1. The exhaust gas is poisonous, never use a generator indoors or in an attached garage. Always run your
generator outdoors in a well-ventilated area. Keep the generator at least 1 meter (3 feet) away from buildings and
other equipment during operation.
2. Place generator on level ground to operate.
3. The load must be kept within rating stated on generator rating plate, overloading will damage the unit or shorten
its life.
4. Running the engine at excessive speeds is dangerous and will damage the engine.
5. Do not tamper with parts, which may increase or decrease the governed speed.
6. When using extension cords, please make sure they are grounded with sufcient wire gauge for the application.
Heavy-duty outdoor rated cords will handle household appliance loads.
7. The exhaust system gets hot enough to ignite some materials. Do not operate the engine near combustible
materials.
8. Do not store fuel indoors or try to refuel a generator while it is still running. Clean up any spilled fuel before
restarting the engine.
9. The mufer becomes very hot during operation and remains hot for a while after stopping the engine. Be careful
not to touch the mufer while it is hot. Let the engine cool before storing the generator indoors.
10. Turn off all equipment powered by the generator before shutting down your generator.
11. To prevent electric shock or re, never use the machine in rain or snow or connect the generator to a live circuit.
12. Do not connect the generator to another power supply outlet.
13. Protection against electrical shock depends on circuit breakers specically matched to the generating set. If the
circuit breakers require replacement they must be replaced with a circuit breaker having identical ratings and
performance characteristics.
14. Ensure the generator does not have any damaged hoses, loose or missing clamps, damaged tank or cap before
use. All defects should be corrected before use.
15. To prevent surging that may possibly damage equipment, do not allow the engine to run out of fuel when
electrical loads are applied.
16. Before transporting the generator ensure that all the fuel is drained to prevent leakage.
17. Unit must meet operating speed before electrical loads are connected. Always disconnect any loads before
turning off the generator.
18. Keep children and pets away from the generator at all times.
19. The installation and major repair of the generator should only be carried out by trained and fully qualied
engineers.
20. Ensure appropriate ear protection is worn when working in close proximity to the generator.
21. When using extension cables or mobile electric net use the following guidelines:
3. Safety Information
Cable Diameter Maximum Length
1.5 60m
2.5 100m
WARNING:
• Do not cover the unit when in use.
• The unit should be earthed using 4mm diameter grounding wire.
• Do not use the generator in wet or damp conditions.
• Store the generator in well-ventilated area with an empty fuel tank.

4. Checking the Generator Prior to Use
•Check the fuel level and top up with unleaded petrol if necessary. Do not overll the fuel tank (there should be no
fuel in the ller neck).
• After refuelling make sure the tank cap is closed properly and securely. Be careful not to spill fuel when refuelling
and clean up any spilled or excess fuel. Spilled fuel or fuel vapour can ignite when the engine
is started.
• The generator has a maximum fuel capacity of 11 Litres
• Do not fill above the fuel filter top.
• Check the engine oil level and top up if necessary as shown in Fig.1.
Fig.1
5. Starting the Generator
WARNING:
• Make sure there is no air in the fuel pipe when using the unit for the rst time, starting the
unit or refuelling an empty tank. You can drain away air by loosening the connection
between the injection pump and pipeline then drain the air until the fuel comes out.
• Do not loosen or adjust either the engine speed limit bolt or fuel injection limit bolt. These
have been set to their optimum settings before leaving the factory.
• Never pull out the start handle when diesel engine is running. This is dangerous and can
damage the engine.
1. Warm up the engine without the load for about 3 minutes.
2. Open the Fuel Cock.
3. Put the starting switch into the "Run" position.
4. Hold the starting/recoil handle loosely and pull the cord out it until
you feel resistance - then return it slowly.
6. Hold the starting/recoil handle rmly - then pull the cord hard and
fast as far as it will go. Use two hands if necessary. Repeat the
process until the engine starts.
Note: To make it easier to start the generator in cold temperatures
remove the oil plug and add 2cc of engine oil before starting.

7. Stopping the Generator
1. Before stopping the generator, allow it to run for approximately 3 minutes with no consumers so that it can "cool
down".
2. Turn off the circuit breaker.
3. Turn the key/ignition switch to the "OFF" position.
4. Turn the fuel cock lever to the "CLOSED" position.
8. Transportation and Storage
• When transporting the generator, ensure the starting switch is set to the "OFF" position and that the fuel valve is
set to the "Closed" position.
• Keep the generator level to prevent fuel spillage. Fuel vapour or spilled fuel may ignite. Touching a hot engine can
cause serious burns or res.
• Let the engine cool before transporting or storing the generator.
• Make sure not to drop or strike the generator when transporting. Do not place heavy objects on top of the
generator during transit, storage or operation.
6. Connecting Consumers to the Generator
1. Connect the machine you want to use to the AC socket. Note: Do not exceed the specied load limit of the
specied maximum AC output.
2. Do not connect the generator to the household network as this may result in damage to the generator itself or to
other electrical appliances in your home.
9. Operation Environment
• This unit can generate rated output under the following conditions:
• The Generator should work in low output under the following conditions:
Altitude Ambient Temperature Relative Humidty
0m +20º 60%
Altitude Ambient Temperature Relative Humidty
>1000m >40º90%

Notes:
• Checking and the engine oil: With generator on level ground: remove the oil ller cap and dipstick clean with a
clean cloth. Insert the dipstick back into the oil lter hole without turning - remove and check that the oil level is
between the minimum and maximum indicators. If level is low rell to the maximum level mark.
●Checking the fuel level: With generator on level ground: open the fuel tank cap. Check the fuel level. If level is low
refuel up to the red marker on the fuel lter. Put the fuel cap back on.
WARNING:
• Ensure that any electrical equipment is disconnected from the generator before carrying
out any maintenance work on the generator.
• The circuit breaker should be in the "OFF" position before maintenance.
• The unit should be eatherd at all times.

11. Technical Specification
Noise Level Information
The figures quoted in this table are
emission (sound power) levels and are not
necessarily safe working levels.
Whilst there is a correlation between
the emission and exposure levels, this can
not be used reliably to determine whether
or not further precautions are required.
Factors that influence the actual level of
exposure to the work-force include the
characteristics of the work room, the
other sources of noise, the number of
machines and other adjacent processes,
and the length of time for which an
operator is exposed to the noise. Also
the permissible exposure level can vary
between regions.
This information, however, will allow the
user of the machine to make a better
evaluation of the hazard and risk.
