GENERATOR COMPONENTS Observe the locations and functions of the various components and controls of this generator. WARNING: YOU MUST USE THE SUPPLIED REGULATOR FOR SAFE OPERATION To prevent electrical shock from faulty appliances, the generator should be grounded. Connect a length of heavy wire between the ground terminal and the ground source. Consult with a qualified electrician to ensure compliance with local electrical codes. ATTENTION: The Air-fuel Mixer is not adjustable.
PREPARING THE GENERATOR FOR USE Using this Generator for the First-Time STOP! The following section describes the required steps for preparing this generator for the first use. Failure to correctly perform these steps can damage this generator and/or shorten its life. If still unsure about how to perform any of these steps after reading this section, call 1-866-460-9436 Monday - Friday, 8 AM - 4 PM Central Time for customer service.
Step 2 – Connect Fuel Sulfur, water, dust, etc. are harmful for engine. If the gas supply source (LPG) contains these harmful elements, user must use filter to remove sulfur, water etc. and clean gas. Otherwise, the engine service lifetime will be shortened. Choose either LPG or Gasoline fuel. If using LPG, first connect the regulator that was included with the generator to Propane Fuel Tank, then connect the other end to the Gas Inlet.
Step 3 - Ground the Generator Failure to properly ground this generator can result in electrocution. Ground this generator by tightening the grounding nut against a grounding wire as illustrated in Figure 3. A No. 12 AWG (American Wire Gauge) stranded copper wire is generally an acceptable grounding wire. The other end of this grounding wire should be connected to a copper or brass grounding rod that is driven into the earth. Grounding codes can vary by location.

USING THE GENERATOR After the engine has been running for several minutes, electrical devices may be connected to this generator. AC Usage Electrical devices running on AC current may be connected according to their wattage requirements. The rated (running) and surge wattage: Model GEN7500DF-SS Rated (Running) Wattage Model GEN7500DF-SS Surge Wattage 6000 7500 The rated (running) wattage corresponds to the maximum wattage a generator can output on a continuous basis.
Connect electrical devices to this generator according to the following procedure: 1. Allow the engine to run for several minutes after it has been started. 2. Confirm that the electrical device is switched off prior to plugging it into this generator. Connect only electrical devices that are in good working order. Faulty devices or power cords present the risk of electrical shock. Immediately turn off and disconnect any device that commences to operate abnormally, sluggish or abruptly stops.
SOME NOTES ABOUT POWER CORDS Long or thin cords can require more wattage from a generator to power an electrical device. Figure 9 shows the recommended cords according to the power requirement of the electrical device. When using cords that exceed these specifications, allow for the electrical device to have a slightly higher rated wattage requirement. Device Requirements Amps Watts (120V) 2.5 300 5 600 7.5 900 10 1200 15 1800 20 2400 25 3000 30 3600 40 4800 NR = Not Recommended.
STOPPING THE GENERATOR To stop this generator: 1. Turn off all connected electrical devices and then unplug them. 2. Allow this generator to run for several more minutes with no electrical devices connected to help stabilize the temperature of this generator. 3. Turn off the engine switch. 4. If using Propane, turn the propane tank fuel valve to the “off” position. Allow this generator to cool down before touching areas that become hot during operation.
Checking the Oil Level Even though this generator is equipped with an automatic shutoff to protect it from damage due to low oil, it is important to check the oil level in the engine crankcase before each use to ensure that there is a sufficient quantity. To check the oil level: 1. Verify that this generator is shut down and on a level surface. 2. Unscrew the oil filler/dipstick cap from the engine as illustrated in Figure 11. 3.
Model GEN7500DF-SS Oil Capacity Model GEN7500DF-SS Oil Type Recommended 38 ounces High Detergent Motor Oil, SAE10W-30 Figure 12 - Draining Oil Figure 13 - Adding Oil Air Filter Maintenance Occasionally verify that the air filter is free of excessive dirt. The air filter will require more frequent cleaning when operating this generator in extremely dusty areas. 1. Unhinge the clasps at the top and bottom of the air filter cover as shown in Figure 14. 2. Remove the sponge-like elements from the casing. 3.
STORAGE/TRANSPORT PROCEDURES Never place any type of storage cover on this generator while it is still hot. When transporting or storing this generator for extended time: • Allow generator to fully cool before moving it. A hot engine and exhaust system can burn you and ignite some materials. • Disconnect the battery used for the electric start feature of this generator, first disconnecting the black cable and then the red cable. • Turn the fuel valve to the “off” position. • Disconnect the spark plug.
TROUBLESHOOTING IMPORTANT: If trouble persists, call our customer help line at 1-866-460-9436, Monday - Friday, 8 AM - 4 PM Central Time. Symptom Engine will not start. Generator runs but does not support all connected electrical devices. Cause Solution Fuel valve is turned to "closed." Choke is open. Propane Tank is out of fuel. Turn fuel valve to "open." Close the choke. Replace propane fuel tank. Spark plug is dirty. Clean spark plug. Generator is not on level surface.
