Resumen del manual
3. Check the spark plug gap using a feeler gauge. Adjust the gap to 0.045 inch (1.1 mm) by carefully bending the ground electrode (Figure 4.4). Figure 4.4 – Setting the Spark Plug Gap 4.5 BATTERY MAINTENANCE The battery should be inspected per the “Service Schedule,” Section 4.12, Page 19. The following procedure should be followed for inspection: 1. Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary. 2. Check the battery fluid level of unsealed batteries and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN BATTERIES. 3. Have the state of charge and condition checked. This should be done with an automotive-type battery hydrometer or load test. Standby generators installed with automatic transfer switches will crank and start automatically when normal (utility) source voltage is removed or is below an acceptable preset level. To prevent such automatic start-up and possible injury to personnel, do not connect battery cables until the normal source voltage at the transfer switch is correct and the system is ready to be placed into operation. Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery. Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If fluid is spilled, flush the affected area immediately with clear water. Do not dispose of the battery in a fire. The battery is capable of exploding. Do not open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and eyes. The battery represents a risk of high short circuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles. Battery replacement Generac uses a Group 27F vented type battery that has 600 CCA @ 0. F. Generac’s part number is 058665. Note: The BCI number should be located directly on the battery. ! ! ! DANGER Air Cleaner Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator Section 4 — Maintenance Guardian Liquid-cooled 40 kW Generator 4.6 COOLING SYSTEM Air intake and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow. Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down. The exhaust system of this product gets extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system. 4.7 OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL SYSTEM Engine cranking, start-up and running are controlled by a solid-state engine controller circuit board. 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, you should 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 on Page 7. • 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 remov...
