Hepa Filter - Husqvarna T 4000 Bedienungsanleitung

The filter must be cleaned from time to time. This must be done before changing the bag collection system and should also be
done when work is completed or when there is poor suction.
Procedure: Cover the inlet, if applicable, use attached cover. First let the machine build up vacuum for four to five seconds
then quickly push down on the key and release it. Repeat the procedure five times. It is important to let the machine rebuild
the vacuum in between every repetition.
Turn off the motor and wait until it stops completely, then uncover the inlet.
If suction remains poor, the pre-filter needs to be replaced. If suction still remains poor afterwards, the Hepa filters needs to
be replaced. See instructions in chapter 6. FILTER CHANGE.
The dust extractors are mainly equipped with Longopac system for effective dust storage or a regular plastic bag system
depending on model. Longopac is a 22 m long plastic tube that will be divided into plastic bags using the zip ties attached
with the machine.
To assemble a new Longopac bag: Release the belt holding the last bag. Remove the holder, put in a new Longopac bag &
pull out the inner end upwards. Assemble the holder on to the machine and strap the opening facing upwards with the belt.
Pull down the outside end and close it using a zip tie.
All dust extractors can be used with original Husqvarna dust bags for single use. Also all models can be fitted with the
longopac system.
Only change Longopac or regular bag after filter cleaning cycle have been completed.
Risk of dust dispersion - Use personal safety equipment
Unhealthy dust can be spread during filter change. Accordingly, the user should wear protective glasses, protective
gloves, and a breathing mask conforming to protection class FFP3.
WARNING
Remember to switch off the machine and pull the plug out of the outlet before servicing.
