Maintenance
•
Check pump wet-cups fluid level daily, page
16.
•
Do not overtighten packing nut/wet-cup.
Throat u-cup is not adjustable.
•
Generally, flush if you will shutdown for
more than three days. Flush more often if
material is moisture sensitive and humidity
is high in the storage area, or if material
may separate or settle out over time.
•
If using an impingement mix gun, close gun
fluid valves A and B when not spraying.
Doing this will keep the internal parts of the
gun cleaner and prevent crossover. Clean
gun mix chamber ports and check valve
screens regularly. See gun manual.
•
If using an Fusion Air Purge impingement
mix gun, always grease the gun after use
until purge air carries grease mist out the
front of the gun. Use Part No. 117773
Grease. See gun manual 309550.
