RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ1 1. SAFETY PRECAUTIONS Please make sure you review each precaution carefully. ENGLISH WARNING Do not operate the generator near gasoline or gaseous fuel because of the potential danger of explosion or fire. Do not fill the fuel tank with fuel while the engine is running. Do not smoke or use open flame near the fuel tank. Be careful not to spill fuel during refueling. If fuel is spilt, wipe it off and let dry before starting the engine.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ2 WARNING Do not operate in rain, in wet or damp conditions, or with wet hands. The operator may suffer severe electric shock if the generator is wet due to rain or snow. WARNING If wet, wipe and dry it well before starting. Do not pour water directly over the generator, nor wash it with water. WARNING Be extremely careful that all necessary electrical grounding procedures are followed during each and every use. Failure to do so can be fatal.

PRE-OPERATION CHECKS Before checking or refilling oil, be sure generator is located on stable and level surface with engine stopped. ■ ■ ■ Remove oil filler cap and check the engine oil level. If oil level is below the lower level line, refill with suitable oil (see table) to upper level line. Do not screw in the oil filler cap when checking oil level. ENGLISH CHECK ENGINE OIL Oil filler cap (Oil gauge) Upper level Lower level Change oil if contaminated.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ8 CHECK ENGINE FUEL. WARNING Do not refuel while smoking or near open flame or other such potential fire hazards. Otherwise fire accident may occur. ■ ■ ■ Check fuel level at fuel level gauge. If fuel level is low, refill with unleaded automotive gasoline. LEVEL Be sure to use the fuel filter screen on the fuel filter neck. Fuel tank cap Fuel Amount up to "LEVEL" position Fuel filter screen 12.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ9 CHECKING COMPONENT PARTS ENGLISH Check following items before starting engine: ■ Fuel leakage from fuel hose, etc. ■ Bolts and nuts for looseness. ■ Components for damage or breakage. ■ Generator not resting on or against any adjacent wiring. CHECK GENERATOR SURROUNDINGS WARNING Make sure you review each warning in order to prevent fire hazard. ■ Keep area clear of in flammables or other hazardous materials.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ10 5. OPERATING PROCEDURES STARTING THE GENERATOR ［CAUTION］ Check the oil level before each operations as outlined by the article "CHECK ENGINE OIL" (a) Turn the Engine switch to the position "ON". ON OFF (b) Turn the AC circuit breaker to the position "OFF". ON OFF OFF (c) Open the fuel cock. CLOSE CLOSE OPEN (d) Set choke lever to close if the engine is cold.
(e) Pull the starter handle slowly until resistance is felt. This is the "compression" point. Return the handle to its original position and then pull swiftly. ■ ■ ■ y dl pi a ll r Pu If the engine fails to start after several attempts, repeat above procedures with choke lever returned to "OPEN" position. Do not fully pull out the rope. After starting, allow the starter handle to return to its original position while still holding the handle.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ12 USING ELECTRIC POWER WARNING Make sure that the appliance is switched OFF before connecting it to the generator. ■ Do not move the generator while it is running. ■ Be sure to ground the generator if the connected appliance is grounded. Failure to ground unit may lead to electrical shock. ■ (1) AC APPLICATION A Single voltage type (a) Check the voltmeter for proper voltage. ■ This generator is thoroughly tested and adjusted in the factory.
Up to total 15 ampere from two receptacles Up to 30 amperes Up to 15 amperes Up to 16 amperes TABLE 1 WARNING ■ ■ To take power out from the TWIST LOCK RECEPTACLE, insert the plug into the receptacle, and turn it clockwise to the lock position. TWIST Be sure to ground the generator if the connected electrical device Is grounded. NOTE : When the AC circuit breaker turns off during operation, the generator is over loaded or the appliance is defective.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ14 B Dual voltage type (RGX4800) FULL POWER SWITCH (a) Select the voltage using the FULL POWER SWITCH in accordance with the electrical appliance. Refer to TABLE 2. 120V 120V 240V ［CAUTION］ Change the FULL POWER SWITCH after turning the AC circuit breaker to "OFF". (b) Operate in the same way as step (a) through step (d) of single voltage type. NOTE : Voltmeter always indicates the lower voltage whichever the FULL POWER SWITCH is set.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ15 The DC terminal is used only for charging 12 volt batteries. It provides up to 12V-8.3A (100W) of maximum power. Red Black - CONNECTION OF CABLE : ■ ■ ■ ENGLISH (2) DC APPLICATION + Connect positive (red) terminal on generator to positive (+) terminal on battery. Connect negative (black) terminal on generator to negative (-) terminal on battery. Both AC and DC output can be used at the same time if the total output is within rated output of the generator.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ16 ON STOPPING THE GENERATOR (a) Turn off the power switch of the electric equipment and unplug the cord from receptacle of the generator. OFF (b) Turn the AC circuit breaker to the "OFF" position. OFF ON (c) Allow the engine about 3 minutes to cool down at no-load before stopping. (d) Turn the Engine switch counterclockwise to the position "OFF". OFF ( e) Close the fuel cock.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ17 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.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ18 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.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ19 7. MAINTENANCE SCHEDULE DAILY ■ ■ EVERY 50 HOURS ■ EVERY 100 HOURS EVERY 200 HOURS EVERY 500 HOURS EVERY 1,000 HOURS (24 MONTHS) ■ Check oil level. Check all components according to "PREOPERATION CHECKS." Wash cleaner element. -more often if used in dirty or dusty environments. Check spark plug, clean if necessary.

(a) Remove the strainer cup and throw away water and dirt. (b) Clean the screen and strainer cup with gasoline.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ22 9. 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 enginestarting difficult. Drain screw Remove the carburetor float chamber and also drain the carburetor. ■ ■ ■ ■ Change engine oil.
RGX48000(GEN)_GU2122 05.7.14 1:21 PM ページ23 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 Robin 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" Check if fuel cock is open.
