3. PREPARATION for STARTING
• DO NOT refill tank while engine is running or HOT.
•Do not smoke or allow flames or sparks in the area where the
engine is refueled or where the fuel is stored.
•Do not overfill the diesel tank and make sure the filler cap is
securely closed after refueling.
•Take care not to spill fuel when refueling. If any fuel is spilled,
make sure the area is clean and dry before starting the engine.
Wear suitable PPE, suggested but not limited too
3.1. Selection and handling of fuel.
3.1.1. Selection of fuel.
3.1.1.1. Only use standard specification diesel, this can be red or white.
3.1.1.2. Keep dust and water out of the fuel.
3.1.1.3. When filling the fuel tank from drums, make sure that no dust or water is
mixed in with the fuel. This can cause serious damage to the fuel injection pump
or the injector nozzle.
3.1.1.4. Do not overfill. Overfilling can potentially be very dangerous. Diesel can
expand in hot weather and overflow
3.1.1.5. Always leave a 25mm gap above the fuel level.
• Always check the engine oil level with the generator on a flat,
level surface before starting or refilling the machine.

Page 9
Rev 2
•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 too
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.
3.3. Service the Air Cleaner.
• 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.
