DOUBLE INSULATION

Double insulation is a concept in safety, in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

WARNING:

The double insulated system is intended to protect the user from shock resulting from a break in the tool's internal wiring. Observe all normal safety precautions related to avoiding electrical shock.

IMPORTANT

Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service we suggest you return the tool to your nearest RYOBI AUTHORIZED SERVICE CENTER for repair. When servicing use only identical Ryobi replacement parts.

WARNING:

Do not attempt to operate this tool until you have read thoroughly and understand completely all instructions, safety rules, etc. contained in this manual. Failure to comply can result in accidents involving fire, electric shock, or serious personal injury. Save owner's manual and review frequently for continuing safe operation, and instructing others who may use this tool.

5. KEEP CHILDREN AND VISITORS AWAY. All visitors should wear safety glasses and be kept a safe distance from work area. Do not let visitors contact tool or extension cord.

6. STORE IDLE TOOLS. When not in use tools should be stored in a dry, high or locked-up place – out of the reach of children.

14. SECURE WORK. Use clamps or a vise to hold work. It's safer than using your hand and it frees both hands to operate tool.

15. DON'T OVERREACH. Keep proper footing and balance at all times. Do not use on a ladder or unstable support.

16. MAINTAIN TOOLS WITH CARE. Keep tools sharp at all times, and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

17. DISCONNECT TOOLS. When not in use, before servicing, or when changing attachments, blades, bits, cutters, etc., all tools should be disconnected.

18. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting wrenches are removed from tool before turning it on.

19. AVOID ACCIDENTAL STARTING. Don't carry plugged-in tool with finger on switch. Be sure switch is off when plugging in.

7. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was designed.

8. USE RIGHT TOOL. Don't force small tool or attachment to do the job of a heavy duty tool. Don't use tool for purpose not intended – for example – Don't use a circular saw for cutting tree limbs or logs.

9. DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and nonskid footwear are recommended when working outdoors. Also, wear protective hair covering to contain long hair and keep it from being drawn into air vents.

10. ALWAYS WEAR SAFETY GLASSES WITH SIDE SHIELDS. Everyday eyeglasses have only impact resistant lenses; they are NOT safety glasses.

11. PROTECT YOUR LUNGS. Wear a face or dust mask if operation is dusty.

12. PROTECT YOUR HEARING. Wear hearing protection during extended periods of operation.

13. DON'T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from heat, oil, and sharp edges.

20. MAKE SURE YOUR EXTENSION CORD IS IN GOOD CONDITION. 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. A wire gage size (A.W.G.) of at least 16 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

21. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords intended for use outdoors. Outdoor approved cords are marked with the suffix WA, for example - SJTW-A or SJOW-A.

22. KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kickback.

23. KEEP HANDS AWAY FROM CUTTING AREA. Keep hands away from blades. Do not reach underneath work while blade is rotating.

WARNING: BLADES COAST AFTER TURN OFF.

24. NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor

could ignite flammable liquids, gases, or fumes.

INTRODUCTION

Spline joinery is one of the strongest methods of joinery used in woodworking. When glue is properly applied to a spline and to the joint area of the wood pieces being connected, a large surface area receives the adhesion properties of the glue. This forms a very strong joint.

Traditional spline joinery requires cutting slots with a router or table saw. Small, thin strips of wood must then be cut to fit inside the slots and act as splines.

Newer methods of spline joinery use a plate or biscuit joiner to cut precise mating oval slots in adjoining boards. Your new biscuit joiner is a fast, simple, and accurate plunge cutting tool that can be used for this purpose. It can be used to cut slots in hardwood, softwood, plywood, particle board, and other pressed woods.

WARNING:

WEAR

YOUR

SAFETY

FORESIGHT IS BETTER

GLASSES

THAN NO SIGHT

The operation of any biscuit joiner can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power tool operation, always wear safety goggles or safety glasses with side shields and a full face shield when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses with side shields.

Football shaped wafers, called biscuits, are then placed inside the slots with glue and used to help line up adjoining surfaces. When a water based glue is used, the biscuits swell in the joint, making an extremely strong and firm bond. White glue, yellow glue, carpenters glue, hide glue, and aliphatic resin glue are examples of water based glues.

This bonding technique has traditionally been limited to making edge-to-edge joints. However, with the use of your new biscuit joiner, biscuits can now be easily used to connect butt, miter, and T-joints. Biscuit joining can be as strong as mortise and tenon, tongue and groove, standard spline, and doweled joints. In most cases the material around the biscuit will break before the biscuit itself will break. A greater surface area is exposed to glue in a biscuit joint, making the seams stronger.

Look for this symbol to point out important safety precautions. It means attention!!! Your safety is involved.

FEATURES

Your detail biscuit joiner has been designed for making fast, accurate, and simple plunge cuts in wood, etc. so that biscuits can be used to join two or more boards together. When used properly and only for what it is intended, this versatile tool will give you years of trouble-free performance. It is professionally engineered, but its ease of operation allows the amateur to produce beautiful and precise work.

#R1 = 7/32 in. x 5/8 in.

SWITCH

To turn your biscuit joiner ON, depress the switch trigger. Release switch trigger to turn your biscuit joiner OFF.

MOTOR

Your biscuit joiner has a powerful motor with sufficient power to handle tough cutting jobs. It develops a no load speed of 19,000 RPM.

BLADE

Your biscuit joiner has a 1-1/2 in. (38 mm) 6 tooth blade for cutting biscuit slots.

BISCUITS

See Figure 1.

Biscuits are available in three standard sizes:

#R1 (7/32 in. x 5/8 in.) #R2 (9/32 in. x 3/4 in.) #R3 (1/2 in. x 1 in.)

NOTE: Store biscuits in a dry place because they swell

rapidly upon contact with water-based woodworking glues.

REVERSIBLE FENCE FOR 45° AND 90° CUTS

Your biscuit joiner has a reversible fence. By loosening the height adjustment knobs, the fence can be removed through key hole slots. Once removed, it can be rotated 180° changing the angle of cut from 90° to 45° or vice versa. The height of the fence at 90° can be set between 0 to 3/4 in. from the center of the blade. The height of the fence at 45° can be set between 5/16 in. to 13/16 in. from the center of the blade.

The fence should always be used to guide and balance your biscuit joiner, providing ease of operation and maintaining safe control.

NONSKID BACKING PAD

The fence on your biscuit joiner is padded with a nonskid backing pad to hold it stationary against the workpiece. It helps prevent skidding when making cuts. It also prevents marring of the workpiece from biscuit joiner when cutting.

INDICATOR MARKS

Centerline and line of cut indicator marks have been provided on your biscuit joiner.

See Figure 2.

#R2 = 9/32 in. x 3/4 in.

#R3 = 1/2 in. x 1 in.

Fig. 1

APPLICATIONS

(Use only for the purpose listed below)

■ Cutting precise mating oval slots in hardwood, softwood, plywood, particle board, etc. for spline joinery applications.

ELECTRICAL CONNECTION

Your biscuit joiner has a precision built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, 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 your biscuit joiner does not operate when plugged into an outlet, double-check the power supply.

DEPTH ADJUSTMENT KNOB

A spring loaded depth adjustment knob makes it possible to make proper settings for three standard size biscuits. Fine adjustments to the cutting depth can be made with a knurled adjustment knob and jam nut located behind the depth adjustment knob. Once the correct depth setting has been made for one biscuit size, the other two depth settings will be automatically set.
