SAFETY WARNINGS
General power tool safety warnings
WARNING Read all safety warnings, instruc-
tions, illustrations and specications provided with
this power tool. Failure to follow all instructions listed
below may result in electric shock, re and/or serious
injury.
Save all warnings and instruc-
tions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Grinder safety warnings
Safety warnings common for grinding, sanding,
wire brushing, or cutting-o󰀨 operations:
1. This power tool is intended to function as a
grinder, sander, wire brush, hole cutter or cut-
o󰀨 tool. Read all safety warnings, instructions,
illustrations and specications provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, re and/
or serious injury.

10 ENGLISH
2. Operations such as polishing are not to be
performed with this power tool. Operations for
which the power tool was not designed may create
a hazard and cause personal injury.
3. Do not convert this power tool to operate in
a way which is not specically designed and
specied by the tool manufacturer. Such a con-
version may result in a loss of control and cause
serious personal injury.
4. Do not use accessories which are not spe-
cically designed and specied by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
5. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and y apart.
6. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
7. The dimensions of the accessory mounting
must t the dimensions of the mounting hard-
ware of the power tool. Accessories that do not
match the mounting hardware of the power tool
will run out of balance, vibrate excessively and
may cause loss of control.
8. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged acces-
sories will normally break apart during this test
time.
9. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
ying debris generated by various applications.
The dust mask or respirator must be capable
of ltrating particles generated by the particular
application. Prolonged exposure to high intensity
noise may cause hearing loss.
10. Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may y away and cause injury beyond immediate
area of operation.
11. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
12. Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
13. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
14. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
15. Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
16. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
17. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and related warnings:
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite
of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that is
entering into the pinch point can dig into the surface of
the material causing the wheel to climb out or kick out.
The wheel may either jump toward or away from the
operator, depending on direction of the wheel’s move-
ment at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
1. Maintain a rm grip with both hands on the
power tool and position your body and arms
to allow you to resist kickback forces. Always
use auxiliary handle, if provided, for maxi-
mum control over kickback or torque reaction
during start-up. The operator can control torque
reactions or kickback forces, if proper precautions
are taken.
2. Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
3. Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
4. Use special care when working corners, sharp
edges, etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
5. Do not attach a saw chain woodcarving blade,
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.
Such blades create frequent kickback and loss of
control.

11 ENGLISH
Safety warnings specic for grinding and cutting-o󰀨
operations:
1. Use only wheel types that are specied
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
2. The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
3. The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
4.
Wheels must be used only for specied applica-
tions. For example: do not grind with the side of
cut-o󰀨 wheel. Abrasive cut-o󰀨 wheels are intended
for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
5. Always use undamaged wheel anges that are
of correct size and shape for your selected
wheel. Proper wheel anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-o󰀨 wheels may be di󰀨erent from
grinding wheel anges.
6. Do not use worn down wheels from larger
power tools. A wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
7. When using dual purpose wheels always use
the correct guard for the application being
performed. Failure to use the correct guard may
not provide the desired level of guarding, which
could lead to serious injury.
Additional safety warnings specic for cutting-o󰀨
operations:
1. Do not “jam” the cut-o󰀨 wheel or apply exces-
sive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibil-
ity of kickback or wheel breakage.
2. Do not position your body in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
3. When the wheel is binding or when interrupt-
ing a cut for any reason, switch o󰀨 the power
tool and hold it motionless until the wheel
comes to a complete stop. Never attempt to
remove the cut-o󰀨 wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
4. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
5. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel.
6. Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
7. Do not attempt to do curved cutting.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel
in the cut and the possibility of kickback or wheel
breakage, which can lead to serious injury.
8. Before using a segmented diamond wheel,
make sure that the diamond wheel has the
peripheral gap between segments of 10 mm or
less, only with a negative rake angle.
Safety warnings specic for sanding operations:
1. Use proper sized sanding disc paper. Follow
manufacturers recommendations, when
selecting sanding paper. Larger sanding paper
extending too far beyond the sanding pad pres-
ents a laceration hazard and may cause snagging,
tearing of the disc or kickback.
Safety warnings specic for wire brushing
operations:
1. Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
2. If the use of a guard is specied for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional Safety Warnings:
1. When using depressed centre grinding wheels,
be sure to use only berglass-reinforced
wheels.
2. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
3. Be careful not to damage the spindle, the
ange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
4. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
5. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
6. Use the specied surface of the wheel to per-
form the grinding.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.

12 ENGLISH
9. Do not touch accessories immediately after
operation; it may be extremely hot and could
burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
11. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
12. Use only anges specied for this tool.
13. For tools intended to be tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
14. Check that the workpiece is properly
supported.
15. Pay attention that the wheel continues to
rotate after the tool is switched o󰀨.
16. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
17. Do not use the tool on any materials contain-
ing asbestos.
18. When use cut-o󰀨 wheel, always work with
the dust collecting wheel guard if required by
domestic regulation.
19. Cutting discs must not be subjected to any
lateral pressure.
20. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
21. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the workpiece. Otherwise, it may
cause an electric shock, electrical leakage or gas
leak.
22. If a blotter is attached to the wheel, do not
remove it. The diameter of the blotter must be
larger than the lock nut, outer ange, and inner
ange.
23. Before installing a grinding wheel, always
check that the blotter part does not have any
abnormalities such as chips or cracks.
24. Tighten the lock nut properly. Overtightening
the wheel can cause breakage and insu󰀩cient
tightening can cause uttering.

attachment will damage the tool.
OPERATION
WARNING: It should never be necessary to
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER hit the workpiece with the
wheel.
WARNING: Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING: NEVER use tool with wood cutting
blades and other saw blades. Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
CAUTION: Never switch on the tool when it
is in contact with the workpiece, it may cause an
injury to operator.
CAUTION: Always wear safety goggles or a
face shield during operation.
CAUTION: After operation, always switch o󰀨
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool rmly with
one hand on housing and the other on the side
grip (handle).
NOTE: A dual purpose wheel can be used for both
grinding and cutting-o󰀨 operations.
Refer to the "Grinding and sanding operation" for
grinding operation, and refer to the "Operation with
abrasive cut-o󰀨 / diamond wheel" for cutting-o󰀨
operation.
Grinding and sanding operation
► Fig.28
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° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded o󰀨 by use, the wheel may be worked in both
forward and backward direction.
Usage example: operation with cup-type diamond
wheel
► Fig.29
Keep the tool horizontally and apply the entire cup-type
diamond wheel to the workpiece surface.
Operation with abrasive cut-o󰀨 /
diamond wheel
Optional accessory
WARNING: Do not "jam" the wheel or apply
excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility
of kickback, wheel breakage and overheating of the
motor may occur.
WARNING: Do not start the cutting operation
in the workpiece. Let the wheel reach full speed
and carefully enter into the cut moving the tool
forward over the workpiece surface. The wheel
may bind, walk up or kickback if the power tool is
started in the workpiece.
WARNING: During cutting operations, never
change the angle of the wheel. Placing side pres-
sure on the cut-o󰀨 wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING: A diamond wheel shall be oper-
ated perpendicular to the material being cut.
For model GA7080 / GA9080, you can rotate the switch
handle.

COMBINATION OF APPLICATIONS AND
ACCESSORIES
Optional accessory
CAUTION: Using the tool with incorrect guards can cause risks as follows.
•When using a cut-o󰀨 wheel guard for facial grinding, the wheel guard may interfere with the work-
piece causing poor control.
•When using a grinding wheel guard for cutting-o󰀨 operations with bonded abrasive wheels and dia-
mond wheels, there is an increased risk of exposure to rotating wheels, emitted sparks and particles,
as well as exposure to wheel fragments in the event of wheel burst.
•When using a cut-o󰀨 wheel guard or grinding wheel guard for facial operations with cup-type dia-
mond wheels, the wheel guard may interfere with the workpiece causing poor control.
•When using a cut-o󰀨 wheel guard or grinding wheel guard with a wheel-type wire brush with a thick-
ness greater than the maximum thickness as specied in "SPECIFICATIONS", the wires may catch on
the guard leading to breaking of wires.
•Use of dust collecting wheel guards for cutting-o󰀨 and facial operations in concrete or masonry
reduces a risk of exposure to dust.
•When using dual purpose (combined grinding and cutting-o󰀨 abrasive) ange mounted wheels, only
use a cut-o󰀨 wheel guard.
