Polishing (PEX 270 AE)
For the polishing of weathered paint or buffing
out scratches (e.g., acrylic glass), the machine
can be equipped with appropriate polishing ac-
cessories such as lamb’s wool bonnet, polishing
felt or sponge (accessories).
Select a low stroke rate (setting 1
–2) for polish-
ing in order to avoid excessive heating of the
surface.
Apply polishing agent crosswise or in a circular
motion with a polishing sponge and moderate
pressure, and then allow it to dry lightly.
Polish the partially dried polishing agent with
crosswise or circular motions using a lamb’s
wool polishing bonnet.
Clean the polishing accessories regularly to en-
sure good polishing results. Wash out polishing
accessories with a mild detergent and warm wa-
ter; do not use paint thinner.
