AIRCAP SET SELECTION
The fluid nozzle 6082 and needle 8020 MUST always match exactly. Size
No.4 is standard with all Fuji sprayguns. No. 3 or No. 4 can be used for
any type of fine-finishing application. The difference between the two is that
the #4 allows for more fluid output. This is desirable when spraying fast
drying lacquers. It allows you to spray faster and wetter to obtain better
leveling of the finish. 4 additional setups are available as accessories.
Generally speaking, the quality of atomization and finish reduces as you
go to the larger size setups (No.5 and 6).
If you do not intend on spraying walls & ceilings then the only two
setups you would ever need would be the #3 Fine and Standard #4.

ADJUSTING THE NEEDLE PACKING
The needle packing must be tight enough to prevent any leakage of paint
material. It should however, allow the needle to glide smoothly through it. If
the packing is too loose, you will see a small amount of paint where the
needle passes through the small needle packing nut 8008. Using the supplied
wrench, gently
tighten
the nut. This is a good time to apply a spot of oil to the
needle where it passes through the packing nut. This is a sensitive adjustment
so please adjust only 1 or 2 degrees at a time.
If the needle packing is too tight, paint will spurt out of the fluid nozzle 6082
when you release the trigger. To correct,
loosen
the needle packing nut 8008.
Like all spraygun manufacturers, we use ‘stock’ stainless steel rod for the
needle. This rod can differ in diameter slightly with each production run. So if
you change a No. 3 for a No. 4 needle, one could be a slightly oversized
diameter and one slightly undersized. This may necessitate adjusting the
needle packing.
THE SPINDLE VALVE ASSEMBLY
The spindle valve assembly 9003 can be removed as follows.
1) Remove the fluid knob 8029, spring 8019, and gently pull out
the needle assembly 8020.
2) Turn out the fluid screw nut 8031 (a socket is preferable to a wrench).
3) Remove the spring 8026 and gently pull out the spindle valve
assembly 9003.
To replace, reverse the procedure being careful to center the spring 8026
onto the spindle valve 8021. Also, before tightening in the fluid screw nut
please ensure that the spindle is centered in the seal. The end of the spindle
is visible through the hole in the fluid screw nut.
THE SPINDLE VALVE SEALS
Removal and replacement of the spindle valve seals is simple. Any thin, flat
tool such as a screwdriver can gently pry out the seal. To replace, firmly push
the seal into place. Small leaks of air are not important and will have absolutely
no effect whatsoever on the atomization process.
The seals are designed to be durable and long-lasting under normal work-
ing conditions. We do not recommend the practice of dunking the whole
spraygun into a container of solvent. This may damage the valve and valve
seals.
