Next step, in case the hoses are OK, is to check the filters above the tanks are not wet. These kind of
filters when get in contact with a liquid or if they have some type of particle block loose their
permeability.
If you find any dirt or debris inside of the filters,replace them.
The next step if the problem persists is to clean the suction duct of the applicators. For this purpose
use the cleaning syringe and a container full of warm water (cold also possible).
It is necessary for safety reasons, protecting the vacuum pump in case a treatment is started by
mistake.
To start the cleaning process, insert the blue syringe tube into the suction inlet of the hand piece.
