Nozzle Holder Assembly
If leaks of fluid occur in the nozzle holders on the spray boom, it is necessary to check the gaskets. The nozzle holder needs
to be disassembled to locate the gaskets. Occasional maintenance of the gaskets and nozzle holders is recommended.
Poor seals are usually caused by:
•
Missing O-rings
•
Damaged or incorrectly seated O-rings
•
Dry or deformed O-rings
•
Foreign objects.
In Case of Leaks
1.
Disassemble the pipe fitting.
2.
Check condition and position of O-ring. Replace it if damaged or cracked.
3.
Clean and lubricate the O-ring. Lubricate all the way around using a non-mineral lubricant.
4.
Reassemble the O-ring or gasket and pipe fittings. When tightening the fittings, a little mechanical leverage may be
used.
