A dirty or blocked coolingsystem results in the machine overheating which causesdamage to the piston and cylinder.Note! The cooling system on a chain saw with catalyticconverter must be cleaned daily. This is particularlyimportant on chain saws with catalytic converters,because the higher exhaust temperature requiresefficient cooling of the engine and the catalytic converterunit.”Air Injection” centrifugalcleaningCentrifugal cleaning means the following: All air to thecarburetor passes through the starter.
