What speed should my spinner discs be turning at?
Your spinner discs should be turning at 850RPM (at 50 litres per minute). This can be easily measured with a tachometer. These are available from our parts department if you need one. Or any local mechanic.
When standing at the back of the machine, the right-hand spinner disc should turn clockwise and the left-hand spinner disc anti-clockwise.
Please note, if you have older OMP32cc motors instead of the new OMP50cc then your spinner discs should be turning at 850RPM (but at 35 litres per minute).
