IMPORTANT SAFETY INSTRUCTIONS
(For All Tools)
WARNING:
WHEN USING ELECTRIC TOOLS, BASIC SAFETY PRECAUTIONS SHOULD
ALWAYS BE FOLLOWED TO 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 manual carefully. Learn the tools
applications and limitations, as well as the
specic potential hazards peculiar to it.
2. KEEP GUARDS IN PLACE and in working
order.
3 . R E MO VE A D JU ST IN G K EY S A ND
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 . D O N ' T U S E I N D A N G E R O U S
ENVIRONMENT. Don't use power tools in
damp or wet locations, or expose them to rain.
Keep work area well lighted.
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. DON'T FORCE TOOL. It will do the job
better and safer at the rate for which it was
designed.
9. 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.
10. 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 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
resistant 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. DON'T OVERREACH. Keep proper footing
and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. 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
accessories. The use of improper accessories
may cause risk of injury to persons.
18. NEVER STAND ON TOOL. Serious injury
2
could occur if the tool is tipped or if the cutting
tool is unintentionally contacted.
19 . CHECK DAM A G ED 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, 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.
2 1 . N E V E R L E A V E T O O L R U N N I N G
UNATTENDED. TURN POWER OFF. Don't
leave tool until it comes to a complete stop.
22 . W hen s erv i ci ng use onl y ide n ti ca l
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 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 qualied
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 specied 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 tothe
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 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 gauge. The smaller the gauge number, the heavier the cord.

11. Be f o r e u s i n g t h e 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 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 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 switch off and wait for the wheel
to come to a complete stop before removing,
securing workpiece, working vise, changing
work position, angle or the wheel itself.
18. Do not touch the workpiece immediately
after operation; it is extremely hot and could
burn your skin.
