higher numbers indicate a high speed, while the smaller
ones represent a low speed.
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
The electronic soft start limits the torque when the power
tool is switched on and increases the service life of the mo-
tor.
Switching On/Off
u
Make sure that you are able to press the On/Off switch
without releasing the handle.
To
switch on
the power tool, slide the on/off switch

for-
ward so that
"I"
appears on the switch.
To
switch off
the power tool, slide the on/off switch
(3)
backwards so that
"0"
appears on the switch.

Working Advice
u
Pull the plug out of the socket before carrying out any
work on the power tool.
u
Always wait until the power tool has come to a com-
plete stop before placing it down.
u
Do not put the power tool down on its side.
This could
permanently warp the sanding pad.
u
This power tool is not suitable for bench-mounted use.
It must not be clamped into a vice or fastened to a work-
bench, for example.
Sanding Surfaces
Switch the power tool on, place the entire sanding surface
against the surface of the workpiece and apply moderate
pressure as you move the sander over the workpiece.
The material removal rate and sanding result are primarily
determined by the choice of sanding sheet, the preselected
speed setting and the contact pressure.
Only immaculate sanding sheets achieve good sanding per-
formance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to in-
crease the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
Do not use a sanding sheet for other materials after it has
been used to work on metal.
Use only original
Bosch
-sanding accessories.
Sanding Close to Edges (see figures F–G)
Thanks to the removable brush segment, you can reduce the
lateral distance between the wall/ceiling and the sanding
pad.
– Press and hold the locking mechanism
(12)
for the brush
segment
(18)
.
– Swivel the brush segment
(18)
forwards and remove it.
– To
insert
, hook the brush segment
(18)
onto the oppos-
ite side of the locking mechanism
(12)
, and swivel it to-
wards the sanding head
(11)
until it clicks into place.
Adjusting the Internal/External Airflow
Depending on the vacuum pressure, the perceived tool
weight can be reduced.
You can switch between different air flow operating modes
depending on the intended use. Turn the suction power ad-
justing lever
(13)
to one of the 3 positions.
