Maintenance And Cleaning - Bosch GAS 50 M PROFESSIONAL Bedienungsanleitung

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
Always keep the machine clean.
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 filter, tightness of the machine and func-
tion 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
sealants. All contaminated parts that cannot be
cleaned satisfactorily during maintenance and
repair must be disposed of. Such parts must be
disposed of in impermeable bags, in accord-
ance with the relevant regulations for the dis-
posal of such waste materials.
For maintenance carried out by the user, the
unit must be dismounted, cleaned and main-
tained 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 dismounted should be well venti-
lated. Wear personal protective equipment dur-
ing maintenance. After the maintenance, the
maintenance area should be cleaned.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-
sales service agent for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article
number given on the nameplate of the vacuum
cleaner.
