The oil
fl ow rate can be adjusted with
adjusting screw A :
• Turn right for more oil
• Turn left for less oil

forth and work it off the shaft.

The suction line 5 remains in the crankcase.
It extends into the oil tank. To remove it,
carefully pull on the connection to the oil
pump.
Removing the oil pump
Push the adjusting screw A up against the
spring pressure and turn it until the pin 6 goes
into the assembly slit 6 . If necessary press the
supply piston 7 in somewhat.

The ventilation valve 8 must be
