Check nozzle with a hand tester (at fuel oil
temperature 20°C [68°F]). Replace the noz-
zle tip if the spray pattern is still bad after
washing in clean fuel oil.
Nozzle valve seat oil

Seat shall hold a test pressure lower than
valve opening pressure by 1.96 MPa
{20 kgf/cm²} [285 psi] for 10 seconds.
Wash in clean fuel oil or replace nozzle tip.
