6.1 Automatic lter cleaning
Automatic lter cleaning automatically cleans the dust extractor's coarse lter when it becomes
blocked. This occurs by electromagnets connecting to buttons 1 and 2, whereupon the dust ex-
tractor's control panel can perform lter cleaning automatically or via a button push. Filter cleaning
occurs when one or more of the following conditions are met:
• Set time between lter cleans reached.
• Filter status - Standard is 100%.
Lower values giver more frequent pulses.
• Flow limit - Standard is 240 m³/h (150cfm).
Higher values give more frequent pulses.
To adjust pre-set values, see 4.9 Display information menu.
