flow:
•
Use the lowest pressure and largest nozzle size that

provides an acceptable spray pattern. This will also
result in seals and wear parts lasting much longer.
•
Do not use any more fluid hose than is necessary.
•
Use an applicator with a rubber tip retainer that will
blow off if it plugs.
Before Starting or Stopping Material Flow
•
Start and stop the fluid flow with the red-handled air

motor pilot valve at the applicator.
•
Always have the atomizing air turned on before and
after spraying fluid.
Before Starting Material Flow
1. Always open the air assist shutoff ball valve (U) and
adjust needle valve for air assist flow control (M)
first.
2. Open (turn on) the air motor pilot ball valve (G) last.
Before Stopping Material Flow
1. Always close (turn off) the air motor pilot ball valve
(G) first.
2. Turn off the air assist shutoff ball valve (U).
Spraying
Do not allow pump to run without material in the hop-
per. It will quickly accelerate to a high speed, causing
pump seal damage.
To prevent material curing in the system, never load
mortar into a dry system. Loading mortar into a dry
system will cause the mortar to stick to internal com-
ponents and cure, causing damage and requiring
replacement of those parts.
