Bona DCS 70
The Bona DCS 70 is a revolution for your working environment. The World Health
Organisation in Vol. 2 of their Evaluation of carcinogenic risks to humans, 1997, notes:
Wood dust is carcinogenic to humans.
Use the Bona DCS 70 for sanding without dust. The two-step cyclonic separation and
the unique filter design of the DCS allow sanding dust to be collected easily and
effectively. This significantly reduces the risk of dust contamination ensuring a cleaner
safer working environment. It is portable so you can take it anywhere on the job site
and connect the hose to your sanding machine. For your customer there are the
benefits of a reduced health risk from sanding dust together with less chance of dust
contamination affecting the property or the finished floor surface.
Healthier working conditions – in compliance with strict European regulations.
Totally sealed system – a unique seamless bag system, so no dust can escape
No more becoming covered in dust when emptying the dust bag
Greater customer satisfaction because of sanding without dust
Unique separation process
Longer working time due to 70 Lt dust bag capacity
Ergonomic – designed for easy use and transport.
Made for professional use – a robust, high quality machine for flooring contractors

For further more detailed technical data please see the machine manual.
When using the Bona DCS 70 for the first time, read the machine manual carefully and
follow the instructions to set the machine up.
Connect the vacuum hose to the DCS 70 and the other end to the sanding machine
using the appropriate connector. Make sure the hose is tightened firmly to the
connector and connect to the sanding machine.
Undo the straps and open the upper part of the DCS 70 by tilting the filter container
backwards. Check that the Longopac ‘endless bag’ cassette is in place and fitted
tightly within the housing. Look for holes or damage in the plastic dust bag and ensure
that the cable ties are tight.
Close and lock the upper part part of the DCS 70 before commencing work..
Connect the cable to the power socket. For your own safety always use an earth
leakage circuit breaker.

Directions for use
Start the DCS 70 by pushing the main switch to position 1. This assumes that the
sanding machine being used is connected directly to a wall mounted power socket.
It is possible to connect a Bona Edger or FlexiSand to the power socket on the side of
the DCS70 although a power cable with a European mainland plug is required. This
allows the ‘Autostart’ function to be used. The main switch should in this case be set
to position 2. The DCS 70 is in standby mode at this point and will start automatically
after a second or two when the sander starts. When you turn the sander off, the DCS
70 will run for an additional 18 seconds to allow the sander to stop completely and
empty the hose.
It is not recommended to use a belt sander with the ‘Autostart’ function as it is possible
that the machine will draw too much power and thus may blow the fuses in the plug or
trip the overload switch in the property’s fuse board.
Cleaning the filter
When the DCS 70 is working correctly, with dust tube connected, the needle of the
‘vacuum gauge’ will be in a vertical (12 o’ clock) position. This is normal.
When the vacuum meter’s needle moves well into the red area, it is time to clean the
filter. Ideally the filter should be cleaned every time you change abrasives on your
sanding machine. Certainly it is better that the filter is cleared too often, than too little.
Disconnect the hose from the sanding machine. Place the ‘open’ end of the hose
against the bodywork containing the coarse filter at the top of the DCS 70. Turn on the
machine so that the DCS 70 attempts to draw air through the hose. Look at the
vacuum meter indicator needle. When it does not move anymore, give the filter
cleaning lever a strong push downwards. Repeat this 4 – 5 times. Reconnect the
hose and continue to sand.
Dust collection
When you have finished sanding or the dust bag is full, the bag must be changed.
Sanding dust, particularly where the timber flooring had been previously coated with
solvent based products or oils, may spontaneously combust. Do not store the DCS 70
or any sanding machine with an un-emptied dust bag. All sanding dust removed from
the machine must be kept outdoors due to the potential fire hazard.
Switch off the machine, leaving the hose attached. Undo the straps and open the
upper part of the DCS 70 by tilting the filter containing section backwards. When it is
fully open gently tap the bag to ensure that any dust on the sides falls to the bottom.
Pick a point near the top and squeeze the bag together to form a cinch point. Place
two cable ties around the cinched bag, approx. 50 mm apart, and tighten them by
pulling firmly. Using the scissors provided cut the bag between the ties.
Pull out approximately ½ metre of the new bag inside the body of the DCS 70. The
vacuum inside the barrel will pull the rest of the bag out into position when the machine
is turned on again.
Periodic maintenance
In general, routine maintenance of the DCS 70 requires simply that it is kept clean from
dust. It is important that the gasket around the Longopac is both in good condition and
in the correct position. When the Longopac is replaced, the location of the gasket is
vitally important as incorrect positioning may lead to dust being able to pass into the
HEPA filter. The condition of the filters must be monitored and when required these
must be replaced.

Outside of the routine maintenance tasks, major servicing of the DCS 70 should be
carried out by a professional machine / electrical workshop.
