Operating Instructions

During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This helps protect engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
engine to cool down. Keep the machine
in a dry place, well away from sources of
ignition, until you need it again. For
longer out-of-service periods – see

"Storing the Machine".
