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.
Adjust the rotation selector switch only when the
machine is at a complete stop.
Thermal overload of the power tool is indicated
through flashing of the LED in the handle.
In case of overload, the machine switches off.
Danger of burning. The application
WARNING
tool can become hot during opera-
tion. Allow the application tool to cool down:
– after placing the power tool down
– prior to tool changing.
To avoid accidental starting, e. g., during transport, set
the rotation selector switch to the centre position.
Apply the power tool to the nut or screw only when
switched off, as a rotating application tool could slip off.
Hold the power tool perpendicular to the screw at an
angle of 90° when screwing in and unscrewing.
If the power tool is applied inclined, the screw head can
be damaged and the force is not transferred to the
screw.
An unnecessary long impact period increases the wear
of the power tool.
Determine the impact duration for the respective
screwdriving application and check the actually reached
tightening torque with a torque wrench.
Orientation values for the impact duration are shown in
the diagram on page 13.

Handling the battery.
Store, operate and charge the battery only using FEIN
battery chargers within the battery operating-tempera-
ture range between 5 °C – 45 °C (41 °F – 113 °F). At
the beginning of the charging procedure, the battery
temperature must be within the battery operating-tem-
perature range.
