Applications
BONA DCS25 is a vacuum cleaner in accordance with DS/EN
60335-2-2 and CEI/IEC 60335-2-69 Annex AA class H and
may only be used as such.
BONA DCS25 may be used for collection of dust hazardous to
health according to CEI/IEC 60335-2-69 Annex AA dust class.
BONA DCS25 may not be used for collection of uids or moist
dust.
BONA DCS25 may not be used for collection of ammable,
explosive, poisonous or other dust, uids or gasses hazardous
to health.
BONA DCS25 may only be used in dry environments and
may not be used or stored outdoors or indoors under wet
conditions.
The capacity of a vacuum cleaner to suck vacuum depends
on the air. Theoretically, the suction capacity will fall when the
vacuum cleaner is used at altitudes. The suction capacity of
the vacuum cleaner will be constant from 0 to approx. 800
m above sea level. From 800 to 2000 m the suction capacity
will theoretically fall to approx. 75%. It is not recommended to
use the vacuum cleaner at more than 2000 m above sea level,
as the cooling and the suction capacity will be considerably
reduced.
BONA DCS25 is designed as a handy and compact industrial vacuum cleaner for collection of fine dust and dust
hazardous to health.
The motor top is equipped with suction motor, an integrated handle, switches for the suction
motor and the built-in automatic start-/stop.

Mode of Operation
When the suction motor of the machine is on, the air will be led
through the machine and will collect the dust particles near the
nozzle mounted.
The dust particles will be sucked through the hose into the
collection container, where the majority of the particles will
be held back in the collection bag and/or the pre-lter /
membrane lter.
The air ow and the remaining particles, which have not been
held back inside the collection bag or the pre-lter / membrane
lter, will be carried forward to the HEPA lter.
From the HEPA lter the puried air ow will continue through
the suction pump (blow through) and will be led out of the
vacuum cleaner through the exhaust and noise reduction
lters.
IMPORTANT!
As the motor leads the cooling air through the machine,
all filters MUST be mounted and intact
IMPORTANT!
Never cover up the motor top when the machine is in use.

Assembling
Starting the BONA DCS25 and Collecting Dry Dust
• Unpack BONA DCS25 and check that all the ordered parts
are there.
• Unpack BONA DCS25 and check that all the ordered parts
are there.
• Make sure that the collection container is empty, and that
the pre-lter / membrane lter is correctly tted into the
motor top. Check that the lters of the machine are intact
and undamaged (see the chapter:“Change of Filter”)
• Check that a collection bag is mounted in the container.
• Before the plug is connected to the electrical main
supply you must make sure that the plug and the cord
are undamaged. If the cord or the plug is damaged, a
professional must replace the parts. Only an original cord
may be mounted.
When the machine has been correctly assembled and
connected, it can be switched on and off at the red start/stop
switch of the motor top. The machine has been equipped with
an acoustic and a visual alarm indicating when the air ow is
too low for collection.
BONA DCS25 is equipped with an automatic start/stop and electrical outlet. If you
connect electrical hand tools directly to the power outlet of the motor top, the BONA
DCS25 will automatically be switched on and off when the hand tools are switched on
and off.
The automatic start/stop is programmed with a post-suction cycle. Therefore, the
suction will continue for some seconds after the tool has been switched off.
The electrical tool is connected to the electrical outlet at the back of the motor top.
• Connect the machine to 230 V power supply with a reliable
earth connection.
• Remember to place the label onto the H-label, if the
language of the user is not German.
• BONA DCS25 is now ready for use. The collection is
described in details in the following chapter.
This alarm has to be checked before use: Block the intake at
the end of the hose, and the machine will start beeping, and
the LED will ash. Unblock, and the alarm will stop.

Starting the BONA DCS25 and Collecting Dry Dust
NOTE:
If hand tool with a power consumption of more than 1500 W is
connected, the total current consumption will exceed approx.
13 A, which is often the normal fuse size.
ALWAYS turn off the hand tool before you turn off the machine on the switch.
Automatic start/stop “O” = the automatic start/stop is not activated. The vacuum cleaner will start when you set the main switch
(red) on “I”.
Automatic start/stop “O” = the automatic start/stop is not activated. The vacuum cleaner will start when you set the main switch
(red) on “I”.
When the automatic start/stop is activated “I” and a hand tool is connected to the electrical outlet, the machine will start when
the hand tool is started.
BONA DCS25 can be used with tools with a power
consumption of 2000 W (Country code EU). 1450 W
corresponds to a current consumption of approx. 6,3A.
Information can be found on the data plate of the
machine.
The automatic start/stop is activated with the black switch on the motor top. When
the automatic start/stop is activated, the machine will not start when you push the
red switch. The machine will not start until the connected hand tool is started.
Set the red switch on “I” to start the vacuum cleaner (when “Automatic” is not
needed or no tool connected).

Starting the BONA DCS25 and Collecting Dry Dust
1. Block the intake / Block the hose.
Take hold of the ap of the shock valve.
2. While the machine is blocked and running, pull the ap of the
shock valve (do not tug the valve).
3. When the power grows bigger than the inuence from the
vacuum, the valve will automatically open with a “puff”. Let go
of the valve.
Cleaning the Pre-Filter / Membrane Filter during Operation (as needed, or when the alarm beeps)
Block the intake / hose so that full vacuum is made in the machine.
Repeat the steps 1-3 approx. 2-3 times when cleaning.
The difference in pressure / the shock effect will clean the
surface of the lter, when air is drawn through the valve in
order to equalize the negative pressure in the collection
container and the hose, and will reject possible deposits from
the pre-lter and release collected media from the inside
surface of the collection bag.
This method gives an effective cleaning of the pre-lter /
membrane lter.
We recommend to always leave the machine for a few
minutes before emptying it. The dust will fall to the bottom
of the collection bag, and the risk of swirling dust into the
surroundings during the emptying is reduced.
If – by mistake – the machine has been used without collection
bag, use PPE when emptying the machine.
NOTE:
Do not ”tap” on the intake as this will swirl up the dust in the
container and result in blocking of the pre-lter and damaging
the collection bag.

Cleaning and Maintenance
Read the chapter about safety precautions before cleaning and maintenance.
The easiest way to clean the machine is as follows:
• The Pre-lter is cleaned as required.
• Wipe the machine on the outside with a dry or damp cloth.
The motor top is made of maintenance-free parts and
therefore needs no daily maintenance, apart from external
cleaning and check that the cords and plugs are undamaged.
The easiest way to clean the motor top is with a damp cloth.
Do not aim jets of water directly at the motor top.
In order to avoid stop in operation and also to make sure that
the safety of the vacuum cleaner is intact, it is recommended
that the electrical parts are inspected annually by an
authorized technician.
It is recommended to have an authorized service centre
inspect the motor bushings of the brushes after approx. 800
working hours, and if necessary, replace them. In this way the
life of the suction motor is prolonged.
If the brushes are not replaced before being completely
worn out, the motor may seize up, and this may require a
replacement of the motor.
Check / maintenance of the machine
The machine must always be emptied after use. If the
machine is left with dust, there is a risk of self-ignition.
Reordering of filters and service parts
IMPORTANT!
The machine must not be connected to the
power supply during service and cleaning.
