accumulation of powdered metal may cause electrical
hazards.
Do not operate the power tool near flammable materi-
u
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
u
Using water or other liquid coolants may result in electro-
cution or shock.
Hold power tool by insulated gripping surfaces only,
u
when performing an operation where the cutting ac-
cessory may contact hidden wiring. Cutting accessory
contacting a "live" wire may make exposed metal parts of
the power tool "live" and could give the operator an elec-
tric shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, sanding band, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating ac-
cessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the accessory's rota-
tion.
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 direc-
tion of the wheel's movement at the point of pinching. Abras-
ive 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.
Maintain a firm grip on the power tool and position
u
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if
proper precautions are taken.
Use special care when working corners, sharp edges
u
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.
Do not attach a toothed saw blade. Such blades create
u
frequent kickback and loss of control.
Always feed the bit into the material in the same dir-
u
ection as the cutting edge is exiting from the material
(which is the same direction as the chips are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
Always have the work securely clamped. The aceessor-
u
ies will grab if they become slightly canted in the groove,
and can kickback and you could lose control of the tool.
Safety warnings specific for grinding
Use only wheel types that are recommended for your
u
power tool and only for recommended applications.

Additional safety information
Do not touch grinding discs until they have cooled
u
down. The discs can become very hot while working.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
This power tool is not suitable for bench-mounted use.
u
It must not be clamped into a vice or fastened to a work-
bench, for example.
In case of damage and improper use of the battery, va-
u
pours may be emitted. The battery can set alight or ex-
plode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery in the manufacturer's products.
u
This is the only way in which you can protect the battery
against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.
