Preparing a New Sprayer
If this unit is new, it is shipped with test fluid in 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.
1. Place the siphon tube into a container of mineral spirits.
2. Place the bleed hose into a metal waste container.
3. Turn the pressure control knob fully counterclockwise to its
lowest pressure setting (fig 7, 1).
4. Open the hydraulic shut-off valve (2) located on the hydraulic
pressure hose. The handle should be in line with the hose.
5. Open the bleed valve (3) by turning it fully counterclockwise.
