Remove cover and set aside. n Loosen the screw in the center of the air filter cover. Remove the cover and set aside. n Remove the air filter. n Wash the air filter with warm, soapy water. Rinse and squeeze to dry. n Reinstall the air filter. NOTE: Make sure the filter is seated properly inside the generator. Installing the filter incorrectly will allow dirt to enter the engine, causing rapid engine wear. n Reinstall the air filter cover. Tighten screw to secure. n Reinstall the engine cover. Tighten screws to secure. CHANGING ENGINE LUBRICANT See Figure 13. For best performance, engine lubricant should be changed after every 100 hours or 6 months of operation. n Loosen the knob at the side of the engine cover. Remove cover and set aside. n Loosen the two screws and remove the oil drain cover. n Remove the oil fill cap/dipstick. n Tilt the generator to the side and allow lubricant to drain from the oil fill hole into an approved container. NOTE: Drain the lubricant while the engine is still warm but not hot. Warm lubricant will drain quickly and more completely. WARNING: Do not change engine lubricant while it is hot. Accidental contact with hot engine lubricant could result in serious burns. n Return the generator to an upright position and refill with lubricant following the instructions in the Checking/ Adding Lubricant section previously in this manual. For amount of lubricant needed to refill, see Product Specifications earlier in this manual or the accompanying engine manual, if applicable. n Replace and secure the oil cap/dipstick. n Reinstall the oil drain cover and tighten the screws.  Reinstall the engine cover. NOTE: Used lubricant should be disposed of at an a­ pproved disposal site. See your local retailer for more information. SPARK PLUG REPLACEMENT See Figure 14. The spark plug must be properly gapped and free of deposits in order to ensure proper engine operation. To check: n Remove the engine cover. n Remove the spark plug cap. n Clean any dirt from around base of spark plug. n Remove spark plug using spark plug wrench. n Inspect spark plug for damage, and clean with a wire brush before reinstalling. If insulator is cracked or chipped, spark plug should be replaced. For replacement spark plug, see Product Specifications earlier in this manual or the accompanying engine manual, if applicable. n Measure plug gap. The correct gap is 0.024−0.028 in. (0.60-0.70 mm). To widen gap, if necessary, carefully bend the ground (top) electrode. To lessen gap, gently tap ground electrode on a hard surface. n Seat spark plug in position; thread in by hand to prevent cross-threading. n Tighten with wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression. NOTE: An improperly tightened spark plug will become very hot and could damage the engine. NOTICE: Be careful not to cross-thread the spark plug. Cross-­ threading will seriously damage the product. n Reinstall the spark plug cap. n Reinstall the engine cover. Tighten screws to secure. CLEANING THE EXHAUST PORT AND MUFFLER Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas-powered products, you may need to remove these deposits to restore performance. We highly recommend that only qualified service technicians perform this service. SPARK ARRESTOR See Figure 15. NOTICE: This product is equipped with a spark arrestor that has been evaluated by the USDA Forest Service; however, product users must comply with Federal, State, and local fire prevention regulations. Check with appropriate authorities. Contact customer service or a qualified service center to purchase a replacement spark arrestor. 19 - English
