CHECK GENERATOR SURROUNDINGS WARNING Make sure you review each warning in order to prevent fire hazard.
  • Page 16 WARNING Death, personal injury and/or property damage may occur unless instructions are followed carefully. ■ Use battery of recommended capacity. ■ Turn the starter switch to the “STOP” position when mounting or dismounting battery. When mounting battery, connect the positive (+) cable first and then the negative (-) cable to the battery.
  • Page 17: Operating Procedures

    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". (b) Turn the AC circuit breaker to the position "OFF".
  • Page 18 (e) Pull the starter handle slowly until passing the compression point (resistance will be felt), then return the handle to its original position and pull briskly. ■ If the engine fails to start after several attempts, repeat above procedures with choke lever returned to "OPEN" position.
  • Page 19 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.
  • Page 20 Stop the generator immediately, check the appliance and / or generator for overloading or detect and have repaired as necessary by SUBARU Industrial Power Products dealer or service shop. [ CAUTION ] The duplex 120V receptacle is protected by a GFCI (Ground Fault Circuit Interrupter).
  • Page 21 (d) Check and confirm whether circuit breaker position is “ ON ”. (e) Turn on the switch of the appliance. GFCI RECEPTACLE After starting the engine, check the GFCI for proper functioning by the following test procedure. ■ Push blue TEST button, The red RESET button will pop out exposing the word TRIP.
  • Page 22 FULL POWER SWITCH (Except RGX2900) 1 2 0 V Select the voltage using the FULL 2 4 0 V 1 2 0 V POWER SWITCH in accordance with the electrical appliance. Refer to TABLE 2. [ CAUTION ] Change the FULL POWER SWITCH after turning the AC circuit breaker to “OFF”.
  • Page 23 IDLE CONTROL SWITCH (Except RGX2900) IDLE CONTROL SWITCH automatically reduces engine speed when load is OFF, and automatically increases engine speed to rated r.p.m. when load is ON. IDLE CONTROL SWITCH provides fuel economy and low noise operation at no-load running.
  • Page 24 (2) DC APPLICATION The DC terminal is used only for charging Black 12 volt batteries. It provides up to 12V-8.3A (100W) of maximum power. CONNECTION OF CABLE : ■ Connect positive (red) terminal on generator to positive (+) terminal on battery.
  • Page 25 STOPPING THE GENERATOR (a) Turn off the power switch of the electric equipment and unplug the cord from receptacle of the generator. (b) Turn the AC circuit breaker to the “OFF” position. (c) Allow the engine about 3 minutes to cool down at no-load before stopping.
  • Page 26: Wattage Information

    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.
  • Page 27 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.

    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 Oil drain plug warm.
  • Page 32 HIGH ALTITUDE ENGINE OPERATION ■ 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.
  • Page 33 CHECKING CARBON BRUSH (RGX6500, 7500) If the brush become excessively worn, its contact pressure with the slip ring changes BRUSH HOLDER and causes a roughened surface on the slip ring, resulting in irregular generator performance. Check the brush every 500 hours or if 0.6 to 0.2 in.
  • Page 34: Preparation For Storage

    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.
