OPERATION

REPLACING THE BULB (FIG. S)

1.Use only a 10 watt maximum bulb. Turn the light switch (1) OFF (O) and unplug the saw.

2.Remove old bulb. Place new bulb into socket.

WARNING

●To prevent injury resulted from heat of the light bulb. Never touch the light bulb.

●To prevent electric shock. Never touch the bulb socket when the plug from the power source is connected.

ON (I) / OFF (O) SWITCH (FIG. S)

1.To turn power ON (I) or OFF (O), push the ON (I) / OFF (O) switch (2).

VARIABLE SPEED CONTROL KNOB (FIG. S)

The variable speed control allows greater versatility to cut a variety of materials such as wood, plastics, non-ferrous metals, etc. Depending on the hardness and thickness of material, the speed should be reduced to allow the blade teeth to remove cut material from the kerf.

1.Your saw is equipped with a variable speed control knob (3). The blade stroke rate may be adjusted by simply rotating the variable speed control knob (1). To increase speed, rotate dial clockwise. To reduce speed, rotate dial counterclockwise.

RECOMMENDATIONS FOR CUTTING

1.When feeding the workpiece into the blade do not force the leading edge of the workpiece into the blade because the blade will deflect, reducing the accuracy of cut and possibly breaking the blade. Allow the saw to cut material by guiding the workpiece into the blade as it cuts.

2.The blade teeth cut material ONLY on the down stroke.

3.You must guide the wood into the blade slowly because the teeth of the blade are very small and they can only remove wood when they are on the down stroke.

4.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 the saw and receive the greatest benefit from the blades.

5.Best results are achieved when cutting wood less than one inch thick.

6.When cutting wood thicker than one inch, the user must guide the wood very slowly into the blade and take extra care not to bend or twist the blade while cutting in order to maximize blade life.

7.Teeth on scroll saw blades wear out and must be replaced frequently for best cutting results. Scroll saw blades generally stay sharp for 1/2 to 2 hours of cutting.

8.To get accurate cuts, be prepared to compensate for the blade’s tendency to follow the wood grain as you are cutting.

9.This scroll saw is intended to cut wood or wood products. Precious and non-ferrous perform well on scroll saws that have very slow speed capability, and should be lubricated with machine oil or beeswax.

10.When choosing a blade to use with your scroll saw, consider very fine, narrow blades to scroll cut in thin wood 1/4 in. thick or less. Use wider blades for thicker materials but this will reduce the ability to cut tight curves.
