GA-6RZ2— GENERAL INFORMATION WARNING: Before connecting this generator to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch. Serious injury or death may result without this transfer switch. GA-6RZ2 FAMILIARIZATION Generator The Multiquip Model GA-6RZ2 generator has been designed as a portable lightweight power source for 60 Hz (singlephase) vibrators, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.
GA-6RZ2 — CONTROLS AND INDICATORS Figure 1. Controls and Indicators PAGE 10 — GA-6RZ2 A.C. GENERATOR — PARTS & OPERATION MANUAL — REV.
GA-6RZ2— INSTALLATION Outdoor Installation Indoor Installation Install the generator in a location where it will not be exposed to rain or sunshine. Make sure that the generator is on secure level ground so that it cannot slide or shift around. Also install the generator in a manner so that the exhaust will not be discharged in the direction of nearby homes. Exhaust gases from gasoline engines are extremely poisonous.
GA-6RZ2— PRE-SETUP General Inspection Prior to Operation Circuit Breaker This generator has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have occurred in transit. To protect the generator from an overload, a 2-pole 21 amp circuit breaker is provided on the control box. Make sure to switch this circuit breaker to the "OFF" position prior to starting the engine.
GA-6RZ2— PRE-SETUP Lubrication Oil Fuel Fill the engine crankcase with lubricating oil through the filler hole, but do not overfill. Make sure the generator is level. With the dipstick inserted all the way, but without being screw into the filler hole, verify that the oil level is maintained between the two notches on the dipstick. Close the fuel cock before filling the tank. Fill the fuel tank with clean and fresh unleaded gasoline. Do not fill the tank beyond capacity.
GA-6RZ2— INSTRUMENTATION CAUTION : Start Switch When using a combination of dual receptacles, total load should not exceed the rated capacity of the generating. Power Outlets The generator has the following 120/240 volt 60 Hz (singlephase) receptacles. z Single Phase One Duplex NEMA (GFCI) 5-20R (120V, 20 Amp) One Twist Lock NEMA L5-30R (120V, 30 Amp) One Twist Lock NEMA L6-20R (240V, 20 Amp) Push this switch to start the engine (electric start only).
GA-6RZ2— LOAD APPLICATION Single Phase Load CAUTION: Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generator for operating the equipment. Motors and motor-driven equipment draw much greater current for starting than during operation. Generally, the wattage listed on the nameplate of the equipment is its rated output.
GA-6RZ2— OPERATING INSTRUCTIONS Before Starting 1. Be sure to disconnect the electrical load and switch the main circuit breaker to the “OFF” position prior to starting the engine. 2. Never start the engine with the main circuit breaker “ON”. 3. Check the lubricating oil level prior to starting the engine. Make sure the generator is level. The oil level must be maintained between two notches on the dipstick. 4. When there is not enough lubricating oil, fill the crankcase with high grade motor oil.
GA-6RZ2— MAINTENANCE General Inspection Service Daily At least daily or prior to each use, the generating set should be cleaned and inspected for deficiencies. Check for loose, missing or damaged nuts, bolts or other fasteners. Also check for fuel or oil leaks. If engine is operating in very dusty and dry grass conditions. A clogged air cleaner will result in high fuel consumption, loss of power and excessive carbon buildup in the combustion chamber.
GA-6RZ2— PREPARATION FOR LONG -TERM STORAGE Generator Storage For storage of the generating set for over 30 days, the following is required: z Drain the fuel tank completely. z Run the engine until the gasoline in the carburetor is completely consumed. z Completely drain the oil from the crankcase and refill with fresh oil. z Remove the spark plug, pour 2 or 3 cc of SAE 30 oil into the cylinder and crank slowly to distribute the oil.
