Changing Blades
A typical scroll saw blade will wear out in 1⁄2 to 2 hours, depending on the material cut. Blades become dull quicker when cutting thick material, plywood, laminates, hardwoods and metal.
To change the blade:
1.Disconnect the machine from the power source.
2.Loosen the blade tension adjustment knob.
3.Remove the throat plate and move the blade guards up.
4.Push down on the upper arm shown in Figure 10, pull the upper end of blade out of the holder, push down on the blade to free the lower end of the blade, and pull the blade up to remove.

5.Feed the new blade through the table and hook it into the lower blade holder as shown in Figure 11. The teeth should face forward and down.

6.Push down on the upper blade holder and slide the upper end of the blade into the hold- er. Make sure that the pins are seated into the grooves in both holders.
7.Increase the tension on the blade until the blade gives a musical sound when plucked.
8.Replace the throat plate and lower the blade guards into position.
