future reference.
GEB080-3
CORDLESS DIE GRINDER
SAFETY WARNINGS
Safety Warnings Common for Grinding Operation:
1. This power tool is intended to function as a
grinder. 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.
2. Operations such as sanding, wire brushing,
polishing or cutting-off 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.
3. 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.
4. 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.
5. 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.
6. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks. 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.
7. 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.
8. 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.
9. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
10. 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.
11. 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.
12. 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.
13. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
14. 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
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

5
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.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool.
b) 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.
c) 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.
Additional safety warnings:
15. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
16. 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.
17. Use the specified surface of the wheel to
perform the grinding.
18. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
19. Do not leave the tool running. Operate the tool
only when hand-held.
20. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
21. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
22. Check that the workpiece is properly
supported.
23. 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.
24. Do not use the tool on any materials
containing asbestos.
25. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.

and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the
red indicator cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being
inserted correctly.
Battery protection system
The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes
it to draw an abnormally high current.
In this situation, turn the tool off and stop the
application that caused the tool to become
overloaded. Then turn the tool on to restart.
If the tool does not start, the battery is
overheated. In this situation, let the battery
cool before turning the tool on again.
• Low battery voltage:
The remaining battery capacity is too low
and the tool will not operate. In this situation,
remove and recharge the battery.

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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.
