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. User must add the proper amount of oil before operating the generator for the first time.
GENERATOR PREPARATION For subsequent operation, the oil level should be checked before each use, or after every 8 hours of operation. The generator is equipped with a low-oil sensor and will NOT start without a sufficient amount of oil. Fig. 4 To check oil level (before every subsequent start): 1. Place the generator on a level surface. Make sure the engine is OFF before adding or checking oil. 2. Open the oil access cover. Remove and wipe the dipstick with a clean rag. 3.
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. • Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator. • Always operate on a firm, level surface. • Always turn generator off before refueling.
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 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.
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. 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.
STARTING YOUR GENERATOR Before starting the generator, check the following: 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 generator during ignition. Otherwise it will be difficult for the engine to start. Fig. 8 OFF RUN 2 CHOKE 3. To maximize safety, check that the generator is properly grounded (see “GROUND THE GENERATOR” section). MANUAL SHUT OFF 4.
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 running 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.
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. However, 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.
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. Select a combination of electrical devices with a total rated wattage lower than or equal to the rated wattage of the generator. CAUTION! Become familiar with the markings on the control panel (Fig.
USING YOUR GENERATOR ECO-MODE SWITCH This generator is equipped with an Eco-Mode Idle Control Switch. Engaging this switch allows the system to regulate the engine speed and automatically adjust its fuel consumption to match the required load. When the electrical load changes, the generator engine will automatically speed up and slow down as needed. This reduces fuel consumption and noise levels, while extending runtime and engine’s lifespan.
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 Amps 2.5 5 7.5 10 15 20 25 30 40 Watts (120V) 300 600 900 1200 1800 2400 3000 3600 4800 *NR = Not Recommended Max.
SHUTTING OFF YOUR GENERATOR CAUTION: Unplugging running devices can cause damage to the generator. Never stop the engine with electrical devices connected and running. 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.
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.
MAINTENANCE CLEANING THE GENERATOR Keep the generator clean to prevent improper operation or machine damage from dirt and debris. Inspect all ventilation openings on the generator. These openings must be kept clean and unobstructed. If the generator becomes dirty, use a damp cloth to wipe exterior surfaces. Use a soft bristle brush to loosen dirt and oil and use a vacuum to pick up loose dirt. Use low pressure air (not to exceed 25 PSI) to blow away dirt.
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. Place generator on elevated platform such as table or desk. Fig. 15 2.
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: 1. Using a Phillips-head screwdriver (not included), remove the service panel by unscrewing the three Phillips-head screws (Fig. 15) along the upper edge. Fig. 18 2.
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. 1. Close the gas cap and vacuum relief valve. 2.
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: 1. Using a Phillips-head screwdriver (not included), remove the service panel by unscrewing the three Phillips-head screws along the upper edge.
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. Remove the screw that secures the spark arrestor to the muffler. Fig. 22 2. Remove the spark arrestor screen (Fig. 22). 3.
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. Keep the generator upright. Never place the generator on its side or upside down - doing so will make it difficult to start. WARNING: Avoid direct sunlight inside a vehicle.
