Nozzle Pipe Assembly - Hardi NAVIGATOR VPZ Instruction Book

Reassemble Nozzle Holder
1. Lubricate the O-ring all the way around using a silicone lubricant.
2. Place the O-ring inside the lower part.
3. Place the lower part on the nozzle pipe, so that the O-ring fits
around the hole in the nozzle pipe, where the spray liquid exits to
the nozzle holder.
4. Place the upper part on the opposite side of the nozzle pipe.
5. Press the parts together until they interlock.
6. Insert the locking piece in the upper part to secure it on the spray
boom.

Nozzle Pipe Assembly

If fluid leaks occur from the pipelines on the spray boom, it is necessary to check the sealing. The pipe fitting need to be
disassembled to locate the O-ring/gasket.
Occasional maintenance of the O-rings/gaskets and pipe assemblies is recommended.
Poor sealing are usually caused by:
• Missing O-ring or gasket.
• Damaged or incorrectly seated O-rings.
• Dry or deformed O-rings or gaskets.
• Foreign objects.
In Case of Leaks
DO NOT overtighten the union nut. Instead disassemble the pipe fitting and check condition of the O-ring/gasket. Replace
if damaged or cracked.
Fitting Types
There are two sizes of boom pipes in use, Ø22 mm and Ø25 mm. They share the same union nut, t-pieces, etc. However, they
differ in the following components:
W. Gasket for 22 mm pipes (part no. 24266200).
X. O-ring for 25 mm pipes (part no. 24263000).
Y. Lock ring Ø22 mm (part no. 33523300).
Z. Lock ring Ø25 mm (part no. 33515500).
