Safety labels

• Maintain all safety labels on the unit clean and readable. If a safety label is no longer readable, have it replaced.

Charging the battery

• The generator has an automatic charging function. The battery emits hydrogen gas while charging, which is a highly explosive gas. Do not smoke while charging the battery.

PREPARING THE GENERATOR FOR USE

Usage of the oil/water separator

• The diesel generator is equipped with an oil/water separator (Fig. 1) which drains off water from the diesel.
• In order to drain off water from diesel, turn the tap of the oil separator counterclockwise.
• Once the water has been drained off, turn the tap of the oil separator clockwise to prevent diesel from leaking.

Checking the oil level

To check the oil level, take the following steps:

1. Verify that the generator is shut down and on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine.
3. With a dry cloth, wipe the oil off of the dipstick that is located on the inside of the cap.
4. Insert the dipstick and then remove it again. There should be oil on the dipstick. If there is no oil on the dipstick, or oil is visible only at the very end of the dipstick, add oil until the engine crankcase is filled.
5. Put the oil filler/dipstick cap back in place.

Changing/adding oil

To drain the oil from the generator, take the following steps:

1. Place a tray underneath the generator to catch oil as it drains.
2. Unscrew the oil drain plug.
3. Allow all the oil to drain from the generator.
4. Put the oil drain plug back in place and tighten it.

To add oil to the engine, take the following steps:

1. Confirm that the generator is on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine.
3. Using a funnel, add high detergent motor oil to fill the engine to the correct quantity.
   When the engine is full, the oil level should reach the lower lip of the oil filling opening.

Check the air filter

1. Unscrew the bolt and take out the side plate.

2. Loosen the clipper to take out the air filter cover and reveal the air filter element.
   • Do not clean the element with detergent.
   • The element should be replaced if the output power drops or if the exhaust gas is black.
   • Do not start the generator without the air cleaner in place. Doing so will cause damage to the generator.

3. After putting the air filter element back in place, fit the cover on top of the air filter and retighten the clipper firmly.

Check the generator

• Before starting the generator, turn off the main switch.
• Ground the generator correctly.

Warning: Failure to properly ground the generator can result in electrocution.

Check the fuel piping

• When filling the generator with fuel, ensure that there is no air in the piping.
• In case there is air in the piping, remove it by unscrewing the fuel pump until no air bubbles come out from the diesel and then retighten the screws again.

CHECKING & OPERATING THE ENGINE

Check the lube oil level

• Check the lube oil level prior to each starting.
• It is very important to ensure that the oil level is between the upper and lower limit of the oil dipstick.

Engine break-in

• Before operating the generator normally, the engine should be broken-in for a period of 20 hours.
• Avoid over-loading the engine during the break-in period.
• Change the lube oil after the break-in period has passed.

   • If the generator fails to start within 10 seconds, wait 15 seconds before attempting to start the generator again.

Note: If it is difficult to start the engine during winter season, add 2 ml lube oil in the inlet gas passage.
Note: It is very important to retighten the dipstick firmly before starting.

BATTERY

• If the battery is of liquid-added type, the electrolyte levels should be checked on a monthly basis.
• The engine can not be started if the electrolyte level is low. In this case, distilled water should be added.
• If the electrolyte level is too high, the liquid will overflow and corrode the parts nearby.
• During operation, the generator can automatically charge the battery.
• If the generator is used as a stand-by generator, the battery should be charged.

OPERATING THE GENERATOR

Operation of the engine

1. Check the lube oil level. If the level is low, add enough oil so that the level is between the upper and lower limit.
2. Run the engine for three minutes without load to heat it up.

Inspection during operation

1. Check whether there is any abnormal sound coming from the generator or whether the generator is vibrating intensely.
2. Check whether the engine is running properly.
3. Ensure that the color of the exhaust gas is not black or too white.
   • If the generator fails to pass the inspection, the operator should stop the generator immediately and contact the supplier.

ADDING THE LOAD

Adding loads to the AC socket

• When starting the generator, look at the indicator light to check whether there any faults.
• The generator should be run at the rated speed (set the speed handler to the ”RUN” position.)
• When the voltage indication on the control panel reaches ±10% of the rated limit, the load can be added.
• In case the generator does not work properly, remove the loads and find the cause of the problem.
• In case of overloading, reduce the load, then start the generator again in a few minutes.
• If the voltage indication is too high or too low, stop the generator and find the cause of the problem.

Adding loads to the DC socket

• Before charging automatic-type batteries, the wire from the cathode of the battery must be disconnected.
• Connect the charging wire between the battery terminal and the generator anode. Pay attention to the anode and cathode.
• Charge the battery in a well-ventilated area.

Note: Before charging the battery, open the battery cover. If the electrolyte liquid temperature is over 45°C, do not charge the battery.
Note: Do not attempt to start a car with the generator.

MAINTENANCE

Caution: Never perform maintenance procedures while the generator is running. Allow the generator to cool before commencing any maintenance procedures.

Warning: Improper maintenance and/or failure to correct any problems prior to operating the generator can cause a malfunction which could cause death or serious injury.

Note: The mark ”•” indicates that a special spanner must be used.

Change the fuel filter

1. Close the fuel switch.
2. Reveal the fuel filter element by loosening the covers of the oil/water separator. Afterwards, replace the fuel filter.

STORAGE

When the generator has not been operated for more than three months, it should be stored. If the generator has been in storage for 6 months, take the following steps before operating it:

1. Drain off the fuel and lube oil.
2. Remove dust and oil from the outer parts of the generator and from the control panel.
3. Clean the crankcase and gear chamber with diesel and kerosene. Afterwards, drain off the diesel and kerosene.
4. Inject the right amount of rust-proofed oil or lube oil without water (heat the lube oil to about 120°C until no foam exists) into the crankcase. Then, run the engine for 3 minutes to circulate the oil to all the moving parts.
5. Inject rust-proofed oil or lube oil without water into the intake manifold and then run the engine rapidly. Once that is done, close the intake/exhaust valve.
6. Wrap the air filter with water-proof paper and insert water-proof paper into the muffler to prevent dust and moisture from entering.
7. Take out the key.
8. Store the generator in a clean, dry and well-ventilated area free of corrosive materials.
