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.
Note: Recommended Min Load is 50% to prevent carbon build-up on the engine.
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. Unit must meet operating speed before electrical loads are connected.
11. Turn off all equipment powered by the generator before shutting down your generator.
12. To prevent electric shock or re, never use the machine in rain or snow or connect the generator to a live circuit.
13. Do not connect the generator to another power supply outlet.
14. 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.
15. 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.
16. To prevent surging that may possibly damage equipment, do not allow the engine to run out of fuel when
electrical loads are applied.
17. Before transporting the generator ensure that all the fuel is drained to prevent leakage.
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.
2. Safety Information
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.

3. Checking Generator Prior to Use 5. Connecting Consumers to the Generator
•Check the fuel level and top up with diesel fuel 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.
• 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
4. Starting the Generator
1. Warm up the engine without the load for about 3 minutes.
2. Open the Fuel Cock.
Recoil Start
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.
5. Push the decompression lever down and then release it.
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.
Electric Start
1. Turn the ignition key to the "Start" position.
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. 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.
6. 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.
7. Transporting 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 "CLOSED3" 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.
Note: To make it easier to start the generator in cold temperatures
remove the oil plug and add 2cc of engine oil before starting.
