Safety warnings specific for wire brushing opera-
tions
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.
If the use of a guard is recommended for wire brushing,
do not allow any 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.
Further safety warnings
Use elastic spacers/liners when these are provided with
the grinding accessory.
Make sure that the application tools are mounted in
accordance with the manufacturers instructions. The
mounted application tools must be able to rotate freely.
Incorrectly mounted application tools can become loose
during operation and be thrown from the machine.
Handle grinding accessories carefully and store them
according to the manufacturer’s instructions. Damaged
grinding accessories can develop cracks and burst during
operation.
When using application tools with a threaded insert, take
care that the thread in the application tool is long enough
to hold the spindle length of the power tool. The thread in
the application tool must match the thread on the spindle.
Incorrectly mounted application tools can loosen during
operation and cause injuries.
Beware of any concealed electric cables, gas or water
conduits; check the working area with a metal detector,
for example, before commencing work.
Use a stationary extraction system, blow out ventilation
slots frequently and connect a residual current device
(RCD) on the line side. When working metal under
extreme operating conditions, it is possible for conduc-
tive dust to settle in the interior of the power tool. The
total insulation of the power tool can be impaired.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Always work with the auxiliary handle. The auxiliary han-
dle ensures reliable guiding of the power tool.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Recommendation: The tool should always be supplied
with power via a residual current device (RCD) with a
rated current of 30 mA or less.
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised test given in EN 60745 and may be used to compare
one tool with another. It may be used for a preliminary
assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However if the tool is used
for different applications, with different accessories or
poorly maintained, the vibration emission may differ.
This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool is
switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level
over the total working period.
Identify additional safety measures to protect the opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.
Handling hazardous dusts
For work procedures with this power tool where mate-
rial is removed, dusts develop that can be hazardous to
one’s health.
Contact with or inhaling some dust types, e. g. asbestos
and asbestos-containing materials, lead-containing coat-
ings, metal, some wood types, minerals, silicate particles
from materials containing stone, paint solvents, wood
preservatives, antifouling paints for vessels, can trigger
allergic reactions to the operator or bystanders and/or
lead to respiratory infections, cancer, birth defects or
other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched
appropriately for the developing dust, as well as personal
protective equipment and provide for good ventilation of
the workplace. Leave the processing of asbestos-contain-
ing materials to specialists.
Wood and light-metal dust, hot mixtures of sanding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer’s working instructions, as well as the rele-
vant regulations in your country for the materials being
worked.
Operating instructions.
The self-start lock prevents the angle grinder from auto-
matically restarting again, even after a brief interruption
of the power supply, e. g., from a pulled mains plug.
WSG20/WSG25:
Press the locking button only when the motor is
stopped (see page 5).
WSB20/WSB25:
Turn the clamping unit in when the rapid-clamping lever
is open. Manually tighten the clamping unit until a ratch-
eting noise starts. Fold the rapid-clamping lever back until
it engages (see page 6).
Notes: The electronic braking system EBS starts the brak-
ing effect with a brief delay when the machine runs down
and stops the grinding accessory within a few seconds.
When the power supply is interrupted during operation
or when the mains plug is pulled during operation, the
grinding accessory runs out without a braking effect.
