(c) If the engine does not start by usual starting procedures, check the oil level.

6.WATTAGE INFORMATION

Some appliances need a "surge" of energy when starting.

This means that the amount of electrical power needed to start the appliance may exceed the amount needed to maintain its use.

Electrical appliances and tools normally come with a label indicating voltage, cycles / Hz, amperage (amps) and electrical power needed to run the appliance or tool.

Check with your nearest dealer or service center with questions regarding power surge of certain appliances or power tools.

Electrical loads such as incandescent lamps and hot plates require the same wattage to start as is needed to maintain use.
■loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during start-up.
■loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
Electrical motors require a large starting current. Power requirements depend on the type of motor and its use. Once enough “surge” is attained to start the motor, the appliance will require only 50% to 30% of the wattage to continue running.
Most electrical tools require 1.2 to 3 times their wattage for running under load during use. For example, a 5,000 watt generator can power a 1800 to 4000 watt electrical tool.
■loads such as submersible pumps and air compressors require a very large force to start. They need 3 to 5 times the normal running wattage in order to start. For example, a 5,000 watt generator would only be able to drive a 1,000 to 1,700 watt pump.

NOTE:

The following wattage chart is general guide only. Refer to your specific appliance for correct wattage.

To determine the total wattage required to run a particular electrical appliance or tool, multiply the voltage figure of the appliance/tool by the amperage (amps) figure of same. The voltage and amperage (amps) information can be found on a name plate which is normally attached to electrical appliances and tools.

Applications	Applicable Wattage(W)

Fluorescent lamp, Electric tool 1200 1500 2100 2750 3300
Mercury lamp 900 1100 1500 2000 2400
Pump, Compressor 550 650 950 1250 1500

VOLTAGE DROP IN ELECTRIC EXTENSION CORDS

When a long electric extension cord is used to connect an appliance or tool to the generator, a certain amount of voltage drop or loss occurs in the extension cord which reduces the effective voltage available for the appliance or tool.

The chart below has been prepared to illustrate the approximate voltage loss when an extension cord of 300 feet (approx. 100 meters) is used to connect an appliance or tool to the generator.

7. SPARK ARRESTER

In a dry or wooded area, it is recommendable to use the product with a spark arrester. Some areas require the use of a spark arrester. Please check your local laws and regulations before operating your product.

The spark arrester must be cleaned regularly to keep it functioning as designed. A clogged spark arrester :

●Prevents the flow of exhaust gas
- Reduces engine output
- Increases fuel consumption
●Makes starting difficult

If the engine has been running, the muffler and the spark arrester will be very hot. Allow the muffler to cool before cleaning the spark arrester.

How to remove the spark arrester

1. Remove the flange bolts from the muffler cover and remove the muffler cover.
2. Remove the special screw from the spark arrester and remove the spark arrester from the muffler.

Clean the spark arrester screen

Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid damaging the screen.

The spark arrester must be free of breaks and holes. Replace the spark arrester if it is damaged.

Install the spark arrester, and muffler protector in the reverse order of disassembly.

8. MAINTENANCE SCHEDULE

MAINTENANCE, REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

*Note: 1. Initial oil change should be performed after first twenty (20) hours of operation.
Thereafter change oil every hundred (100) hours.
Before changing oil, check for a suitable way to dispose of old oil.
Do not pour it down into sewage drains, onto garden soil or into open streams.
Your local zoning or environmental regulations will give you more detailed instructions on proper disposal.
*Note: 2. As to the procedures for these items, please refer to the SERVICE MANUAL or consult your nearest service dealer.

9. "HOW-TO" MAINTENANCE

ENGINE OIL CHANGE

Change engine oil every 100 hours. (For new engine, change oil after 20 hours.)

(a) Drain oil by removing the drain plug and the oil filler cap while the engine is warm.

(b) Reinstall the drain plug and fill the engine with oil until it reaches the upper level on the oil filler cap.

Use fresh and high quality lubricating oil to the specified level as directed on page 6. If contaminated or deteriorated oil is used or the quantity of the engine oil is not sufficient, the engine damage will result and its life will be greatly shortened.

SERVICING THE AIR CLEANER

Maintaining an air cleaner in proper condition is very important.

Dirt induced through improperly installed, improperly serviced or inadequate elements damages and wears out engines. Keep the element always clean.

(a) Remove the bolt of air cleaner cover. (RGX6500, 7500) Remove the air cleaner cover and cleaner element.

(b) Urethane form: Wash urethane form element in kerosene or diesel fuel. Then saturate the element in a mixture of 3 parts kerosene or diesel fuel and 1 part engine oil. Squeeze the element to remove the mixture and install it in the air cleaner.

NOTE :

Instead of washing oil (kerosene), it is possible to wash the urethane foam element in a solution of mild detergent and warm water.

Then rinse the element thoroughly in clean water.

Allow the element to dry thoroughly. Soak the element in clean engine oil and squeeze out excess oil.

RGX2900, 3600 RGX4800 RGX6500, 7500

CLEANING AND ADJUSTING SPARK PLUG

(a) If the plug is contaminated with carbon, remove it using a plug cleaner or wire brush.
(b) Adjust the electrode gap to 0.6 to 0.7 mm (0.024 to 0.028 in.).

Spark plug : BR-6HS (NGK)

CLEANING FUEL STRAINER

Dirt and water in the fuel are removed by the fuel strainer.

(a) Remove the strainer cup and throw away water and dirt.
(b) Clean the screen and strainer cup with gasoline.
(c) Tightly fasten the cup to main body, making sure to avoid fuel leak.

Exploded view diagram of a mechanical device showing internal components (no text or labels)

Please have an authorized SUBARU Industrial Power Products service dealer modify this engine if it is to be run continuously above 5,000 feet (1,500 meters). Failure to do so, may result in poor engine performance, spark plug fouling, hard starting, and increased emissions.
Carburetor modification by an authorized SUBARU Industrial Power Products service dealer will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emission standards throughout its useful life.
An engine converted for high altitudes can not be run at 5,000 feet or lower. In doing so, the engine will overheat and cause serious engine damage. Please have an authorized SUBARU Industrial Power Products service dealer restore high altitude modified engines to the original factory specification before operating below 5,000 feet.

CHECKING CARBON BRUSH (RGX6500, 7500)

If the brush become excessively worn, its contact pressure with the slip ring changes and causes a roughened surface on the slip ring, resulting in irregular generator performance.

Check the brush every 500 hours or if generator performance is irregular.

If the brush is 5 mm long or less, replace it with a new one.

(a) Remove the brush cover.

(b) Disconnect the wire connector and remove the brush.

(c) Carefully note the brush direction and relative position with the slip ring when installing new brush.

10. PREPARATION FOR STORAGE

The following procedures should be followed prior to storage of your generator for periods of 6 months or longer.

Drain fuel from fuel tank carefully by disconnecting the fuel line. Gasoline left in the fuel tank will eventually deteriorate making engine-starting difficult.

Remove the carburetor float chamber and also drain the carburetor.

Change engine oil.

Check for loose bolts and screws, tighten them if necessary.

Clean generator thoroughly with oiled cloth. Spray with preservative if available. NEVER USE WATER TO CLEAN GENERATOR!

Pull starter handle until resistance is felt, leaving handle in that position.

Store generator in a well ventilated, low humidity area.

11. TROUBLESHOOTING

When generator engine fails to start after several attempts, or if no electricity is available at the output socket, check the following chart. If your generator still fails to start or generate electricity, contact your nearest SUBARU Industrial Power Products dealer or service shop for further information or corrective procedures.

When Engine Fails to Start:

Check if choke lever is in its proper position.		Set the choke lever to “CLOSE” position.
Check if fuel valve is open. If closed, open f
Check fuel level.		If empty, refill fuel tank making sure not to overfill.
Check if engine switch is in OFF. Turn engine switch to ON.
Check to make sure generator is not connected to an appliance.		If connected, turn off the power switch on the connected appliance and unplug.
Check spark plug for loose spark plug cap.		If loose, push spark plug cap back into place.
Check spark plug for contamination. Remove spark plug		and clean electrode.

When No Electricity Is Generated at Receptacle:

Check to make sure AC circuit breaker is in the “ON” position.		After making sure that the total wattage of the electrical appliance is within permissible limits and there are no defects in the appliance, turn the AC circuit breaker to the “ON” position. If protectors continue to actuate, consult your nearest servicing dealer.
Check AC receptacle and DC terminals for loose connection.		Secure connection if necessary.
Check to see if engine starting was attempted with appliances already connected to generator.		Turn off switch on the appliance, and disconnect cable from receptacle. Reconnect after generator has been started properly.
Low power. Carbon brushes are excessively worn
