3. Setup and Preparation
3.1 Unpacking and Inspection
Carefully remove the generator from its packaging. Inspect for any damage that may have occurred during shipping. If any damage is found, contact your dealer immediately.
3.2 Placement
Place the generator on a firm, level surface. Ensure there is adequate clearance around the unit for proper ventilation and to prevent heat buildup. Keep it at least 1 meter (3 feet) away from buildings or other equipment.
3.3 Adding Engine Oil
The generator is shipped without engine oil. Before first use, add the recommended engine oil (e.g., SAE 10W-30) to the crankcase. Refer to the oil fill cap or dipstick for the correct level. Do not overfill.

3.4 Adding Fuel
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Fill the fuel tank carefully, avoiding spills. Do not fill above the red indicator or the bottom of the filler neck. Securely close the fuel cap after filling.
- Always refuel in a well-ventilated outdoor area.
- Ensure the engine is off and cool before refueling.
- Do not smoke or use open flames near the generator.
3.5 Grounding the Generator
For safety, the generator must be properly grounded. Connect a heavy-gauge copper wire from the generator's grounding terminal to an earth ground rod or other approved grounding source. Consult local electrical codes for specific requirements.
5. Maintenance
Regular maintenance is crucial for the longevity and reliable operation of your generator. Always ensure the engine is off and cool before performing any maintenance.
