GENERAL SAFETY RULES  
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.  
WARNING:  
Read and understand all instructions. Failure to  
follow all instructions listed below, may result in  
electric shock, fire and/or serious personal injury.  
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.  
Do not overreach. Keep proper footing and balance  
at all times. Proper footing and balance enables better  
control of the tool in unexpected situations.  
SAVE THESE INSTRUCTIONS  
WORK AREA  
Keep your work area clean and well lit. Cluttered  
benches and dark areas invite accidents.  
Use safety equipment. Always wear eye protection.  
Dust mask, nonskid safety shoes, hard hat, or hearing  
protection must be used for appropriate conditions.  
Do not wear loose clothing or jewelry. Contain long  
hair. Loose clothes, jewelry, or long hair can be drawn  
into air vents.  
Do not use on a ladder or unstable support. Stable  
footing on a solid surface enables better control of the  
tool in unexpected situations.  
Do not operate power tools in explosive atmospheres,  
such as in the presence of flammable liquids, gases,  
or dust. Power tools create sparks which may ignite the  
dust or fumes.  
Keep bystanders, children, and visitors away while  
operating a power tool. Distractions can cause you to  
lose control.  
ELECTRICAL SAFETY  
TOOL USE AND CARE  
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.  
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.  
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.  
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.  
Disconnect the plug from power source before making  
any adjustments, changing accessories, or storing the  
tool. Such preventive safety measures reduce the risk of  
starting the tool accidentally.  
Store idle tools out of the reach of children and other  
untrained persons. Tools are dangerous in the hands of  
untrained users.  
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.  
Check for misalignment or binding of moving parts,  
breakage of parts, and any other condition that may  
affect the tool’s operation. If damaged, have the tool  
serviced before using. Many accidents are caused by  
poorly maintained tools.  
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.  
Double insulation  
eliminates the need for the three-  
wire grounded power cord and grounded power supply  
system.  
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.  
Don’t expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of elec-  
tric shock.  
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.  
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  
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.  
Keep the tool and its handle dry, clean and free from  
oil and grease. Always use a clean cloth when clean-  
ing. Never use brake fluids, gasoline, petroleum-based  
products, or any strong solvents to clean your tool. Fol-  
lowing this rule will reduce the risk of loss of control and  
deterioration of the enclosure plastic.  
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.

GENERAL SAFETY RULES  
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  
shock or injury.  
SERVICE  
Tool service must be performed only by qualified re-  
pair personnel. Service or maintenance performed by  
unqualified personnel may result in a risk of injury.  
SPECIFIC SAFETY RULES  
Always use proper guard with grinding wheel.  
A
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.  
Following this rule will reduce the risk of shock, fire, or  
serious injury.  
guard protects operator from broken wheel fragments.  
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.  
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.  
Do not abuse cord. Never carry the tool by the cord  
or yank it to disconnect it from the receptacle. Keep  
cord away from heat, oil, and sharp edges. Following  
this rule will reduce the risk of electric shock or fire.  
Know your power tool. Read operator’s manual  
carefully. Learn its applications and limitations, as  
well as the specific potential hazards related to this  
tool. Following this rule will reduce the risk of electric  
shock, fire, or serious injury.  
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. A wire gage size (A.W.G.) of at least 14  
is recommended for an extension cord 50 feet or  
less in length. A cord exceeding 100 feet is not  
recommended. If in doubt, use the next heavier  
gage. The smaller the gage number, the heavier  
the cord. An undersized cord will cause a drop in line  
voltage resulting in loss of power and overheating.  
Always wear safety glasses. Everyday eyeglasses  
have only impact-resistant lenses; they are NOT  
safety glasses. Following this rule will reduce the  
risk of serious personal injury.  
Protect your lungs. Wear a face or dust mask if the  
operation is dusty. Following this rule will reduce the  
risk of serious personal injury.  
Inspect for and remove all nails from lumber before  
using this tool. Following this rule will reduce the risk of  
serious personal injury.  
Protect your hearing. Wear hearing protection  
during extended periods of operation. Following this  
rule will reduce the risk of serious personal injury.  
Save these instructions. Refer to them frequently and  
use them to instruct others who may use this tool. If you  
loan someone this tool, loan them these instructions  
also.  
Inspect tool cords periodically and, if damaged, have  
repaired at your nearest Authorized Service Center.  
Constantly stay aware of cord location. Following this  
rule will reduce the risk of electric shock or fire.  
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  
WARNING:  
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals  
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:  
• lead from lead-based paints,  
• crystalline silica from bricks and cement and other masonry products, and  
• arsenic and chromium from chemically-treated lumber.  
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure  
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust  
masks that are specially designed to filter out microscopic particles.

ELECTRICAL  
DOUBLE INSULATION  
EXTENSION CORDS  
Double insulation is a concept in safety in electric power  
tools, which eliminates the need for the usual three-wire  
grounded power cord. All exposed metal parts are isolated  
from the internal metal motor components with protect-  
ing insulation. Double insulated tools do not need to be  
grounded.  
When using a power tool at a considerable distance from  
a power source, be sure to use an extension cord that has  
the capacity to handle the current the tool will draw. An  
undersized cord will cause a drop in line voltage, resulting in  
overheating and loss of power. Use the chart to determine  
the minimum wire size required in an extension cord. Only  
round jacketed cords listed by Underwriter’s Laboratories  
(UL) should be used.  
WARNING:  
When working outdoors with a tool, use an extension  
cord that is designed for outside use. This type of cord is  
designated with “WA” on the cord’s jacket.  
The double insulated system is intended to protect  
the user from shock resulting from a break in the  
tool’s internal wiring. Observe all normal safety  
precautions to avoid electrical shock.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.  
NOTE: Servicing of a tool with double insulation requires  
extreme care and knowledge of the system and should be  
performed only by a qualified service technician. For service,  
we suggest you return the tool to your nearest authorized  
service center for repair. Always use original factory replace-  
ment parts when servicing.

ELECTRICAL CONNECTION  
100'  
This tool has a precision-built electric motor. It should be  
connected to a power supply that is 120 volts, 60 Hz, AC  
only (normal household current). Do not operate this tool  
on direct current (DC). A substantial voltage drop will cause  
a loss of power and the motor will overheat. If the tool does  
not operate when plugged into an outlet, double-check the  
power supply.  
**Used on 12 gauge - 20 amp circuit.  
NOTE: AWG = American Wire Gauge  
WARNING:  
Keep the extension cord clear of the working area.  
Position the cord so that it will not get caught on  
lumber, tools or other obstructions while you are  
working with a power tool. Failure to do so can  
result in serious personal injury.  
WARNING:  
Check extension cords before each use. If  
damaged replace immediately. Never use tool with  
a damaged cord since touching the damaged area  
could cause electrical shock resulting in serious  
injury.

GUARD  
To operate the grinder:  
Secure all work in a vise or clamp to a workbench.  
DANGER:  
Never use the grinder with the guard removed.  
It has been designed for use only with the guard  
installed. Attempting to use grinder with guard  
removed will result in loose particles being thrown  
against the operator resulting in serious personal  
injury.  
SIDE HANDLE ON RIGHT SIDE OF GRINDER  
Fig. 7  
Hold the grinder in front and away from you with  
both hands, keeping the grinding wheel clear of the  
workpiece.  
Turn on the grinder and let the motor and grinding wheel  
build up to full speed.  
Lower the grinder gradually until the grinding wheel con-  
tacts the workpiece.  
Keep the grinder tilted at an angle from 5 to 15  
degrees.  
WARNING:  
To prevent loss of control and possible serious  
personal injury, always operate the grinder  
with both hands, keeping one hand on the side  
handle.  
Move the grinder continuously at a steady, consistent  
Fig. 8  
pace.  
NOTE: Heavy pressure will decrease the grinder’s speed and  
put a strain on the motor. Normally the weight of the tool  
alone is adequate for most grinding jobs. Use light pressure  
when grinding jagged edges or loose bolts where there is  
the potential for the grinder to snag on the metal edge.  
CAUTION:  
If the grinder is held in one spot too long, it will  
gouge and cut grooves in the workpiece. If the  
grinder is held at too sharp an angle, it will also  
gouge the workpiece because of concentration of  
pressure on a small area.  
Lift the grinder away from the workpiece before turning  
off the grinder.  
Use just enough pressure to keep the grinder from chat-  
tering or bouncing.
