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.

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.
