PDM-30 speed chart

[Mathurin]

In the 12 speeds chart, the belt position 1-8 it suppose to be 2500 RPM but it is 120 RPM the lowest speed because you transfert a small pulley to bigger pulley 2 times is it an error on the chart

I couldn't find a PDM-30 manual online, but looking the Grizzly Manual for their version, it looks like Grizzly diagram is correct.

Largest Motor Pulley drives Smallest Idler Pulley "#8" (for speed increase), 1 to 1 idler, Larger Idler Pulley drives Smallest Spindle Pulley "#1
" (for further "Maximum" speed increase)

Hope this helps.

Sorry, I just realize , in front of my mill, the motor pulleys arent on my right an on the diagram, the motor pulleys arent on my left. All the difference
