Instruction manual

Basic 90° straight or curved cuts

All cuts made with the blade at 90° to the table follow the same basic principals. Start by marking or transferring

your pattern or reference lines onto you workpiece.

Note: The EX-21 has a 21” throat that allow for a workpiece of up to 21” of clearance to swing completely around without

hitting the back of the saw. If necessary, rough-cut the workpiece down to a workable size before starting intricate work on

the scroll saw.

Blade speed selection is subjective and is dependant on a variety of factors: type and thickness of material being

cut, type of blade being used, feed rate, required finish quality as well as experience, personal preference and com-

fort level of the user. There are no hard and fast rules. Be patient – practice and experience will be your best teacher.

Here are some general guidelines to consider when selecting/adjusting blade speed:

• For best results and smoothest most efficient cutting, always select the highest blade speed that you are comfort

able using based on your experience and skill level.

• Generally speaking, harder or denser workpiece material requires slower blade speeds.

• 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.

Adjusting the Blower

The EX-21 is equipped with a built-in blower to help clear cutting

dust from the workpiece surface in front of the blade and on any

reference lines. Adjust the blower tube as needed to point the

nozzle at the blade to set it at a comfortable distance so as not to

obstruct your hand movement as you work. (See Fig. 6)

Workpiece Hold-Down

The workpiece hold-down (See Fig. 6) can be adjusted to assist

in preventing the blade from lifting the workpiece up from the

table during the cut. Loosen the thumbscrew to set the height

to your convenience based on the thickness of the workpiece.

Before cutting, test to make sure that the hold-down is not adjust-

ed too tightly to the workpiece or that it obstructs the movement

of the workpiece.
