Operating Instructions and Parts Manual
HVLP Paint Sprayers
Maintenance
necessary to remove the tip/nozzle
and needle for cleaning, the
following procedure should be used:
a. Unscrew the material flow knob.
Remove the needle spring, and
then withdraw the needle.
b. Remove the tip.
c. Clean both tip and needle using
cleaner or water and a brush.
d. Reassemble all parts, making sure
that all washers and gaskets are
replaced correctly.
e. Oil the needle spring and put a
spot of oil on the gland seal to
prevent the needle from sticking.
To adjust the gland nut, tighten
until needle sticks, and then
slacken off by about 1/8 turn.
f. Check the cup top gasket and
replace if damaged. Always seat
the cup top gasket flat in the cup
groove. Failure to do this will
allow the cup to drip and impair
the spray pattern due to loss of
pressure.
g. Lubricate all threads to ensure
smooth operation.
Blockages and or leaks may occur if the
gun is left on its side or turned upside
down. Always hang the gun by the
hook when not in use.
