Flushing  
Pressure Relief Procedure  
Trapped air can cause the pump to cycle unexpectedly,  
which could result in serious injury from splashing or  
moving parts.  
Flush equipment only in a well-ventilated area. Do not  
spray flammable fluids. Do not turn on heaters while  
flushing with flammable solvents.  
1. Select Park on Pump Control Switch if available, or  
Flush out old fluid with new fluid, or flush out old  
fluid with a compatible solvent before introducing  
new fluid.  
turn off.  
2. Turn off feed pumps.  
Use lowest possible pressure when flushing.  
3. Trigger gun to relieve pressure.  
4. Close gun inlet valves.  
To flush entire system, circulate through gun fluid  
manifold (with manifold removed from gun).  
5. Close fluid supply inlet valves.  
Always leave some type of fluid in system. Do not  
use water.  
6. Service spray gun. See corresponding spray gun  
manual.  
Preventive Maintenance  
When pumps are functioning properly, it is not unusual  
for a trace amount of resin to seep past the pump pack-  
ing onto the resin pump shaft. Routinely inspect shaft  
and wipe away any residue when the proportioner is  
turned off. Disassemble and clean the proportioning  
pumps annually. For pumpline P7758-255773, disas-  
semble and clean the proportioning pumps every six  
months. Inspect the pistons and cylinder for marks or  
scratches, which may cause leakage and damage to  
packings. Replace all packings, o-rings, and bushings  
annually. For pumpline P7758-255773, replace these  
items every six months.
