ONCEPT AND MAIN APPLICATIONS
Model RBC413U is symmetric design bike handle style Petrol brushcutter
powered by 40.2 mL 2-stroke engine.
This product has been developed based on RBC411U, and Diaphragm
carburetor has been employed instead of the float type carburetor of RBC411U.
Other basic features are the same as RBC411U; therefore, the engine for
this model does not comply with well-known exhaust emission regulations.
RBC414U is asymmetric design bike handle style. The handle can be removed
quickly from drive shaft without tool. The others are the same as RBC413U.
RBC414UG is only available in Brazil for use of E25 gasoline (mixture of 25%
anhydrous ethanol and 75% gasoline.)
