Pressure Relief Procedure
1. Engage trigger lock.
2. If the system will be shut down for more than a few
hours, perform Park Metering Pump Rods
procedure on page 45 to prevent fluid hardening on
the metering pump shafts.
3. Press the stop button .
4. Slide the feed pump air supply valve (DF) and
director valve air supply valve (DA) to the OFF
position.
5. If necessary to relieve tank air pressure: close both
feed system air control ball valves (CT, CS) and
back out the air pressure regulator (CB). Open the
brass valves on the tank lids for full tank
de-pressurization. Pressure gauge (CR) should
read 0 psi.
Important Safety Instructions
Read all warnings and instructions in this
manual before using the equipment. Save
these instructions.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
FIG. 37: Feed Pump Air Controls
NOTICE
The material may expand when air pressure is
removed. This can cause the tank to overfill and
damage the parts attached to the tank lid. To
prevent overfilling the tank, never relieve air
pressure in the tank unless the tank is less than half
full. Verify tank material level on the user interface,
see Supply Screen, page 83.
