Start-Up
TOOLS REQUIRED
•
5/16” Spintite (P/N 0904A)
IMPORTANT: Before attempting the following procedures, make sure the gun is
attached to the coupling block and air hoses, the proportioning unit is at the desired
temperature and pressure, and the system is ready for operation.
1.
ADJUST THE AIR VALVE AIR ADJUSTMENT CAP CONTROL- The Knurled
knob on the Air Cylinder controls the amount of air that passes over the PCD. This
flow of air helps keep the PCD free of sprayed chemical. Too much air can
adversely effect spray pattern shape and create undesirable amounts of over-spray.
However, the airflow can be used to modify the spray pattern. Experiment to
determine what works best for the application.
Turn the knob Counter clockwise to open the valve and clockwise to close it.
NOTE:
If the GX-8 is shipped from the
factory without the Mixing Module
and PCD installed the Valving Rod
will require adjustment. See the
Valving Rod Adjustment section of
the manual.
2.
OPEN BOTH MANUAL VALVES- Using the 5/16” Spintite, turn each valve fully
counterclockwise.
3.
DISENGAGE THE SAFETY STOP- Push in and turn the Safety Stop knob
counterclockwise to place the gun in the Open detented position.
4.
TEST SPRAY OFF TARGET
