MAINTENANCE
Cleaning the Chemical Tank and Pipes
Fill the chemical tank with 25% of clean water and turn on the unit. This will prevent corrosion and the accumulation
of chemical deposits in the tank and pipes.
Spark Plug Maintenance
Remove the spark plug using a spanner or spark plug remover. Remove any carbon deposits between the electrode
and the earth section with a wire brush. Make sure that there is a space of 3 to 5 mm between the electrode and the
earth.
Fuel injector Maintenance
Unscrew the fuel injector situated on the side of the carburettor. Clean the injector with compressed air to remove
any blockages.
