Fuel is usually classified according to pour point.
Table 6.1.
Fuel Recommendation
Keep dust and dirt away from the fuel.
While filling fuel in the fuel tank ,avoid getting dirt and
water in the fuel tank , otherwise ,critical injection
pump and injector problems can occur.
Warning
• Fill the fuel tank in well ventilated area and after the
engine completely stopped.
• DO NOT allow any open flame, spark, heat, or lit
cigarette in the areas where the fuel is stored or filled.
• Don’t overfill the fuel tank, be sure to screw the fuel
tank cap on firmly after refueling,
• Be careful not to spill fuel when refueling. If any fuel
is spilled, make sure the area is dry before starting the
engine,
6.2. Filling and checking oil
Warning
• Always check the oil level before starting the engine,
add oil if necessary.
• Oil level should be near to the “H” mark.
• Never run the engine If the oil level is low or very
high, engine damage could occur.
• Chose the proper oil, it is very important to choose
proper oil for Gensets durability and good perfor-
mance. Use of other than the specified lube oil may
cause inner parts seizure or early wear ,leading to
shorten the engine service life.
• The first oil change should be applied within the 20-
25 running hour.
• Aksa recommends API CC/CD classified oil.
• Select the viscosity number according to ambient
temp.

6.3. Filling and Checking Engine Cooling Water
Engine cooling water have to be clean ,soft and have
no corrosive substance . PH value of the coolant
should be between 8,5-10,5.use the specified ethyl-
ene glycol-water antifreeze mixture. Mix the antifreeze
with low mineral drinking water or distilled water. En-
gine cooling water must include antifreeze according
to coolest weather conditions in the area. a mixture
of 50% antifreeze and 50 % water provides a good
protection in all areas.
Remove the radiator cap ,pour the cooling water gen-
tly into the filler port ,take care not to cause bubbling
until it overflows, otherwise the air in the coolant could
cause overheating problem.
6.4. Checking Generator Set
Keep canopy doors closed , while engine is running.
Do the maintenance after the engine is completely
stopped. Check the radiator coolant level, be careful
radiator could be hot.
Be careful of the hot radiator. it’s very dangerous to
open the radiator cap when cooling water is very hot.
The vapour and splashed water may scald you seri-
ously.
Check the battery electrolyte level for maintenance
type battery. Add distilled water, if necessary, so as to
be 1 cm higher than the separation.
Check the grounding protection.
Check the water leakage and oil leakage
Make sure that load doesn’t exceed the power capac-
ity of the unit.
Make sure that the size of the cables is sufficient for
