3.2. Check and refill the engine oil.
3.2.1.To ensure the generator maintains an optimum
performance and the life of the generator is as
long as possible, it isimportant to use the
correct engine oil – SAE10W/30 – SAE15W/40
(API CH-4/CF/SJ/SL diesel engine oil or higher
grade) and change after the first 20 hours, then
every 100 hours.
3.2.2. If the correct engine oil is not used, or the engine oil is not replaced every 100
hours, as required, the risk of crankshaft bearing failure, piston seizure, piston
ring sticking and
accelerated wear of the cylinder liner, main bearing and failure of other moving
components increases significantly. The generator lifespan will be greatly reduced if
oil level and oil changes are reduced.
3.2.3. Remove oil filler cap and check engine oil level
3.2.4. If oil level is below the lower level line, refill with SAE API CH-4/CF/SJ/SL diesel
engine oil on dipstick, or to the top of filler neck. N.B. do not screw oil filler in the
oil filler cap when checking oil level.
3.2.5. Change contaminated oil.
3.3. Service the AirCleaner.

Always check the engine oil level with the generator on a flat, level
surface before starting or refilling the machine.
If an insufficient amount of engine oil is used, damage to
the engine mayresult.
Do not overfill the engine with oil.
This generator is equipped with a low oil pressure switch
this system will stop the engine automatically when the oil
pressure falls below the minimum pressure required.
This helps prevents damage such as bearing seizures etc.
However, this should not be relied upon and the engine oil
level should be checked and topped up if required, daily.
Do not wash air filter with detergent.
Replace the air filter if the engine output decreases or
excessive exhaust smoke is noticed.
Never run the generator without the air filter, otherwise
rapid engine wear will result.
