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.
Rough Sanding
Attach a sanding sheet with coarse grain.
Apply only light pressure to the machine so that it
runs at a higher stroke rate and high material re-
moval is achieved.
Fine Sanding
Attach a sanding sheet with fine grain.
By lightly varying the application pressure or
changing the orbital stroke rate, the sanding plate
stroke rate can be reduced whereby the orbital ac-
tion is maintained.
With moderate pressure, move the machine in a
circular pattern or alternately in lengthwise and
crosswise directions over the workpiece. Do not tilt
the machine to avoid sanding through the work-
piece (e. g. when sanding veneer).
After finishing the working procedure, switch the
power tool off.
Polishing
Note:
For polishing, the extraction outlet piece
12
can be removed for easier handling of the machine
and to prevent damage to the workpiece.
For the polishing of weathered paint or buffing out
scratches (e.g., acrylic glass), the machine can be
equipped with appropriate polishing accessories
such as lamb’s wool bonnet, polishing felt or
sponge (accessories).
Select a low stroke rate (setting 1–2) for polishing
in order to avoid excessive heating of the surface.
Apply the polish onto a somewhat smaller surface
than you intend to polish. Work the polishing agent
in with a suitable polishing tool applying it cross-
wise or with circular motion and moderate pres-
sure.
Do not allow the polishing agent to dry out on the
surface, otherwise the surface can become dam-
aged. Do not subject the surface to be polished to
direct sunlight.
Clean the polishing accessories regularly to ensure
good polishing results. Wash out polishing acces-
sories with a mild detergent and warm water; do
not use paint thinner.
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 replacement of the supply cord is necessary,
this has to be done by Berner or an authorized
Berner service agent in order to avoid a safety haz-
ard.
When changing the sanding plate, check the seal-
ing collar
4
for damage. Have a damaged sealing
collar replaced by your Berner after-sales service
agent.
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 Guide-
line 2012/19/EU for Waste Electrical
and Electronic Equipment and its
implementation into national right,
power tools that are no longer usa-
ble must be collected separately and
disposed of in an environmentally
correct manner.
Subject to change without notice.
