Operation

Read, understand and follow all
quality of finish depends considerably on how well prepared the surface is for painting.
Properly prepare the surface before painting. • You must remove any air from the unit before spraying. This
operation is known as "priming" or "bleeding". If the system is not properly primed, a poor quality paint finish
may result. If the machine constantly starts and stops during use, repeat priming procedure steps 3 to 6.
