Prepration For Use
All extension cables from the generator set to the appliance must be carefully selected, fitted, and maintained. Cables by IEC 245-4 should be used.
Cables should be inspected regularly and should be replaced, not repaired, in the event of a defect.
The length and cross-section of conductors should be selected according to the job to be done. The table below is an indication of the sizes that should be used.

Ensure the cable is fully unwound when in use to avoid overheating and the placing of extra load on the generator.
Operation
Start the engine as follows (referring to the engine manual) and allow it to run for a few minutes at full speed for it to warm up.
- Move the fuel valve lever to the ON position
- To start a cold engine, move the choke lever to the closed position.
- Pull the recoil starter grip lightly until you feel resistance, then pull briskly. Return the starter grip gently.

- To restart a warm engine, leave the choke lever in the Clarke CP5050N 5.0kVA Petrol Generator open position.
- Set the engine speed by moving the throttle lever away from the MI position.n

- Check the condition of the appliance, including the supply cable and the extension cable if used, and ensure it is switched OFF. Ensure also that the operating voltage is the same as the output from the generator.
- For generators with dual output, ensure the voltage selector switch is set to deliver the appropriate output – 115V or 230V,

- With the engine running smoothly, connect the appliance Clarke CP5050N 5.0kVA Petrol Generator to the appropriate receptacle: BLUE – 230V, YELLOW – 115V.
Be Aware
Some appliances draw more current on start-up than their normal running current, i.e., electric motor and compressors.
