The air flow and pressure can be adjusted steplessly using the rotary
l
knob. The blower unit can thus be adapted to the material to be sprayed.
The spray consistency of the material must be determined beforehand in
order to select the best possible settings for the blower and spray gun. A
measuring dip container is supplied with the spray unit for this purpose;
see operating instructins for the PN 2 spray gun for further details. It is
recommended to spray samples before work is started (e.g. onto card-
board or wood). Only when the desired results have been obtained in this
way should you start to spray the object to be painted.
Ensure that the edges or borders of the object to be sprayed are
l
properly masked.
