Hyundai HP6700LN User Manual page 41

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 may result.
• 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.
Wear suitable PPE, suggested but not limited to
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 is important
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.
