tion of water or dirt into fuel tank or other portion of

and possible injection pump and injector damage.
IMPORTANT: Do not tamper with injection pump or
injector adjustments as doing so may
render engine and / or Tractor warran-
ty void and may cause severe engine
damage. Consult your ISEKI Dealer.
