Anleitung Zusammenfassung
DANGER . Do not attempt to adjust the governor. Only qualified service facilities should adjust the governor. Excessively high operating speeds are dangerous and increase the risk of personal injury. Low speeds impose a heavy load on the engine when adequate engine power is not available and may shorten engine life. Correct rated frequency and voltage are supplied only at the proper governed speed. Some connected electrical load devices may be damaged by incorrect frequency and/or voltage. Only qualified service technicians should adjust the governed speed. .. .. • • • .. .. .. .. • • .. Standby Generator Sets Maintenance 10-2 Maint011 Rev. D 06/07 CHANGING ENGINE OIL Refer to maintenance performed by service facilities for engine oil and filter change frequencies. Drain the oil while the engine is still warm from running. This means warm up the engine, shut it down and drain immediately as follows: 1. Remove OIL DRAIN HOSE from its retaining clip. 2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container. 3. When all oil has drained, install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip. 4. Turn OIL FILTER (Figure 10.2) counterclockwise and remove. Properly dispose of old filter. Figure 10.2 – Oil Filter OIL FILTER OIL DIPSTICK 5. Apply light coating of new engine oil to seal of new oil filter.-Install FILTER and tighten by hand only. DO NOT OVER TIGHTEN. 6. Remove OIL FILL CAP. Add recommended oil (see SPECIFICATIONS). DO NOT FILL ABOVE THE DIPSTICK “FULL” MARK. Crankcase oil capacity is 4.0 U.S. quarts (3.8 liters). . After refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIPSTICK “ADD” MARK. 7. Start engine and check for oil leaks. CHANGING THE ENGINE AIR CLEANER To replace the engine air cleaner, simply remove the air cleaner cover and replace the air filter making sure it is positioned properly before reattaching the cover (Figure 10.3). See the “Service Schedule,” for air cleaner maintenance. .. .. Figure 10.3 – Engine Air Cleaner Air Cleaner (Doors Removed for Clarity) SPARK PLUGS Reset the spark plug gap or replace the spark plugs as necessary (Figure 10.4). 1. Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plugs to clean. 2. Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule” section for recommended inspection. 3. Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.76 mm (0.030 inch) by carefully bending the ground electrode (Figure 10.4). Figure 10.4 – Setting the Spark Plug Gap COOLANT CHANGE Every year, have a service facility drain, flush and refill the cooling system. See “Specifications” for cooling system recommendations. .. ..

D 06/07 SET PLUG GAP AT 0.76 mm (0.030 inch) Standby Generator Sets Maintenance Standby Generator Sets Maintenance MISCELLANEOUS MAINTENANCE • CLEANING THE GENERATOR Keep the generator as clean and as dry as possible. Dirt and moisture that accumulates on internal generator windings have an adverse effect on insulation resistance. Periodically clean generator 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 Service Dealer. That dealer 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. • BATTERY All lead-acid storage batteries discharge when not in use. Refer to specific instructions and warnings that accompany the battery. If such information is not available, observe the following precautions when handling a battery: • DO NOT use jumper cables and a booster battery to crank or start the generator engine. • DO NOT recharge a weak battery while it is installed in the generator. Remove battery from generator and recharge in a well-ventilated area, away from fuel vapors, sparks, heat or flames. • Battery electrolyte fluid is an extremely caustic sulfuric solution that can cause severe burns. DO NOT permit fluid to contact eyes, skin, clothing, painted surfaces, wiring insulation, etc. If any battery fluid is spilled, flush the affected area with clear water immediately. • Always wear safety glasses, rubber apron and gloves when handling a battery. • Batteries give off explosive hydrogen gas while charging. The gas can form an explosive ...
