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 A re a
1.
Keep your work area clean and well lit.
Cluttered benches and dark areas invite acci­dents.
2.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Powe r
tools create sparks which may ignite the dust or fumes.
3.
Keep bystanders, children, and visitors away while operating a power tool. Distrac-
tions 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.
2
Page 3
5.
Avoid body contact with grounded sur­faces such as pipes, radiators, ranges and refrigerators. 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 inattention 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.
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. Holding 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 accidents 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 main-
tenance performed by unqualified personnel could result in a risk of injury.
3
Page 4
24.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual.
Use of unauthorized 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 bro-
ken 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. Contact with a live wire will
make exposed metal parts of the tool “live” and shock the operator.
4
4.
When using depressed center grinding wheels, be sure to use only fiberglass­reinforced 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 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.
Page 5
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.

CAUTION:
After operation, always switch off the tool and wait until the wheel has come to a complete stop before putting the tool down.
001120
Grinding and sanding operation
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.
001134
Operation with wire cup brush (optional accessory)
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 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.
