It’s safer than using your hand and it frees both hands to operate the tool. ■ ■ DO NOT OVERREACH. Keep proper footing and balance at all times. Page 4 NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the blade is unintentionally contacted. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and 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 its operation. A guard or other part that is damaged must be properly repaired or replaced by an authorized service center to avoid risk of personal injury. DIRECTION OF FEED. Feed work into a blade or cutter against the direction or rotation of the blade or cutter only. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop. DON’T ABUSE CORD. Never carry tool by the cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges. PROTECT YOUR LUNGS. Wear a face or dust mask if the cutting operation is dusty. PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation. WARNING: Blade coasts after turn off. KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND GREASE. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to clean tool. INSPECT TOOL CORDS AND EXTENSION CORDS PERIODICALLY and, if damaged, have repaired by a qualified service technician. Stay constantly aware of cord location and keep it well away from the rotating wheel. NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor could ignite fumes. USE ONLY OUTDOOR EXTENSION CORDS with approved ground connection that are intended for use outdoors and so marked. BE SURE THE BLADE PATH IS FREE OF NAILS. Inspect for and remove nails from lumber before cutting. RULES FOR SAFE OPERATION ■ AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your hand to move into the blade. ALWAYS make sure you have good balance. ■ ALLOW THE MOTOR TO COME UP TO FULL SPEED before starting a cut to avoid binding or stalling. ■ DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches replaced by an authorized service center. ■ REPLACEMENT PARTS. All repairs, whether electrical or mechanical, should be made by qualified service technician at an authorized service center. WARNING: When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage. ■ KEEP HANDS AWAY FROM CUTTING AREA. Do not hand hold pieces so small that your fingers go under the blade guard. Do not reach underneath work or in blade cutting path with your hands and fingers for any reason. ■ FIRMLY CLAMP OR BOLT your saw to a stable, level workbench or table. The most comfortable table height is approximately waist height. ■ DO NOT FEED THE MATERIAL TOO QUICKLY. Do not force the workpiece against the blade. ■ USE ONLY CORRECT BLADES. Use the right blade size, style and cutting speed for the material and the type of cut. Blade teeth should point down toward the table. ■ BEFORE MAKING A CUT, BE SURE ALL ADJUSTMENTS ARE SECURE. ■ ALWAYS SUPPORT LARGE WORKPIECES while cutting to minimize risk of blade pinching and kickback. Saw may slip, walk or slide while cutting large or heavy boards. ■ DO NOT REMOVE JAMMED CUTOFF PIECES until blade has stopped. ■ NEVER START THE TOOL when the blade is in contact with the workpiece. ■ NEVER TOUCH BLADE or other moving parts during use. ■ BEFORE CHANGING THE SETUP, REMOVING COVERS, GUARDS, OR BLADES, unplug the saw and remove the switch key. ■ KEEP BLADES CLEAN, SHARP, AND WITH SUFFICIENT SET. Sharp blades minimize stalling and kickbacks. ■ ALWAYS TURN OFF SAW before disconnecting it to avoid accidental starting when reconnecting to a power source. ■ DO NOT OPERATE THIS TOOL WHILE UNDER THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY MEDICATION. ■ STAY ALERT AND EXERCISE CONTROL. Watch what you are doing and use common sense. Do not operate tool when you are tired.

Refer to them frequently and use them to instruct other users. If you loan someone this tool, loan them these instructions also. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. SAVE THESE INSTRUCTIONS Page 5 ELECTRICAL EXTENSION CORDS ELECTRICAL CONNECTION Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used. Length of Extension Cord Wire Size (A.W.G.) Up to 25 feet 16 26-100 feet 16 When working with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters WA on the cord's jacket. Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation. Your Ryobi Scroll Saw is powered by a precision built electric motor. It should be connected to a power supply that is 120 volts, 60Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the saw does not operate when plugged into an outlet, double check the power supply. CAUTION: Keep the cord away from the cutting area and position the cord so that it will not be caught on lumber, tools, or other objects during cutting. GROUNDING INSTRUCTIONS In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having 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. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green 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 qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately. This tool is intended for use on a circuit that has an outlet like the one shown in Figure 1. It also has a grounding pin like the one shown.

CLAMPING SCROLL SAW TO WORKBENCH Apply a coat of paste wax to the saw table surface to allow the workpiece to slide easily across the surface. Wipe the saw table thoroughly with a dry cloth to remove excess wax. If the scroll saw is to be used in a portable application, it is recommended that you fasten it permanently to a mounting board that can easily be clamped to a workbench or other supporting surface. The mounting board should be of sufficient size to avoid tipping of saw while in use. Any good grade plywood or chipboard with a 3/4 in. (19 mm) thickness is recommended. ■ Mount saw to board using holes in saw base as a template for hole pattern. Locate and mark the holes where scroll saw is to be mounted. ■ Follow last three steps in previous section called Mounting Scroll Saw to Workbench. If lag bolts are being used, make sure they are long enough to go through holes in the saw base and the material the saw is being mounted to. MOUNTING SCROLL SAW TO WORKBENCH WARNING: To avoid serious personal injury from unexpected tool movement, always securely mount scroll saw to a workbench. 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. ■ Each hole in the base of the saw should be bolted securely using machine bolts, washers, and nuts (not included). Bolts should be of sufficient length to accommodate the saw base, washers, nuts, and the thickness of the workbench. ■ Place scroll saw on workbench. Using the saw base as a pattern, locate and mark the holes where the scroll saw is to be mounted. ■ Drill four holes through the workbench. ■ Place scroll saw on workbench aligning holes in the saw base with the holes drilled in the workbench. ■ Insert all four bolts (not included) and tighten securely with washers and nuts (not included). Note: All bolts should be inserted from the top. Install the washers and nuts from the underside of the bench. If machine bolts are being used, make sure they are long enough to go through holes in the saw base, the material the saw is being mounted to, and the washers and nuts. Note: It may be necessary to countersink washers and nuts on the bottom side of mounting board. 30 Supporting surface where scroll saw is mounted should be examined carefully after mounting to insure that no movement during use can result. If any tipping or walking is noted, secure workbench or supporting surface before beginning cutting operations. See Figure 5. 15 0 C-CLAMP Reducing Noise and Vibration: You may wish to place a foam pad or piece of carpet between the saw base and the workbench to help reduce noise and vibration. If a foam pad or piece of carpet is used, do not overtighten the mounting bolts. Leave some cushion between the padding and the saw base to help absorb the noise and vibration. The size of the padding material should be approximately 24 in. x 12 in. x 1/2 in. (610 mm x 305 mm x 13 mm).

Failure to turn the saw off, remove the switch key, and unplug the saw from the power source could result in accidental starting causing possible serious injury. A bevel scale is located under the saw table as a convenient guide for setting the approximate saw table angle for bevel cutting. When greater precision is required, make practice cuts on scrap material and adjust the saw table as necessary for your requirements. Note: When cutting at angles, the drop foot should be tilted so it is parallel to the saw table and rests flat against the workpiece. To tilt the drop foot, loosen phillips screw, tilt drop foot to the proper angle, then retighten screw. ■ Turning the blade tension knob counterclockwise decreases (or loosens) blade tension. ■ Turning the blade tension knob clockwise increases (or tightens) blade tension. Note: Adjustments to blade tension can be made at any time. Check tension by the sound the blade makes when plucked like a guitar string. This method of adding tension to the blade can be developed with practice and requires knowing your scroll saw. ■ Pluck the back straight edge of blade while turning tension adjusting knob. Sound should be a musical note. Sound becomes less flat as tension increases. Sound decreases with too much tension. Note: Be careful not to adjust blade too tight. Too much tension may cause the blade to break as soon as you start cutting. Too little tension may cause the blade to bend or break before the teeth wear out.

WARNING: Failure to turn the saw off, remove the switch key, and unplug the saw from the power source could result in accidental starting causing possible serious injury. BLADE CLAMP SCREW Fig. 10 Page 13 OPERATION BASIC OPERATION OF THE SCROLL SAW Before starting a cut, watch the saw run. If you experience excessive vibration or unusual noise, stop immediately. Turn the saw off, remove the switch key, and unplug the saw. Do not restart until locating and correcting the problem. Note: After the saw is turned ON, a hesitation before blade movement is normal. CUTTING PROCEDURES ■ 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 and adjust the saw. ■ Plan the way you will hold the workpiece from start to finish. ■ Keep your hands away from the blade. Do not hand hold pieces so small your fingers will go under the blade guard. ■ Hold the workpiece firmly against the saw table. ■ The blade teeth cut material only on the down stroke. ■ Use gentle pressure and both hands when feeding the work into the blade. Do not force the work. ■ Guide the workpiece into the blade slowly because the teeth of the blade are very small and can only remove material on the down stroke. ■ Avoid awkward operations and hand positions where a sudden slip could cause serious injury from contact with the blade. Never place hands in blade path. ■ To get accurate cuts, compensate for the blade's tendency to follow the wood grain as you are cutting wood. ■ Use extra supports (tables, saw horses, blocks, etc.) when cutting large, small or awkward workpieces. ■ Never use another person as a substitute for a table extension or as additional support for a workpiece that is longer or wider than the basic saw table. ■ When cutting irregularly shaped workpieces, plan your work so it will not pinch the blade. Workpieces must not twist, rock or slip while being cut. WARNING: Before removing loose pieces from the table, turn saw off and wait for all moving parts to stop to avoid serious personal injury. AVOIDING INJURY ■ Make sure saw is level and does not rock. Saw should always be on a firm, level surface with plenty of room for handling and properly supporting the workpiece. ■ Bolt saw to the support surface to prevent slipping, walking or sliding during operations like cutting long, heavy boards. ■ Turn saw off, remove switch key, and unplug cord from the power source before moving the saw. ■ Do not remove jammed cutoff pieces until blade has come to a full and complete stop. ■ Choose the right size and style blade for the material and type of cut you plan to do. ■ Use only recommended accessories. ■ With the exception of the workpiece and related support devises, clear everything off the saw table before turning the saw on. ■ Properly support round materials such as dowel rods or tubing because they have a tendency to roll during a cut causing the blade to “bite”. To avoid this, always use a “V” block or clamp workpiece to a miter gauge ■ Before removing loose pieces from the saw table, turn saw off and wait for all moving parts to stop. LOCKING THE SWITCH See Figure 11. ■ Wait until the saw has come to a full and complete stop. ■ Place the switch in the OFF position, remove the switch key from the switch assembly. Store key in a safe place. REMOVING JAMMED MATERIAL SWITCH SWITCH KEY 0N OFF REMOVE K TO LOC 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, remove the switch key from the switch assembly. Store key in a safe place. ■ Unplug the saw from the power source. ■ Remove the saw's blade and the workpiece, see section on Removing the Saw Blade, page 13. ■ Wedge the kerf open with a flat screwdriver or wooden wedge then remove the blade from the workpiece. ON Fig. 11 Page 14 OPERATION CHOICE OF BLADE AND SPEED The scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other fibrous materials. Your saw uses 5 in. long blades of either the pin end or the plain end style. The blade width and thickness and the number of teeth per inch to use are determined by the type of material and the size of the radius being cut. Note: As a general rule, always select narrow blades for intricate curve cutting and wide blades for straight and large curve cutting. Teeth/Inch Width Thickness Speed or Strokes Per Minute 10 .110 in. (2.8 mm) .020 in. (0.5 mm) 1200-1600 15 .110 in. (2.8 mm) .020 in. (0.5 mm) 600-1200 18 .095 in. (2.4 mm) .010 in. (0.3 mm) 400-600 Material Cut Popular size for cutting hard and soft woods 3/16 in. (4.8 mm) up to 2 in. (51 mm) Plastics, paper, felt, bone, etc. Wood, plastics, extremely thin cuts on materials 3/32 in. (2.4 mm) to 1/2 in. (13 mm) thick. For tight radius work in thin materials 3/32 in. (2.4 mm) to 1/8 in. (3 mm) wood, veneer, bone, fiber, ivory, plastic, etc. BLADE INFORMATION See Figure 12. ■ By turning the variable speed knob, the saw's speed may be adjusted from a high speed of approximately 1600 SPM (Strokes Per Minute) to a low speed of approximately 400 SPM. ■ To increase the strokes per minute, turn the variable speed knob clockwise or to the right. ■ To decrease the strokes per minute, turn the variable speed knob counterclockwise or to the left. Page 15 ON USING VARIABLE SPEED OFF ■ Scroll saw blades wear out and 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 type of material and speed of operation. ■ In cutting wood, best results are achieved when cutting wood less than one inch thick. ■ When cutting wood thicker than one inch, the user must guide the workpiece very slowly into the blade and take extra care not to bend or twist the blade while cutting. ■ When choosing a blade, carefully consider the following: • Very fine, narrow blades should be used to scroll cut in thin material 1/4 in. (6 mm) thick or less. • Most blade packages state the size or thickness and type of material which that blade is intended to cut. The package should also state the radius or size of curve that can be cut with that blade size. • Wider blades cannot cut curves as tight or as small as thinner blades. ■ Blades wear faster when: • Cutting plywood, hardwood, and other laminates. • Cutting material thicker than 3/4 in. (19 mm). • Side pressure is applied to the blade. TO INCREASE TO DECREASE Fig. 12 OPERATION WARNING: To avoid possible serious injury from accidental starting, always turn the saw off, remove the switch key, and unplug the saw from power source before removing or replacing the blade. DRILL HOLE INTERIOR CUT SCROLL CUTTING For general type scroll cutting, follow the pattern lines by pushing and turning the workpiece at the same time. Do not try to turn the workpiece while engaged in the blade without pushing it – the workpiece could bind or twist the blade. WARNING: 30 To prevent serious personal injury, never leave the saw unattended until the blade has come to a complete stop. WORKPIECE 15 0 INTERIOR SCROLL CUTTING See Figure 13. ■ One feature of a scroll saw is that it can be used to make scroll cuts on the interior of a workpiece without breaking or cutting through the edge or perimeter of the board. ■ To make interior cuts in the workpiece, remove the scroll saw blade as explained in the section on Installing Blades on page 13. ■ Drill a 1/4 in. (6 mm) hole in the workpiece. ■ Place the workpiece on the saw table with the drilled hole over the access hole in the table. ■ Install blade through the hole in the workpiece; adjust the drop foot and blade tension. ■ When finished making the interior scroll cuts, simply remove the blade from the blade holders as described in the section on Installing Blades, page 13, and remove the workpiece from the saw table. Fig. 13 WARNING: To avoid possible, serious personal injury, do not cut more than one loose piece of material at a time. WARNING: Do not allow familiarity with your saw to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury. STACK CUTTING See Figure 14. After becoming well acquainted with your saw through practice and experience, you may wish to try stack cutting. Stack cutting may be used when several identical shapes need to be cut. Several pieces of wood may be stacked on top and secured to each other before cutting. The wood pieces may be joined together by placing double sided tape between each piece or by wrapping masking tape around the corners or ends of the stacked wood. You must attach the stacked pieces of wood to each other so they will move on the table as a single piece of material. TAPE 30 WOOD PIECES 15 0 Fig. 14 Page 16 MAINTENANCE MOTOR BRUSHES WARNING: When servicing, use only identical Ryobi replacement parts. Use of any other part may create a hazard or cause product damage. GENERAL MAINTENANCE ■ Keep your scroll saw clean. ■ After cleaning the table top initially, apply a thin coat of automobile type (paste) wax to the table top so the wood slides easily while cutting. ■ Do not allow pitch to accumulate on the saw table. Clean with gum and pitch remover. ARM BEARINGS See Figure 15. Lubricate the arm bearings after the first 10 hours of use. Oil after every 50 hours of use or whenever there is a squeak coming from the bearings. ■ Carefully place the saw on its side as shown in Figure 15. Remove the rubber cap from the upper and the lower arm of the saw. ■ Squirt a few drops of SAE20 oil around the shaft end and arm bearings. Let oil soak in overnight, remaining in this position. Note: Lubricate the bearings on the other side of the saw in this same manner. See Figure 16. Your saw has externally accessible motor brush assemblies that should be checked periodically for wear. When one of the two brushes becomes worn, replace both brushes. ■ Unplug the saw from the power source. ■ Carefully place the saw on its side exposing the underside of the saw housing. ■ Using a flat blade screwdriver, remove the bottom brush assembly cap through the access hole in the base and the top brush assembly cap from the top of the motor. Gently pry the brush assemblies out using a small screw drivier, point of a nail, or paper clip. ■ If one motor brush is worn down shorter than 1/4 in. (6 mm), replace both motor brushes. Do not replace one side without replacing the other. Make sure curvature of brush matches curvature of motor and that the motor brush moves freely in brush tube. Use the blunt end of something thin (eraser end of pencil, etc.) to push the motor brush into the tube until it stays. ■ Make sure the motor brush cap is oriented correctly (straight). Tighten motor brush cap using a hand powered screwdriver only. Do not overtighten. WARNING: If the power cord is worn, cut, or damaged in any way, have it replaced immediately by a qualified service technician. Failure to do so could result in serious personal injury.
