OPERATION BEFORE STARTING THE INVERTER BEFORE STARTING THE INVERTER, REVIEW SAFETY SECTION STARTING ON PAGE 4. Location Selection – Before starting the inverter, avoid exhaust and location hazards by verifying: • You have selected a location to operate the inverter that is outdoors and well ventilated. • You have selected a location with a level and solid surface on which to place the inverter.
OPERATION 1-2019 NOTICE Even with a carburetor modification, engine horsepower will decrease about 3.5% for each 300 meter (1,000 foot) increase in altitude. The effect of altitude on horsepower will be greater if no carburetor modification is made. A decrease in engine horsepower will decrease the power output of the inverter. Contact our service team to order altitude kits. POWER CORD Using Extension Cords Cummins Inc. assumes no responsibility for the content within this table.
OPERATION 1-2019 TRANSPORTING THE INVERTER POWER OUTPUT AND DEMAND The inverter should be stopped and the fuel control switch should be turned to the OFF position before transporting the inverter. Keep the unit level during transport to minimize the possibility of fuel leakage or, if possible, drain out the fuel prior to transport. 120-Volt AC devices have two different electric power demands that must be taken into consideration, namely the running power and the starting/peak power.
OPERATION 1-2019 INITIAL OIL FILL BEFORE ADDING ENGINE OIL, REVIEW SAFETY SECTION STARTING ON PAGE 4. ADDING/CHECKING ENGINE FLUIDS AND FUEL BEFORE ADDING/CHECKING ENGINE FLUIDS AND FUEL, REVIEW SAFETY SECTION STARTING ON PAGE 4. NOTICE DANGER Engine oil must be added when the inverter is on a flat, level surface, or an inaccurate reading may result. Do not overfill. If the engine is overfilled with oil, it can cause serious engine damage.
OPERATION ADDING GASOLINE TO THE FUEL TANK 1-2019 STARTING THE INVERTER WARNING Never refuel the inverter while the engine is running. Always turn the engine off and allow the inverter to cool before refueling. CAUTION Avoid prolonged skin contact with gasoline. Avoid prolonged breathing of gasoline vapors.
OPERATION 1-2019 ELECTRIC START MANUAL START 1. Make sure nothing is plugged into any of the outlets. 1. Make sure nothing is plugged into any of the outlets. Be sure to check oil levels before starting. If it is the first time starting make sure to add oil (see Initial Oil Fill on page 13). 2. Make sure battery is connected (see Hooking Up the Battery on page 7). 3. Make sure the circuit breakers are properly set (see Figure 6). Be sure to check oil levels before starting.
MAINTENANCE 1-2019 HOW TO MANUALLY SET THE CHOKE If the battery is dead or disconnected and you need to manual start, you may need to set the choke by hand for proper operation. 4. Follow the directions for manual starting on page 15. 5. Once the inverter starts the power from the machine will automatically open the choke. If the machine does not move the choke then push the choke manually to the open position below: 1. Remove the engine maintenance panel (see Figure 13 on page 20) 2.
OPERATION 1-2019 STOPPING THE INVERTER Normal Operation During normal operation, use the following steps to stop your inverter: 1. Remove any connected loads from the control panel receptacles. 2. Allow the inverter to run at “no load” to reduce and stabilize engine and alternator temperatures. 3.
MAINTENANCE 1-2019 BEFORE PERFORMING MAINTENANCE ON THE INVERTER, REVIEW THE SAFETY SECTION STARTING ON PAGE 4, AS WELL AS THE FOLLOWING SAFETY MESSAGES. WARNING CAUTION Avoid accidentally starting the inverter during maintenance by removing the spark plug boot from the spark plug. For electric start inverters, also disconnect the battery cables from the battery (disconnect the black negative (-) cable first) and place the cables away from the battery posts to avoid arcing.
MAINTENANCE 1-2019 ENGINE OIL MAINTENANCE Engine Oil Specification 1. Only use the engine oil specified in Figure 14. 2. Only use 4-stroke/cycle engine oil. NEVER USE 2-STROKE/CYCLE OIL. Synthetic oil is an acceptable substitute for conventional oil. Figure 14: Recommended Oil CHECKING ENGINE OIL NOTICE Always maintain proper engine oil level. Failure to maintain proper engine oil level could result in severe damage to the engine and/or shorten the life of the engine.
MAINTENANCE AIR FILTER MAINTENANCE WARNING Never use gasoline or other flammable solvents to clean the air filter. Use only household detergent soap to clean the air filter. Cleaning the Air Filter The air filter must be cleaned after every 50 hours of use or 3 months (frequency should be increased if inverter is operated in a dusty environment). 1. Turn off the inverter and let it cool for several minutes if running. 2. Remove the Engine Service Panel to gain access to the air filter (see Figure 13).
MAINTENANCE 1-2019 DRAINING THE FLOAT BOWL 1. Remove the Engine Service Panel to access the carburetor (see Figure 13 on page 19). 2. Locate the clear plastic hose from the float that is extending towards the bottom of the inverter, pull those hose outside the body and place a suitable container under it to catch the drained fuel (see Figure 16).
MAINTENANCE 1-2019 Spark Plug Maintenance - Continued from page 20 7. Place a clean rag over the opening created by the removal of the spark plug to make sure no dirt can get into the combustion chamber. 8. Inspect the spark plug for: SPARK PLUG GAP • Cracked or chipped insulator • Excessive wear • Spark plug gap of 0.032 in. (0.80 mm). If the spark plug fails any one of the conditions listed above, replace the plug. NOTICE Only use the recommended spark plug. See chart below.
MAINTENANCE 1-2019 4. Both the rocker arms should be loose at TDC on the compression stroke. If they are not, rotate the engine 360°. 5. Insert a feeler gauge between the rocker arm and the push rod and check for clearance (see Figure 21).
MAINTENANCE STORAGE WARNING Never store an inverter with fuel in the tank indoors or in a poorly ventilated area where the fumes can come in contact with an ignition source such as a: 1) pilot light of a stove, water heater, clothes dryer or any other gas appliance; or 2) spark from an electric appliance. NOTICE Gasoline stored for as little as 60 days can go bad, causing gum, varnish and corrosive buildup in fuel lines, fuel passages and the engine.
TROUBLESHOOTING 1-2019 WARNING Before attempting to service or troubleshoot the inverter, the owner or service technician must first read the owner’s manual and understand and follow all safety instructions. Failure to follow all instructions may result in conditions that can lead to voiding of the EPA certification or product warranty, serious personal injury, property damage or even death. PROBLEM Engine is running, but no electrical output.
