Air Bleeding The Fuel System - Kubota J106-STD Operator's Manual

30 PERIODIC SERVICE
No.2-D is a distillate fuel oil of lower volatility for engines
in industrial and heavy mobile service.
(SAE J313 JUN87)
Grade of Diesel Fuel Oil According to ASTM D975
The cetane number is required not to be less than 45.
A Be sure to use a strainer when filling the fuel tank, or
dirt or sand in the fuel may cause trouble in the fuel
injection pump.
A Always use diesel fuel. You are required not to use
alternative fuel, because its quality is unknown and
affect the generator performance. Kerosene, which is
very low in cetane rating, adversely affects the engine.
Diesel fuel differs in grades depending on the
temperature.
A Be careful not to let the fuel tank become empty, or air
can enter the fuel system, necessitating bleeding
before next engine start.

refitted;
A after the fuel tank has become empty; or
A before the engine is to be used after long storage.
