2. Using a wrench, turn the fuel filter cartridge to the left
to remove fuel filter.
3. Clean the fuel filter holder.
4. Coat the seal surface of the fuel filter cartridge with
engine oil, then reinstall the fuel filter cartridge back
onto the fuel filter holder.
5. When installing, tighten the fuel filter cartridge until it
makes contact with the seal surface of the filter holder.
Then tighten a further 2/3 of a turn.
If the fuel filter cartridge is tightened too much, the
seal will be damaged and will cause fuel leakage. Fuel
leakage will occur if the filter cartridge is not tightened
enough.
Fuel Addition
When adding diesel fuel, always use low sulfur No. 2 diesel
fuel. Always pour fuel through a mesh filter.

Air Removal
If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel, or
after disassembling the fuel system, bleed the system.
To restart after running out of fuel, squeeze the fuel primer
bulb to pump fuel into the engine. This unit is equipped with
an automatic air bleeding system.
Cleaning the Fuel strainer
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in diesel.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation
or once a month.
Check Oil Level
Check the engine crankcase oil level prior to each use,
or when the fuel tank is filled. Insufficient oil may cause
severe damage to the engine. Make sure the generator is
level. The oil level must be between the two notches on the
dipstick as shown in (Figure 8).
Changing engine Oil (100 Hours)
1. Drain the engine oil when the oil is warm.
2. To drain the engine oil the tub access cover
(Figure 26) must be removed.
