ULV NOZZLE ASSEMBLY
The design of ULV Nozzles is such that it should require little maintenance if the
machine is properly flushed after each use. However, if it becomes necessary to
clean the entire Nozzle Assembly, refer to steps 1-7. To inspect the inside of the
Nozzle it is not necessary to remove the entire Nozzle Assembly from the machine.
Refer to steps 4-7.
TO REMOVE THE ENTIRE NOZZLE:
1.) Loosen the plastic nut on the rear of the nozzle to enable removing the
plastic elbow from the spray tube.
2.) Loosen the steel nut on the rear of the nozzle that secures the nozzle to the
nozzle boom. There are two O-rings within the nut used for sealing against
the spray tube.
3.) Remove nut used to tighten the stainless clamp for retaining the nozzle to the
boom assembly. Remove the stainless steel clamp. The nozzle should now
be free from the boom assembly.
4.) Remove the (3) front plate mounting screws and remove the front plate.
5.) If necessary, the large O-ring installed beneath the front plate can be
removed. NOTE: DO NOT loosen the jam nut that locks the spray tube to the
nozzle cone. See “IMPORTANT” bellow.
6.) Soak the nozzle parts in a degreasing solution to remove all residue.
7.) Thoroughly rinse the parts and reassemble.
IMPORTANT
If for any reason it becomes necessary to have to remove the spray tube from the
nozzle cone, care must be taken to hold dimension “A” when reassembling.
Dimension “A” is the distance from the end of the spray tube to the front face of the
nozzle cone. Be careful not to damage the output end of the spray tube when
disassembling. Note what dimension “A” measures before disassembling nozzle.
