SAFETY INSTRUCTIONS
Handling
•
Cables damaged through crushing or cracking can be dangerous if used and
should be replaced immediately. Risk of personal injury.
•Do not connect the machine to an unearthed socket. Risk of personal injury.
•
Make sure that the foundation is solid so the Bona DCS 70 doesn’t tip over.
Risk of personal injury and property damage.
•
Risk of pinch injuries when handling the toggle fasteners, cleaning unit and
cyclone.
•
Do not vacuum burning or smoldering particles as the machine can catch fire.
If a fire should break out, pull out the plug from the socket and extinguish
using the available firefighting equipment.
•
The machine must not be used in environments where explosive gas can
occur. Large risk for explosions.
•
Do not look into the suction pipe or suction hose if blocked. Large risk of
injury to the eyes.
•
Do not point the suction hose towards body parts when the machine is
running.
Avoid placing your hand or other parts of the body against the suction inlet if
the suction hose is not fitted. Risk of personal injury.
•Do not vacuum water, oil or any other liquids.
•
While lifting the machine, make sure that the dust container is emptied and
that no person is under the lifted machine. Risk of person injury and property
damage.
Service
•
Remove the plug from the wall socket when carrying out maintenance work.
Reassemble all guards on the motor and fan components once servicing is
complete. Risk for person injury.
•
Health impairing dust can be spread when cleaning the coarse filter and
during filter and bag replacement. Accordingly, the user should wear tight
fitting clothing, protective glasses, protective gloves and a breathing mask
conforming to protection class P2.
•
Do not make holes in any filter. Risk of dust dispersion.

Handling
Connect the power cable to the right wall outlet. Assemble the hose to the sanding machine or to the
suction pipe together with the floor nozzle. Start the Bona DCS70 by using the push switch.
The dust extractor separates material in three stages:
•The first stage consists of a cyclone separator, where all coarse material is separated before
reaching a filter.
•The second stage consists of a folded coarse filter that filters out the fine visible dust.
•The third stage, final filtering, uses a HEPA13 filter, which separates the health-impairing dust
which is not visible to the eye.
Coarse filter characteristics
The coarse filter is strong and very stable. Low pressure drop with extremely good separation.
In order to attain maximum capacity from the dust extractor it is important that the filter is cleaned, look
at “Cleaning the coarse filter”, or replaced as soon as the suction effect starts to drop. It is
recommended to change the filter 2 – 3 times per year.
HEPA13 filters operating characteristics
The Hepa13 filter is dimensioned for fine, dry dust and should be preceded by a pre-filter
Caution
•HEPA13 filter cannot be cleaned and must be replaced when spent.
Caution
•The operating stability of the HEPA13 filter drop and can be completely destroyed if exposed to
water.
Caution
•It is recommended to change the HEPA filter 1 – 2 times per year.
Motor and vacuum pump
The dust extractor is equipped with a 1 phase motor with a direct mounted vacuum pump.
The motor is cooled by a separate cooling fan
Auto start function
Start button: 0: Machine OFF
I: Machine ON
II: Auto start function
There is an outlet on the Bona DCS70 which can be used when running a sanding machine. If the
start button is set to 2, the DCS70 will start automatically when starting the connected machine. When
the connected machine is turned off the DCS70 will run for about 10 seconds this to make sure that all
dust in the hose will disappear.

Collection
Particles and dust falls down into a transparent dust container under the cyclone separator.
Inside the dust container is a Longopac bag hose system which should be replaced when full.
The system consists of an approximately 20 mlong plastic hose, which gives about 20 dust free bag
changes.
1. Seal the bag with two
cable ties.
2. Cut between the
cable ties.
3. Pull out a new bag from the
Longopac.

effortlessly cleans the coarse filter.
1. Start the machine
Start button is
set to “I”
(Machine ON)
2. Block the suction hose
by the work place. Wait
about 7-10 sec. while the
machine builds up a
vacuum.
3. Press the filter cleaning valve hard
Repeat the whole process 3 times.
N.B. Clean the filter every time youstart and before you stop the machine.
Replacing the coarse filter
1. Open the cyclone lid 2. Remove the lid
3.
Replace the coarse filter and
place the old filter in a plastic
bag
Replacing the HEPA13 filter
1. Remove lid
2. Loosen the nuts
3. Remove filter
in a plastic bag
4. Seal the bag
and place a new
filter
5.
Place the
HEPA
filter
in
a plastic bag
to
prevent
harmful
particles
spread into the
environment!
Warning

Trouble shooting
The machine is constructed and adjusted to a demanding environment and task, but the user may
notice that the machine contains precision made components which should be protected against hard
blows and jolts. Filter, seals, fasteners and connections are thoroughly adjusted and chosen for the
operators working environment. That is why it is of great importance that the operator and service
personnel treat the machine with insight and knowledge in order for the machine to work perfectly for
its purpose.

Manometer function
Bona DCS70 is equipped with a manometer for monitoring the filter conditions. The meter is checking
the machines filter status but it will also react on outside added hoses etc. Due to this the machine will
respond to the total load. This will not affect the function of the machine with added load. This means
that the meter will be allowed into the red area as shown below.
