The dust extractor is provided with an air pulse cleaning system which increases the life of the filter cartridges.
This system works by use of pressurized air, built up by a belt driven compressor. The air is led through a
water separator to the pulse system.
The conditioned air then passes a control valve which regulates the system pressure, and then builds up
pressure in the pulse tank.
The pressurized air is used to generate a pulse of air which cleans the filters from the inside. With every pulse
of the pulse system all dust and particles are released from the filter surface and end up in the dust hoppers
below the filters, where it travels through the rotating valves to be stored in big bags.
In the case of dust harmful to health, contact the local health and safety authorities, and observe national
regulations in force both during use and disposal.
In addition to the Operating Instructions general and legal regulations regarding accident prevention and
environmental protection must be complied with and indicated!
Such duties may for example relate to the handling of hazardous substances or to the provision and wearing of
personal protection equipment.

Prior to any repair works on the dust collector and its drives, secure the dust collector against
unintentional switching on. Put the dust collector to its safety off position. Also make sure there is
no air pressure on the pulse system. The machine is in a safe condition when it cannot generate any
hazard.
Follow additional operating and maintenance instructions of Original Equipment Manufacturers if
included during your service and maintenance work.
Further is advised:
Store the cleaned and dry machine in a dry and humid free room. Protect the electrical motors from moisture,
heat, dust and shocks.

A vacuum gauge measures the difference between the under pressure above the filters and inner filter house.
This readout indicates the degree of pollution of the filters, with this system you can always keep an eye on
the condition and pollution of the filters inside the dust extractor. It can also help you fine-tune the airflow
when precise adjustment is required for the job.
6.1 When to change the filters?
When the “Pressure Diff” gauge is above 20 cm H2O, the filters are probably clogged.
If the vacuum cleaner loses suction power first try the following before continuing:
1. Check if the blower throttles on the silencers are fully opened.
2. Ensure that the compressor is fully pressurized and then turn it off. Remove all moisture from the
compressed air tank by using the drain valve. Turn on the compressor again until it is fully pressurized
again, now use the air gun to completely empty the pulse tank.
3. Only turn on the compressor, and keep the fan unit turned off. Let the machine pulse for about a half
an hour. This action will clean the filters from the inside.
When the “Pressure Diff” gauge keeps indicating more than 20 cm H2O, the filters probably need to be
exchanged.
Or when the machine still does not perform adequately, the filters probably need to be exchanged.
If the silencers blow out dust, stop the machine immediately!
This means probably that a filter is damaged or not fitted properly inside the filter chamber.
Check the filters and replace if necessary.
When a filter was damaged, has leaked or was mounted incorrect,
it has to be replaced. The compartment above the filters, the
connecting air hoses and the silencer also have to be cleaned
thoroughly.
Continuing work with a broken/leaking filter can cause serious
damage to the machine and is a health hazard!
Never expose the filter cartridges to moisture!
Pressure Diff.
This indicates the pressure difference
between the clean and dirty side of the
filters. To check the status of the filters.

Operators should observe any safety regulations appropriate to the materials being handled.
Warning! Always wear Personal Protective Equipment, the dust can be hazardous to the health!
Make sure you have enough sturdy plastic bags or use big bags for the disposal of the old filters.
Observe the national regulations in force both during exchange and disposal of the old filters.
Remove the filter house door.
Loosen the nut+washer (2).
Remove the locking bar (1).
The filter bracket will now be tilted downwards so the
filters can be taken out easily.
Slide out the filters (3) and put it in a sturdy plastic
bag.
Close the bags properly.
When a filter was damaged, has leaked or was mounted incorrect, it has to be replaced. The compartment
above the filters, the connecting air hoses and the silencer also have to be cleaned thoroughly.
Pull out the mains plug before you start
Always wear gloves and a dust mask of at least class FFP3
Use an extra vacuum cleaner in order to work as dust free as possible
