Before you begin any table saw 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 saw come up to speed. Caution: Never turn the speed dial when the Mark V is stopped. You could damage the speed changing mechanism. Always turn the speed to “Slow” before turning off the machine.
The correct speed is determined by the operation you're about to perform and the type of material you're sawing. Generally, you can use faster speeds in softer woods. Faster speeds will also give you a smoother cut. Slower speeds give the machine more torque to get through hard, dense woods.
To determine the right speed for the job, refer to Table 2-1. A good rule of thumb is: The deeper the cut or the harder the wood, the slower the speed. But if the blade turns too slowly, you may get a rough, splintery cut.
