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 instructions for lubricating andchanging acces-
sories.

15. DISCONNECT TOOLS before servicing; when changing accessoriessuch as
blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONALSTARTING. 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 accessoriesmay causerisk
of injury to persons.
18. NEVER STAND ON TOOL. Serious injury could occur if the tool istipped 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 moving parts, binding of moving parts, breakageof 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. Feedwork into a blade or cutteragainst 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 reducethe risk of electric shock, this equip-
ment hasa polarized plug (one blade is wider thanthe other). This plug
will fit
in a polarizedoutlet only oneway. Ifthe plug does not fit fully in
the outlet, reversethe plug. If it still does not fit, contacta qualified
electrician
to installthe proper outlet. Do not changethe plug in any
way.
VOLTAGEWARNING: Beforeconnecting 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 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.

EXTENSION CORDS. Make sure your extension cord is in good condition.
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 voltageresulting in loss of powerand overheating. Table 1 shows the
correct size tousedependingon cord lengthand nameplateampere rating.
If in doubt, use the next heavier gauge. The smaller the gauge number, the
heavier the
cord.

ADDITIONAL SAFETY RULES
1. Wear hearing protection during extended periods of operation.
2. Useonly wheels havingamaximumoperating speed atleast as highas "No
Load
RPM" markedonthe 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

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
minutesfirst. 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 injuryor ignite
combustible materials.
13. Remove material or debris from the area that might be ignited by sparks.
Be surethat othersare not in the 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 wheeltocometoacomplete stop before
removing, securingworkpiece, working vise, changing work position, angle
or the wheel itself.
18. Do nottouchthe workpiece immediately after operation; it isextremely hot
and could burn your skin.
19. Store wheels in a dry location only.

CAUTION :
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 counterclockwise
and then flipping the vise nuttothe 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 right and then turn the vise
handle clockwise to securely retain the
workpiece.
When the cut-off wheel has worn down
considerably, use
a spacer block of sturdy,
non-flammable material behind the work-
piece as shown in the figure.
You can more
efficiently utilizethe worn wheelby usingthe
mid point on the periphery of the wheel to
cut the workpiece.

prevents unauthorized operation.
Operation
Holdthe handlefirmly. Switch on the tool and wait untilthe wheel attains full speed before
lowering gently into the cut. When the wheelcontacts the workpiece,graduallybear down
on the handleto performthe cut. When
the cut iscompleted, switch off thetool and WAIT
UNTILTHE WHEEL HASCOMETO A COMPLETESTOP before returning the handleto the
fully elevated position.
CAUTIO
N:
Proper handlepressure during cutting and maximum cutting efficiency can be determined
by the amount of sparks that is producedwhile cutting. Your pressureon the handleshould
be adjustedto producethe maximum amount of sparks.
Do not force the cut by applying
excessive pressureon the handle. Reduced cutting efficiency, premature wheel wear, as
well as, possible damage to the tool, cut-off wheel or workpiece may result.
