Maintenance And Cleaning; Wet Vacuuming - Bosch GAS 50 M Bedienungsanleitung

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 latest
when the vacuuming performance is no longer
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 con-
tainer.
The filter cleaning frequency depends on the type
and amount of dust.
With regular usage, the maximum vacuuming
performance is maintained longer.

Wet Vacuuming

Danger of explosion and fire! Do not vac-
uum 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 dust bag 17 must be removed before
wet vacuuming.
Empty the container before wet vacuuming.
The machine is equipped with level sensors 20.
The machine switches off when the maximum fill-
ing height is reached. Set the switch to off.
Before opening and emptying, pull the plug from
the socket in all cases.
After vacuuming, remove the folded filter 18 and
allow it to dry thoroughly, in order to avoid mil-
dew. Also remove the vacuum top 3 and allow it
to dry, too.

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
Always keep the machine clean.
When the control indicator flashes during IS (in-
dustrial) operation mode, or if the alarm sounds
during ENT (dedusting) mode, the dust bag must
be exchanged.
Caution! The machine contains dust which is
harmful to one's health. Emptying and mainte-
nance, including the disposal of dust collection
containers, may be carried out only by special-
ists. Suitable safety equipment is required. Do
not operate the machine without the complete
filter system.
At least once every year a dust-technical test is to
be carried out by the manufacturer or a trained
professional, e. g. to check for damage to the fil-
ter, tightness of the machine and function of the
control machine.
For class M vacuum cleaners which have been
used in contaminated areas, the exterior and all
unit parts should be cleaned or treated with seal-
ants. All contaminated parts that cannot be
cleaned satisfactorily during maintenance and re-
pair must be disposed of. Such parts must be dis-
posed of in impermeable bags, in accordance
with the relevant regulations for the disposal of
such waste materials.
For maintenance carried out by the user, the unit
must be dismounted, cleaned and maintained as
far as possible without presenting any danger to
the maintenance personnel or other persons. In
order to prevent possible danger, the vacuum
cleaner should be cleaned prior to dismounting.
The area in which the vacuum cleaner will be dis-
mounted should be well ventilated. After the
maintenance, the maintenance area and per-
sonal protective equipment should be cleaned.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit order number
given on the nameplate of the machine.
