GENERAL SAFETY RULES
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your
item works. The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS
WORK AREA SAFETY
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
- Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of elec-tric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
- If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. The use of a GFCI reduces the risk of elec-tric shock.
PERSONAL SAFETY
- Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inatten-tion while operating power tools may result in serious personal injury.
- Use personal protective equipment. Always wear eye protection. Protective equipment such as a respiratory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of personal injury.
- Prevent unintentional starting. Ensure the switch is in the off-position before connecting to the power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
- Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your
item works. The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS
- If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
- Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
- Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

- Do not use dull or bent blades.
- When cutting a large workpiece, make sure the material is supported at the table height.
- Turn the saw OFF and unplug the power cord if the blade jams in the workpiece. This condition is usually caused by sawdust clogging the line you are cutting. Wedge open the workpiece and back out the blade after turning off and unplugging the machine.
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 under ALL local codes
and ordinances.
- Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a licensed electrician.
- Improper connection of the equipment grounding conductor can result in electric shock. The conductor with the green insulation (with or without yellow stripes) is the 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 licensed electrician or service personnel if you do not completely understand the grounding instructions or whether the tool is properly grounded.
- Use only three-wire extension cords that have three-pronged plugs and outlets that accept the tool’s plug (INSERT CR). Repair or replace a damaged or worn cord immediately.
CAUTION! In all cases, make certain the outlet in question is properly
grounded. If you are not sure, have a licensed electrician check the outlet.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one 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 and overheating. The table below shows the
correct size to be used according to cord length and ampere rating. When in
doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
AMPERAGE | REQUIRED GAUGE FOR EXTENSION CORDS |
---|---|
25 ft. | 50 ft. |
1.2A | 18 gauge |
- Examine the extension cord before use. 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 person before using it.
- Do not abuse the extension cord. Do not pull on the cord to disconnect from the receptacle; always disconnect by pulling on the plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
- Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be protected with a 15A time-delayed fuse. 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 the motor.

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.”
ALIGN THE BEVEL INDICATOR
The bevel indicator has been adjusted at the factory but should be rechecked
before use for best operation.
- Remove the blade guard foot (Fig. 2 – 1), using a Phillips head screwdriver (not included) to loosen the screw (Fig. 2 – 2).
- Loosen the table bevel lock knob (Fig. 3 – 1) and bevel the table until it is approximately at a right angle to the blade.
- Loosen the locking nut (Fig. 4 – 1) on the table adjusting the screw (Fig. 4 – 2) under the table by turning it counter-clockwise. Lower the table adjusting the screw by turning it clockwise.
- Use a combination square (Fig. 5 – 1) to set the table exactly 90° to the blade (Fig. 5 – 2). If there is space between the square and the blade, adjust the table angle until the space is closed.
- Lock the table bevel lock knob (Fig. 3 – 1) under the table to prevent movement.
- Tighten the adjusting screw (Fig. 4 – 2) under the table until the head of the screw touches the table. Tighten the lock nut (Fig. 4 – 1).
- Loosen the screw (Fig. 3 – 2) holding the bevel scale pointer and position the pointer to 0°. Tighten the screw.
- Attach the blade guard foot (Fig. 2 – 1) so the foot rests flat against the table. Tighten the screw (Fig. 2 – 2) using a Phillips head screwdriver (not included).
NOTE: Avoid setting the edge of the table against the top of the motor.
This can cause excess noise when the saw is running.
BENCH MOUNTING THE SAW
Before operating the saw, it must be firmly mounted to a workbench or another
rigid frame. Use the base of the saw to mark and pre-drill the mounting holes
on the mounting surface. If the saw is to be used in one location, permanently
secure it to the work surface. Use wood screws if mounting to wood. Use bolts,
washers, and nuts if mounting into metal. To reduce noise and vibration,
install a soft foam pad (not supplied) between the scroll saw and the
workbench.
NOTE: Mounting hardware is not included.
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. Make sure there is adequate room for handling and properly supporting the workpiece.
BLADE GUARD FOOT ADJUSTMENT
When cutting at angles, the blade guard foot should be adjusted so it is
parallel to the table and rests flat above the workpiece.
- To adjust, loosen the screw (Fig. 6 – 1), tilt the foot (Fig. 6 – 2) so it is parallel to the table, and tighten the screw.
- Loosen the height adjustment knob (Fig. 7 – 1) to raise or lower the foot until it just rests on top of the workpiece. Tighten the knob.
ADJUSTING THE DUST BLOWER
For best results, the dust blower tube (Fig. 8 – 1) should be adjusted to
direct air at both the blade and the workpiece.
DUST COLLECTION PORT
A hose or vacuum accessory (not provided) should be connected to the dust
chute (Fig. 9 – 1). If excessive sawdust buildup occurs inside the base, use a
wet/dry vacuum cleaner or manually remove sawdust by unlocking both side panel
knobs and opening the side panel open. Once the sawdust is removed, close the
side panel and re-lock both knobs to ensure safe and efficient cutting.
- Dust Port Inner Diameter: 1.21 in. (30.85mm)
- Dust Port Outer Diameter: 1.40 in. (35.53 mm)
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. Use this table as an example, but with practice, per-sonal preference will be the best selection method.
- When choosing a blade, use very fine, narrow blades to scroll cut in thin wood 1/4″ thick or less.
- Use wider blades for thicker materials
- NOTE: This will reduce the ability to cut tight curves. A smaller blade width can cut circles with smaller diameters.
- NOTE: Thinner blades will tend to deflect more when making bevel cuts.
Teeth per Inch| Blade Width| Blade Thickness|
Blade SPM| Material Cut
---|---|---|---|---
10 to 15| 0.11″| 0.018″| 500 to 1200 SPM| Medium turns on 1/4″ to 1-3/4″ wood,
soft metal, hardwood
15 to 28| 0.055″ to 0.11″| 0.01″ to 0.018″| 800 to 1700 SPM| Small turns on
1/8″ to 1-1/2″ wood, soft metal, hardwood
BLADE CARE
To maximize the life of your scroll saw blades:
- Do not bend blades when installing.
- Always set proper blade tension.
- Use the right blade (see instructions on replacement blade packaging for proper use).
- Feed the work correctly into the blade.
- Use thin blades for intricate cutting.
CAUTION! Any and all servicing should be performed by a qualified service centre.
WARNING! To prevent personal injury, always turn the saw OFF and disconnect the plug from the power source before changing blades or making 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.
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.
TIP: The table insert can be removed during blade changes to provide more
access to the blade holders, but this is not mandatory. The table insert
should always be replaced before using the saw.
REMOVING THE BLADE
-
To remove the blade, relieve the tension on it by lifting the blade tension lever (Fig. 11 – 1). If necessary, turn the lever counterclockwise to loosen the blade holder further.
-
Unlock both the front locking knob (Fig. 12 – 1) and the back locking knob (Fig. 12 – 2) and open the side panel.
-
Remove the blade from the blade holders (Fig. 13 – 1).
- For a pinned blade, push down on the upper blade holder to remove the blade from the upper blade holder and then remove the blade from the lower blade holder.
- For a pinless blade, ensure that there is slack in the blade and it is not tensioned. Loosen the thumbscrews (Fig. 13 – 2) in the top and bottom blade holders and remove the blade from the holders.
INSTALLING THE BLADE
-
Install the blade on the blade holders (Fig. 13 – 1).
For Pinned Blade:
CAUTION: Install the blade with the teeth pointing downward.
| For Pinless Blade:
CAUTION: Install the blade with the teeth pointing downward.
---|---
• Hook the blade pins in the recess of the lower blade holder.
• While pushing down on the upper blade holder (Fig. 13 – 1), insert the blade pins into the recess of the upper blade holder.
| • Ensure the thumbscrew (Fig. 13 – 2) on the lower blade holder is loose and insert the blade into the opening of the lower blade holder.
• Secure the blade in the lower blade holder by tighten- ing the thumb screw.
TIP: Thread the workpiece through the pilot hole of the workpiece if making an interior cut.
| • Ensure the thumbscrew (Fig. 13 – 2) on the upper blade holder (Fig. 13 – 1) is loose and insert the blade into the opening of the upper blade holder.
• Secure the blade in the upper blade holder (Fig. 13 – 1) by tightening the thumb screw.
- Push the tension lever down and make sure the blade is properly positioned.
- Turn the tension lever clockwise until the desired tension in the blade is achieved. TIP: A properly-tensioned blade will make a high-C sound (C6, 1047 Hz) when plucked with a finger. A brand-new blade will stretch when first tensioned, and may require adjustment.
- Close the side panel and secure it by locking both the front (Fig. 12 – 1) and back (Fig. 12 – 2) locking knobs.
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 cut-ting operations. Please read and
understand the following directions 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 and poor cutting performance. Let the tool do the work.
- The blade teeth cut material ONLY on the down stroke. Ensure the blade teeth point downwards.
- Guide the wood into the blade slowly. Again, let the tool do the work.
- There is a learning curve for each person using this saw. During that period, expect some blades to break as you get the hang of using the saw.
- Best results are achieved when cutting wood one inch thick or less.
- When cutting wood thicker than one inch, guide the wood slowly into the blade and take extra care not to bend or twist the blade while cutting, in order to maximize blade life.
- Teeth on scroll saw blades wear out, and the blades 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 the type of cut, wood species, etc.
- To get accurate cuts, be prepared to compensate for the blade’s tendency to follow the wood grain.
- This scroll saw is primarily designed to cut wood or wood products. For cutting precious and non-ferrous metals, the variable control switch must be set at very slow speeds.
- When choosing a blade, use very fine, narrow blades to scroll cut in thin wood 1/4” thick or less. Use wider blades for thicker materials. This, however, will reduce the ability to cut tight curves.
- Blades wear down faster when cutting plywood or very abrasive particle board. Angle cutting in hardwoods also wears blades down faster.
ON/OFF & SPEED CONTROL SWITCH
Always wait for the saw to come to a complete stop before re-starting.
- 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.
- 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.
- To turn the saw off, flip the ON/OFF switch back to OFF.
- To lock the switch in the OFF position, remove the yellow safety key from the switch. This will prevent accidental opera-tion. Store the safety key in a safe place.
WARNING! Remove the safety key whenever the drill is not in use. Place
the key in a safe place and out of the reach of children.
WARNING! To avoid injury from accidental start-ups, always turn the
switch OFF and unplug the scroll saw before moving the tool, replacing the
blade, or making adjustments.
FREEHAND CUTTING
-
Lay out desired design, or secure design to the workpiece.
-
Raise the blade guard foot (Fig. 15 – 1) by loosening the height adjustment knob (Fig. 15 – 2).
-
Position the workpiece against the blade and place the blade guard foot against the top surface of the workpiece.
-
Secure the blade guard foot (Fig. 15 – 1) by tightening the height adjustment knob (Fig. 15 – 2).
-
Remove the workpiece from the blade prior to turning the scroll saw ON.
CAUTION! Always make sure the blade is not in contact with the workpiece before turning the saw ON. -
Slowly feed the workpiece into the blade while holding the workpiece securely against the table.
CAUTION! Do not force the leading edge of the workpiece into the blade. The blade will deflect, reducing accuracy of cut, and may break. -
When cutting is complete, move trailing edge of the workpiece beyond the blade guard foot. Turn the switch OFF.
ANGLE CUTTING (BEVELING)
- Layout or secure design to workpiece.
- Move the blade guard foot (Fig. 16 – 1) to the highest posi-tion by loosening the height adjustment knob (Fig. 16 – 2) and retighten.
- 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).
- Tighten the table bevel lock knob (Fig. 16 – 3).
- Loosen the blade guard screw (Fig. 16 – 2), and tilt the blade guard (Fig. 16 – 1) to the same angle as the table. Retighten the blade guard screw.
- Position the workpiece on the right side of the blade. Lower the blade guard foot against the surface by loosening the height adjustment knob. Retighten.
- Follow steps 5 to 7 under Freehand cutting.
INTERIOR CUTTING & FRETWORK (FIG. 17)
-
Lay out the design on the workpiece. Drill a 1/4″ pilot hole in the workpiece.
-
Remove the blade. See “BLADE REMOVAL AND INSTALLATION” on p. 13.
NOTE: If you are not changing blades, only remove the blade from the upper blade holder. Leave it installed in the lower blade holder. If you are changing blades, install the new blade in the lower blade holder. Do not secure it in the upper blade holder yet. -
Place the workpiece on the saw table, threading the blade through the hole in the workpiece. Secure the blade in the upper blade holder, as directed in “BLADE REMOVAL AND INSTALLATION” on p. 13.
-
Follow steps 3-7 under “FREEHAND CUTTING” on p. 15.
-
When finished making the interior scroll cuts, simply turn the scroll saw OFF. Unplug the saw and relieve blade tension before removing the blade from the upper blade holder. Remove the workpiece from the table.
RIP OR STRAIGHT LINE CUTTING
-
Raise the blade guard foot (Fig. 16 – 1) by loosening the height adjustment knob (Fig. 16 – 2).
-
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 workpiece against the blade and place the blade guard foot against the top surface of the workpiece.
-
Secure the blade guard foot in place by tightening the height adjustment knob.
-
Remove the workpiece from the blade prior to turning the scroll saw ON.
CAUTION! In order to avoid uncontrollable lifting of the workpiece and reduce blade breakage, do not turn the switch on while the workpiece is against the blade. -
Position the workpiece against the straight edge prior to touching the leading edge of the workpiece against the blade.
-
Slowly feed the workpiece into the blade, guiding the workpiece against the straight edge and pressing the workpiece down against the table.
CAUTION! Do not force the leading edge of the workpiece into the blade. The blade will deflect, reducing the accuracy of the cut, and may even break. -
When the cut is complete, move trailing edge of the workpiece beyond the blade guard foot. Turn the switch OFF.
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 sepa-rately) 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.
CARBON BRUSH REPLACEMENT
The wear on the carbon brushes depends on how frequently and how heavily the
tool is used. To maintain maximum efficiency of the motor, we recommend
inspecting the two carbon brushes every 60 hours of operation or when the tool
stops working. The carbon brushes can be found on the top and bottom of the
motor.
- Unplug the saw. To access the carbon brushes, remove the carbon brush cover with a flat-head screwdriver (not included). Turn the saw on its side to access the carbon brush cap on the bottom of the motor.
- Carefully remove the old carbon brushes using pliers. Keep track of which orientation the old carbon brushes were in to prevent needless wear if they will be reinstalled.
- Measure the length of the brushes. Install the new set of carbon brushes if either carbon brush length is worn down to 3/16” or less. Reinstall the old carbon brushes (in their original orientation) if your brushes are not worn down to 3/16” or less. Both carbon brushes should be replaced at the same time. Replacement carbon brushes (part 3920B-071-2) can be purchased from wenproducts.com.
- Replace the carbon brush cover.
NOTE: New carbon brushes tend to spark for a few minutes during the first use as they wear down.
LUBRICATION
Lubricate the arm bearings every 50 hours of use.
- Turn the saw on its side and remove the cover.
- Squirt a generous amount of SAE 20 oil (lightweight motor oil, sold separately) around the shaft and bearing.
- Let the oil soak in overnight.
- Repeat the above procedure for the opposite side of the saw.
- The other bearings on your saw are permanently sealed and require no additional lubrication.
BLADES
To maximize the life of your scroll saw blades:
- Do not bend blades when installing.
- Always set proper blade tension.
- Use the right blade (see instructions on replacement blade packaging for proper use).
- Feed the work correctly into the blade.
- Use thin blades for intricate cutting.
