determined by carrying out a practical test.

Coarse sanding
Attach a coarse grain sanding disc. Only apply light
pressure to the eccentric disc sander, so that the
rubber backing pad runs at a higher speed, thereby
removing a greater quantity of the material.
Precision sanding
Attach a sanding disc which has a finer grain. The
speed of the rubber backing pad can be reduced by
lightly varying the contact pressure, as a result of
which the eccentric movement of the sander is
retained and the sanding finish is equivalent to that
produced by a vibrating sander.
Move the eccentric sander in a circular motion, paral-
lel to the material, or move the sander in alternating
lengthwise and crosswise directions.
Do not tilt the eccentric disc sander, otherwise the
sander may sand through the work-piece (e. g.
veneer).
On completion of work, reduce the rubber backing pad
speed by removing the contact pressure and lift
machine off the workpiece.

Polishing
For polishing weather-beaten paintwork or for touch-
ing-up scratches, (e. g. acrylic glass) the eccentric
disc grinder can be fitted with the appropriate polish-
ing tools, for example, a lamb's wool attachment or
a polishing felt/sponge (auxiliary).
Select low speed for polishing (step 1 – 2) in order
to avoid excess heating of surface.
Attach the polishing sponge to the rubber backing
pad.
Apply polish to the location which requires polishing.
Work in the polish, applying moderate pressure,
in a crosswise or circular motion and then allow to dry
slightly.
Mount the lamb's wool disc attachment onto the back-
ing pad.
Polish up the dried polish in a crosswise or circular
motion.
In order to achieve optimum polishing results, the pol-
ishing tools must be cleaned regularly. It is recom-
mended to wash the polishing tools with a mild deter-
gent and warm water (do not use diluting agents).

11 Maintenance Measures

Before any work on the machine itself, pull the
mains plug!
Always keep the ventilation slots clean.
Wipe off the accessible plastic parts regularly with
a cloth without cleaning agent.
The rubber seal 18 protects the drive against any dirt
and thereby also from increased wear and a shorter
service life of the drive parts.
The rubber seal must therefore be checked regularly
for damage. If the seal is damaged the machine
should be taken to a Kress after-sales service station.
After heavy use over a long period, the machine
should be taken to a Kress service location for an
inspection and thorough cleaning.

12 Environmental Protection

Kress takes back worn-out machines
for the purpose of resource-saving
recycling. As a result of their modular
construction, Kress machines can be
very easily dismantled into their reusa-
ble materials.
Give your worn-out Kress machine to your dealer or
send it directly to Kress.
