Only for EU countries
Due to the presence of hazardous com-
ponents in the equipment, waste electrical
and electronic equipment, accumulators
and batteries may have a negative impact
on the environment and human health.
Do not dispose of electrical and electronic
appliances or batteries with household
waste!
In accordance with the European Directive
on waste electrical and electronic equip-
ment and on accumulators and batteries
and waste accumulators and batteries,
as well as their adaptation to national law,
waste electrical equipment, batteries and
accumulators should be stored separately
and delivered to a separate collection point
for municipal waste, operating in accor-
dance with the regulations on environmen-
tal protection.
This is indicated by the symbol of the
crossed-out wheeled bin placed on the
equipment.
Intended use
The tool is intended for grinding, sanding, wire brush-
ing, hole cutting and cutting of metal and stone materi-
als without the use of water.

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 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 maxi-
mum 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 appropriate, wear dust
mask, hearing protectors, gloves and workshop
apron capable of stopping small abrasive or
workpiece fragments. The eye protection must

11. 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.
12. 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.
13.
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.
14. 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.

materials. Sparks could ignite these materials.
16. 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

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.

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.

power tools. A wheel intended for larger power
tool is not suitable for the higher speed of a

2. Do not position your body in line with and

4. Do not restart the cutting operation in the

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.

Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. When not using the battery cartridge, remove
it from the tool or the charger.
5. Charge the battery cartridge if you do not use
it for a long period (more than six months).

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

Grinding and sanding operation

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

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-
