GENERAL SAFETY RULES
(For All Tools)
WARNING! Read and understand all instructions. Failure
tofollow
all instructions listed below, may result in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS.
1. Keepyour work area cleanand well lit. Clutteredbenchesand dark areas invite
accidents.
2. Do not operate powertools in explosiveatmospheres, suchas 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.
4. DoubleInsulatedtools are equippedwithapolarizedplug(onebladeiswider
than
the other.) This plug will fit in a polarizedoutlet 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 insulation eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid bodycontact with groundedsurfaces such as pipes, radiators, ranges
and refrigerators. There is an increasedrisk of electric shock if your body is
grounded.
6. Don’t expose powertools to rain or wet conditions. Water entering a power
tool
will increase the risk of electric shock.
7. Do notabuse the cord. Never usethe cord to carry the tools or pull the plug
from an outlet. Keep cord awayfrom heat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operatinga power tooloutside, usean outdoor extensioncordmarked
“W-A” or “W.” These cords are rated for outdoor use and reduce the risk
of electric shock.
9. Stayalert, watch what youare doingand usecommonsensewhenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A momentof inattentionwhile operatingpowertools
may result
in serious personal injury.
IO. Dressproperly. Donotwear looseclothing or jewelry. Containlonghair. Keep
your hair, clothing, andgloves away from movingparts. Looseclothes, jewelry
or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools withyour finger onthe switch or plugging
in tools that have the switch
on invites accidents.
12. Removeadjusting keys or switches before turning the tool on. A wrench or
a key that is left attached toa rotating part of the tool may result inpersonal
injury.
13. Do notoverreach.Keepproperfootingandbalanceatalltimes. 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.
15. Use clamps or other practical way to secure and support the workpiece to
astable platform. Holdingthe work by handor against your body is unstable
and may lead to
loss of control.
16. Do notforce tool. Usethe correct toolfor your application. The correcttool
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 plugfromthepower 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
maintainedtools, with sharp cuttingedges are less likely tobindand 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 service before using. Many accidents are causedby 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 becomehazardous
when used on another tool.
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, useonly identical replacement parts. Follow instruc-
tions
in the Maintenance section of this manual. Use of unauthorized parts
or failure tofollow Maintenance Instructions may create a risk of electric shock
of injury.

Specific Safety Rules
1. Always use properguard with grindingwheel. A guardprotects operator from
broken wheel fragments.
2. Accessories must be ratedfor at last the speed recommended on the tool
warning label. Wheels and other accessories running over rated speed can
fly apart and cause injury.
3. Holdtoolbyinsulatedgrippingsurfaceswhen performinganoperationwhere
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. Keep guards in place.
5. Useonly wheels havinga maximumoperatingspeedat leastashighas "No
LoadRPM" marked onthetool's nameplate. When using depressedcenter
wheels, be sure to use only fiberglass-reinforced wheels.
6. Check the wheel carefully for cracks or damage before operation. Replace
cracked
or damaged wheel immediately.
7. Use only flanges specified for this tool.
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. Hold the tool firmly.
IO. Keep hands away from rotating parts.
11. Make sure the wheel is not contacting the workpiece before the switch is
turned on.
12. Before using the tool onan actual workpiece, let it run for a while. Watch
for vibration or wobbling that could indicate poor installation or a poorly
balanced wheel.
13. Use the specified surface of the wheel to perform the grinding.
14. Watch outfor flying sparks. Holdthe tool so that sparks fly away fromyou

Installing wheel guard
When using a depressed center wheel or an
abrasive cut-off wheel, always use a wheel
guard. Mount the wheel guard with the tab
on the wheel guard band aligned with the
notch on the bearing box Then rotate the
wheel guard
160 degrees counterclockwise.
Be sure to tighten the screw securely.
Installing side grip (auxiliary handle)
Always install the side grip on the tool
securely before operation. The side grip can
be installed in any of three positions on the
sides of the tool, whichever is convenient
and keeps the guard properly positioned.
Always holdthe tool's switch handle andthe
side grip firmly with both hands during
operation.
,-Wheel guard
WARN I NG :
Side grip only in such a way that grinding wheel will not contact any part of your body
and that wheel guard always remains positioned as a barrier between the grinding wheel
and the operator. Failure to do
so may result in serious injury.

Operation
Holdthe tool firmly. Turn the tool on and then
apply the wheel
or disc to the workpiece.
Ingeneral, keep the edge of the wheel or disc
at an angle of about 15O to the workpiece
surface.
Duringthe break-in period with a new wheel,
do not work the grinder inthe
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
directions.

WARNING:
It should never be necessary to force the tool. The weight of the tool applies adequate
pressure. Forcing and excessive pressure could cause dangerous 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
115 mm (4-1/2") in diameter. Use of the wheel after this point is unsafe and
it should
be removed from service and rendered unusable
by intentional destruction.

MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
Replacing carbon brushes
When the resin insulating tip inside the
carbon brush is exposed to contact the
commutator,
it will automatically shut off the
motor. When this occurs, both carbon
brushes should be replaced atthe same time.
Use only identical carbon brushes.
Useascrewdriver removethe brush holder
caps. Take out the worn carbon brushes,
insert the new ones and secure the brush
holder caps.
