® PORTABLE GASOLINE GENERATORS GENERAL INFORMATION Reddy portable generators are rugged and compact. These models provide dependable, trouble-free service. The alternators are brushless with revolving fields. Honda gasoline engines provide long life under heavy use. Honda engines have overhead valves (OHV). This provides high performance with lower fuel consumption. These engines are governed to maintain engine speed of 3600 RPM under load. 3600 RPM engine speed provides 120/240V, 60 Hz power.

® PORTABLE GASOLINE GENERATORS FULL POWER SELECTOR SWITCH GENERATOR FEATURES OIL ALERT SYSTEM The oil alert system protects the engine from low oil damage. This system automatically shuts down the engine and prevents engine restarting if the oil level falls too low. Note: When this happens, the engine switch remains in the ON position. The oil alert system is wired into the ON/OFF Switch. If this system shuts down the engine, the engine will not start until you add oil.
OWNER’S MANUAL RECEPTACLE CIRCUIT BREAKER GENERATOR FEATURES Continued 2. If the GFCI receptacle tests okay, restore power by pushing the RESET button back in. The test lamp should work at this time. IMPORTANT: You must press the RESET button firmly and fully. It should lock into place. If the GFCI does not lock into place, do not use receptacle. Contact a qualified electrician for repairs. RE The circuit breakers protect the receptacles and alternator. Overloading generator will trip circuit breaker.
® PORTABLE GASOLINE GENERATORS HANDLES AND TOP COVER (Model RGH11000AIE) Follow the steps below to attach the handles and top cover to Model RGH11000AIE: 1. Remove the two bolts, lock nuts, and washers holding side panels to control panel end of roll cage.

® PORTABLE GASOLINE GENERATORS STANDBY INSTALLATION TO HOME OR BUILDING 1. WARNING: Have standby installation performed by a skilled, licensed electrician. Do not let anyone else wire into a utility circuit. Personal injury, equipment damage, or damage to home could occur. 2. IMPORTANT: This generator will not power your entire home. Most home utility electric service is more than 60 amps. This will exceed generator output. Only power needed items during a power outage.
OWNER’S MANUAL OPERATION Model RGH11000AIE also has a 120/240V, 50-amp receptacle (see Figure 17). POWER CORD AND PLUG REQUIREMENTS GENERAL INFORMATION Models RGH3000 and RGH3000PR have only the 120V, 15-amp GFCI duplex receptacle. 120V, 30-amp twist-lock receptacle • NEMA L5-30P plug • Three-wire, 30-amp cord This generator is not large enough to power your entire home. Do not connect generator to any existing electrical circuits. Plug items directly into generator receptacles.
® PORTABLE GASOLINE GENERATORS OPERATION 4. Continued PRESTART Operate generator on a firm, dry, and clean surface. The surface must be level. Protect generator from heavy dust, sand, dirt, rain, or snow. Do not locate generator near standing water and snow. Make sure area is well vented. WARNING: Only responsible adults should use generator. Never let anyone operate generator without proper instructions.
OWNER’S MANUAL OPERATION Continued HONDA 6. ON OFF Engine Switch START Note: The 250 Volt/50 Amp receptacle is not connected through the Auto-Idle circuit. The Auto-Idle switch must be turned off to get full power out of this receptacle (see Figure 26). The Auto-Idle system should be turned OFF when generator is shut down.
® PORTABLE GASOLINE GENERATORS Fuel Valve Lever (Off Position) OPERATION STOPPING ENGINE Continued HIGH ALTITUDE OPERATION IMPORTANT: The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle. This generator will not perform well at high altitudes without proper adjustment. See engine owner’s manual for details. Follow the steps below to stop engine. 1. Remove all electrical loads from generator (see Disconnecting Electrical Loads).
OWNER’S MANUAL MAINTENANCE AND REPAIRS WARNING: Only a qualified electrical service person should service and repair the alternator on this generator. Use only factory approved replacement parts. CAUTION: The engine speed is preset. The throttle is locked in preset position. Do not adjust throttle. Preset position lets engine run at 3600 RPM under load. The engine must maintain 3600 RPM for generator to create correct voltage. Running engine at lower speeds will damage generator and powered items.
