GENERAL SAFETY RULES
USA002-2
(For All Tools)
WARNING:
Read and understand all instructions.
Failure to follow all instructions listed
below, may result in electric shock, fire
and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control.
Electrical Safety
4. Double insulated tools are equipped with 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,
reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power supply
system.
5. Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and refrigera-
tors. There is an increased risk of electric shock if
your body is grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
7. Do not abuse the cord. Never use the cord to
carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric
shock.
8. When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce
the risk of electric shock.
Personal Safety
9. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inat-
tention while operating power tools may result in
serious personal injury.
10. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
11. Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the
switch on invites accidents.
12. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.
13. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
2
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or
hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye
protection.
Tool Use and Care
15. Use clamps or other practical way to secure and
support the workpiece to a stable platform. Hold-
ing the work by hand or against your body is unstable and may lead to loss of control.
16. Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
17. Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
18. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool
accidentally.
19. Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
20. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.
21. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged,
have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
22. Use only accessories that are recommended by
the manufacturer for your model. Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
SERVICE
23. Tool service must be performed only by qualified
repair personnel. Service or maintenance per-
formed by unqualified personnel could result in a risk
of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unau-
thorized parts or failure to follow Maintenance
instructions may create a risk of electric shock or
injury.
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 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 gage. The smaller
the gage number, the heavier the cord.

SPECIFIC SAFETY RULES
USB005-3
DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to grinder safety
rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.
1. Always use proper guard with grinding wheel. A
guard protects operator from broken wheel fragments.
2. Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels
and other accessories running over rated speed can
fly apart and cause injury.
3. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live” wire will make exposed metal parts
of the tool “live” and shock the operator.
4. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced wheels.
5. Always use safety glasses or goggles. Ordinary
eye or sun glasses are NOT safety glasses.
6. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
3
wheel immediately. Run the tool (with guard) at
no load for about a minute, holding tool away
from others. If wheel is flawed, it will likely separate during this test.
7. Use only flanges specified for this tool.
8. Be careful not to damage the spindle, the flange
(especially the installing surface) or the lock nut.
Damage to these parts could result in wheel
breakage.
9. NEVER use tool with wood cutting blades or
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of control
leading to personal injury.
10. Hold the tool firmly.
11. Keep hands away from rotating parts.
12. Make sure cord is clear of wheel. Do not wrap
cord around your arm or wrist. If control of tool
is lost, cord may become wrapped around you
and cause personal injury.
13. Make sure the wheel is not contacting the workpiece before the switch is turned on.
14. 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.
15. Use the specified surface of the wheel to perform the grinding.
16. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
17. Do not leave the tool running. Operate the tool
only when hand-held.
18. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
19. ALWAYS wear proper apparel including long
sleeve shirts, leather gloves and shop aprons to
protect skin from contact with hot grindings.
20. Use of this tool to grind or sand some products,
paints and wood could expose user to dust containing hazardous substances. Use appropriate
respiratory protection.

• NEVER bang or hit grinding disc or wheel onto
work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
• After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
Grinding and sanding operation
AB
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees 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 direction.

OPERATION
WARNIN G:
• 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.
• ALWAYS replace wheel if tool is dropped while
grinding.
CAUTION:
• Check operation of brush by running tool with no
load, insuring that no one is in front of or in line with
brush.
• Do not use brush that is damaged, or which is out
of balance. Use of damaged brush could increase
6
potential for injury from contact with broken brush
wires.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire cup brush onto spindle and tighten with supplied wrench. When using brush, avoid applying too
much pressure which causes over bending of wires,
leading to premature breakage.
Operation with wire wheel brush
(optional accessory)

CAUTION:
• Check operation of wire wheel brush by running
tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
• Do not use wire wheel brush that is damaged, or
which is out of balance. Use of damaged wire
wheel brush could increase potential for injury from
contact with broken wires.
• ALWAYS use guard with wire wheel brushes,
assuring diameter of wheel fits inside guard. Wheel
can shatter during use and guard helps to reduce
chances of personal injury.
Unplug tool and place it upside down allowing easy
access to spindle. Remove any accessories on spindle.
Thread wire wheel brush onto spindle and tighten with
