After working gypsum-containing materials: Blow out
the ventilation openings of the power tool and the
switch element with dry and oil-free compressed air.
Otherwise, gypsum-containing dust can settle in the
power tool housing and switch element, which can
harden in connection with humidity. This can impair the
switching mechanism.
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.
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 62841 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.

Operating Instructions.
Do not use accessories not specifically intended and
recommended for this power tool by FEIN. The use of
non-original FEIN accessories can lead to overheating
of the power tool and destroy it.
Guide the power tool toward the work piece only
when switched on.
The application tool can be offset in 30° steps and fas-
tened in the most favourable working position.
Changing the tool (see pages 4/5).
Do not switch the power tool on while the clamp-
ing lever is open. Otherwise there is danger of
crushes or contusions to the hand and fingers.
Do not actuate the clamping lever while the power
tool is running. Otherwise there is danger of
injury.
Do not reach into the area of the clamping jaws.
Otherwise there is danger of crushes or contu-
sions to the fingers.
Do not operate the power tool with with open
clamping jaws and without an application tool!
This could damage the power tool.
When the clamping jaws are open before the
application tool is inserted, pivot the clamping
lever toward the front and then back again.
The
clamping jaws are closed now. The application
tool can be inserted.
