GENERAL SAFETY RULES
(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
READ ALL 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 atmospheres, 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 loose 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 t o install a polarized outlet. Do not change
the plug in any way. Double insulation E3 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 refrigerators. There is an increased risk of electric shock if your body is
grounded.
6. Don't expose power tools t o 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 t o 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.
IO. 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.
2
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 switches 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.
TOOL USE AND CARE
15. Use clamps or other practical way t o secure and support the workpiece t o
a stable platform. Holding the work by hand or against your body is unstable
and may lead t o 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 maintenance performed 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 unauthorized parts
or failure to follow Maintenance Instructions may create a risk of electric shock
or injury.

SPECIFIC SAFETY RULES FOR GRINDER
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. Contact with a
"live" wire will make exposed metal parts of the tool "live" and shock the
operator.
4. Never use hubbed grinding wheels on this tool (for 9523NBH only).

CAUTl ON :
Before plugging in the tool, always check to see that the switch actuates properly and
returns to the "OFF" position when the rear of the switch lever is depressed
To switch on, depress the rear of the
switch lever and push it forward. Then

Operation
Hold the tool firmly. 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" - 30" 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.

WARN I NG:
*It should never be necessary to force the tool. The weight of the tool applied adequate
pressure. Forcing and excessive pressure could cause dangerous when wheel breakage.
Continued use of a worn-out wheel may result in wheel explosion and serious personal
injury. Depressed center wheel should not be used after it has been worn down to
75 mm (3")in diameter for Model 9523NBH or 90 mm (3-1/2") for Models 9524NB and
9525NB in diameter. Use of the wheel after this point is unsafe and it should be removed
from service and rendered unusable by intentional destruction.
7
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
Replacing carbon brushes
Remove and check the carbon brushes
regularly. Replace when they wear down to
the limit mark. Keep the carbon brushes
clean and free to slip in the holders. Both
carbon brushes should be replaced at the
same time. Use only identical carbon
brushes.
-Limit
Use a screwdriver to remove the brush
holder caps. Take out the worn carbon
brushes, insert the new ones and secure
the brush holder caps.
