General safety precautions (For all
tools)
1. KNOW YOUR POWER TOOL. Read the owner's
manual carefully. Learn the tool's applications
and limitations, as well as the specic poten-
tial 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 keys and
adjusting wrenches are removed from tool
before turning it on.
4. KEEP WORK AREA CLEAN. Cluttered areas
and benches invite accidents.
5. DO NOT USE IN DANGEROUS ENVIRONMENT.
Do not use power tools in damp or wet loca-
tions, or expose them to rain. Keep work area
well lighted. Do not use tool in presence of
ammable liquids or gases.
6. KEEP CHILDREN AWAY. All visitors should be
kept safe distance from work area.
7. MAKE WORKSHOP KID PROOF with padlocks,
master switches, or by removing starter keys.
8. DO NOT FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.
9. USE RIGHT TOOL. Do not force tool or attach-
ment to do a job for which it was not designed.
10. WEAR PROPER APPAREL. Do not wear loose
clothing, gloves, neckties, rings, bracelets, or
other jewelry which may get caught in moving
parts. Nonslip footwear is recommended. Wear
protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use
face or dust mask if cutting operation is dusty.
Everyday eyeglasses only have impact resis-
tant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It's safer than using your
hand and it frees both hands to operate tool.
13. DO NOT OVERREACH. Keep proper footing
and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest perfor-
mance. Follow instructions for lubricating and
changing accessories.
15. DISCONNECT TOOLS before servicing; 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 acces-
sories. 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 dam-
aged 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, break-
age of parts, mounting, and any other condi-
tions 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.
3 ENGLISH
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Do not leave tool until it
comes to a complete stop.
22. REPLACEMENT PARTS. When servicing, use
only identical replacement parts.
23. POLARIZED PLUGS. To reduce the risk of elec-
tric shock, this equipment has a polarized plug
(one blade is wider than the other). This plug
will t in a polarized outlet only one way. If the
plug does not t fully in the outlet, reverse the
plug. If it still does not t, contact a qualied
electrician to install the proper outlet. Do not
change the plug in any way.
VOLTAGE WARNING: Before connecting the tool
to a power source (receptacle, outlet, etc.) be sure
the voltage supplied is the same as that specied
on the nameplate of the tool. A power source with
voltage greater than that specied 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.
USE PROPER EXTENSION CORD. 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 under-
sized cord will cause a drop in line voltage resulting
in loss of power and overheating. Table 1 shows the
correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number, the
heavier the cord.

Specic safety rules
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to portable cut-off safety rules. If you use this tool
unsafely or incorrectly, you can suffer serious per-
sonal injury.
1. Wear hearing protection during extended
period of operation.
2. Use only wheels having a maximum operat-
ing speed at least as high as "No Load RPM"
marked on the tool’s nameplate. Use only
berglass-reinforced cut-off wheels.
3. Check the wheel carefully for cracks or dam-
age before operation. Replace cracked or dam-
aged wheel immediately. Run the tool (with
guard) at no load for about a minute, holding
tool away from others. If wheel is awed, it will
likely separate during this test.
4. Secure the wheel carefully.
5. Use only anges specied for this tool.
6. Be careful not to damage the spindle, anges
(especially the installing surface) or bolt.
Damage to these parts could result in wheel
breakage.
7. Do not operate the tool without guards in
place. Check wheel guard for proper closing
before each use. Do not operate the tool if
wheel guard does not move freely and close
instantly. Never clamp or tie the wheel guard
into the open position.
8. Hold the handle rmly.
9. Keep hands away from rotating parts.
10. 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 run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
12. Watch out for ying 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 not in the path of the sparks. Keep
a proper, charged re 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 operation, makes an
odd noise or begins to vibrate, switch off the
tool immediately.
17. Turn off the tool and wait for the wheel to
stop before moving workpiece or changing
settings.
18. Do not touch the workpiece immediately after
operation; it is extremely hot and could burn
your skin.
19. Store wheels in a dry location only.
