• Check the spark plug
Remove the spark plug using a spanner or spark plug remover. Hold the plug by its plastic cap and press the start
button to check if there is a spark between the electrode and the earth. Also you should hear if there buzzing sound
from the ignition coil.
If there is no spark:
Clean any carbon deposits in between the electrode and earth with a wire brush.
Check that there is a distance of 3 to 5 mm between the electrode and earth.
Check that the battery is fully charged.
Check that the battery and ignition coil are working. If necessary, replace the battery or coil
Clean the contacts and wires inside the battery case
Once these checks have been carried out, try starting the machine again.
• Check the fuel is being injected into the carburettor.
Examine the fuel hose located on the side of the fuel tank to make sure it’s not blocked. Make sure the fuel tank is
full before starting the machine. Make sure the seal in the petrol cap is not damaged. Make sure the cap is firmly
closed to prevent leakage. Unscrew the fuel injector from the side of the carburettor but keep it attached to the
metal fuel pipe. Pointing the injector away from the machine and any people, press the start button and on each
stroke of the compressor pump, fuel should be injected. If not, examine that the injector is not blocked. Do this by
unscrewing the filter from the metal pipe and clean the filter with compressed air.
• Check the Petal Valve.
Remove the spark plug cap, filter and unscrew the carburettor. Examine the petal valve to see if it’s damaged. If it’s
damaged, replace petal valve. TIP: It’s important to assemble the parts of the carburettor in the order there where
disassembled. The distance between the petal valve and the valve plate o should be approximately 1 mm.
