Description of function

4.2.1

The engine, which is flanged to the crankcase and is held in place by

3 screws. drives the percussion system over a gear transmission and

a connecting rod. The engine torque is transmitted by means of a

centrifugal clutch.

4.2.2

The centrifugal clutch interrupts the flow of power to the percussion

system at low engine speeds, thus allowing for a perfect idling of the

engine.

4.2.3

The engine can be switched off with the stop button or the fuel tap.

4.2.4

The drive engine works according to the 2-stroke principle, and is

started mechanically by means of a recoilstarter. The engine is air

cooled and the air necessary for combustion is directed through the air

filter.
