Fuel Tank
As is common with all plastic fuel containers, the
removable fuel tank supplied with this generator may swell
or expand due to build-up of fuel vapors when the vent
knob is closed.This tank is designed and has been tested to
safely withstand pressure-buildup.The 'ballooning' condition
is relieved by turning the vent knob fully counterclockwise
or loosening and retightening the fuel cap/gauge.When
installing the tank on your generator, relieve tank pressure
before tightening the four large plastic wing nuts.
IMPORTANT: The vent knob should be closed whenever
you move the generator or transport the fuel tank.
1. Turn the vent knob fully clockwise on the fuel gauge to
close it (Figure 4).

IMPORTANT: The fuel tank MUST be filled with it lying flat,
not slanted or standing upright (Figure 9). DO NOT let the
fuel valve and quick connect come in contact with any dirt.

To place the fuel tank back on the unit, follow these same
steps in reverse order. Make sure the four large plastic
wing nuts are tightened securely.
IMPORTANT: Remove any dirt found inside the quick
connect before putting the fuel tank back on the unit.
Make sure the vent knob is turned fully counter-
clockwise to open it. If you don't open it, fuel will not
flow into the fuel line causing the unit to not start.
