11. Disengage gun piston safety lock.

12.Test spray onto cardboard. Adjust for desired fluid pressure on the DN stroke with regulator (AS). Briefly spray until the UP stroke indicator light is on and increase the UP regulator setting until the fluid pressure (GA, GB) matches the DN stroke pressure. This compensates for feed pump pressure boost.
Pumps have fluid to air ratio of 17.5 to 1. Feed 
pumps add 2X feed pressure boost to outlet pressure (on the up stroke only).
13.Check A and B fluid pressure gauges (GA, GB) to ensure proper pressure balance between A and B. If imbalanced, see repair manual 311512.
14.Equipment is ready to spray.
Spraying Setup
Spray Adjustments
Flow rate, atomization, and amount of overspray are affected by four variables.
•Fluid pressure setting. Too little pressure results in an uneven pattern, coarse droplet size, low flow, and poor mixing. Too much pressure results in excessive overspray, high flow rates, difficult control, and excessive wear.
•Fluid temperature. Effects are similar to when fluid pressure setting is too high or too low.
•Mix chamber size. Choice of mix chamber is based on desired flow rate within machine capability and fluid viscosity.
•Cleanoff air adjustment. Too little cleanoff air results in droplets building up on the front of the nozzle, and no pattern containment to control over- spray. Too much cleanoff air results in
