VARIABLE SPEED CONTROL

Your jointer is supplied with a variable speed control knob (A) Fig. 23, that enables you to operate the machine at cutterhead speeds between 6000 and 11,000 RPM. Speed indicators of 1-2-3-4 and 5 are provided on the speed dial as shown. When the pointer (B) is pointing to 1, the cutterhead speed will be 6000 RPM; 2 – 7250 RPM; 3 – 8800 RPM; 4 – 9750 RPM; and 5 – 11,000 RPM.
