an effective form of dust extraction by means of the
integratd suction turbine and dust bag.
Push the dust bag with the locking connection 10 from
behind onto the fitting on the blower flange and press it
on. The locking connection engages when turned clockwise
and thereby secures the dust bag against being pulled off.
9. Practical Tips
Sanding surfaces
Only perfect sanding sheets will give a good sanding
performance and protect the machine.
Observe uniform feed. Less contact pressure gives a better
sanding performance and protects the machine and sanding
tools.
Different rubber backing pads and sanding wheels should
be used depending on the material.
The abrasive power and the sanding finish are determined
primarily by the choice of sanding disc (grain), speed of
the rubber backing pad and contact pressure (see
application table).
Place the whole sanding area of the eccentric disc sander
onto the material ehich requires sanding. Switch on the
machine and move over the work-piece, applying moderate
pressure.

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 by 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, parallel 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 oad
speed by removing the contact pressure and lift machine
off the workpiece.
Polishing
For polishing weather-beaten paintwork or for touching-up
scratches, (e.g. acrylic glass) the eccentric disc grinder
can be fitted with the appropriate polishing tools, for
example, a lamb´s wool attachement 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, appliying moderate pressure, in a
crosswise or circular motin and then allow to dry slightly.
Mount the lamb´s wool disc attachment onto the backing
pad.
Polish up the dried polish in a crosswise or circular motion.
In order to achieve optimum polishing results, the polishing
tools must be cleaned regularly. It is recommended to wash
the polishing tools with a mild detergent and warm water
(do not use diluting agents).
10. 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 regulary with a cloth
without cleaning agent.
The rubber seal 14 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 STORCH after-sales services station.
After heavy use over a long period, the machine should be
taken to a STORCH service location for an inspection and
thorough cleaning.
11. Environmental Protection
STORCH takes back worn-out machines for the
pirpose of resource-saving recycling. As a result
of their modular construction, STORCH
machines can be very easily dismantled into
their reusable materials.
Give your worn-out STORCH machine to your dealer or send
it directly to STORCH.
