    GENERATOR PREPARATION The following section describes the necessary steps to prepare the generator for use. If you are unsure about how to perform any of the steps please call 1-(800) 232-1195 M-F 8-5 CST for customer service. Failure to perform these steps properly can damage the generator or shorten its life. STEP 1 - ADD / CHECK OIL The generator is shipped without oil.
  • Page 12 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...
  • Page 13 GENERATOR PREPARATION STEP 2 - ADD / CHECK FUEL 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 14 GENERATOR PREPARATION STEP 3 - GROUND THE GENERATOR Fig. 7 To reduce the risk of electric shock and to maximize safety, the generator should be properly grounded. Ground the generator by tightening the grounding nut on the front control panel (Fig. 7) against a grounding wire. A gen- erally acceptable grounding wire is a No.
  • Page 15: Operation & Maintenance

    STARTING YOUR GENERATOR Before starting the generator, make sure you have read and performed the steps in the “Generator Preparation” section of this manual, page 11. If you are unsure about how to perform any of the steps in this manual please call 1-(800) 232-1195 M-F 8-5 CST for customer service.
  • Page 16 STARTING YOUR GENERATOR Before starting the generator, check the following: Fig. 8 1. Place the generator outside on a dry, level surface. Allow at least two feet of clearance on all sides of the generator. 2. Make sure all electrical devices are unplugged from the gen- erator during ignition.
  • Page 17: 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 18 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 19 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 (1800W) of the generator, DO NOT connect all these devices.
  • Page 20 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 included with your parallel connection kit for proper installation and operation.
  • Page 21 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 22: Shutting Off Your Generator

    OPTION 1: FUEL SHUT OFF (RECOMMENDED) The WEN 2250W 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.
  • Page 23: 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 24: Cleaning The Generator

    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...
  • Page 25 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 26 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 27 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 28: Spark Plug Maintenance

    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 29: Spark Arrestor Maintenance

    Replace the spark arrestor if it is damaged (replacement spark arres- tors can be purchased from wenproducts.com by search- ing the part no. 56225i-1509). 4. Reinstall the spark arrestor in the muffler and secure it in place with the screw.
  • Page 30: Transportation & Storage

    TRANSPORTATION & STORAGE TRANSPORTING THE GENERATOR To prevent fuel spillage when transporting, be sure to perform the following: 1. Tighten the fuel cap and turn the vacuum relief valve to “OFF”. 2. Set the engine switch to “OFF”. 3. Drain the fuel tank if possible (see “DRAINING THE FUEL TANK”). 4.
