SAFETY INSTRUCTIONS The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols and the explanations with them deserve your careful attention and understanding. The symbol warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are no substitutes for proper accident prevention measures.
SAFETY INSTRUCTIONS Safety is a combination of using common sense, staying alert, and knowing how your scroll saw works. Read this manual to understand this scroll saw and how to use it safely. WARNING: Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. Save all warnings and instructions for future reference.
SAFETY INSTRUCTIONS perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect the tool's operation. A guard or other part that is damaged should be properly repaired or replaced. • DIRECTION OF FEED. Feed work into a knife against the direction of rotation of the knife only. • NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.
SAFETY INSTRUCTIONS equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or service technician if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only three-wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool's plug, as shown in Fig.
SAFETY INSTRUCTIONS • Blade Thickness: The blade thickness is the distance between sides of blade. A thicker blade has more rigidity and stronger teeth. A narrow, thick blade is used to make curves and a wide, thin blade is used to make long, straight cuts. • Blade Pitch: The blade pitch is the number of teeth per inch or tooth size. A blade with more teeth per inch produces a smoother cut. The type of material to be cut determines the number of teeth that should be in contact with the workpiece.

ASSEMBLY UNPACKING YOUR SCROLL SAW Do not use this product if any parts of the package contents are already assembled to your product when you unpack it. Package contents are not assembled to the product by the manufacturer and require customer installation. Use of a product that may have been improperly assembled could result in serious personal injury. • Unpack all parts and lay them on a flat, stable surface. • Remove all packing materials and shipping devices if applicable.
ASSEMBLY MOUNTING SCROLL WORKBENCH (Fig. 2) SAW TO If the scroll saw is to be used in a permanent application, we recommend that you secure it in a permanent location such as a workbench. When mounting the saw to a workbench, holes should be drilled through the supporting surface of the workbench. • Insert one rubber foot (A) into each hole (B) of the base on the scroll saw assembly.
ASSEMBLY DROP FOOT ADJUSTMENT (Fig. 3) FIG. 3 To prevent workpiece from lifting, the drop foot (A) should be rests flat above the workpiece and the drop foot adjusted so it is parallel to the working table when angle cutting. The drop foot should not be adjusted so that the workpiece drags. Always retighten the drop foot lock knob (B) after each adjustment has been made. • To adjust, loosen the screw (C), tilt the drop foot (A) so it is parallel to the working table, and tighten the screw.
ASSEMBLY SQUARING THE WORKING TABLE TO THE BLADE (Fig. 6a-6c) • Open the blade guard (A) upward. • Loosen the screw (B) and remove the drop foot (C). • Loosen the bevel adjustment knob (D) to tilt the work table until it is approximately perpendicular or at right angle to the blade. • Place a right angle ruler (E) on the work table (F) next to the saw blade (G). • Loosen the screw (H) holding the scale indicator (I). Move indicator to the 0° mark and securely tighten screw.
ASSEMBLY BLADE SELECTION (Fig. 7) FIG. 7 This scroll saw accepts 5" (12.7 cm) length pin-end and pinless blades, with a wide variety of blade thicknesses and widths. The type of material and intricacies of cutting operations will determine the number of teeth required per inch. Always select the narrowest blades for intricate (tight radius and curves) curve cutting and the widest blades for straight and large curve cutting operations. The following table represents suggestions for various materials.
ASSEMBLY BLADE REMOVAL AND INSTALLATION (Fig. 8a-8e) FIG. 8a A PIN-END BLADE (Fig. 8a-8c) CAUTION: To prevent personal injury, always turn saw OFF and disconnect the plug from the power source before changing blades. CAUTION: When installing pin-end blades, the slot on the blade holder must be slightly wider than the thickness of the blade. After the blade is installed, the blade tension knob will keep it in place. Pin-end blades are thicker for stability and for faster assembly.
ASSEMBLY PINLESS BLADE (NOT INCLUDED) (Fig. 8a, 8d-8e) FIG. 8d C To remove a blade: • Open the blade guard upward. • Loosen the blade tension by pushing the blade tension knob (A) up. (Fig. 8a) • Turn the bevel adjustment knob (G) clockwise to tilt the work table until it is 45° left. • Loosen the upper blade screw (H) and lower blade clamp screw (I) with 2.5mm hex key supplied.
ASSEMBLY DUST EXTRACTION PORT (Fig. 9) FIG. 9 This scroll saw allows a hose or vacuum accessory (not provided) to be connected to the dust-extraction port (A) at the front of the saw. If excessive sawdust buildup occurs inside the base, use a wet/dry vacuum cleaner or manually remove sawdust. This will keep your saw cutting efficiently.
OPERATION RECOMMENDATIONS FOR CUTTING A scroll saw is basically a curve-cutting machine. It can also be used for straight cutting and beveling or angle cutting operations. Please read and understand the following items before attempting to use the saw. • When feeding the workpiece into the blade, do not force it against the blade. This could cause blade deflection. Allow the saw to cut the material by guiding the workpiece into the blade as it cuts. • The blade teeth cut material ONLY on the down stroke.
OPERATION rock or slip while being cut. REMOVING JAMMED MATERIAL When backing out the workpiece, the blade may bind in the kerf (cut). This is usually caused by sawdust clogging the kerf or when the blade comes out of the blade holders. If this happens: • Wait until the saw has come to a full and complete stop. • Place the switch in the Off position. • Unplug the saw from the power source. • Remove the saw's blade and the workpiece, refer to section on “blade removal and installation.
OPERATION LED LIGHT SWITCH (Fig. 11) FIG. 11 • To turn the light on, press the light switch (A) to the On (I) position. • To turn the light off, press the light switch(A) to the Off (O) position. A FREEHAND CUTTING (Fig. 11) • Lay out desired design, or secure design to the workpiece. • Raise the drop foot (A) by loosening the drop foot lock knob (B). • Position the workpiece against the blade and place the drop foot against the top surface of the workpiece.
OPERATION RIP OR STRAIGHT LINE CUTTING (Fig. 13) FIG. 13 • Raise the drop foot by loosening the drop foot lock knob. • Measure from the tip of the blade to the desired distance. Position the straight edge parallel to the blade at that distance. • Clamp the straight edge to the table. • Recheck your measurements using the workpiece to be cut and make sure the straight edge is secure. • Position the drop foot against the the top surface of the workpiece.
OPERATION BEVEL CUTTING (ANGLE CUTTING) (Fig. 15a-15b) • Lay out or secure design to workpiece. • Move the drop foot to the highest position by loosening the drop foot lock knob. Retighten the drop foot lock knob. • Tilt the table to the desired angle by loosening the bevel adjusting knob (A) to move the work table to the proper angle using the bevel scale (B) and the bevel indicator (C). • Tighten the bevel adjusting knob (A).
MAINTENANCE WARNING: To ensure safety and reliability, all repairs should be performed by a qualified. service technician. WARNING: When servicing, use only identical replacement parts. The use of any other parts may create a hazard or cause damage to the tool. WARNING: Always switch the product off, disconnect it from the power supply and let the product cool down before performing inspection, maintenance, lubrication and cleaning work! CLEANING • Keep your scroll saw clean.
MAINTENANCE • Run the saw for approximately five to ten minutes to allow the brushes to "seat" themselves. If the brushes are not seated correctly, the electric brake may not function correctly and could damage the motor. While the brushes are seating, some sparking may be noticed in the motor. This is normal for new brushes. STORAGE COMPARTMENT (Fig. 18) The scroll saw has the storage compartment (A) that is located under the right side of the work table.
TROUBLESHOOTING PROBLEM PROBLEM CAUSE CORRECTIVE ACTION Motor will not run. • Defective cord, plug or outlet. • Defective motor.
