Intended Use

The machine is intended for dry sanding of wood,
plastic, metal and filler material as well as painted sur-
faces.
Machines with electronic control are also suitable for
polishing.

For Your Safety

Read all instructions. Failure to fol-
low all instructions listed below may re-
sult in electric shock, fire and/or serious
injury.
SAVE THESE INSTRUCTIONS.
Hold the machine firmly with both hands while
I
working and provide for secure footing. The
machine is more securely guided with both hands.
Secure the work piece. A work piece clamped
I
with clamping devices or in a vice is held more se-
curely than by hand.
Do not work with materials containing asbes-
I
tos. Asbestos is considered carcinogenic.
Take protective measures when dust can de-
I
velop during working that is harmful to one's
health, combustible or explosive.
Some dusts are regarded as carcinogenic. Wear a
dust mask and work with dust/chip extraction
when connectable.
Keep your workplace clean. Material mixtures
I
are especially dangerous. Light metal dust can
burn or explode.
Do not use the machine with a damaged ca-
I
ble. If the cable is damaged while working, do
not touch the damaged cable but pull the
mains plug. A damaged cable increases the risk
of an electrical shock.
For machines used outdoors, connect to the
I
mains using a fault current (FI) protection
switch.
Use the electro-tool only for dry sanding. The
I
penetration of water into the electro-tool increases
the risk of an electrical shock.
Take care that no persons are endangered by
I
flying sparks. Remove combustible material
from the vicinity. When sanding metals, sparks
are produced.
Caution, fire hazard! Avoid overheating of the
I
sanded material and the electro-tool. Always
empty the dust container before pauses in the
work. For unfavourable conditions such as flying
sparks when sanding metals, sanding dust in the
3 609 929 A92 • (06.07) T
dust bag, micro filter or paper sack (or in the filter
sack or filter of the wet/dry vacuum cleaner) can
self-ignite, especially when mixed with remainders
of varnish, polyurethane or other chemical materi-
als and when the sanded work piece is hot after
long periods of working.
Replacing the Sanding Sheet/
Sanding Plate
Before any work on the machine itself, pull the
I
mains plug.
Selection of the Sanding Plate
Depending on the application, the machine can be
equipped with sanding plates of different hardness
(see Application Table):
– Extra soft sanding plate (III): Suitable for polishing
and sensitive sanding (also for curved surfaces).
– Soft sanding plate (II): Suitable for universal usage
on flat surfaces.
– Hard sanding plate (I): Suitable for high sanding
performance on flat surfaces.
Example:
Changing the Sanding Plate
Replace damaged sanding plates without delay.
To replace the sanding plate 9, pull off the sanding
sheet or polishing tool. With the Allen key 7, loosen
and remove the screw 8.
When placing on the sanding plate, take care
that the teeth of the drive piece engage in the re-
cesses of the sanding plate.
Hold the sanding plate and firmly tighten the screw 8
with the Allen key 7.
Selecting the Sanding Sheet
Depending on the material to be worked and the de-
sired material removal, various sanding sheet qualities
are to be used.
Changing the Sanding Sheet
Lift the sanding sheet 6 at the edge and pull it off the
sanding plate 9. Clean the sanding plate 9, if required.
Press the new sanding sheet 6 against the bottom of
the sanding plate. To ensure optimum dust extraction,
the holes of the sanding sheet must match with those
of the sanding plate.
