This is the Portuguese-language operating instructions booklet for the Buffalo BFGE 23.0 engine, a gasoline, air-cooled, 2-cylinder V, 4-stroke OHV engine with 679 cm³ displacement and 23.0 cv maximum power. It covers safety procedures, fire and carbon-monoxide precautions, handling and lifting, battery connection and care, the engine's main components, technical characteristics and a torque table.
The manual then explains oil filling (SAE 20W50, 1.200 ml), starting and stopping procedures, and includes an electrical diagram plus a customer/reseller delivery questionnaire. The engine is shipped without oil in the crankcase, requires a minimum 12V 21Ah battery, and is intended for applications such as motor pumps, generators, garden equipment and small harvesters. This manual is written in Portuguese.

Use SAE 20W50 lubricating oil in specification API SF-SG-SH-SJ, filled with 1.200 ml through the oil plug on top of the left cylinder head.
No. The engine is shipped from the factory without oil in the crankcase, so it must be filled with the recommended oil before starting.
On the first start, let the engine run about 15 minutes without load before applying load; on later starts this time should be 3 to 5 minutes.
Because the carburetor has a solenoid valve that releases fuel only when the battery is connected and the start switch is in the ON position.
