SAFETY INSTRUCTIONS
(For All Tools)
WARNING: WHEN USING ELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS BE FOLLOWEDTO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1. KNOW YOUR POWER TOOL. Read the owner's manualcarefully. Learn the
tools applications and limitations, as well as the specific potential hazards
peculiar to
it.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removedfrom tool beforeturning
it on.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. DON'T USE INDANGEROUSENVIRONMENT. Don't usepower tools in damp
or wet locations, or expose them to rain. Keep work area well lighted.
6. KEEP CHILDRENAWAY. Allvisitors should be kept safe distancefrom work

7. MAKE WORKSHOP KID PROOF with padlocks, master switches, or by
removing starter keys.
8. DON'T FORCETOOL. It will do thejob better and safer atthe ratefor which
it was designed.
9. USE RIGHT TOOL. Don't force tool or attachment to do ajob for which it
was not designed; For Example - Don't use circular saw for cutting tree
limbs
or logs.
IO. WEAR PROPER APPAREL. Wear no loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get caught in moving parts. Nonslip
footwear isrecommended. Wear protective hair coveringtocontainlong hair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting
operation isdusty. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.
12. SECUREWORK. Useclamps or a vise toholdwork when practical. It's safer
than using your hand and
it frees both hands to operate tool.
13. DON'T OVERREACH. Keep proper footing and balance at all times.

15. DISCONNECTTOOLS before servicing: when changing accessories suchas
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
recommendedaccessories. The use of improper accessories may cause risk
of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the toolistipped 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 movingparts, 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. DIRECTIONOF FEED. Feed work intoa 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. POLARIZEDPLUGS. 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 not fit, contacta qualified electriciantoinstall
the proper outlet. Do not change the plug
in any way.
VOLTAGE WARNING: Before connecting thetooltoa 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 to the 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.
3

EXTENSION CORDS. Makesure your extension cordis in goodcondition. When
using an extension cord, be sure to use one heavy enough to carry the current
your product
will draw. An undersized cord will cause a drop in line voltage
resultingin
loss of powerand overheating. Table 1 showsthe correct sizetouse
depending oncordlength andnameplate ampere rating.
If in doubt, usethe next
heavier gage. The smaller the gage number, the heavier the cord.

ADDITIONAL SAFETY RULES
1. Wear hearing protection during extended periods of operation.
2. Useonly wheels having a maximumoperating speed at least as high as "No
Load RPM" marked onthe 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 tocometoa complete stopbefore
removing, securing workpiece, working vise, changing work position, angle
or the wheel itself.
18. Do nottouch the workpiece immediately after operation; it isextremely 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 removingor installing
the wheel.
To removethe wheel, raise the safety guide. Press the shaft lock
so that the wheel cannot
revolve and use the socket wrench to loosen the hex bolt by turning it counterclockwise.
Then removethe hex bolt,outer flange and wheel. (Note:
Do not removethe innerflange,
ring and O-ring.)
To installthe wheel, follow the removalproceduresin reverse.
CAUTION:
*Be sure to tighten the hex boltsecurely. Insufficienttighteningof the hex boltmay result
insevere injury. Use the socket wrench providedto helpassure propertightening.
*Always use only the proper inner and outer flanges which are providedwith this tool.
*Always lower the safety guide after replacingthe wheel.
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.

Intervalbetween vise and guideplate
The originalspacing 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 spacingor interval.
Remove the two hex bolts which secure the guide plate. Movethe guide plate as shown
inthe figure andsecure
it usingthe hex bolts.Thefollowing interval settingsare possible:
35
- 205 mm(1-3/8" - 8-1/16")
70
- 240 mm(2-3/4" - 9-7/16")

CAUTION :
Rememberthat narrow workpieces may not be secured safely when usingthe two, wider
interval settings.
Settingfor desiredcutting angle
To change the cutting angle, loosen the
two hex boltswhich securethe guide plate.
Move the guide plate to the desired angle
(0' - 45") and tighten the hex bolts secure-
ly.
CAUTION:
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.

Securingworkpieces
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. Flip the vise nut to the rightand
then turn the vise handle clockwise to
securely retainthe workpiece.
CAUTIO
N :
Always set the vise nut to the right fully when securing the workpiece. Failure to do so
may result ininsufficientsecuring of the workpiece. This could cause the workpiece to be
ejectedor cause
a dangerousbreakage of the wheel
When the cut-off wheel has worn down
considerably, use
a spacer block of sturdy,
non-flammable material behind the work-
pieceas shown inthe figure. You can more
efficiently utilize the worn wheel by using
the mid point on the periphery
of the wheel
to cut the workpiece.
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
inthe guide plate.
Spacer block I

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
Diameter of
workpiece
Long workpieces must be supported by
blocks of non-flammable material on either
side
so that it will be level with the base
top.
Switch action
To prevent the switch trigger from being
accidentally pulled,
a lock-off button is pro-
vided as
a safety feature.
To start the tool, press in the lock-off but-
ton and pull the switch trigger. Release the
switch trigger to stop.
CAUTION:

Operation
Holdthe handle firmly.Switchonthe tool and wait untilthe wheel attains full speed before
lowering gently intothe cut.When the wheel contacts the workpiece, gradually bear down
on the handle to performthe cut. Whenthe 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 elevatedposition.
CAUTION:
Proper handle pressure during 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 tothe tool, cut-offwheel or workpiece may result.
