• Slower speeds also work better with very thin blades, or when cutting most metals as well as for

brittle or delicate material such as fine veneers.

• Some wood species will have a tendency to burn quicker at higher blade speeds. To avoid

additional sanding later, reduce blade speed and feed speed at the first signs of burn marks on

the workpiece.

11.2.5. Making the Cuts

a. Turn on the saw and set the speed controller to the desired blade speed.

b. With your fingers holding the piece firm to the table, and using

your thumbs for directional control, (see Figure 6 & 7) feed the

workpiece into the blade using steady, even pressure.

c. Make sure that the blade is cutting on the waste side of your

reference line and adjust feed direction slightly as needed to

compensate for blade drift.

d. As you begin cutting, keep firm but not-white knuckled

pressure on the wood. If you don’t keep firm pressure on it,

the blade will get a hold and rapidly move it up and down

against the table’s surface. This is called “chatter.” Besides

scaring you the first time it happens, you can damage the piece

you’re cutting.

e. You’ll probably notice when you start to cut that you can’t

seem to saw in a straight line. Due to the manufacturing process, there’s a slight burr on one

side of the blade. To compensate, take a scrap piece of wood and cut into it to see the direction

the blade is cutting. Shift your body position relative to this line so as you push the blade into

the wood, you’ll be cutting straight again. (If the drift is large, you may not have enough tension

on the blade.)

f. To stay in control on tight curve cuts, slow down your feed rate as needed to allow the blade

teeth time to make the cut. Avoid coming to a complete stop whenever possible as this can

leave burn marks on the workpiece and also makes it more difficult to get the piece re-started

and moving through the cut again. Avoid forcing through a curve cut as this can cause the blade

to twist and cut off-track or may even cause the blade to break.
