INTRODUCTION Thank you for purchasing a WEN Generator. This manual provides information regarding the safe operation and maintenance of this product. Every effort has been made to ensure the accuracy of the information in this manual. WEN reserves the right to change this product, manual and specifications at any time without prior notice. Please keep this manual available to all users during the entire life of the generator.
SAFETY INFORMATION For any questions regarding the hazard and safety notices listed in this manual or on the product, please call (800) 232-1195 M-F 8-5 CST before using the generator. DANGER: CARBON MONOXIDE Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
SAFETY INFORMATION GENERATOR SAFETY RULES (CONTINUED): 14) Do not touch hot surfaces. Pay attention to warning labels on the generator identifying hot parts of the machine. 20) Do not exceed the wattage capacity of the generator by plugging in more electrical devices than the unit can handle. 15) Allow generator to cool down after use before touching engine or areas of the generator that become hot during use. 21) Do not turn on electrical devices until after they are connected to the generator.
GENERATOR COMPONENTS Use the illustrations below to become familiar with the locations and functions of the various components and controls of this generator.
GENERATOR PREPARATION USING THE GENERATOR FOR THE FIRST TIME CAUTION: The following section describes the necessary steps to prepare the generator for use. If after reading this section, you are unsure about how to perform any of the steps please call (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 OIL The generator is shipped without oil.
GENERATOR PREPARATION WARNING: 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. Step 2 - ADD GASOLINE Use fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. Do not mix oil with gasoline. Adding a fuel stabalizer will help prolong the storage life of the gasoline. To add gasoline, follow these steps: 1.
STARTING THE GENERATOR Before starting the generator, make sure you have read and performed the steps in the “Generator Preparation” section of this manual. If you are unsure about how to perform any of the steps in this manual please call (800) 232-1195 M-F 8-5 CST for customer service. DANGER: CARBON MONOXIDE - USING A GENERATOR INDOORS CAN KILL YOU IN MINUTES. Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell.
STARTING THE GENERATOR STARTING THE ENGINE (FIG. 4) To start the generator, perform the following steps: 1. Unplug all electrical devices from the generator before starting. Otherwise it can be difficult to start the engine. 2. To maximize safety, make sure the generator is properly grounded (Refer to “Ground the Generator” on page 9). Fig. 4A 3. Check the oil and fuel levels. 4. Turn the ECO-MODE switch to “OFF” (Fig. 3). 5. Open pressure relief valve on top of fuel cap (Figure 4A).
STOPPING THE GENERATOR TO STOP THE GENERATOR 1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause damage to the generator. After turning the devices off, unplug them all from the generator. 2. Turn the 3-in-1 knob to the “OFF” position (Fig. 4E). 3. Close the pressure relief valve on top of gas cap (Fig. 4A). Rotate counterclockwise to the “OFF” position.
SUBSEQUENT STARTING OF THE GENERATOR Step 3 - GROUND THE GENERATOR WARNING: Failure to properly ground the generator increases the chances of electric shock. Ground the generator by tightening the grounding nut on the front control panel against a grounding wire (Fig. 3). A generally acceptable grounding wire is a No. 12 AWG (American Wire Gauge) stranded copper wire. This grounding wire should be connected at the other end to a copper, brass, or steel-grounding rod that is driven into the earth.
USING THE GENERATOR If the electrical specifications are not available for your electronic devices, estimate the watts requirement of the device by using the chart in Figure 6. 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 of the generator, DO NOT connect all these devices.
USING THE GENERATOR CAUTION: Do not connect 50Hz loads to the 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. See Figure 7 for recommended cords based on the power requirement of the electrical device. Device Requirements Amps Watts (120V) 2.5 300 5 600 7.5 900 10 1200 *NR = Not Recommended Max.
MAINTENANCE & CARE CLEANING THE GENERATOR Never clean the generator when it is running! Never clean with a bucket of water or a hose. Water can get inside the working parts of the generator and cause corrosion or a short circuit. Always try to use the generator in a cool, dry place. If the generator becomes dirty, clean the exterior with a damp cloth, a soft brush, a vacuum or pressurized air. CHECKING THE OIL Check the oil level of the generator according to the Recommended Maintenance Schedule in Fig. 9.
MAINTENANCE & CARE 3. Tilt the generator so the used oil flows from the engine into the container. Tilt some more to ensure all oil is out of the crankcase. 4. Return the generator to its upright and level position. Fill the crankcase with fresh oil and reinstall the oil plug. Clean any oil spillage before closing the side panel. TO REFILL THE CRANKCASE WITH OIL: 1. Make sure the generator is on a level surface.
MAINTENANCE & CARE SPARK PLUG MAINTENANCE (Fig. 11) The spark plug is important for proper engine operation. A good spark plug should be intact, free of deposits, and properly gapped. Refer to Recommended Maintenance in Figure 8 (p. 15). To inspect the spark plug: 1. Open the spark plug access panel at the top of the generator using the aid of a coin. 2. Remove spark plug boot. Be careful not to tear insulation or wire. 3. Unscrew the spark plug from the engine using the spark plug wrench provided.
MAINTENANCE & CARE DRAINING THE CARBURETOR After each use, open up the carburetor drain with a screwdriver and drain out any gasoline that has built up inside. Once the fuel has drained, close the drain back up with the same screwdriver. It is best to do this after every use and required before storing the generator for long periods of time. The location of the carburetor can be found in Fig. 12. Carburetor Fig. 12 SPECIFICATIONS USB Charger DC Output 5V, 1A (left) / 5V, 2.
