Page 5
5. Never start the engine if there is spilled fuel. Any spillage must be wiped clean and the generator allowed to dry before attempting to start the engine.

PREVENTION OF ELECTRIC SHOCK

1. Never use the generator in wet conditions unless it is well protected/ under cover. Under these conditions, adequate ventilation MUST be provided
2. Never operate the generator with wet hands
3. Never use water or any other liquids to clean the generator.
4. Make sure you ground (earth) the generator.

ADDITIONAL SAFETY RULES FOR GENERATORS

2.
Always
carrying out any maintenance.
3. Always ensure the generator reaches operating speed before connecting a load.
4. Never allow the generator to run out of fuel when a load is connected.
5. Never transport the generator with fuel in the tank.

UNPACKING AND ASSEMBLY

Unpack your generator and make sure the following items are present.
1 x Generator 1 x Battery Charging Lead Assembly
1 x Spark Plug Box Spanner 1 x Fuel Mixing Cup (inside fuel tank cap)
1 x Tommy Bar 1 x Instruction Manual
Should there be anything missing or damaged in transit contact your Clarke dealer immediately.

BEFORE USING THE GENERATOR

IMPORTANT: Generators should ALWAYS be earthed. Make sure you ground (earth) the generator.
Before using your generator check that:
• The generator is in good condition and free from any damage.
• The generator is clean and free from fuel or oil spillage.
• The generator is correctly positioned for use (See page 4).
• The fuel system and connectors are intact and there is no leakage.
NOTE: Always use a funnel to fill the fuel tank so as to avoid accidental
spillage of fuel. If fuel is spilled it must be cleaned up before attempting to start the engine.
WARNING: ENSURE THERE IS ADEQUATE FUEL IN THE TANK WHEN USING THE GENERATOR. RUNNING OUT OF FUEL OR STOPPING THE ENGINE SUDDENLY WITH A LOAD CONNECTED COULD CAUSE SERIOUS DAMAGE.

EARTH CONNECTOR

Always connect the generator to an earth point. The earth terminal is shown on the right.

ADDING THE FUEL/OIL MIXTURE

WARNING: FUEL IS HIGHLY FLAMMABLE AND POISONOUS.
WARNING: WIPE UP ANY SPILLED FUEL IMMEDIATELY.
WARNING: AFTER REFUELING, MAKE SURE THE FUEL CAP IS TIGHTENED SECURELY.
The generator requires a 50:1 mixture of fuel and oil. To mix the fuel you will need a 5L container with a screw-on lid suitable for storing petrol.
1. Pour the required amount of petrol into the container.
• Your generator has been designed to use regular unleaded petrol
with an octane rating of 86 or higher.
2. Remove the fuel cap from the generator.
3. Use the measuring cup attached to the fuel cap to measure the required amount of oil.
• Add 0.02L of oil to every litre of
fuel.
IMPORTANT: Only use approved two stroke engine oil, standard engine oil is not suitable.
Amount of Fuel Add this much Oil
1L 0.02L
2L 0.04L
3L 0.06L
4L 0.08L
Replace the lid on the container holding the petrol/oil mixture and shake the container to mix the contents.
4. Slowly pour the mixture into the fuel tank (maximum 4.2L)
• Do not overfill the fuel tank.
5. Replace the fuel cap securely.
NOTE: The measuring cup MUST be fitted onto the fuel cap when the cap
is replaced, it forms an important part of the fuel system and may cause damage to the generator if it is not fitted.

USING YOUR GENERATOR

Make sure there is sufficient fuel in the tank before using the generator.

STARTING THE ENGINE

1. Remove all connections from the AC sockets.
2. Turn fuel valve to the ON position.
3. Set the choke lever to the “I” position (all the way to the left).
4. Set the engine switch to the “I” (ON) position.
5. Hold the generator handle firmly and pull the starting handle lightly until you start to feel resistance and then pull up sharply to start the engine.
NOTE: You may have to do this
more than once.
WARNING: ONCE THE GENERATOR HAS STARTED, RELEASE THE STARTING HANDLE SLOWLY TO AVOID INJURY/DAMAGE AS IT WHIPS BACK.
10
Page 11
6. Once the engine has warmed up, return the choke lever to the run position (all the way to the right).

SHUTTING DOWN THE GENERATOR

To stop the generator in an emergency simply set the engine switch to ‘0’ (OFF) position.
1. Turn off and disconnect any electric devices.
2. Set the engine switch to the “0” (OFF) position.
3. Turn the fuel valve to the “OFF” position.
