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.

2. CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp
or wet locations. Keep work area well lit. Don't expose power tools t o rain.
Don't use tool in presence of flammable liquids or gases.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
4.STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high
or locked-up place - out of reach of children.
5 . DON'T FORCE TOOL. It will do the job better and safer at the rate for which
it was intended.

heavy-duty tool. Don't use tool for purpose not intended.
7. DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering t o contain long hair.
8.USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9. DON'T ABUSE CORD. Never carry tool by cord or yank it t o disconnect from
receptacle. Keep cord from heat, oil. and sharp edges.
IO. SECURE WORK. Use clamps or a vise t o hold work. It's safer than using
your hand and it frees both hands to operate tool.
11. DON'T OVERREACH. Keep proper footing and balance at all times.
12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from tool before turning
it on.
15. AVOID UNINTENTIONAL STARTING. Don't carry plugged-in tool with finger
on switch. Be sure switch is OFF when plugging in.
16. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only
extension cords intended for use outdoors and so marked.
17. STAY ALERT. Watch what you are doing, use common sense. Don't operate
tool when you are tired.
18. 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, 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 by an authorized service center unless otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced by authorized service center. Don't use
tool if switch does not turn it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENT PARTS. When servicing, use only identical replacement parts.
VOLTAGE WARNING: Before connecting the tool to a 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 t o
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. Keep guards in place.
2. Use only wheels having a maximum operating speed at least as high as “No
Load RPM” marked on the tool‘s nameplate. When using depressed center
wheels, be sure t o use only fiberglass-reinforced wheels.
3. Check the wheel carefully for cracks or damage before operation. Replace
cracked or damaged wheel immediately.
4. Use only flanges specified for this tool.
5. Be careful not t o damage the spindle, the flange (especially the installing
surface) or the lock nut. Damage to these parts could result in wheel
breakage.
6. Hold the tool firmly.
7. Keep hands away from rotating parts.
8. Make sure the wheel is not contacting the workpiece before the switch is
turned on.
9. 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.
IO. Use the specified surface of the wheel to perform the grinding.
11. Watch out for flying sparks. Hold the tool so that sparks fly away from you
and other persons or flammable materials.
12. Do not leave the tool running. Operate the tool only when hand-held.

Before plugging in the tool, always check
to see that the switch actuates properly
and returns to the "OFF" position when
depressed.
Operation
Hold the tool firmly. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or
disc a t an angle of about 15' to the workpiece surface.
During the break-in period with a new
wheel, do not work the grinder in the B
direction or it will cut into the workpiece.
Once the edge of the wheel has been
rounded off by use, the wheel may be
worked in both A and B directions.
WARNING:
0 It should never be necessary to force the tool. The weight of the tool applies adequate
pressure. Forcing and excessive pressure could cause dangerous wheel breakage.
.Continued use of a worn-out wheel may result in wheel explosion and serious personal
injury. Depressed center wheel should not be used after it has been worn down to
90 mm (3-1/2") in diameter. Use of the wheel after this point is unsafe and it should be
removed from service and rendered unusable by intentional destruction.
