Wear personal protective equipment. Depending
on the application, use a face shield or safety gog-
gles. Wear a dust mask. Wear hearing protection.
The eye protection must be capable of protect-
ing against flying particles generated by the vari-
ous different operations. The dust mask or
respirator must be capable of filtering particles
generated by your operation. Prolonged expo-
sure to high intensity noise may cause loss of
hearing.
Wear protective gloves. Danger of injury due to
sharp-edged accessories.
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 inef-
fective. Adhesive labels are recommended.
Clean the ventilation openings on the power tool at
regular intervals using non-metal tools. The
blower of the motor draws dust into the hous-
ing. An excessive accumulation of metallic dust
can cause an electrical hazard.
Before putting into operation, check the mains
connection and the mains plug for damage.
Hand/arm vibrations
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised 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 dif-
ferent accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the
total working period.
Identify additional safety measures to protect
the operator 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 material 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 coatings, metal, some wood types,
minerals, silicate particles from materials con-
taining stone, paint solvents, wood preserva-
tives, and 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-containing 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 relevant regulations in
your country for the materials being worked.
