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.
Max vacuum (0m/s)
Level for need of Filter cleaning
with 38mm hose (25m/s)
