Working Advice
 Before any work on the machine itself, pull the mains
plug.
 Clamp the workpiece if it does not remain stationary
due to its own weight.
 Do not strain the machine so heavily that it comes to a
standstill.
 After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
For sanding applications on soft materials, e. g., gypsum or
paint, it is recommended to use the rubber sanding plate 18
with sanding sheet 19.
Cup brushes 21 and wheel brushes are suitable for rust re-
moval.
Polishing
For the polishing of weathered paint or buffing out scratches
(e.g., acrylic glass), the machine can be equipped with appro-
priate polishing accessories such as lamb's wool bonnet, pol-
ishing felt or sponge (accessories).
Select a low speed for polishing (stage 1 – 2) in order to avoid
excessive heating of the surface.
Apply the polish onto a somewhat smaller surface than you in-
tend to polish. Work the polishing agent in with a suitable pol-
ishing tool applying it crosswise or with circular motion and
moderate pressure.
Do not allow the polishing agent to dry out on the surface, oth-
erwise the surface can become damaged. Do not subject the
surface to be polished to direct sunlight.
Clean the polishing accessories regularly to ensure good pol-
ishing results. Wash out polishing accessories with a mild de-
tergent and warm water; do not use paint thinner.
