CAUTION!
The following are important notes for products, operation, and maintenance applicable to
this High-Speed Angle Grinder.
GENERAL SAFETY RULES
WORK AREA
•
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
•
Do not operate power tools in explosive atmospheres, such as in the presence
of fl ammable liquids, gases, or dust. Power tools may 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
Grounded tools must be plugged into an outlet properly installed and grounded
•
in accordance with all codes and ordinances. Never remove the grounding prong
or modify the plug in any way. Do not use any adaptor plugs. Check with a qualifi ed
electrician if you are in doubt as to whether the outlet is properly grounded. If the tools
should electrically malfunction or break down grounding provides a low resistance path
to carry electricity away from the user.
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 electric 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 infl uence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in serious personal injury.
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 or drawn into air vents.
Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
•
your fi nger on the switch or plugging in tools that have the switch on, invites accidents.
6
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. Do not use on a
ladder or unstable support.
•
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
•
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 tools sharp and clean for better and safer performance.
Follow instructions for lubricating and changing accessories. Inspect the electrical cord
periodically and if damaged, have it repaired by authorized service facility. Inspect
extension cords periodically and replace if damaged. Keep handles dry, clean and
free from oil and grease.
•
Check for damaged parts. Before using the tool each day, 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, 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. Do not use the tool if it
cannot be turned on and off by the switch.
•
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
Tool service must be performed only by qualifi ed repair personnel. Service or
•
maintenance performed by unqualifi ed personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instructions in
•
the Maintenance section of this manual. Use of unauthorized part or failure to follow
Maintenance Instructions may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES
•
Accessories must be rated for at least the speed recommended on the tool
warning label. Wheels and other accessories running over rated speed can fl y 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.
•
Know your power tool. Read operator`s manual carefully. Learn its application and
limitations, as well as the specifi c potential hazards related to this tool. Following this
rule will reduce the risk of electric shock, fi re, or serious injury.
•
Always wear safety glasses with side shields. Everyday eye-glasses have only
impact resistant lenses; they are NOT safety glasses.
•
Protect your lungs. Wear a face or dust mask if the operation is dusty.
•
Protect your hearing. Wear hearing protection during extended periods of opera-
tion.
•
Inspect tool cords periodically and if damaged, have repaired at your nearest Fac-
tory Service Center or other Authorized Service Organization. Constantly stay aware
of cord location.
•
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.
•
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.
•
Inspect for and remove all foreign objects from workpiece before polishing.
Follow this rule will reduce the risk of serious personal injury.
•
Drugs, alcohol, medication, Do not operate tool while under the infl uence of
drugs, alcohol, or any medication. Follow this rule will reduce the risk of electric
shock, fi re, or serious personal injury.
•
Keep hands away from polishing area. Follow this rule will reduce the risk of cuts,
scrapes, or serious personal injury.
•
Save these instruction. 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.
USE PROPER EXTENSION CORDS
Use only three-wire extension cords that have three-prong grounding-type plugs and
three-pole receptacles that accept the tool’s plug. Make sure your extension cord is in
good condition. Replace or repair damaged or worn cord immediately. 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
8
overheating. Below table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
