Before you begin any mortising operation, set the Mark V to run at the correct speed. To do this: turn the machine on, turn the speed dial to the correct speed and let the machine come up to speed.
The operating speeds for mortising range from speed setting “H” (1600 RPM)to “G” (1450 RPM). For the most part, the correct speed is determined by the size of the mortise you want to make and the material you're using. Generally, you can use faster speeds with softer woods or smaller mortises. Use slower speeds as the materials get harder and the mortises get larger.
