Always work with the auxiliary handle. The auxiliary
handle 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 stand-
ardised 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 accesso-
ries 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 expo-
sure level over the total working period.
Identify additional safety measures to protect the oper-
ator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organi-
sation of work patterns.
Handling hazardous dusts
For work procedures with this power tool where
material is removed, dusts develop that can be hazard-
ous 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 parti-
cles 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 pro-
vide for good ventilation of the workplace. Leave the
processing of asbestos-containing materials to special-
ists.
Wood and light-metal dust, hot mixtures of grinding
dust and chemical materials can self-ignite under unfa-
vourable 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 instruc-
tions, as well as the relevant regulations in your country
for the materials being worked.
Operating Instructions.
The self-start lock prevents the angle grinder from
automatically restarting again, even after a brief inter-
ruption of the power supply, e. g., from a pulled mains
plug.
The angle grinders are equipped with overload and
blocking protection. In case of overload or blocking of
the application tool, the power supply is interrupted. In
this case, switch the power tool off, remove it from the
workpiece and check the application tool. Afterwards,
switch the power tool on again.
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
ratcheting noise starts. Fold the rapid-clamping lever
back until it engages (see page 6).
Notes: The electronic braking system EBS starts the
braking 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 opera-
tion or when the mains plug is pulled during operation,
the grinding accessory runs out without a braking
effect.
Repair and customer service.
When working metal under extreme oper-
ating conditions, it is possible for conductive
dust to settle in the interior of the power
tool. The total insulation of the power tool can be
impaired. Blow out the interior of the power tool via
the ventilation slots frequently with dry and oil-free
compressed air, and connect a residual current device
(RCD) on the line side.
Products that have come into contact with asbestos
may not be sent in for repair. Dispose of products con-
taminated with asbestos according to the applicable
country-specific regulations for such disposal.
WSB20/WSB25: Manually screw on the clamping unit
to protect it against damage and debris.
When the machine's power supply cord is damaged, it
must be replaced by the manufacturer or their repre-
sentative.
