MAINTENANCE
Draining tHE FuEl
Occasionally it may be necessary to drain all of the
fuel out of the generator. For example, to remove
contaminated or stale fuel or to prepare the generator
for transport or storage.
Tools required (not included) – 10 mm spanner,
funnel and fuel storage container
.
1. Turn the fuel shutoff valve to the ON position
(see Figure 15).
2. Clean the fuel strainer (see Fuel Strainer
Maintenance on page 34).
3. Position the funnel and fuel storage container
under the carburettor drain screw and then remove
the screw by turning it anti-clockwise with the
spanner (see Figure 52 or 53, as appropriate).
4. Carefully drain the fuel into the storage container.
Take care to wipe up any spills immediately.
5. When all of the fuel has been drained out, re-
install the carburettor drain screw by turning it
clockwise by hand first, and then finish tightening
it with the spanner. Move the funnel, storage
container and any fuel soaked rags away from the
generator. It is preferable to consume the fuel in
another engine-powered device straight away or
dispose of it properly rather than storing it for a
long time with fuel stabilizer for later re-use.
6. Turn the fuel shutoff valve to the OFF position
and then clean the fuel sediment cup (see Fuel
Sediment Cup Maintenance on page 35).
NOTICE
Never dispose of fuel or fuel contaminants by
dumping either of them into a sewer, on the ground,
or into groundwater or waterways. Always be
environmentally responsible. Follow the guidelines
of the governmental agencies for proper disposal
of hazardous materials. Consult local authorities or
reclamation facility.

WARNING
Never store a generator with fuel
in the tank indoors or in a poorly
ventilated area where the fumes can
come in contact with an ignition
source such as: a pilot light of a stove,
water heater, clothes dryer or any
other gas appliance; or a spark from
an electric appliance.
NOTICE
Fuel stored for as little as 30 days can go bad,
causing gum, varnish and corrosive build-up in fuel
lines, fuel passages and the engine. This corrosive
build-up restricts the flow of fuel, preventing an
engine from starting after a prolonged period of
storage.
The most commonly experienced faults with
portable generators are directly attributable to stale
fuel. Such faults are not covered by the generator’s
warranty.
The generator should be run at least once per month
for 30 minutes under no less than one-third of full
load. If this is not possible, the generator should
be prepared for long-term storage as described
hereunder.
