Anleitung Zusammenfassung
Battery voltage is delivered to that circuit board via a 15-amp fuse. These overcurrent protection devices will open if the circuit is overloaded. If a circuit breaker opens or a fuse element melts, find the cause of the overload before resetting the circuit breaker or replacing the fuse. 4.8 DC FUSE The generator panel’s 15-amp AGC fuse (Figure 4.4) protects the DC control circuit against overload. The fuse is wired in series with the battery output lead to the panel. If the fuse element has melted open, cranking or starting the engine cannot occur. Replace the fuse using only an identical 15-amp AGC replacement. Figure 4.4 – Location of 15-amp Fuse 15 4.9 ENGINE COOLANT Check the coolant level in the coolant recovery bottle. • Add the recommended coolant mixture as necessary, see Section 1.10. • Periodically remove the radiator pressure cap to make sure the coolant recovery system is functioning properly. Coolant should be at the bottom of the radiator filler neck. If the coolant level is low, inspect the gasket in the radiator pressure cap. Replace the cap, if necessary. To have the pressure cap tested, contact a Generac/Guardian Authorized Dealer. Inspect the cooling system and coolant recovery system for leaks. 4.10 MISCELLANEOUS MAINTENANCE • 4.10.1 CLEANING THE GENERATOR Keep the generator as clean and as dry as possible. Dirt and moisture that accumulate on internal generator windings have an adverse effect on insulation resistance. Periodically, clean the generator’s exterior surfaces. A soft brush may be used to loosen caked on dirt. Use a vacuum system or dry, low pressure air to remove any accumulations of dirt. The generator is housed inside an all-weather enclosure; clean the enclosure with a soft, damp cloth or sponge and water. Once each year, have the generator cleaned and inspected by a Generac/Guardian Authorized Dealer. Service technicians will use dry, low pressure air to clean internal windings. Parts inside the control console should be cleaned and inspected at this time as well. Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying. • 4.10.2 RODENT PROTECTION The intrusion of rodents into the generator set can cause a wide range of problems, from failure of the unit to start, to personal injury and, in extreme circumstances, short circuit or fire. Although the unit was designed to limit this problem, further precautions can be taken by the owner to help minimize both the chance of rodent entry and the extent of any damage. The following inspection should be performed. 1. The base frame of the unit contains an optional fuel inlet location and four lifting holes that are capped at the factory. These caps are sometimes removed for transportation during installation but always should be replaced afterwards. Check that they are secured in place. The same applies for any access ports in the roof of the enclosure. If any of these caps are missing, contact a Generac/Guardian Authorized Dealer. 2. Inside the generator set, the chance of rodent entry into the control panel is greatly reduced by the inclusion of adjustable wire connectors. Check that the wire connector screws are tight, closing off any gap between the access holes and the wires.

Start the engine and let it warm up. 2. Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down. 3. Once the unit has shut down, it will signal a fault on the control panel. 4. Set the AUTO/OFF/MANUAL switch to OFF and turn off the UTILITY power to the transfer switch. 5. While the engine is still warm from running, drain the oil completely. Refill the crankcase with SAE 15W-40 oil having API Service Class SG, SH or SJ. 6. Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase. 7. Remove the spark plug(s) and spray fogging agent into the spark plug(s) threaded openings. Reinstall and tighten the spark plug(s). 8. Remove the battery and store it in a cool, dry room on a wooden board. Never store the battery on any concrete or earthen floor. 9. Clean and wipe the entire generator. • 4.11.2 RETURN TO SERVICE To return the unit to service after storage, proceed as follows: 1. Verify that UTILITY power is turned off to the transfer switch and that the AUTO/OFF/MANUAL switch is set to OFF. 2. Check the tag on the engine for oil viscosity and classification. Verify that the correct recommended oil is used in engine, see Section 4.2.1. If necessary, drain and refill with the proper oil. 3. Check the battery. Fill all cells to the proper level with distilled water. DO NOT USE TAP WATER I...
