tainer.
6. Remove air cap (1) and cup from gun, then clean each section with brush
soaked with cleaner and wipe out with waste cloth. Do not use metal

5.2 MAINTENANCE
_ Before disassembly, clean fluid passages
a. Disassemble fluid nozzle (10), while keeping fluid needle (11) pulled (trig-
gering) in order to protect its seat section.
b. Disassemble fluid needle set. (only when strictly necessary)
c. Remove the fluid needle adj. knob (17) and needle spring (18), extracting
the spring and fluid needle set (11), from the back of fluid adj. guide set
(7-5) still assembled on the gun body.
d. Adjustment of the needle packing nut (13), must always be carried out
with fluid needle (11) already assembled, tightening the nut with a suita-
ble spanner, making sure that excessive tightening does not impede
movement of fluid needle, resulting in paint leaking from fluid nozzle tip
(10).
e. For the inspection and replacement of air valve components, remove fluid
needle adj. knob (17), fluid needle spring (18) and fluid needle (11), after
which disassemble fluid adjustment guide (7-5) and all air valve compo-
nents in order: air valve spring seat (7-4), air valve spring (7-3) air valve
(7-2).
To reassemble the air valve, reverse the procedure.
f. Disassembly of pattern adjustment set (5) In order to disassemble pattern
adj. set (5), turn the hexagon knob of the adjustment counterclockwise
manually, to open it completely and unscrew the hexagon nut with a span-
ner, turning it counterclockwise.
- To reassemble pattern adjustment set, reverse the procedure.
The fluid passages of the gun, must be cleaned thoroughly
after each use, especially after use with bi-component paints.
Incomplete cleaning can cause defective pattern shape.
