SCROLL SAW SAFETY WARNINGS WARNING! Do not operate the power tool until you have read and understood the following instructions and the warning labels. BEFORE OPERATION 1. Check for both proper assembly and proper alignment of moving parts. 2. Understand the proper use of the ON / OFF switch. 3. Know the condition of the scroll saw. If any part is missing, bent, or does not operate properly, replace the component before attempting to operate the scroll saw. 4.
ELECTRICAL INFORMATION GROUNDING INSTRUCTIONS In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is properly installed and grounded in accordance with ALL local codes and ordinances. 1. Do not modify the plug provided.
UNPACKING & PACKING LIST UNPACKING With the help of a friend or trustworthy foe, such as one of your in-laws, carefully remove the scroll saw from the packaging and place it on a sturdy, flat surface.

KNOW YOUR SCROLL SAW TOOL PURPOSE Take on the most intricate and artful cuts with your WEN Scroll Saw. Refer to the following diagrams to become familiarized with all the parts and controls of your scroll saw. The components will be referred to later in the manual for assembly and operation instructions.
ASSEMBLY & ADJUSTMENTS NOTE: Prior to making adjustments, mount the scroll saw on a stable surface. See “Bench mounting the saw.” Fig. 2 ALIGN THE BEVEL INDICATOR The bevel indicator has been adjusted at the factory, but should be rechecked prior to use for best operation. 1 1. Remove the blade guard foot (Fig. 2 - 1), using a Phillips head screwdriver (not included) to loosen the screw (Fig. 2 - 2). 2 2. Loosen the table bevel lock knob (Fig.
ASSEMBLY & ADJUSTMENTS Fig. 6 WARNING! TO REDUCE RISK OF INJURY: • When carrying the saw, hold it close to your body to avoid injury to your back. Bend your knees when lifting the saw. • Carry the saw by the base. Do not carry the saw by the power cord or upper arm. • Secure the saw in a position where people cannot stand, sit, or walk behind it. Debris thrown from the saw could injure people standing, sitting, or walking behind it. Secure the saw on a firm, level surface where the saw cannot rock.
ASSEMBLY & ADJUSTMENTS BLADE SELECTION This scroll saw accepts 5" long 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 per inch. Always select the narrowest blades for intricate curve cutting and the widest blades for straight and large curve cutting operations. The table below represents suggestions for various materials.
ASSEMBLY & ADJUSTMENTS This saw uses pinned and pinless blades. Pinned blades are thicker for stability and for faster assembly. They provide faster cutting on a variety of materials. 1 Fig. 11 NOTE: When installing pinned 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 mechanism will keep it in place.
ASSEMBLY & ADJUSTMENTS Fig. 12 Fig. 13 2 1 2 1 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 directions before attempting to use the saw. 1. When feeding the workpiece into the blade, do not force it against the blade. This could cause blade deflection and poor cutting performance. Let the tool do the work. 2.
OPERATION ON/OFF & SPEED CONTROL SWITCH Fig. 14 Always wait for the saw to come to a complete stop before restarting. 1. To turn the saw on, flip the ON/OFF switch (Fig. 14 - 1) to ON. When first starting the saw, it is best to move the speed control knob (Fig. 14 - 2) to the middle speed position. 2 2. Adjust the blade speed to the desired setting between 400 to 1600 strokes per minute (SPM). Turning the control knob clockwise increases speed; turning it counterclockwise reduces speed. 1 3.
OPERATION ANGLE CUTTING (BEVELING) Fig. 16 1. Layout or secure design to workpiece. 2. Move the blade guard foot (Fig. 16 - 1) to the highest position by loosening the height adjustment knob (Fig. 16 - 2) and retighten. 2 1 3. Tilt the table to the desired angle by loosening the table bevel lock knob (Fig. 16 - 3). Move the table to the proper angle using the degree scale and the pointer (Fig. 16 - 4). 4. Tighten the table bevel lock knob (Fig. 16 - 3). 5. Loosen the blade guard screw (Fig.
OPERATION RIP OR STRAIGHT LINE CUTTING 1. Raise the blade guard foot (Fig. 16 - 1) by loosening the height adjustment knob (Fig. 16 - 2). 2. Measure from the tip of the blade to the desired distance. Position the straight edge parallel to the blade at that distance. 3. Clamp the straight edge to the table. 4. Recheck your measurements using the workpiece to be cut and make sure the straight edge is secure. 5.
MAINTENANCE WARNING! Always turn the switch OFF and unplug the power cord from the outlet before maintaining or lubricating the scroll saw. To ensure that the wood glides smoothly across the work surface, periodically apply a coat of paste wax (sold separately) to the surface of the worktable. If the power cord is worn out or damaged in any way, replace it immediately. Do not attempt to oil the motor bearings or service the motor’s internal parts.
