9. Storage
• Oil the blades.
• Aged fuel is one of major causes of engine
starting failure. Before storing the unit, empty the
fuel tank and run the engine until it uses all the
fuel left in the fuel line and the carburetor. Store
the unit indoor taking necessary measures for
rust prevention.
8. Maintenance
around the cylinder cooling fins after every 25
hours of use for blockage, and remove any
waste which has attached itself to the
reciprocator. Note that it is necessary to remove
the engine cover shown in (MA11) in order to be
able to view the upper part of the cylinder.
• If waste gets stuck and causes blockage around
the intake air cooling vent or between the
cylinder fins, it may cause the engine to
overheat, and that in turn may cause mechanical
failure on the part of the reciprocator. (MA11)
