size of the disk. The more abrasive grains included on
the sandpaper, the better flatness and parallelism can be
achieved via sanding , while the sanding efficiency will
fall accordingly and vice versa. Therefore, the sandpaper
(Ø 225mm) is recommended upon actual needs.
Connecting the extractor (Fig.4)
Installation Guide: Insert the hose into the connector.
Push item A into the connector to lock the hose with

Working with the power tool
Always hold the wall sander with both hands! Keep your
hands away from the sanding head. Otherwise, your
hand could become caught, as the sanding head swi-
vels in different directions.
1. Attach sanding head.
2. Attach sanding tool.
3. Connect dust extraction system.
4. Insert mains plug.
5. Switch on dust extraction system.
6. Switch on the device.
7. Grip the wall sander by both handles. Press the wall
sander gently against work surface (the pressure
should be just enough to ensure that the sanding head
is flush with the work surface) .
Sanding head operation instruction
a) Brushing ring
A brush type rim surrounds the round sanding head. This
time 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 anding
tool comes into contact with the work surface. This avo-
ids a sickle-shaped depression ca used 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.
b) 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 re placed if it is
damaged or severely abraded.
c) Triangular sanding head
The triangular sanding head does not rotate, but vibrate.

Maintenance and care

a) Replacing the sanding plate on the round sanding
head.
If the round viscid disc is damaged in the work, a new
viscid disc can be purchased from our company for re-
placement. Remove the sandpaper, put the Allen wrench
into the hexagon hole in the center of the viscid disc and
then rotate to take off the damaged viscid disc. Install
the new viscid disc.
b) Cleaning
Regular cleaning shall be conducted after grinding.
• Cleaning the devices frequently may help to extend
operating life and reduce repair rate. It is recommen-
ded to clean the connection sets and components of
electric motor without application of water.
• Timely cleaning is recommended after the application
of the devices
• Clean the devices with a hairbrush and a piece of dry
cloth, or simply blow it with high pressure gas.

Storage and transport

1. Whenever you do not use the power tool, you must
keep it in a dry and weil ventilated place out of the
reach of children, e.g. on a high cabinet or in a
closed place.
2. Keep power tool, instruction manual and accesso-
ry parts, if any, together in the original packaging,
if possible. Thus you have all information and parts
available at any time.
3. Always hold the power tool by its handle.
4. To avoid transport damages, you must pack the po-
wer tool or use the original packaging.
5. Protect the power tool against vibrations and shock,
