GENERAL
The DYNAPAC BG39 is designed for rough and fine trowelling of concrete floors.
The original manual is in English.
DESIGN
BG39 is driven by a four stroke petrol engine (1) Honda .
They are equipped with a safety switch which shuts down the engine if the operator looses control of the
operating handle (3).
The engine power is transmitted to the rotor supporting the blades (4) through a centrifugal clutch and a
reduction gear box (5). The blades are protected by a guard ring (6).
The blade control knob (7) provides an accurate and easy adjustment of the blade pitch.
The rotation speed of the blades should be adjusted by the throttle lever (8).
The BG39 could be supported on the job site thanks to an optional lifting eye.
