FUEL SYSTEM SERVICE
At the end of each day, refill the fuel tank to minimize
moisture condensation and dirt contamination in the
fuel line. Do not overfill; leave room for expansion
Use only fresh, No. 2 grade DIESEL fuel. Do not use
kerosene. See the Engine Operatorʼs Manual for
instructions on replacing the fuel filter.
BLEEDING THE FUEL SYSTEM
You may need to bleed air from the fuel system if the
fuel filter or fuel lines have been detached, the fuel tank
has been run empty or after periods of long storage. It
is recommended that the fuel shutoff valve be closed
during periods of non-use.
(For Code 10926, 11121 )
The Kubota D722 engine supplied with this welder is
equipped with an automatic bleeding mechanism that
functions when the electric fuel pump is actuated. It is
generally not necessary to open a vent screw or fuel
line fitting to bleed the fuel system.
(For Code 11888, 11275 )
The Kubota D722 engine supplied with this welder is
equipped with an automatic bleeding mechanism that
helps purge the air from the mechanical fuel pump sys-
tem. It is generally not necessary to open a vent screw
or fuel line fitting to bleed the fuel system. Operate the
priming lever on the pump to assist starting and after
extended periods of non-use or out of fuel conditions.
To avoid personal injury, do not bleed a hot engine.
This could cause fuel to spill onto a hot exhaust
manifold, creating a danger of fire.
