FAQs

Is this generator safe for my laptop?

Yes, because the SG3500i uses inverter technology to produce a pure sine wave, it is safe for sensitive electronics like laptops and TVs.

How loud is the generator while running?

The generator operates at approximately 66dB, which is relatively quiet for a 3000W generator and suitable for most outdoor settings.

Can I use this indoors?

No. Never run a petrol generator indoors or in confined spaces, as the exhaust contains carbon monoxide, which is deadly.

What type of oil should I use?

Please refer to the user manual provided with your specific unit for the recommended oil viscosity and type.

How often should I change the oil?

It is recommended to perform the first oil change after the initial break-in period, followed by regular intervals as specified in the maintenance schedule of the manual.

What is the maximum output?

The SG3500i provides a rated power output of 3000W.

Troubleshooting

Generator fails to start

Check fuel levels, ensure the engine switch is in the 'On' position, and verify the spark plug cable is securely connected.

Engine runs but no power output

Check if the circuit breaker has tripped; if so, disconnect the load and reset the breaker.

Generator shuts down unexpectedly

Check the oil level; the low-oil sensor will automatically shut off the unit to prevent damage.
