9. TROUBLESHOOTING
Occasionally poor functioning of the machine may
occur. In these instances, one must refrain from using
the machine and provide the necessary maintenance
before incurring accidents or damage.
If the DOBLE 250 machine does not supply liquid to
the atomizer after having been supplied with
compressed air and after having opened the tap, it
may signify that the tubes are blocked.
The same reason can also be valid with regard to the
pneumatic system.
Call the manufacturer for any information or with any
doubts before intervening.
