Storage; Disposal - GMC GGEN700 Manual

Draining the fuel tank
Note: This may be necessary for storage or transport, or if you
experience starting difficulties due to contaminated fuel.
1. Switch off the Fuel Shut-Off Valve (11)
2. Remove the rubber fuel hose from where it connects to the
carburettor
Note: Use suitable pliers (not included) to decompress and
push aside the hose clip.
3. Place the end of the fuel hose into a suitable container, e.g.
a bowl or fuel bottle
4. Open the Fuel Shut-Off Valve, and let the petrol drain from the Fuel Tank (2) into the
GB
container
5. Close the Fuel Shut-Off Valve when finished, reconnect the fuel hose to the carburettor and
refit the hose clip
WARNING: Always check for leaks after disconnecting/reconnecting fuel lines.

Storage

WARNING: Ensure the Engine Switch (8) is in the 'OFF' position, and the Fuel Shut-Off Valve
(11) shut, before transporting or storing the generator.
Transporting the generator
This generator provides a Carrying Handle (5) on top of the fuel tank
Keep the generator level to prevent fuel spillage
WARNING: Spilled fuel or fuel vapours may ignite and lead to fire and explosions. Clean up
spilled fuel or oil immediately, to prevent it from entering the environment.
Storing the generator
Store carefully in a secure, dry place out of the reach of children
If storing long-term, drain the entire fuel system as described in 'Draining the fuel tank' and
'Draining the carburettor'
Preparation for long-term storage
Whenever the machine is out of use for an extended period of time, proceed as follows:
1. Give the unit an overall cleaning and a thorough check
2. Clean the air filter as described in 'Cleaning or changing the
air filter'
3. Drain the fuel system as described in 'Draining the fuel tank'
and 'Draining the carburettor'
4. Remove the Spark Plug Cap (14) and Spark Plug (15), fill
about a spoonful of 2-stroke oil into the cylinder through the
spark plug hole, and pull the recoil starter gently two to three
times to distribute the oil evenly. Replace the Spark Plug and
Spark Plug Cap
5. Slowly pull the Recoil Starter Cord (10) just until resistance
is felt. At this point, the piston is coming up on its compression stroke, and both the intake
and exhaust valves are closed. Storing the engine in this position will help prevent internal
corrosion
6. Protect all metal parts from corrosion by coating them with oil or a machinery preservative
Storing fuel
• Store 2-stroke mix ONLY in containers specifically designed for fuel storage
• Store fuel in a dark place with a constant, low temperature
WARNING: Petrol degrades during storage, altering its quality very quickly. Keep only the
minimum amount of fuel required for your immediate consumption. Old fuel will cause starting
difficulties, may clog fuel lines and damage the carburettors and engines.

WARNING: If storing fuel on domestic premises, refer to local regulations about permitted
quantities and required containers.

WARNING: NEVER dispose of old or polluted fuel with household waste, or pour into the
ground, sewers or rainwater drains. Fuel is a major pollutant and must be recycled according
to local laws and regulations. Place fuel in a sealed, hydrocarbon-proof container, and take it
to your local recycling centre.
Note: Engine damage caused by old or polluted fuel is NOT covered by warranty.

Disposal

Always adhere to national regulations when disposing of power tools that are no longer
functional and are not viable for repair.

Storing petrol and 2-stroke mix in sealed containers:
Volatile fuels such as petrol and 2-stroke mix will store for up to one year in a sealed
container
After that period the fuel may still be fit for purpose, but problems such as hard starting
and spark plug fouling may occur due to lack of light components
Once the seal is broken, lighter components evaporate and the storage life is best
assumed to be 6 months at ambient temperatures of 20°C, and 3 months or less at
ambient temperatures of 30°C or more
Storing petrol and 2-stroke mix inside equipment:
Petrol and 2-stroke mix in a fuel tank is exposed to the air and lighter components will
readily evaporate. As a result, the fuel becomes heavier and will cause hard starting,
spark plug fouling, rough running and misfiring. Not all of the fuel in this heavier air/fuel
mix can be completely burnt, leaving deposits in the combustion chamber
Petrol and 2-stroke mix which has been in the equipment tank for more than 2 weeks
should be used with caution, and should be freshened with an equal volume of new fuel
to restore volatile components and reduce fouling issues
Keeping equipment fuel tanks one-third full stops moisture from getting into the fuel tank
and leaves room to add fuel to freshen the mix. However, safety concerns need to be
addressed when storing equipment tanks partially full while not in use
Petrol that has been kept in the equipment tank for several months should be discarded
and not be used
Do not dispose of power tools, or other waste electrical and electronic equipment
(WEEE), with household waste
Contact your local waste disposal authority for information on the correct way to dispose
of power tools
Tools powered by petrol-based internal combustion engines must not be disposed of with
household waste. Such tools should be taken to your local recycling centre and disposed
of according to current environmental protection requirements in your country
Petrol, oil and petrol-oil-mixtures are hazardous waste and have to be treated as such.
Oil and fuel must not be disposed of with household waste. Improper disposal may be
regarded a criminal offence in your country. Contact your local authority or dealer for
correct disposal procedures for oil and old fuels
