Take care that the oil inlet pipe (« T » fig. 28) from oil tank to the device (« LS » .) is
completely full; if air bubbles are present, take off the pipe « 0 » from the device « LS »,
flow down same oil so that the above bubbles are eliminated, then reconnect the pipe.
Don't fill up the tank for petrol (gasoline) with petrol- oil mixture but with pure petrol (gas)

system; the oil is conveyed in the suction pipe by means of a ,« LS » device (« M », fig.
28) composed of a piston pump with variable stroke, controlled by the crankshaft through
a gear transmission. The oil tank is provided with a transparent cup (« S », fig. 29)
