i) 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.
j) 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.
k) 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.
l) 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.
m) 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.
n) Regularly clean the power tool’s air vents.

the housing and excessive accumulation of
powdered metal may cause electrical hazards.
o) Do not operate the power tool near
flammable materials.
Sparks could ignite these materials.
p) 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 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 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)Wheels must be used only for
recommended applications. For example:
do not grind with the side of cut-offwheel.
Abrasive cut-offwheels are intended for
peripheral grinding, side forces applied to these
wheels may cause them to shatter.
c) Always use undamaged wheel flanges
that are of correct size and shape for your
selected wheel.
000BookGP10DLUS.indb6000BookGP10DLUS.indb6 2010/12/0617:39:292010/12/0617:39:29

English
Proper wheel flanges support the wheel thus
reducing the possibility of wheel breakage.
Flanges for cut-offwheels may be different from
grinding wheel flanges.
d) 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.
GENERAL SAFETY
INSTRUCTIONS FOR GRINDERS
– Check that speed marked on the wheel is
equal to or greater than the rated speed of the
grinder;
– Ensure that the wheel dimensions are
compatible with the grinder;
– Abrasive wheels shall be stored and handled
with care in accordance with manufacturer’s
instructions;
– Inspect the grinding wheel before use, do not
use chipped, cracked or otherwise defective

or if other defects are detected. If this condition
occurs, check the machine to determine the
cause;
– If a guard is equipped with the tool never use
the tool without such a guard;
– Do not use separate reducing bushings or
adapters to adapt large hole abrasive wheels;
– 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;
– Check that the work piece is properly
supported;
– Do not use cutting offwheel for side grinding;
– Ensure that sparks resulting from use do not
create a hazard e.g. do not hit persons, or ignite
flammable substances;
– 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;
– Always use eye and ear protection. Other
personal protective equipment such as dust
mask, gloves, helmet and apron should be
worn;
– Pay attention to the wheel that continues to
rotate after the tool is switched off.

How to make the batteries perform longer
○Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool
becomes weaker, stop using the tool and
recharge its battery. If you continue to use the
tool and exhaust the electric current, the battery
may be damaged and its life will become
shorter.
○Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately
after use. If such a battery is recharged
immediately after use, its internal chemical
substance will deteriorate, and the battery
life will be shortened. Leave the battery and
recharge it after it has cooled for a while.
CAUTION
●When the battery charger has been
continuously used, the battery charger will
be heated, thus constituting the cause of
the failures. Once the charging has been
completed, give 15 minutes rest until the
next charging.
●If the battery is charged while it is heated
because it has been left for a long time
in a location subject to direct sunlight or
because the battery has just been used,
the pilot lamp of the charger lights for 1
second, does not light for 0.5 seconds (off
for 0.5 seconds). In such a case, first let
the battery cool, then start charging.
●When the pilot lamp flickers (at 0.2-second
intervals), check for and take out any
foreign objects in the charger’s battery
installation hole. If there are no foreign
objects, it is probable that the battery or
charger is malfunctioning. Take it to your
authorized Service Center.
●If the battery charger does not work while
the battery is mounted correctly, it is
probable that the battery or charger is
malfunctioning. Take it to your authorized
Service Center.
BEFORE USE
Check the work area to make sure that it is clear of
debris and clutter.
Clear the area of unnecessary personnel. Ensure
that lighting and ventilation is adequate.

OPERATING THE GRINDER
WARNING
●Keep your face away from the tip tool
during use.
●Wear goggles and a dust mask when using
the grinder. Breakage of the tip tool may
lead to injury.
●Do not operate the grinder at extremely
slow speed. A smooth finished surface will
not be achieved and doing so may lead to
damage of the tip tool, breakdown of the
grinder or injury.
CAUTION
Do not touch the tip tool, collet nut or collet
immediately after machining as they will be
very hot and touching them may result in
burns.
1. Remove the battery and attach the tip tool
2. Fix the workpiece so that it does not move
The smaller the workpiece, the more unstable it
is to machine. Fix small workpieces in a vise.
Holding the workpiece by hand may result in
injury.
3. Insert the battery in the grinder
4. Check the balance of the tip tool
Check the tip tool visually at low speed (around
[1] on the switch dial).
Also check for abnormal noise during
operation.
5. Select the machining speed
○Select the optimal speed for the material while
performing trial grinding with reference to Table

6. Machining
○Place the rotating tip tool lightly against the
workpiece and machine the workpiece with
minimal pressure.
○Rather than doing the whole task in a single
action, a better finish is achieved gradually by
multiple machinings.
NOTE
○The grinder narrows toward the tip tool holder.
Place your finger on the narrow section and
hold the grinder for easy operation. (Fig. 10)
○When machining a material for the first time or
using the tip tool for the first time, perform trial
grinding first to check the optimal speed, how
to hold the grinder and how to place the tool
against the workpiece.
○If you do not achieve the expected results,
applying more pressure to the power tool will
not give better results. Nor will the machining
performance be improved by tilting the power
tool. Adjust the rotating speed or change to
another tip tool.
