Cleaning the spray arms
Waste particles can lodge in the spray arm nozzles.
It is therefore important to inspect the spray arms daily.
The spray arms of the machine, some mobile units, and modules are
labeled as follows:
- M1 = Bottom machine spray arm
- M2 = Top machine spray arm
- A1 = A 501, A 504 mobile unit spray arms
- A2 = A 603 module spray arm
Note the label on the spray arms when you reinsert these into the
machine, mobile units, and modules.
Use a sharp pointed object to push visible particles into the spray
arm nozzles and rinse well under running water.
