ATTENTION!
Always wear face mask and gloves during filter
exchange/cleaning.
6.2.1 LongLife main filter
The main filter cannot be cleaned and must be replaced
whenever necessary. The lifespan of the filter strongly depends
on the welding process, the composition of the welding fumes,
the intensity of use and the humidity. The frequency of
replacement will be a matter of experience.
Replace the main filter:
- when the filter pollution indicator (Fig. 5.1C) shows that the
filter cartridge is saturated or clogged; or
- when the airflow is reduced to the point that extraction
performance is no longer satisfactory; or
- when it has been damaged.
To replace the main filter proceed as follows.
Fig. 6.1
• Turn off the machine and disconnect it from the mains.
