Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Bosch Power Tools
Operation
Start-Up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
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, press the on/off switch (3).
Press the locking mechanism (2) to lock the on/off
switch (3) in this position.
To switch off the power tool, release the on/off switch (3);
or, if the switch is locked, briefly press the on/off switch (3)
and then release it.
Always check polishing tools before using them. The
u
polishing tools 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 polishing tools that
are damaged, run untrue or vibrate during use. Dam-
aged polishing tools can burst apart and cause injuries.
Speed preselection
You can preselect the required speed using the thumbwheel
for speed preselection (1), 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
1 600
2 800
3 1100
4 1400
5 1700
6 2100
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.
