Finish-sanding Plate (without velcro backing)
(see figure B)
When operating mainly with standard sanding
sheets without velcro backing, it is recommended
to use the finish-sanding plate without velcro back-
ing. Due to its plane sanding plate surface, opti-
mum results are achieved, especially for finish
sanding.
Auxiliary Handle
The auxiliary handle 1 enables convenient handling
and optimal distribution of power, especially at
high removal rates.
Fasten the auxiliary handle 1 with screw 2 to the
casing.
Operation
Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Power tools marked with 230 V can also be op-
erated with 220 V.
Switching On and Off
To start the machine, press the On/Off switch 4
and keep it pressed.
To lock the pressed On/Off switch 4, press the
lock-on button 5.
To switch off the machine, release the On/Off
switch 4 or when it is locked with the lock-on button
5, briefly press the On/Off switch 4 and then re-
lease it.
To save energy, only switch the power tool on
when using it.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital
stroke rate 3, you can preselect the required orbital
stroke rate, even during operation.
The required stroke rate depends on the material
and the working conditions and can be determined
through practical testing.
Working Advice
Wait until the machine has come to a standstill
before placing it down.
Before any work on the machine itself, pull the
mains plug from the socket outlet
The removal capacity during sanding is mainly de-
termined by the selection of the sanding sheet as
well as the preselected orbital stroke rate.
14 | English
Only flawless sanding sheets achieve good sand-
ing capacity and extend the service life of the ma-
chine.
Pay attention to apply uniform sanding pressure;
this increases the working life of the sanding
sheets.
Intensifiying the sanding pressure does not lead to
an increase of the sanding capacity, but to in-
creased wear of the machine and the sanding
sheet.
A sanding sheet that has been used for metal
should not be used for other materials.
Use only original Berner sanding accessories.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
In all correspondence and spare parts orders,
please always include the 6-digit order number giv-
en on the nameplate of the machine.
Disposal
The machine, accessories and packaging should
be sorted for environmental-friendly recycling.
Do not dispose of power tools into household
waste!
Only for EC countries:
According to the European Directive
2012/19/EU for Waste Electrical and
Electronic Equipment and its imple-
mentation into national right, power
tools that are no longer usable must
be collected separately and disposed
of in an environmentally correct man-
ner.
Subject to change without notice.
