Dust-laden air is then sucked through the inlet valve at high speed via the suction hose. The air is slowed down
by the cyclone and coarse dust particles are separated out, partly by centrifugal force and partly by gravity. Air
and finer particles then pass through the double filter system where separation is made. The machine is designed
for filter cleaning by reverse air pulse.
The separated dust accumulates in the cyclone until the machine is switched off, when it drops through the
bottom flap into the plastic bag. The filter cleaning process is not completed before it is clear that the dust inside
the tank has fallen down into the collection bag. In some extreme cases the adhesive ability of the dust must be
broken manually. This can be done by hitting the dust through the bag or tapping the tank using i.e. a rubber
Automatic start function:
When you use the dust extractor together with another machine, there is an
electrical outlet on the dust extractor. Connect the machine to this outlet. Then when you start it up the dust
extractor will also start after 5orms55. 1-2 seconds. When you turn it off, the dust extractor will continue to run
for approximately 10 seconds. To empty the hose. Then stop


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.
