This scroll saw is designed to cut wood, wood compo- sition products, plastic, and nonferrous metals (alumi- num, brass, copper).

GENERAL OPERATION

Please read and understand the following items

concerning your scroll saw before attempting to use the saw.

There is a learning curve for each person who wants to use this saw. During that period of time it is expected that some blades will break until you learn how to use and adjust the saw.

Allow the saw to cut material by guiding the workpiece into the blade as it moves. Do not force the work.

The blade teeth cut material only on the down stroke.

You must guide the workpiece into the blade slowly because the teeth of the blade are very

small and can only remove material on the down stroke.

Scroll saw blades wear out and must be replaced frequently for best cutting results. Scroll saw blades generally stay sharp for 1/2 hour to 2 hours of cutting, depending on type of material and speed of operation.

To get accurate cuts, be prepared to compen- sate for the blade'stendency to follow the wood grain as you are cutting wood.

In cutting wood, best results are achieved when cutting wood less than one inch thick.

When cutting wood thicker than one inch, the

user must guide the workpiece very slowly into the blade and take extra care not to bend or twist

the blade while cutting.

When choosing a blade to use with your scroll saw, consider the following carefully:

Very fine, narrow blades should be used to scroll cut in thin material 1/4 in. thick or less.

Most blade packages state the size or thick- ness and type of material which that blade is intended to cut. Package should also state the radius, o_ size of curve, which can be cut with that blade.

Wider blades cannot cut curves as tight or small as thinner blades.

Blades wear faster:

When cutting plywood and other laminates.

When cutting material thicker than 3/4 in.

When cutting hardwood.

When side pressure is applied to the blade.

ON/OFF KNOB WITH VARIABLE SPEED

See Figure 16.

Your scroll saw has an easy access On/Off knob with variable speed.

Pull the knob out to turn ON the saw, and push the knob in to turn OFF the saw.

Note: After saw is turned on, a hesitation before blade movement is normal.

_IL WARNING: Never leave the saw unattended until the blade has come to a complete stop to

prevent serious personal injury.

ON/OFFKNOB

Fig. 16

By turning the knob, the variable speed control may be adjusted from the high speed of approxi- mately 1600 SPM (Strokes Per Minute) to the low speed of approximately 500 SPM Suggested speeds are identified under Choice of Blade and Speed, page 18. Turn the On/Off knob to the

right or clockwise to increase strokes per minute and to the left or counterclockwise to reduce the

strokes per minute.

This motor has an electronic control that regulates the speed and provides overload protection to the motor. If the motor fails to start after about 2 seconds, push the knob OFF and disconnect the saw from the power source. Refer to the troubleshooting chart.

Note: If the internal overload protector has been tripped, pushing the On/Off knob OFF will reset it.
