the fluid section to prevent corrosion during
shipment and storage. This fluid must be
thoroughly cleaned out of the system with
mineral spirits before you begin spraying.
Attention
Always keep the trigger lock on the spray gun in
the locked position while preparing the system.
Refer to the spray gun instruction manual for
trigger lock instructions.

PREPARING TO SPRAY

Before spraying, it is important to make sure that
the fluid in the system is compatible with the
paint that is going to be used.
Incompatible fluids and paint may cause the
valves to become stuck closed, which would
require disassembly and cleaning of the sprayer’s
fluid section.

Always keep the trigger lock on the spray gun in
the locked position while preparing the system.
Refer to the spray gun instruction manual for
trigger lock instructions.
