REPLACING THE SAND PAPER/ SANDING PLATE
1
Remove the plug from the socket before carrying out any adjustment,
servicing or maintenance.
a) Selecting the Sand paper
Depending on the material to be worked and the desired material
removal, various Sand paper qualities are to be used:
- Use coarse grits to sand down rough finishes medium grit to
smooth the work and fine grit to finish off.
- The higher the grade number, the finer the grit. For rough work,
start with a low grade of grit. (e.g.60grit) and change to a higher, finer
grade (e.g.120grit) for finishing.
b) Replacing the Sand paper
Lift the Sand paper at the side and pull it off the sanding plate. Clean
the sanding plate, if required. Press the new Sand paper against the
bottom of the sanding plate. To ensure optimum dust extraction, the
holes of the Sand paper must match with those of the sanding plate.
c) Selection of the Sanding Plate
Depending on the application, the machine can be equipped with
sanding plates of different hardness
- Soft sanding plate: Suitable for polishing and sensitive sanding (also
for curved surfaces).
- Middle sanding plate: Suitable for universal usage on flat surfaces.
- Hard sanding plate: Suitable for high sanding performance on flat
surfaces.
d) Replacing the Sanding Plate (See Fig A)
To replace the sanding plate, pull off the sand paper or polishing tool.
Loosen and remove the screw.
Replace damaged sanding plates without delay.
- Dust produced while working can be detrimental to health,
inflammable or explosive. Suitable protection measures are required.
Examples: Some dusts are considered to be carcinogenic. Use
suitable dust/chip extraction and wear a dust protection mask.
- Light metal dust can burn or explode. Always keep the work place
clean since material mixtures are especially dangerous.
Caution: Fire hazard! For unfavorable conditions such as
flying sparks when sanding metals, sanding dust in the 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 materials and when the sanded work piece is hot
after long periods of working. Avoid overheating the object
being sanded as well as the machine and always empty the
dust container before pauses in the work.

performance, always empty the dust bag in time. Open the zip and
empty the dust from the bag.
