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.
The vibrational emission values are given for dry grinding of
metal with grinding wheels. Other applications, such as belt
sanding, can lead to other vibrational emission values.

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, and antifouling paints for vessels, can trig-
ger 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.

Take care that the inner flange is mounted firmly on the
output spindle and that the centering sleeve is mounted.
Make sure to check that the grinding accessory is wider
than the height of the centering sleeve. Pay attention that
the grinding accessory is properly centred between the
inner flange and the threaded flange.
Using the same pressure, move the power tool back-
wards and forwards across the surface of the work piece
to prevent it from becoming too hot.

Motor protection switch MShy664-1 (see page 6).

If given, the motor protection switch switches off the
power tool in case of overload. After approx. 30 seconds
upon actuation, the electronic system can be reset via
button (a).
Do not actuate button (a) until after having released the
power tool’s switch.

Repair and customer service.

When working metal under extreme operat-
ing 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 com-
pressed air, and connect a residual current device (RCD)
on the line side.
If the supply cord of this power tool is damaged it must
be replaced by a specially prepared cord available
through the FEIN customer service centre.

If required, you can change the following parts yourself:

Application tools, Threaded flange, Inner flange, Center-
ing sleeve.
