turn the vise handle clockwise to
securely retain the workpiece.
CAUTION:
Always set the vise nut to the right
fully when securing the workpiece. Failure to do so
may result in insufficient securing of the workpiece. This could cause the workpiece to be
ejected or cause a dangerous breakage of thewheel.
When the cut-off wheel has worn down
considerably, use
a spacer block of sturdy,
non-flammable material behind the work-
piece as shown inthe figure. You can more
efficiently utilize the worn wheel by using
the mid pointon the periphery of the wheel
to cut the workpiece.
8

When cutting workpieces over 65 mm
(2-9/16") wide at an angle, attach a straight
piece
of wood (spacer) over 190 mm
(7-1/2") long x 45 mm (1-3/4") wide to the
guide plate as shown in the figure. Attach
this spacer with screws through the holes
in the guide plate.
If you use a spacer block which is slightly
narrower than the workpiece as shown
in
the figure, you can also utilize the wheel
economically.
Long workpieces must be supported by
blocks
of non-flammable material on either
side so that it will be level with the base
top.

Operation
Holdthe handlefirmly. Switch on the tool and wait untilthe wheel attains full speed before
lowering gently into the cut. When the wheel contacts the workpiece, gradually bear down
on the handle to perform the cut. When the cut is completed, switch off the
tool and WAIT
UNTIL THE WHEEL HAS COME TO A COMPLETE STOP before returning the handle to
the fully elevated position.
CAUTION:
Proper handle pressureduring cutting and maximum cutting efficiency can be determined
by the amount of sparks that is produced while cutting. Your pressure on the handle
should be adjusted to produce the maximum amount
of sparks. Do not force the cut by
applying excessive pressure on the handle. Reducedcutting efficiency, premature wheel
wear, as well as, possibledamage to the tool, cut-off wheel or workpiece may result.
