NOZZLE MAINTENANCE
Nozzle Maintenance
The Whirl-A-Way comes with 25° nozzles that have an orifice size of 020. They are
installed and aligned properly during production. To confirm proper alignment, inspect
the nozzles. The indent line of the nozzle has to be in line with the rotary arm. If they are
out of alignment the resulting spray angle will result in striping with the possibility of the
rotary arm not spinning at all.
If there are any performance issues, including vibration, pulsing, or stripping, then it is very
likely the nozzles are damaged or clogged.

inspection or maintenance.
