.
When using the machine, regularly check that
the extraction capacity is sufficient. When the
extraction capacity decreases, the filters
should be replaced. Decrease of extraction
capacity may lead to a too high concentration
of welding fumes in the workshop.
When the machine is provided with a filter pollution
indicator (option), there will be acoustic and optical
signals when the extraction capacity is too low.
7 MAINTENANCE
The machine has been designed to function without
problems for a long time with a minimum of
maintenance. In order to guarantee this some simple,
regular maintenance and cleaning activities are
required which are described in this chapter. If you
observe the necessary caution and carry out the
maintenance at regular intervals, any problems
occurring will be detected and corrected before they
lead to a total standstill of the machine.
The indicated maintenance intervals can vary
depending on the specific working and ambient
conditions. Therefore it is recommended to thoroughly
inspect the complete machine once every year in
addition to the indicated periodic maintenance. Please
contact your supplier for this inspection.

Action
Clean/empty the pre-
separator.
Check the main filter for
damage.
Check the seals of the main
filter.
Clean the integrated
aluminium prefilter at the
bottom of the main filter
and the separate aluminium
prefilter using an industrial
vacuum cleaner that meets
dust class H according to
EN 60335-2-69.
Check the mains cord for
damages.
7.2 Replacing the filters
The main filter and the HEPA filter cannot be cleaned
and therefore they have to be replaced periodically.
.
WARNING!
A saturated filter often contains dust and dirt
particles. When replacing the filters always
wear a high-quality and approved face mask.
Wrap the filters in a properly closed plastic bag
and dispose of it in compliance with the local
regulations.
It is not allowed to empty the filters using air
or by tapping.
Replace the filters in case of damage or when the
extraction capacity has become insufficient.
One must learn from experience when to replace the
filters, since the life of the filters strongly depends on
the composition of the welding fumes, the humidity,
etc.
Proceed as follows (see fig. 4 on page 45):
7.2.1 Replacement of the main filter
Use the plastic bag that contains the new main filter to
exchange the filter for a new one. Draw the bag
carefully over the old filter when removing the filter.
After that close the bag with a tie wrap or similar. The
pre-separator can also be emptied in the same bag.
• Loosen the side clips (A).
• Remove the top cover (B) from the machine.
• Carefully remove the main filter (C) from the bottom
of the machine.
• Check the seals before placing a new filter. If the
seals need to be replaced, contact your supplier.
• Place the new filter and mount the disassembled
parts in reverse order. Check that the integrated
aluminium prefilter is placed at the bottom.
