Operating instructions
Brush ring
A brush-type rim surrounds the round sanding
head. This rim has two functions:
– As the ring projects above the surface of the
sanding plate, it is the ring which comes into
contact with the work surface first.
As a result, the sanding head is brought
parallel to the work surface before the
sanding tool comes into contact with the
work surface. This avoids a sickle-shaped
depression caused by the edge of the
sanding disc.
– The ring also retains the dust until
it is extracted by the dust extractor.
If the brush ring is damaged or shows excessive
wear, it should be replaced (see section entitled
"Maintenance and care"). Replacement brush
rings are available from any FLEX customer
service centre.
Gimbal bearings
The sanding head can be swivelled in different
directions.

Adjust the sanding plate to the work surface.
As a result, the user can sand the upper,
middle and lower wall areas or ceiling profiles
without having to change his position.
Round sanding head
When working on the round sanding head,
apply only as much pressure as is required to
keep the sanding tool in contact with the work
surface. Excessive pressure may result in
a disagreeable spiral pattern of scratches and
an uneven work surface.
Move the sander constantly while the sanding
tool is in contact with the work surface. In doing
so, ensure that you move the sander evenly and
over a wide area. If you stop the sander on the
work surface or move the sander unevenly, this
may result in a disagreeable spiral pattern of
scratches and an uneven work surface.
The sanding disc can be replaced if it is
damaged or severely abraded (see section
entitled "Maintenance and care").
Triangular sanding head
The triangular sanding head does not rotate,
but vibrates.
