ADJUST NOZZLE OPENING PRESSURE
76
Close pressure gauge valve and flush nozzle by operating
pump rapidly.
Raise pressure on pump until nozzle opens (gauge drops
sharply).
Refer to nozzle opening pressure specifications below.
NOTE: In a few applications, RE60062 Nozzles (normally
used on aspirated engines), may be specified for
turbocharged (T or H) engines. In these cases,
use specifications listed below for naturally
aspirated (D) engines.
