Generator Operation

Before starting your generator, you should first place your generator on a firm, level surface. Make sure the generator is located outside, in a well-ventilated area and is kept dry. This is an important  safety feature as generators emit carbon monoxide which can be harmful.

Be sure to run your generator on a regular basis.  That way it will be ready to go when you need it most. At a minimum we recommend once a month. By running your generator on a monthly basis, you will recharge the battery (if the generator has an electric start function), run clean fuel though the carburettor and circulate oil in turn lubricating the engine.

Check List Before Operating your Generator:

  1. Take the generator outside to a well-ventilated area and place on a stable footing.
  2. Check the oil level and add oil if required.
  3. Check the fuel level. Add unleaded petrol or diesel (depending on the engine type) if needed.
  4. Do this outside in a well-ventilated area as the fuel tank cap works as a vent for the fuel tank during operation.
  5. Always use fresh fuel. Make sure you don’t use stale or dirty fuel. Dirt and water can cause you engine to malfunction.
  6. Prime the fuel to make sure fuel is pumped through to the carburettor and turn the choke on if needed.
  7. Check that the generator is grounded according to local regulations. See the advice of a local electrician if unsure.
  8. Plug lead into the electrical outlet on the generator.
  9. Check that any circuit breaker is in the off position before firing up the generator. Once the generator has warmed up you can switch on the circuit breaker.
  10. Turn on your appliance.

How to Stop your Generator:

  1. Turn the engine switch off.
  2. Shut off the fuel valve.

Generator Storage and Transportation

Before moving or storing your generator the most important item to check is the fuel value. Make sure it is in the off position. If the fuel value is left on, there is potential for fuel to get into the engine diluting the oil which can cause major damage to the engine. If you don’t intend to use your generator for a period of two months or more, you should drain the fuel from the carburettor.

Looking after your Generator

To ensure your generator serves you well for years to come, be sure to check the product manual for the regular servicing requirements, including oil change as demonstrated in the below video for an inverter generator:
