G0537 Scroll Saw -15-
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.
Note—Determining correct blade tension is
subjective and is learned through experi-
ence. If the blade is not tensioned enough
the blade will drift off the layout line when
cutting. The scroll saw will also have exces-
sive noise and vibration. If the blade is too
tight the blade could break, causing serious
injury. Blades that are tensioned correctly
will last longer and are less likely to break.
8. Replace the throat plate and lower the blade
guards into position.
