DCA-15SPX4 — MAINTENANCE
Generator Storage
For longe term storage of the generator the following is
recommended:
Fill the fuel tank completely. Treat with a fuel stabilizer
if necessary.
Completely drain the oil from the crankcase and refill if
necessary with fresh oil.
Clean the entire generator, internal and external.
Cover the generating set and store in a clean, dry place.
Disconnect the battery.
Make sure engine coolant is at proper level.
If generator is mounted on a trailer, jack trailer up and
place on blocks so tires do not touch the ground or block
and completely remove the tires.
Flushing Out Radiator and Replacing Coolant
Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open the
radiator cap while draining. Remove the overflow tank
and drain.
Check hoses for softening and kinks. Check clamps for
signs of leakage.
Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed. DO NOT
clean radiator core with any objects, such as a
screwdriver.
Tighten both cocks and replace the overflow tank.
Replace with coolant as recommended by the engine
manufaturer.
Close radiator cap tightly.
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. See the
KUBOTA
Engine Manual
for details.
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.
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 17.
Replacing Oil Filter
Remove the old oil filter.
Apply a film of oil to the gasket on the new oil filter.
Install the new oil filter.
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.
Allow engine to
cool
when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.
WARNING - BURN HAZARDS
Replacing Fuel Filter
Replace the fuel filter cartridge with new one every 500
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.
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.
