IMPORTANT SAFETY INSTRUCTIONS Before using this generator and if you have any questions regarding the hazard and safety notices listed in this manual and/or on this generator, call 1-800-832-2966, Monday - Friday, 9 AM - 6 PM Central Time. Carbon Monoxide Gas: When in operation, the exhaust from this generator contains poisonous carbon monoxide gas. Carbon monoxide gas is both odorless and colorless and may be present even if you do not see or smell gas.
Propane Safety: Propane gas (also known as LPG, or PG) is a flammable liquid gas under pressure which can form explosive mixtures with air, and cause other bodily harm if improperly handled. In case of inhalation: Persons suffering from lack of oxygen should be immediately moved to fresh air. If a victim is not breathing, administer artificial respiration. If breathing is difficult, administer oxygen. ALWAYS obtain medical treatment immediately for any breathing difficulties.

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 you are still unsure about how to perform any of these steps after reading this section, call 1-800-832-2966 Monday - Friday, 9 AM - 6 PM Central Time for customer service.
Step 2 – Fueling Add Unleaded gasoline only with an octane rating of 87 or higher. Maximum Capacity: 1.5 Gallons (MM2350 Series) 4 Gallons (MM4350 Series) 7.5 Gallons (MM9350 Series) Or attach a 20lb LPG cylinder using the supplied regulator assembly WARNING: YOU MUST USE THE SUPPLIED REGULATOR FOR SAFE OPERATION WHEN USING LPG AS THE FUEL SOURCE Step 3 - Ground the Generator Ground this generator by tightening the grounding nut against a grounding wire as illustrated in Figure 3.
Pre-Operation Check List Step 1 Check that the gasoline supply is in good condition, or check that the LPG inlet connection is secured tightly and not leaking. Turn the fuel valve to “on” for gasoline, or open the valve for LPG. Step 2 Make certain the CHOKE VALVE is at CHOKE (CLOSED) position. The generator may be hard to start if CHOKE VALVE is at the RUN (OPEN) position. Step 3 Ensure engine oil is full. Step 4 Make sure GROUND TERMINAL is properly grounded.
STARTING THE GENERATOR STOP! Before starting this correctly completed. If unsure about how to perform any of these steps, call 1-800-832-2966 Monday - Friday, 9 AM - 6 PM Central Time for customer service. Step 1 Step 2 Step 3 Step 4 Step 5 Make sure unleaded gasoline fuel has been added to the tank. Turn ENGINE SWITCH to the ON position. Move the CHOKE LEVER to CHOKE (Closed) position. For recoil start: Pull the STARTER GRIP slowly until resistance is felt and then pull rapidly.
Subsequent Use of this Generator For subsequent uses of this generator after the first use, certain steps still must be completed to prepare it for operation. of this manual. If not, review this section now. Step 1 - Verify 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 sufficient quantity. 1.
SOME NOTES ABOUT POWER CORDS Long or thin cords can require more wattage from a generator to power an electrical device. Figure 7 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.
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. NOTE: While this generator is running, power is available from either the standard 120 Volt outlets or the 12 Volt DC outlet. Both 120 Volts and 12V can be simultaneously drawn from this generator. 3.
DC USAGE To connect 12 Volt batteries to the DC outlet: 1. Connect the red charging wire to the positive terminal of the battery and the black charging wire to the negative terminal of the battery. If charging in a vehicle, always disconnect the vehicle’s ground cable first. 2. Connect the plug end of the wire to the 12V DC outlet on this generator. 3. Start this generator. 4.
CARBON MONOXIDE (CO) DETECTOR If you have purchased a MM2350C, MM2350DFC, MM4350C, MM4350DFC, MM9350EC, or MM9350DFEC Model it is equipped with a carbon monoxide (CO) Detector with an automatic shut-down system. The CO Detection module monitors for the accumulation of poisonous CO gas found in engine exhaust when the generator is running. If the CO Detector detects increasing levels of CO gas, it automatically shuts down the engine. CO detector only monitors for carbon monoxide when the engine is running.
MAINTENANCE/CARE Proper routine maintenance of this generator is essential for safe, economical, and trouble-free operation. It will help prolong the life of this generator as well as help reduce air pollution. Perform maintenance checks and procedures according to the schedule in Figure 10. It is recommended to use genuine Mech Marvels parts for any replacement needs. Use of non-Mech Marvels parts can damage or reduce the life of your generator.
Changing/Adding Oil The oil level in this generator should be checked before each use. When the oil level is low, add oil until the level is suff icient to operate this generator. To drain the oil from this generator: The oil should be changed after the first 20 hours of operation. The oil should then be changed every 6 months, or for every 100 hours of use time, or when it has become contaminated with water and/or dirt. Drain the oil while the engine is still warm to assure rapid and complete draining. 1.
Spark Plug Maintenenace 1. 2. 3. 4. 5. 6. 7. 8. Remove the spark plug cable from the spark plug. Using the spark plug tool that came with the generator remove the spark plug. Inspect the plug electrode. It must be clean and unworn to produce a proper spark for ignition. Check the spark plug gap. It should be set according to Table 1 After the plug is cleaned and gapped properly, reinsert back into the engine. Start threading the plug into the engine by hand to avoid cross threading.
Spark Arrester 1. 2. 3. 4. 5. 6. Allow the engine to cool completely before servicing the spark arrester. Remove the band clamp securing the arrester to the muffler. Remove the spark arrester screen. Carefully remove the carbon deposits from the spark arrester with a wire brush. Replace the arrester if damaged. Position the spark arrester in place on the muffler and re-secure with the band clamp.
