The tool is intended for grinding, sanding and cutting of
metal and stone materials without the use of water.
SPECIFIC SAFETY RULES
GEB033-1
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to grinder
safety rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.
1. Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-Off
Operations:
2. This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool. Read all
safety warnings, instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.
3. Operations such as polishing are not
recommended to be performed with this power
tool. Operations for which the power tool was not
designed may create a hazard and cause personal
injury.
4. Do not use accessories which are not specifically
designed and recommended 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 fly 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 arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the
spindle of the power tool. Accessories with arbour
holes 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 accessory 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 accessories 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 appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various
operations. The dust mask or respirator must be
capable of filtrating particles generated by your
operation. 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 fly away and
cause injury beyond immediate area of operation.
11. Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring or its
own cord. Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool “live”
and shock the operator.
12. Position the cord clear of the spinning accessory.
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 accessory
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 flammable
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.
18. Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or any
other accessory. Pinching or snagging causes rapid
stalling of the rotating accessory which in turn causes
the uncontrolled 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
movement 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.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start-up. The operator can
control torque reactions or kickback forces, if proper
precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your hand.
c) 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.
d) 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.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
19. Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
a) Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded
and are unsafe.
b) 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 operator from
broken wheel fragments and accidental contact with
wheel.
c) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
d) Always use undamaged wheel flanges that are
of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
e) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool is
not suitable for the higher speed of a smaller tool and
may burst.
20. Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
a) Do not “jam” the cut-off 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 or wheel breakage.
b) 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 spinning wheel and
the power tool directly at you.
c) When wheel is binding or when interrupting a
cut for any reason, switch off the power tool and
hold the power tool motionless until the wheel
comes to a complete stop. Never attempt to
remove the cut-off 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.
6
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the
workpiece.
e) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
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.
f) Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
21. Safety Warnings Specific for Sanding Operations:
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc or kickback.
22. Safety Warnings Specific for Wire Brushing
Operations:
a) 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.
b) If the use of a guard is recommended for wire
brushing, do not allow 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.
23. When using depressed center grinding wheels, be
sure to use only fiberglass-reinforced wheels.
24. 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.
25. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
26. 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.
27. Use the specified surface of the wheel to perform
the grinding.
28. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
29. Do not leave the tool running. Operate the tool
only when hand-held.
30. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.
31. Always be sure that the tool is switched off and
unplugged or that the battery cartridge is removed
before carrying out any work on the tool.
32. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
33. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
34. Use only flanges specified for this tool.
35. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
36. Check that the workpiece is properly supported.
37. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
38. Pay attention that the wheel continues to rotate
after the tool is switched off.
39. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
40. Do not use the tool on any materials containing
asbestos.
41. Do not use water or grinding lubricant.
42. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
43. When use cut-off wheel, always work with the dust
collecting wheel guard required by domestic
regulation.
44. Cutting discs must not be subjected to any lateral
pressure.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.

FUNCTIONAL DESCRIPTION
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
(Fig. 1)
Always switch off the tool before insertion or removal of
the battery cartridge.
To remove the battery cartridge, withdraw it from the
tool while sliding the button on the front of the cartridge.
To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.
Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.

Indication lamp with multi function
(Fig. 4)
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with the
slide switch positioned in the “O (OFF)” position, the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication
lamp has broken.
- Overload protection
- When the tool is overloaded, the indication lamp lights
up. When the load on the tool is reduced, the lamp
goes out.
- If the tool continues to be overloaded and the
indication lamp continues to light up for approximately
two seconds, the tool stops. This prevents the motor
and its related parts from being damaged.
- In this case, to start the tool again, move the slide
switch to the “O (OFF)” position once and then to the “I
(ON)” position.
- Battery cartridge replacing signal
- When the remaining battery capacity gets small, the
indicator lamp lights up during operation earlier than
enough capacity battery use.
- Accidental re-start preventive function
- Even if the battery cartridge is inserted on the tool with
the slide switch in the “I (ON)” position, the tool does
not start. At this time, the lamp flickers slowly and this
shows that the accidental re-start preventive function
is at work.
- To start the tool, first slide the slide switch toward the
“O (OFF)” position and then slide it toward the “I (ON)”
position.

CAUTION:
Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.
Mount the inner flange onto the spindle. Fit the diamond
wheel on over the inner flange and screw the lock nut onto
the spindle. Notice that flat side of the lock nut should face
the diamond wheel in case the diamond wheel is used.
WARNING:
Only actuate the shaft lock when the spindle is not
moving.
OPERATION
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.
ALWAYS replace wheel if tool is dropped while
grinding.
NEVER bang or hit grinding disc or wheel onto work.
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
Make the depth of a single cut up to 5 mm. Adjust
pressure on the tool so that the tool does not slow
down during the operation.
After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
Grinding and sanding operation (Fig. 10)
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. 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 degrees
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.
Operation with diamond wheel
(accessory)
WARNING:
Forcing and exerting excessive pressure or allowing
the wheel to bend, pinch or twist in the cut can cause
overheating of the motor and dangerous kickback of
the tool.
CAUTION:
After cutting operation, make sure that the diamond
wheel stops revolving completely. Then, place the tool.
It is dangerous to place the tool before turning off the
tool. If there are dust or dirt around the tool, the tool
may suck in them.
Be sure that the wheel does not contact the workpiece.
Turn the tool on and hold the tool firmly. Wait until the
wheel attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it flat and
advancing smoothly until the cutting is completed.

diamantée sur le flasque intérieur et vissez le contre-
écrou sur l'axe. Notez que le côté plat du contre-écrou
doit faire face à la meule diamantée si la meule
diamantée est utilisée.
AVERTISSEMENT :
N'activez le blocage de l'arbre que lorsque l'axe ne
bouge pas.
UTILISATION
AVERTISSEMENT :
Il n'est jamais nécessaire de forcer l'outil. Le poids de
l'outil lui-même suffit à assurer une pression adéquate.
En forçant l'outil ou en appliquant une pression
excessive dessus vous courrez le risque dangereux de
casser la meule.
Remplacez TOUJOURS la meule si l’outil vous
échappe pendant le meulage.
Ne frappez JAMAIS le disque de meulage ou la meule
contre la pièce à travailler.
Évitez de laisser la meule sautiller ou accrocher, tout
spécialement lorsque vous travaillez dans les coins,
sur les bords tranchants, etc. Cela peut causer une
perte de contrôle et un choc en retour.
N'utilisez JAMAIS cet outil avec des lames à bois et
autres lames de scie. Les lames de ce type sautent
fréquemment lorsqu'elles sont utilisées sur une
meuleuse et risquent d'entraîner une perte de contrôle
pouvant causer des blessures.
ATTENTION :
La profondeur maximale d'une coupe simple est de 5
mm. Ajustez votre pression sur l'outil de sorte qu'il ne
ralentisse pas pendant l'utilisation.
Après l'utilisation, mettez toujours l'outil hors tension et
attendez l'arrêt complet de la meule avant de déposer
l'outil.
Si l'outil a fonctionné de façon continue jusqu'à ce que
la batterie soit épuisée, laissez-le reposer pendant 15
minutes avant de recommencer avec une batterie
fraîche.
Meulage et ponçage (Fig. 10)
Tenez TOUJOURS l'outil fermement en posant une main
sur le carter et l'autre main sur le manche latéral. Mettez
l'outil en marche puis posez la meule ou le disque sur la
pièce à travailler.
En général, vous devez maintenir le bord du disque ou de
la meule sur un angle d'environ 15 degrés
par rapport à la surface de la pièce à travailler.
Pendant la période de rodage d'une meule neuve, ne
faites pas avancer la meuleuse dans le sens B, sinon elle
risque de couper la pièce à travailler. Une fois le tranchant
de la meule rodé, la meule peut être utilisée dans les sens
A et B.
Utilisation avec une meule diamantée
(accessoire)
AVERTISSEMENT :
Si vous forcez la meule, lui appliquez une pression
excessive ou la laissez se plier, se coincer ou se tordre
dans la ligne de coupe, vous risquez de faire
surchauffer le moteur ou de provoquer un choc en
retour.
ATTENTION :
Après la coupe, assurez-vous que la meule diamantée
a complètement cessé de tourner. Déposez ensuite
l'outil. Il es dangereux de déposer l'outil avant d'arrêter
l'outil. S'il y a des poussières ou saletés autour de
l'outil, ce dernier risque de les aspirer.
Assurez-vous que le meule n'entre pas en contact avec la
pièce à travailler. Mettez l'outil en marche et tenez-le
fermement. Attendez que la meule ait atteint sa pleine
vitesse. Ensuite, déplacez simplement l'outil vers l'avant
sur la surface de la pièce, en le maintenant bien à plat et
en le faisant avancer doucement, jusqu'à ce que la coupe
soit terminée.
MAINTENANCE
ATTENTION :
Assurez-vous toujours que l'outil est hors tension et
que la batterie est retirée avant d'y effectuer tout travail
d'inspection ou d'entretien.
L'outil et ses orifices d'aération doivent être maintenus
propres. Nettoyez les orifices d'aération de l'outil
régulièrement ou chaque fois qu'ils commencent à se
boucher. (Fig. 11)
Remplacement des charbons
Retirez et vérifiez les charbons régulièrement.
Remplacez-les lorsqu'ils atteignent la marque de limite.
Gardez les charbons propres et libres de glisser dans les
porte-charbons. Il faut remplacer les deux charbons en
même temps. Utilisez uniquement des charbons
identiques. (Fig. 12)
Insérez le bout d'un tournevis à tête fendue dans l'entaille
de l'outil et retirez le cache du bouchon de porte-charbon
en le soulevant. (Fig. 13)
Retirez les bouchons de porte-charbon à l'aide d'un
tournevis. Enlevez les charbons usés, insérez les neufs et
remettez en place les bouchons de porte-charbon.
(Fig. 14)
Remettez le cache de bouchon de porte-charbon en place
sur l'outil.
Pour assurer la SÉCURITÉ et la FIABILITÉ du produit,
toute réparation et tout travail d'entretien ou de réglage
doivent être effectués par un Centre de service après-
vente agréé Makita, avec des pièces de rechange Makita.
