- Checking Fuel Pipe
Although checking the fuel pipe connection is
recommended every 100 service hours, it should
be done every 6 months if operation does not
exceed 100 hours in 6 months.
1. If the tightener band is loose, apply a slight coat of
lubricant onto the threads and securely tighten it.
2. The fuel pipe is made of rubber and ages
regardless of period of service. Change the fuel
pipe together with the tightener band every two
years and securely tighten.
3. H o w e v e r, if the fuel pipe and tightener band are
found damaged or deteriorated earlier than two
years, then change them right off .
4. After the fuel pipe and tightener band have been
changed, bleed the fuel system.
I M P O RTANT :
• When the fuel pipe is disconnected for change,
close both ends of the fuel pipe with a piece of
clean cloth or paper to prevent dust and dirt from
entering. Entrance of dust and dirt cause
malfunction of the fuel injection pump. In addition,
particular care must be taken not to
admit dust into the fuel pump.
-Cleaning the Fuel Filter Pot
When period of operation reaches approx. 100
hours, clean the fuel filter.
This job should not be done in the field, but in a
clean place so as to prevent dust entry.
1. Close the fuel filter pot cock.
2. Unscrew and remove the top cap, and rinse the
inside with kerosene.
3. Take out the element and dip it in the kerosene
to rinse.
4. After cleaning, reassemble the fuel filter, keeping
out dust and dirt.
5. Bleed the injection pump.
I M P O RTANT :
• If dust and dirt enter the fuel, the fuel pump and
injection nozzle are subject to quick wear. To
prevent this, be sure to clean the fuel filter pot
p e r i o d i c a l l y.
- Oil Level Check and Refill (See page 44)
1. Check engine oil before starting the engine and
5 minutes or more after the engine has stopped.
2. To check the oil level, draw out the dipstick, wipe
it clean, replace it, and draw it out again. Check
to see that the oil level lies between the two
n o t c h e s .
• Stop the engine when attempting the check
and change prescribed below.
• Never fail to check the fuel pipe periodically.
The fuel pipe is subject to wear and aging,
fuel may leak out onto the running engine,
causing a fire.
