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 H.
BONA DCS25 may not be used for collection of fluids or moist dust.
BONA DCS25 may not be used for collection of flammable, explosive, poisonous or other dust, fluids 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.
Description of the Main Parts
BONA DCS25 is designed as a handy and compact industrial vacuum cleaner for collection of fine dust and dust
hazardous to health.
Motor Top with Suction Motor and HEPA Filter
The motor top is equipped with suction motor, an integrated handle, switches for the
suction motor and the built-in automatic start-/stop.
The powerful suction motor of BONA DCS25 is placed in the motor top.

Manual
BONA DCS25 Vacuum Cleaner 13 BONA AB
The motor top is fitted with a HEPA filter in dust class ”H”.
The filter blocks the fine and smallest dust particles, which have not been held back
by the membrane filter. The filter holds back the particles larger than 0.3 m (0.0003
mm). Filter surface : 1.1 m².
To get to the HEPA filter, the pre-filter / membrane filter must be removed.
Motor Top with Alarm and Shock Valve
The motor top is equipped with a shock valve for cleaning the pre-filter, and
an acoustic alarm, which will beep when the air flow is too low (<20 m/sec).
Furthermore, the control panel has a red LED lamp which will visually indicate
when the alarm sounds.
Electrical hand tools can be connected directly to the BONA DCS25.
(MAX 2000 W)

Manual
BONA DCS25 Vacuum Cleaner 14 BONA AB
Collection Container and Collection Bag
The collection container is equipped with a telescopic steering handle and 2
swivel wheels.
The collection container contains the collection bag where the material is
collected, which facilitates the emptying and disposal of the material collected.
The collection bag cannot be filled entirely when very fine dust is collected (eg.
cement, stone grinding etc.).
When collecting dust hazardous to health you must pay attention to the
requirements as to disposal of the collected material. (Closed container; plastic
bag or container). The demands as to packing of the material collected may vary.
Adjustment of the Telescopic handle
To use the telescopic handle –pull and turn to release the position
bolts on the rear side of the frame. The handle can be adjusted –
pulling up-wards or pushing down-wards.
To lock the position bolt, and lever –turn the bolt-head until it “clicks”

Open Locked

Manual
BONA DCS25 Vacuum Cleaner 15 BONA AB
Mounting the Collection Bag
The collection bag is easily mounted into the bag holder by pushing the flange of the collection bag into the slot of
the bag holder.
IMPORTANT!
DO NOT USE THE VACUUM CLEANER WITHOUT COLLECTION BAG

Manual
BONA DCS25 Vacuum Cleaner 16 BONA AB
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-filter / membrane filter.
The air flow and the remaining particles, which have not been held back inside the collection bag or the pre-filter /
membrane filter, will be carried forward to the HEPA filter.
From the HEPA filter the purified air flow will continue through the suction pump (blow through) and will be led out
of the vacuum cleaner through the exhaust and noise reduction filters.
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.
IMPORTANT! Never collect warm or glowing materials.
IMPORTANT! Never extract from processes producing sparks.

Manual
BONA DCS25 Vacuum Cleaner 17 BONA AB
Assembling
•Check that the packing is intact and has no sign of damage from handling and transport.
•Unpack BONA DCS25 and check that all the ordered parts are there.
•Make sure that the collection container is empty, and that the pre-filter / membrane filter is correctly fitted
into the motor top. Check that the filters 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.
•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.
Starting the BONA DCS25 and Collecting Dry Dust
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 flow is too low for collection.
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 flash. Unblock, and the alarm will stop.
Electrical Outlet with Automatic Start/Stop
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.
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

Manual
BONA DCS25 Vacuum Cleaner 18 BONA AB
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.
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).
Automatic start/stop “I”= the automatic start/stop is activated. The vacuum cleaner will start when you use the
hand tool.
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.
ALWAYS turn off the hand tool before you turn off the machine on the switch.

Manual
BONA DCS25 Vacuum Cleaner 19 BONA AB
Cleaning the 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 filter, 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-filter and release collected media from the inside surface of the collection bag.
This method gives an effective cleaning of the pre-filter / membrane filter.
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-
filter and damaging the collection bag.
1.
Block the intake / Block the
hose.
Take hold of the flap of the
shock valve.
2.
While the machine is blocked
and running, pull the flap of the
shock valve (do not tug the
valve).
3.
When the power grows bigger
than the influence from the
vacuum, the valve will
automatically open with a
“puff”. Let go of the valve.

Manual
BONA DCS25 Vacuum Cleaner 20 BONA AB
