1 609 929 V18 | (1.3.10) Bosch Power Tools

To start the operation of the vac, switch on the

power tool connected to the socket 7. The vac-

uum cleaner starts automatically.

When the warning light 4 flashes and the alarm

sounds, the vacuum cleaner must be checked as

described under “Malfunctions”.

To switch off the vac, switch off the power tool.

The vacuum cleaner switches off automatically

approx. 6 seconds later.

In the operating mode ENT with remote auto-

matic switching, the electronic reduced starting

current limits the power consumption when

switching on the vacuum cleaner, and thus al-

lows operation from a 16-A circuit breaker.

Electromagnetic filter cleaning

The machine is equipped with an electromag-

netic filter cleaning system, which removes dust

adhering to the folded filter 18.

The filter cleaning system must be actuated lat-

est when the vacuuming performance is no long-

er sufficient.

Set the mode selector switch 6 to the symbol

electromagnetic filter cleaning. A possibly con-

nected power tool must be switched off.

The machine vibrates for approx. 10 seconds

and switches off automatically.

Wait shortly before restarting the vacuuming op-

eration so that the dust can settle in the contain-

er.

The filter cleaning frequency depends on the

type and amount of dust. With regular usage,

the maximum vacuuming performance is main-

tained longer.

Wet Vacuuming

f Do not vacuum inflammable or explosive

fluids; for example, benzene, oil, alcohol,

solvents. Do not vacuum hot or burning

dust. Do not operate the machine in rooms

where the danger of an explosion exists.

The dusts, vapours or fluids can ignite or ex-

plode.

f The vacuum cleaner may not be used as a

water pump. The vacuum cleaner is intended

for vacuuming air and water mixtures.

f Before any work on the vacuum cleaner it-

self, pull the mains plug.

Note: Before wet vacuuming, the dust bag 17

must be removed and the container 11 must be

emptied.

The machine is equipped with level sensors 20.

The vac switches off when the maximum filling

height is reached. Set the mode selector switch

6 to off.

After vacuuming, remove the folded filter 18 in

order to avoid mildew, and allow it to dry thor-

oughly, or remove the vacuum lid 3 and allow it

to dry.

Application Possibilities

The vacuum cleaner is suitable for vacuuming

and extracting the following materials:

– Fine dusts below the general dust limit value

of 3 mg/m

3

– Dusts of mineral materials with aluminium

hydroxide

– Graphite dusts

–Aluminium dusts

– Paper dusts

–Soot dusts

– Powder-paint dusts

– Polyurethane dusts

– GFRP dusts based on epoxy resin, see manu-

facturer’s data sheet on safety

– CFP dusts based on epoxy resin, see manu-

facturer’s data sheet on safety

– Varnish dusts without carcinogenic compo-

nents

–Wood dusts

The vacuum cleaner may generally not be used

in rooms where the danger of an explosion ex-

ists.
