Why does the main filter clog up quickly when picking up fine dust (e.g. when working with electric power tools)?
Cause:
Filter bag has been forgotten. (Suitability for picking up fine dust is limited when filter bag is not fitted)
Remedy:
Always fit a filter bag.
Dust is expelled from the vacuum – why?
Cause:
Suction hose is faulty or not properly engaged.
Filter missing or faulty.
Filter bag has not been fitted.
Remedy:
Check suction hose and filter, engage properly or replace if necessary.
Fit a filter bag.
Vacuum cannot be set to stage 2 (automatic on/off facility for electric power tools)?
Cause:
Stage 2 is designed for operation with electric power tools only.
Remedy:
The vacuum starts when the electric power tool is switched on. Vacuum continues running for about 15-20 seconds after the electric power tool is switched off and then shuts down.
Why does the (NT) vacuum have no suction power?
Cause:
Filter bag is full.
Cartridge filter or flat filter is dirty.
Tool, tube or hose blocked.
Remdy:
Fit a new filter bag.
Clean the cartridge/flat filter.
Clean the tool, tube and hose.
The vacuum switches itself off?
Cause:
Waste container is full.
Level sensors and the housing are wet. This can create a damp bridge.
