Identification of a suspect Fuel
Injector
Work carefully around an engine that is running.
Engine parts that are hot, or parts that are mov-
ing, can cause personal injury.
NOTICE
If your skin comes into contact with high pressure
fuel, obtain medical assistence immediately.
NOTICE
If a fuel injector is suspected of operating outside of
normal parameters it should be removed by a quali-
fied technician. The suspect fuel injector should be
taken to an authorised agent for inspection.
Operate the engine at a fast idle speed in order to
identify the faulty fuel injector. Individually loosen and
tighten the union nut for the high pressure pipe to
each fuel injector. Do not loosen the union nut more
than half a turn. There will be little effect on the
engine speed when the union nut to the faulty fuel
injector is loosened.
Consult your authorized Perkins dealer or your
Perkins distributor for further assistance.
