Accumulator & Filter:
Maintenance:
The accumulator & filter should be disassembled and cleaned approximately once per week
(more often if the weather is hot).
Troubleshooting:
If you must keep increasing pressure to maintain an adequate spray fan, the filter may be
clogged with debris. If the spray is pulsing, the accumulator is probably blocked. When dealing
with system blockages, follow the safety instructions below.
DANGER: Before disassembling accumulator, relieve fluid pressure and air pressure. If
material is plugging the system, some parts of the system may still contain fluids under
high pressure, even after you have followed normal procedures to relieve the pressure.
WARNING: To prevent injury, hold a large rag or shop towel around the wrench and
fitting as you remove the fitting. Remove the fitting slowly to allow fluid pressure to
escape into the rag or towel.
WARNING: Always wear appropriate eye protection and other protective clothing when
performing service and repair on the accumulator & filter.
Parts Drawings:
To service the accumulator, please follow the procedures below, using drawing FF-5000-XX
Accumulator & Filter Assembly.
Relieve Air and Pump Pressure:
1. Turn pump pressure off.
2. Hold the gun over an appropriate empty container and lock the gun in an open position.
3. Disconnect air from the system.
4. Place an empty container under the filter/accumulator; slowly open the ball valve at the
bottom of the filter cap.
DANGER: Never attempt to remove, repair or clean an accumulator until you have
relieved pressure.
