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
according to the following procedure.
To restart after running out of fuel, turn the switch to the
“ON” position for 15-30 seconds. Try again, if needed. 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 gasoline.
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 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 33.
Replacing Oil Filter
Detach the oil filter by loosening center bolt and remove
the element together with the filter body.
Apply a film of oil to the gasket for the cartridge.
Install the filter body together with the element and fix
them by tightening the center bolt.
After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check
for leaks before adding more oil if needed. Clean
excessive oil from engine.
Replacing Fuel Filter
Replace the fuel filter cartridge with new one every 400
hours or so.
Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.
Vent any air.
Feed Pump Strainer Cleaning
The strainer is incorporated in the feed pump inlet side joint
bolt. Clean the strainer with compressed air and rinse it in
the fuel oil.
