ELECTRICAL REQUIREMENTS AND SAFETY
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides
a path of least resistance for electric currents and reduces the risk of electric shock. This tool is equipped with an electrical cord that has an equipment­grounding conductor and a grounding plug. The plug must be plugged into a matching receptacle that is properly installed and grounded in accordance with all local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the
receptacle, have the proper receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in risk of electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electrical cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service person if you do not completely understand the grounding instructions, or if you are not certain the tool is properly grounded.
USE only three-wire extension cords that have three-pronged grounding plugs with three-pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cords immediately.
GUIDELINES FOR EXTENSION CORDS
USE THE PROPER EXTENSION CORD. Make sure your extension cord
is in good condition. Use an extension cord heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power, overheating and burning out of the motor. The table on the right shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified technician before using it. Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tool. This circuit must not be less than #18 wire with a 1.6 A time-lag fuse. NOTE: When using an extension cord on a circuit with a #18 wire, the extension cord must not exceed 25 feet in length. Before connecting the motor to the power line, make sure the switch is in the off position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage
10 11
the motor. This tool is intended for use on a circuit that has a receptacle like the one illustrated in Fig. 1.
Fig. 1
Three-Pronged Plug
Fig. 1 shows a three-pronged electrical plug and receptacle that has a grounding conductor. If a properly grounded receptacle is not available, an adapter (sold separately) (Fig. 2) can be used to temporarily connect this plug to a two-contact grounded receptacle. The adapter (Fig. 2) has a rigid lug extending from it that MUST be connected to a permanent earth ground, such as a properly grounded receptacle box.
CAUTION
● In all cases, make certain the
receptacle is properly grounded. If you are not sure, have a qualified electrician check the receptacle.
● This tool is for indoor use only.
Do not expose to rain or use in damp locations.
● This tool must be grounded while
in use to protect the operator from electric shock.
● Never remove the grounding
prong from the power cord. If damaged, discontinue use of unit and contact customer service for a replacement cord.

BLADE SELECTION (FIG. T)
WARNING
!
To avoid injury from accidental starting, always turn the switch OFF and unplug the scroll saw before moving, replacing the blade or making adjustments.
This scroll saw accepts 5-inch length blades with a wide variety of blade thickness and widths. The type of material and intricacies of cutting operations (size of radius or curve) will determine the number of teeth per inch. As a general rule, always select the narrowest blades for intricate curve cutting and the widest blades for straight and large curve cutting operations.
Use this table as an example, but practice and your own personal preference will be the best selection method.
NOTE: When using blades, sometimes speeds must change to compensate for smaller curves, radii or smaller diameters. Thinner blades will have more possibilities for blade deflection when cutting angles which are not perpendicular to the table. Read BASIC SCROLL SAW OPERATION for more suggestions.
NOTE: The blade must be installed with the teeth pointing downward, as shown in Fig. T, to prevent the workpiece from being pulled upward by the saw blade action.

OPERATION
VARIABLE SPEED CONTROL AND ON/OFF SWITCH
WARNING
!
For your own safety, always push
the switch “OFF” when the scroll saw is not in use. Also, in the case of power failure (all of your lights go out) push the knob “OFF”. Remove the plug from the power source outlet to avoid accidental starting.
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.
VARIABLE SPEED SWITCH (FIG. U)
1. Your saw is equipped with a variable speed control knob (1). The blade stroke rate may be adjusted by simply rotating the variable speed control knob (1).
2. Turn the control knob clockwise the increase up to 1,600 strokes per minute (SPM). Turn the control knob counterclockwise to reduce, down to 400 strokes per minute (SPM).
ON/OFF SWITCH (FIG. U)
1. To turn power ON or OFF, push the ON/OFF switch (2).
OVERLOAD BREAKER (FIG. U)
When the motor in overload during operation, the overload breaker will cause the motor to stop automatically to prevent damage to the motor. Push in the ON/OFF switch (2) to turn saw OFF, after that push the ON/OFF switch (2) to ON to start the saw. Other way to restart the saw: Disconnect the power supply firstly, keep switch in ON position, then connect the power supply, the motor will start automatically.

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
26 27
1
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, depending on material being cut.
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. Plastics and non-ferrous metals 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.
11. This saw uses 5 in. long pin or plain end type blades only.
12. Blades wear faster when cutting plywood or particle board which is very abrasive. Angle cutting in hardwoods reduces blade tooth set faster due to the blade deflection.
FREEHAND CUTTING (FIG. V)
WARNING
!

MAINTENANCE
WARNING
!
For your own safety, turn the switch OFF and remove the plug from the power source before maintaining your saw.
GENERAL
An occasional coat of paste wax on the work table will allow the wood being cut to glide smoothly across the work surface.
MOTOR
1. If the power cord is worn, cut or damaged in any way, have it replaced immediately by authorized electrician.
2. Do not attempt to oil the motor bearings or service the motor internal parts.
REPLACING CARBON BRUSHES (FIG. Z)
Replace both carbon brushes when either has less than 1/4 in. length of carbon remaining, or if the spring or wire is damaged or burned. To inspect or replace brushes, first unplug the saw. Then remove the black plastic cap (1) on the side of the motor (2). Carefully remove the spring-loaded cap. Then pull out the brush and replace. Replace for the other side. To reassemble reverse the procedure. The ears on the metal end of the assembly go in the same hole the carbon part fits
into. Tighten the cap snugly, but do not overtighten. NOTE: When reinstalling the same brushes, put them back in the way they came out. This will avoid a break-in period that reduces motor performance and increases wear.
