2. Safety Instructions
Operating a power generator requires careful attention to safety to prevent injury or damage. Always follow these guidelines:
- Carbon Monoxide Hazard: Never operate the generator indoors or in enclosed spaces. Exhaust fumes contain carbon monoxide, a colorless, odorless, and deadly gas. Ensure adequate ventilation when operating outdoors.
- Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator. Store fuel in approved containers away from heat sources.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded. Never touch live electrical parts.
- Hot Surfaces: The engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact to prevent burns.
- Moving Parts: Keep hands, feet, and clothing away from moving parts such as the fan and flywheel.
- Children and Pets: Keep children and pets away from the generator at all times.
- Grounding: Always properly ground the generator before operation to prevent electrical shock.

4.2 Adding Engine Oil
The engine is shipped without oil. Operating without oil will cause severe engine damage.
- Place the generator on a level surface.
- Remove the oil filler cap/dipstick.
- Add the recommended engine oil (refer to engine manual for specific type and quantity, typically SAE 10W-30 or 10W-40) until it reaches the upper mark on the dipstick. Do not overfill.
- Securely replace the oil filler cap/dipstick.
4.3 Adding Fuel
Use unleaded gasoline (ROZ95) only. Never use E85 or mixed fuels.
- Ensure the engine is off and cool.
- Move the generator to a well-ventilated outdoor area.
- Unscrew the fuel tank cap.
- Carefully fill the fuel tank, avoiding overfilling. Leave some space for fuel expansion.
- Securely replace the fuel tank cap. Wipe up any spilled fuel immediately.
4.4 Grounding the Generator
For safety, the generator must be properly grounded.
- Connect a heavy-gauge wire from the generator's grounding terminal to an earth ground rod.
- Consult local electrical codes for proper grounding procedures.
5. Operating Instructions
Follow these steps for safe and effective operation.
5.1 Starting the Engine
- Ensure the generator is on a level surface and properly grounded.
- Turn the fuel valve to the 'ON' position.
- Move the choke lever to the 'CHOKE' position (cold engine).
- Turn the engine switch to the 'ON' position.
- Pull the recoil starter handle firmly and smoothly until the engine starts. Do not let the rope snap back.
- Once the engine starts, gradually move the choke lever to the 'RUN' position.
