Maintenance Preventive Maintenance Dirt or debris can cause improper operation and equipment damage. Clean generator daily or before each use. Keep area around and behind muffler free from combustible debris. Inspect all cooling air openings on generator. WARNING Do not insert any object through the air cooling slots. Generator can start at any time and could result in death, serious injury and unit damage. • Use a damp cloth to wipe exterior surfaces clean. • Use a soft bristle brush to loosen caked on dirt, oil, etc. • Use a vacuum to pick up loose dirt and debris. • Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed. NOTICE: DO NOT use a garden hose to clean generator. Water can enter engine fuel system and cause problems. If water enters generator through cooling air slots, some water will be retained in voids and crevices of rotor and stator winding insulation. Water and dirt buildup on generator internal windings will decrease insulation resistance of windings. Engine Maintenance WARNING Accidental start-up. Disconnect spark plug wires when working on unit. Fail- ure to do so could result in death or serious injury. Inspect engine oil level prior to each use, or every 8 hours of operation. 1. Place generator on a level surface. 2. Clean area around oil fill. 3. Remove oil fill cap and wipe dipstick clean. 000115 4. Screw dipstick into filler neck. Verify oil level is within safe operating range as shown. Engine Oil Recommendations All oil should meet minimum American Petroleum Institute (API) Service Class SJ, SL or better. Use no special additives. Select the oil's viscosity grade according to the expected operating temperature (also see chart). • Above 40° F, use SAE 30 • Below 40° F and down to 10° F, use 10W-30 • All temperatures, use synthetic 5W-30 Use petroleum based oil for engine break-in before using synthetic oil. 10W-30 SAE 30 Synthetic 5W-30 000399 CAUTION Any attempt to crank or start the engine before adding the recom- mended type and quantity of engine oil can result in engine damage. 000116 5. Add recommended engine oil as necessary. 6. Replace oil fill cap and hand-tighten. NOTICE: oil fill point. Some units have more than one oil fill location. It is only necessary to use one Change Engine Oil WARNING Accidental start-up. Disconnect spark plug wires when working on unit. Fail- ure to do so could result in death or serious injury. When using generator under extreme, dirty, dusty conditions, or in extremely hot weather, change oil more frequently. NOTICE: Don't pollute. Conserve resources. Return used oil to collection centers. Change oil while engine is still warm from running, as follows: 1. Place generator on a level surface. 2. Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug. 3. Clean area around oil fill, and oil drain plug. 4. Remove oil fill cap. 5. Remove oil drain plug and drain oil completely into a suit- able container. 6. Install oil drain plug and tighten securely. 14 Owner's Manual for Portable Generator
