Polishing
For polishing, fit the eccentric sander with an appropri-
ate polishing tool.
Select a low speed for polishing (step 1–2) to
avoid excessive heating of the surface.
Apply polishing agent crosswise or in a circular motion
with a sponge and moderate pressure and then allow
to dry lightly.
Polish the partially dried polishing agent with cross-
wise or circular motions using a lamb's wool polishing
bonnet.
Cleaning the polishing tools.
It is recommended to wash the polishing tools with a
mild detergent and warm water (do not use paint thin-
ning agents).
Maintenance and Cleaning
Before any work on the machine itself, pull the
I
mains plug.
For safe and efficient working, always keep the ma-
I
chine and the ventilation slots clean.
