Adjusting the spray gas
Spray gas flow is controlled by a gas pressure regulator, factory
adjusted to 1.0 bar. It may be suitable to increase this pressure to
achieve better spray quality when using highly viscous liquids.
Procedure:
Turn the spray pressure regulator (1) clockwise to increase
pressure. The pressure can be read from an external gauge you
can attach at (2). Adjust pressure to 1.5 bar.
