PURGING AND PRIMING
This unit is shipped with test fluid in the fluid section to
prevent corrosion during shipment and storage.
For spraying with solvent-based paint, thorough flushing of
this material is not necessary.
If you are going to spray with LATEX paint, this fluid must
be thoroughly cleaned out of the system.
KEEP SPRAY GUN LOCKED AND IN THE OFF POSI-
TON DURING ALL THESE STEPS.
Purging System for Latex Paint
1. Place a bucket of soapy water under the paint suction
tube. Also, have a waste container handy to catch the
purged fluid.
2. Place paint return hose into the waste container.
Figure 4. Turn Pressure Control Knob Counter-Clockwise to
Reduce Pressure
Figure 3. Place return hose so purged fluid goes into
waste container.
WARNING
If a metal container is used, ground
the gun by holding it against the
edge of the container while flushing (As shown below).
Failure to do so may lead to static electric discharge, which
may cause a fire.
