Preparing 2-stroke mix
Note: This generator is powered by a 2-stroke engine that
requires a petrol/oil mixture as fuel.
WARNING: ALWAYS use dedicated 2-stroke oil. DO NOT use
regular engine oil for 2-stroke mix.
1. Open the Fuel Cap (6) and remove the 2-Stroke Oil
Measuring Cup (13) from the Fuel Mesh Filter (12) inside
the fuel tank
2. Use the 2-Stroke Oil Measuring Cup to measure the
required amount of oil (see 'Specification' for fuel-to-oil
ratio), and pour into a suitable mixing container (e.g. a petrol jerry can)
WARNING: DO NOT pour oil directly into the Fuel Tank (2). The 2-stroke mix needs to be
prepared and thoroughly mixed in a separate container, prior to being filled into the generator.
3. Pour the required amount of unleaded petrol into the container, close and shake until
thoroughly mixed
Note: 2-stroke mix must not be stored long-term. ONLY mix the amount required for
immediate consumption. Refer to the 'Storing Fuel' section for further information.
Filling with fuel
WARNING: NEVER fill with fuel whilst the engine is running. Switch off the engine and wait
until it has cooled before refuelling.
WARNING: ONLY use petrol/oil mixtures (2-stroke mix) with
this generator. NEVER use neat petrol, as this will quickly lead
to overheating and permanent engine damage.
WARNING: In some regions petrol may contain a percentage
of alcohol (ethanol or methanol). Using such fuels with this
generator is not recommended. Fuels containing more than
10% ethanol MUST NOT be used under any circumstances. If
using fuels containing methanol, specific corrosion inhibitors
must be added, and the proportion of methanol MUST be kept
below 5%. Damage to the fuel system or engine caused by fuels containing alcohol are not
covered by warranty.
Note: For further advice on fuel, also refer to 'Storing Fuel' in the 'Maintenance' section of
this manual.
1. Ensure the Fuel Shut-Off Valve (11) is in the 'OFF' position
(vertical)
2. Open the Fuel Cap (6) by turning it anticlockwise until the
bayonet disengages, and remove
3. Fill the Fuel Tank (2) with fresh unleaded fuel (see
'Specification'), until the fuel level reaches the top of the
Fuel Mesh Filter (12) inside the fuel tank opening. DO NOT
overfill

All manuals and user guides at all-guides.com
Note: Whilst refuelling, petrol must be poured through the Fuel Mesh Filter into the tank. DO
NOT fill the fuel tank without the mesh filter in place. Clean the filter regularly as described
in 'Maintenance'.
4. When finished refuelling, immediately refit the Fuel Cap and close by turning it clockwise
WARNING: Never use this generator without the Fuel Cap (6) in place and securely closed.
Grounding the generator
WARNING: This generator produces sufficient electrical power to electrocute or seriously
injure a person, if misused.

Pre-operational checks
•
Note: Ensure the device is set up on even ground in a well-ventilated, safe location, where it
does not interfere with your work, other machines or where it could become a threat to other
people.
WARNING: ONLY set up this generator on solid ground. NEVER place the generator on
top of a work platform, scaffolding or other elevated contraptions. Vibration may cause the
generator to move and fall off, and fasteners of scaffoldings may vibrate loose. Metal parts of
scaffoldings could become live if the device malfunctions.
WARNING: This generator MUST NOT be set up where it can pose a risk to anybody in its
vicinity. It MUST NOT be set up where children or pets can gain access to it, or where the
sound and vibration emitted is unacceptable. NEVER set up the generator in wet, damp or
dusty locations, where it can be rained on, or where exhaust fumes may accumulate.
•
1. Open the Fuel Cap (6) and determine if the Fuel Tank (2) holds sufficient fuel
2. Refill if needed, as described in 'Filling with fuel'

until a 'clicking' sound is heard
Connect the Ground Connector (1), located on the side of the generator, with an external
ground system (i.e. an earthing rod or other suitable electrical earth connection)
The ground wire must be a copper wire with the same or a larger cross section than the
supply cord of the attached appliance
The ground wire must have an eyelet terminal with 6mm
internal diameter, to connect to the generator (see Fig.
below for correct electrical connection)
Always use a residual current device (RCD) with a
maximum tripping current of 30mA and a response
time of less than 40ms. Follow the RCD manufacturer's
instructions with regards to installation and operation in
combination with a generator
If extension cords are used to connect earthed devices to
the generator, earthed extension cords of sufficient cross section must be used
