NOTICE
If a fuel injector is suspected of operating outside of
normal parameters it should be removed by a quali
fi
ed
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.
