4. Ensure the gas is turned on at the source.
Cauon:
Ensure that the regulator provides gas to the generator at the pressures detailed in the
specicaons for the model being assembled.
Ensure that all connecons are ght and all equipment is within its test dates and is in good
condion and suitable for its intended purpose.

ForbothPetrolandGasOperaons
For cold start
1. Move the choke lever to the “CLOSED” posion.
2. Set the circuit breaker to the “OFF” posion.
3. Set the Engine switch to the “ON” posion.
Manual Start
4. Pull the rip cord to start the engine.
Electric Start
4. Push the engine switch to the “START” posion, once the engine is running release the switch.
5. Once the engine is running smoothly move the choke to the “OPEN” posion.
6. Connect electrical devices to the generator, ensuring that their combined power requirements is less
than or equal to the capacity of the generator (e.g. do not overload the generator).
7. Set the circuit breaker to the “ON” posion.
Shung Down the Generator
1. Set the circuit breaker to the “OFF” posion.
2. Set the engine switch to the “OFF” posion.
3. Close all the fuel stopcocks.
4. Ensure that all gas sources are turned o at their source.
5. Allow the generator to cool prior to moving.
Warning:
* The engine and muer will be very hot aer the engine has been run.
* Avoid touching the engine and muer while they are sll hot with any part of your
body or clothing during inspecon or repair.
* Fuel is highly ammable and poisonous.
* Be careful during refueling.
* Do not ll above the top of the fuel strainer or it may overow when the fuel heats up
later and expands.
* Wipe up any spilled fuel immediately.
* Aer refueling, make sure the tank cap is ghtened securely.

Periodic Maintenance
Regular maintenance is most important for the best performance and safe operaon.
WARNING
Stop the engine before performing any form of maintenance
Maintenance Intervals
Spark Plug Inspecon
1. Remove the spark plug (use the plug wrench provided with the generator at me of purchase.
Check for discoloraon and remove the carbon.
Standard electrode color: Tan color
2. Check the spark plug type and gap.
Standard Spark Plug: NGK(BP6E)
Spark Plug Gap: 0. 7-0.8 mm(0.028-0.031 in)
3. Install the spark plug. Spark Plug Torque: 20 N.m (2 kgf.m, 14 lbf.)

8896231 • 8896322 • 8896324
Engine Oil Replacement
1. Place the machine on a level surface and warm up the engine for several minutes.
Then stop the engine.
2. Place an oil pan under the engine. Remove the oil drain plug so that the oil can be completely drained.
3. Check the drain plug, gasket, oil ller cap and 0-ring. If damaged,replace.
1: Oil drain plug
2: Gasket
3: Oil ller cap
4. Reinstall the oil drain plug.
Drain Plug Torque:
30 Nm (3.0 kgf m,22 lbf )
5. Add engine oil to the specied level.
Recommended oil: SAE #30 or lOW-30
Oil Quanty: 8896231: 600ml, 8896322: 1100ml, 8896324:1300ml
Air Filter Maintenance
1. Remove the air lter cover and element.
2. Wash the element in solvent and dry.
3. Oil the element and squeeze out the excess.
The element should be wet but not dripping.
Recommended oiI:
Foam-air-lter oil or SAE #20 motor oil CAUTION:
Do not wring out the element, this could cause it to tear.
4. Insert the element into the air lter
NOTE:
Be sure the element sealing surface seats into the
air lter housing so there is no air leak.
CAUTION:
The engine should never run without the element;
excessive wear or damage could result.
WARNING
Never use solvent while smoking or in the vicinity of an open ame.

1616
Fuel Filter
1. Turn the fuel cock lever to “CLOSE”.
2. Using a suitable wrench, remove the cap on the underside of the stopcock. (Be careful to ensure that
the small components inside are not lost.)
3. Remove the mesh screen lter from the cap assembly and clean with solvent.
4. Wipe the mesh screen dry.
5. Check the gasket. Replace if found damaged.
6. Reassemble the cap assembly back onto the stopcock. Reassemble it in the same order it was removed.
Fuel Tank Filter
1. Remove the fuel tank cap and lter.
2. Clean the lter with solvent. If damaged, replace.
3. Wipe the lter and reinsert it into the throat of the fuel tank.
Storage and Transportaon
1. Allow the engine to cool completely before storage.
2. Close the manual shuto valve on the LPG cylinder or on the CNG pipeline and disconnect from the
generator set.
3. Store the generator in a dry, well-venlated place. It is best to cover the machine if it will be stored for
long periods.
4. The generator must remain in a vercal posion during transport and storage.
(Engine oil can drain out if not stored/transported vercally resulng in damage.)
