4. Setup

Before starting the generator for the first time, perform the following setup steps.

1. Unpacking and Placement:
   • Remove the generator from its packaging.
   • Place the generator on a firm, level surface in a well-ventilated outdoor area, away from windows, doors, and vents.
   • Ensure there is at least 1 meter (3 feet) of clear space around the generator for proper ventilation.
2. Add Engine Oil:
   • Locate the oil fill cap/dipstick.
   • Add the recommended diesel engine oil (refer to specifications for type and capacity) until it reaches the upper mark on the dipstick. Do not overfill.
   • Securely replace the oil fill cap.
3. Add Diesel Fuel:
   • Ensure the engine is off and cool.
   • Open the fuel tank cap.
   • Fill the fuel tank with clean, fresh diesel fuel. Do not overfill; leave some space for expansion.
   • Securely replace the fuel tank cap.
4. Connect Battery (if not pre-connected):
   • Connect the positive (+) battery cable (red) to the positive (+) terminal on the battery.
   • Connect the negative (-) battery cable (black) to the negative (-) terminal on the battery.
   • Ensure connections are tight.
5. Grounding:
   • Connect a grounding wire from the generator's grounding terminal to a suitable earth ground (e.g., a ground rod).

5. Operating Instructions

Follow these steps for safe starting and stopping of your generator.

5.1. Starting the Engine

1. Ensure all electrical loads are disconnected from the generator.
2. Check engine oil and fuel levels.
3. Turn the fuel valve to the "ON" position.
4. If equipped, set the choke lever (if cold start is needed).
5. Insert the key into the key switch and turn it to the "START" position. Release the key once the engine starts. Do not hold the key in the "START" position for more than 5 seconds.
6. Allow the engine to warm up for a few minutes before connecting any loads.
7. Once the engine is running smoothly, if the choke was used, gradually move it to the "OFF" position.

5.2. Connecting Electrical Loads

1. Ensure the generator is running stably.
2. Plug your appliances into the AC outlets.
3. Do not exceed the generator's rated wattage (6000W continuous, 6300W max). Overloading will trip the circuit breakers.
4. Connect appliances one at a time, starting with the largest load.

5.3. Stopping the Engine

1. Disconnect all electrical loads from the generator.
2. Allow the generator to run for a few minutes without load to cool down.
3. Turn the key switch to the "OFF" position.
4. Turn the fuel valve to the "OFF" position for storage.
5. In an emergency, press the E-STOP button to immediately shut down the engine.

6. Maintenance

Regular maintenance is crucial for the longevity and reliable operation of your generator.

6.1. Daily/Before Each Use

• Check engine oil level.
• Check fuel level.
• Inspect for any visible damage, leaks, or loose fasteners.

6.2. Every 50 Hours or Monthly

• Change engine oil.
• Clean or replace air filter.
• Check battery terminals for corrosion and tightness.

6.3. Every 200 Hours or Annually

• Inspect and clean fuel filter.
• Inspect and adjust valve clearance (recommended to be done by qualified service personnel).
• Check fuel lines and connections for wear or damage.
• Clean spark plug (if applicable, though diesel engines use glow plugs for starting).

Always refer to the engine manufacturer's manual for detailed maintenance schedules and procedures.
