DANGER
Filling the fuel tank with fuel while the
generator is running can cause fuel
to spill and come in contact with hot
surfaces that can ignite the fuel.
Before starting the generator, always check the engine
oil and fuel levels.
After starting the generator, it is not safe to add fuel
to the fuel tank or engine oil to the engine while the
engine is running or immediately after stopping while
the engine and muffler are still hot.
Checking and Adding Engine Oil
!
WARNING
Internal pressure can build up in the
engine crankcase while the engine
is running. Removing the oil fill plug/
dipstick while the engine is hot can
cause extremely hot oil to spray out
of the crankcase and can severely
burn skin. Allow engine oil to cool for
several minutes before removing the
oil fill plug/dipstick.
The unit as shipped does not contain oil in the
engine. You must add engine oil before starting the
generator for the first time. See Checking Engine
Oil on page 30 and Adding Engine Oil on page
31 for instructions on checking engine oil level and
the procedure for adding engine oil.
NOTICE
The generator does not contain engine oil as
shipped. Attempting to start the engine before
adding engine oil can permanently damage internal
engine components.
Checking and Adding Fuel
!
WARNING
Never refuel the generator while the
engine is running.
Always turn the engine off and allow
the generator to cool before refuelling.
With the generator switched off and stationary on a
horizontal surface, check the fuel level as indicated on
the fuel gauge. It is good practice to always fill the fuel
tank before operating the generator.
Required Fuel – Use only unleaded petrol with an
octane rating not less than 87 and ethanol content not
greater than 10%. Where possible it is preferable to
use regular unleaded petrol without ethanol.
Filling the Fuel Tank – Follow the steps below to fill
the fuel tank:
1. Shut off the generator.
2. Allow the generator to cool down so all surface
areas of the muffler and engine are cool to the
touch.
3. Move the generator to a flat surface.
4. Clean area around the fuel cap.
5. Remove the fuel cap by unscrewing it anti-
clockwise.
6. Slowly add fuel into the fuel tank. Be very careful
not to overfill the tank. The fuel level should NOT
be higher than the bottom of the filler neck (see
Figure 13).
7. Replace the fuel cap by screwing it clockwise until
a click is heard, indicating the cap is completely
installed.

CAUTION

Avoid prolonged skin contact with
fuel. Avoid prolonged inhalation of
fuel vapours.
