AE00091

CONNECTION

w Before the generator can be connected to a build- ings electrical system, a licensed electrician must install an isolation (transfer) switch in the build- ings main fuse box. The switch is the connection point for generator power and allows selection of generator or main line power to the building. This will prevent the generator from charging the main power line (backfeeding) when the main power supply has failed or has been turned off for line repair. Backfeeding can electrocute or injure line maintenance personnel. Also, generator and build- ing electrical system damage can occur when nor- mal operating power returns if unit is used without an isolation switch.

AE00086

EXTENSION CORD NOTES 9 When using an extension cord, its total length

should not exceed 60 meters for cross section of 1.5 mm square and 100 meters for cross section of 2.5 mm square.

9 This extension cord should be protected by a tough flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

Overload indicator light The overload indicator light 1 comes on when an overload of a connected electrical device is detected, the inverter control unit overheats, or the AC output voltage rises. The electronic breaker will then activate, stopping power generation in order to protect the gen- erator and any connected electric devices. The AC pilot light (green) will go off and the overload indicator light (red) will stay on, but the engine will not stop run- ning.

When the overload indicator light comes on and power generation stops, proceed as follows: 1. Turn off any connected electric devices and stop

the engine. 2. Reduce the total wattage of connected electric

devices within the application range. 3. Check for blockages in the cooling air inlet and

around the control unit. If any blockages are found, remove.

4. After checking, restart the engine.

NOTE: 9 The generator AC output automatically resets

when the engine is stopped and then restarted. 9 The overload indicator light may come on for a

few seconds at first when using electric devices that require a large starting current, such as a compressor or a submergible pump. However, this is not a malfunction.

STORAGE Long term storage of your machine will require some preventive procedures to guard against deterioration.

AE00621

ENGINE 1. Remove the spark plug, pour about one table-

spoon of SAE 10W30 or 20W40 motor oil into the spark plug hole and reinstall the spark plug. Recoil start the engine by turning over several times (with ignition off) to coat the cylinder walls with oil.

2. Pull the recoil starter until you feel compression. Then stop pulling. (This prevents the cylinder and valves from rusting).

3. Clean exterior of the generator and apply a rust inhibitor.

4. Store the generator in a dry, well-ventilated place, with the cover placed over it.

5. The generator must remain in a vertical position when stored, carried or operated.

AE01095

DRAIN THE FUEL 1. Remove the fuel tank cap. Drain the fuel from the

fuel tank into an approved gasoline container using a commercially available hand siphon. Then, install the fuel tank cap.

w 9 Fuel is highly flammable and poisonous.

Check SAFETY INFORMATION (See page 4) carefully.

9 Wipe up any spilled fuel immediately.

2. Remove the cover 1. Drain fuel from the carburetor by loosening the drain screw 2 on the carburetor float chamber.

3. Turn the fuel cock knob to OFF. Start the engine and leave it run until it stops. This will burn any remaining fuel in the carburetor.
