9.
Tighten it by 3/4 to 1 turn with a fuel filter wrench.
CAUTION
If the cartridge is tightened excessively, the screw
may be distorted or the O-ring damaged.
PREVENTING FUEL CONTAMINATION
Most of the fuel contaminations encountered while using
the alternator engine are caused by water and
propagation of microbes.
Improper handling of fuel can lead to contamination.
Propagation of microbes requires water contained in the
fuel. To prevent propagation of microbes, keep the water
as low as possible in the storage tank.
FUEL INJECTION PUMP
•
If the fuel injection pump housing is cracked or
damaged, replace it.
•
Ensure the idle operaion and speed control lever’s
sealing device was not removed.
•
Ensure the idling or speed control lever’s sealing line
is not damaged.
•
Do not modify the fuel injection pump if the sealing
line is damaged. Such modifications will void the
warranty.
•
If the fuel injection pump is found to be damaged, it
should only be repaired by authorised personnel.
•
The adjustment and test of the fuel injection pump
must be conducted using an appropriate tester.
CAUTION
If any parts that contain a seal ring (copper seal ring,
rubber coating seal ring, etc.) are disassembled, then
replace the seal ring with a new one. Failure to do so
may cause leakage in the fuel filter connections
preventing normal functioning.
CLEANING THE FUEL PRE-FILTER
The fuel pre-filter should be cleaned periodically through
disassembly. The fuel pre-filter is mounted individually for
easy maintenance. Open the cover of the pre-filter and
clean the element with compressed air first, and then
rinse it with diesel fuel to remove foreign substances.
AIR BLEEDING IN THE FUEL CIRCUIT
Air must be bled from the fuel system when the fuel filter
or injection pump are replaced, or air has entered the fuel
system due to insufficient fuel.
1.
Loosen the air bleeding plug (B) on the fuel filter.
2.
Operate the priming pump by hand to bleed air inside
the fuel circuit.
