OPENING PRESSURE. Oper
ate tester lever slowly while observing
tester gage reading. Opening pressure
should
be
11720
kPa
(1700 psi)
for all
models. Opening pressure is adjusted by

removing shims
in
shim pack
(8-Fig. 141).

SPRAY PATTERN.
The
spray
pattern should
be
well atomized

then operate tester lever
to
bring gage pressure
to
1035
kPa
(150
psi) below opening pressure
and
hold

for
10 seconds.
If
