  • Page 13 Indicator TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included), available for purchase at wenproducts.com. The dipstick’s industrial-strength magnetic tip will collect metal shavings from your generator’s oil tank to help preserve the engine and extend your generator’s lifespan.
  • Page 14 GENERATOR PREPARATION STEP 2 - ADD / CHECK FUEL FUEL OPTION A: GASOLINE WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead to explosion even if not directly in contact with gasoline.
  • Page 15 If bubbles appear, become larger in size, or increase in number, a leak exists. This MUST be corrected before using generator. Contact WEN customer service at 1-800-232- 1195, M-F 8-5 CST, or email techsupport@wenproducts.com for as- sistance.
  • Page 16 GENERATOR PREPARATION AUTO FUEL SELECTION Your generator is equipped with Auto Fuel Selection Technology. What this means is that the generator will auto- matically select the fuel source (LPG or gasoline) depending on availability. LPG is prioritized; this means that if a propane tank with enough LPG is connected, the generator will automatically use LPG.

  • Page 21: Using Your Generator

    USING YOUR GENERATOR CALCULATING THE WATTAGE OF YOUR DEVICE(S) Connect electrical devices running on AC current according to their wattage requirements. Calculate the total run- ning wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the capacity of your generator and the capacity of each individual outlet.
  • Page 22 USING YOUR GENERATOR CALCULATING THE WATTAGE OF YOUR DEVICE(S) - CONTINUED The chart below serves as a reference for the estimated wattage requirements of common electrical devices. How- ever, do not solely rely on this chart - all electronics and appliances are built differently. Always check the wattage listed on the electrical device before consulting this chart.
  • Page 23 USING YOUR GENERATOR CONNECTING ELECTRICAL DEVICES When the rated wattage requirement of each electrical device has been determined, add these numbers to find the total rated wattage needed. If this number exceeds the rated wattage (2000W gasoline, 1800W LPG) of the genera- tor, DO NOT connect all these devices.
  • Page 24 1500W / 1350W. PARALLEL OPERATION The parallel connection ports allow you to connect two WEN generators to increase the total available electrical power. The WEN Parallel Connection Kit can be purchased from wenproducts.com. Follow the instructions in- cluded with your parallel connection kit for proper installation and operation.
  • Page 25 USING YOUR GENERATOR SOME NOTES ABOUT POWER CORDS Long or thin cords can drain the power provided to an electrical device by the generator. When using such cords, allow for a slightly higher rated wattage requirement by the electrical device. Device Requirements Max.

  • Page 27: Shutting Off Your Generator

    OPTION 1A: AUTOMATIC FUEL SHUTOFF (RECOMMENDED – GASOLINE ONLY) The WEN 2500W Inverter Generator is equipped with automatic fuel shutoff. This feature turns off the flow of fuel, allowing for the generator to use up the remaining fuel from the carburetor before turning off. This prolongs the lifespan of the generator by preventing build-up and blockages caused by stagnant fuel inside of a carburetor.
  • Page 28 SHUTTING OFF THE GENERATOR CAUTION! Unplugging running devices can cause damage to the generator. Never stop the engine with elec- trical devices connected and running. OPTION 2: MANUAL SHUTOFF In case you are in a hurry and do not want to wait for the generator to automatically shut down, the manual shutoff feature is available.

  • Page 29: Maintenance

    MAINTENANCE Proper routine maintenance of the generator will help prolong the life of the machine. Please perform maintenance checks and operations according to the schedule in Table 4. CAUTION! Never perform maintenance operations while the generator is running. Before maintaining or servicing the generator, turn OFF the generator, disconnect all devices and allow the generator to cool down.
  • Page 30 TIP: Your WEN generator is compatible with the WEN 55201 Magnetic Oil Dipstick (not included), available for purchase at wenproducts.com. The dipstick’s industrial-strength magnetic tip will collect metal shavings from your generator’s oil tank to help preserve the engine and extend your generator’s lifespan.
  • Page 31 MAINTENANCE DRAINING THE CARBURETOR We recommended draining the carburetor after every use (not necessary if the generator is shut off using the “FUEL OFF” option), and before storing the generator. Draining the carburetor can prevent the fuel from clogging up the carburetor and preventing the generator from starting. 1.
  • Page 32 MAINTENANCE AIR FILTER MAINTENANCE Check every 50 hours of operation (refer to Table 4 - Recommended Maintenance Schedule). Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air cleaner is free of excessive dirt. To inspect and clean the air filter: Fig.
  • Page 33 MAINTENANCE DRAINING/CHANGING OIL Change the oil according to the Recommended Maintenance Schedule in Table 4. Change the oil MORE OFTEN if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. Changing the oil when the engine is warm allows for complete drainage.
  • Page 34 MAINTENANCE SPARK PLUG MAINTENANCE Refer to Recommended Maintenance Schedule in Table 4 for maintaining the spark plug. The spark plug is important for proper engine operation. Check the spark plug regularly to maintain proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. To inspect or replace the spark plug: Fig.
  • Page 35 MAINTENANCE SPARK ARRESTOR MAINTENANCE Inspect and clean the spark arrestor every 100 hours of operation. The spark arrester is located outside the muffler, which gets very hot during operation. Allow the engine to cool completely before servicing the spark arrester. To inspect and clean the spark arrester: 1.
