voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.
Switching on/off
To start the power tool, push the on/off switch (5) forward
and then press it down.
To lock the on/off switch (5) in position, push the on/off
switch (5) further forward.
To switch off the power tool, release the on/off switch (5);
or, if the switch is locked, briefly press the on/off switch (5)
and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Speed preselection
You can preselect the required speed using the thumbwheel
for speed preselection (4), even during operation. The re-
quired speed depends on the material and the working con-
ditions; it can be ascertained through practical tests.
Thumbwheel position No-load speed (min
1 750
2 1200
3 1600
4 2000
5 2400
6 3000
The rated speed of the accessory must be at least
u
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fly apart.
Constant Electronic control
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.

Working advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Clamp the workpiece if it is not secure under its own
u
weight.
Do not load the power tool so heavily that it comes to a
u
stop.
If the power tool has been subjected to a heavy load,
u
continue to run it at no-load for several minutes to
cool down the accessory.
For sanding soft materials such as plaster or paint, it is
u
best to use a rubber sanding pad (18) with sanding

sheet (19). Cup brushes (21) and disc brushes are suit-
able for removing rust.
Polishing
For polishing weathered lacquers and redressing scratches
(e.g. acrylic glass), the power tool can be fitted with an ap-
propriate polishing tool, e.g. lambswool bonnet, polishing
felt or polishing sponge (accessory).
Select a low speed for polishing (level 1–2) to prevent the
surface from overheating.
Apply the polish to an area slightly smaller than the area
which you intend to polish. Using the appropriate polishing
tool, work in the polish using side-to-side or circular motions
and applying moderate pressure.
Do not allow the polish to dry out on the surface; this may
damage the surface. Do not expose the surface which you in-
tend to polish to direct sunlight. Clean the polishing tools
regularly to ensure good polishing results. Wash the polish-
ing tools with mild detergent and warm water; do not use
thinning agents.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
-1 u
)
the power tool and the ventilation slots clean.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD) upstream. When
machining metals, conductive dust can settle inside the
power tool, which can affect its protective insulation.
Store and handle the accessories carefully.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
