GENERAL SAFETY RULES 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 THESE INSTRUCTIONS WORK AREA Keep your work area clean and well lit. Cluttered benches and 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 which may ignite the dust or fumes.
GENERAL SAFETY RULES SERVICE Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of shock or injury.
SYMBOLS Important: Some of the following symbols may be used on this tool. Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the tool better and safer.
ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Your Ryobi power tool is double insulated. This means you are separated from the tool's electrical system by two complete sets of electrical insulation. This extra layer of insulation is intended to protect the user from electrical shock due to a break in the wiring insulation. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

FEATURES KNOW YOUR PLATE JOINER See Figure 2. Except for the dust bag, your plate joiner has been shipped completely assembled and ready for use. An operator's manual and warranty registration are also included. Inspect your new plate joiner carefully to make sure no breakage or damage has occurred during shipping. If any parts are damaged or missing, contact your local Ryobi factory or authorized service center to obtain replacement parts before attempting to operate your plate joiner.
ADJUSTMENTS WARNING: If any parts are missing, do not operate tool until the missing parts are replaced. Failure to do so could result in possible serious personal injury. ROTATE TO DESIRED SETTING 0, 10, OR 20 PULL AND HOLD TO ROTATE DEPTH ADJUSMENT KNOB DEPTH OF CUT ADJUSTMENTS Your plate joiner can be adjusted to three standard cutting depths to accommodate three standard size biscuits — #0, #10, and #20. Adjustments are made by engaging slots on depth adjustment knob with tabs on rear base assembly.
ADJUSTMENTS FENCE HEIGHT ADJUSTMENT See Figure 5. The adjustable fence on your plate joiner can be moved up and down to adjust the position of the blade in relation to the top of the workpiece. A scale on both sides of the fence indicates the height of the fence from the center of the blade. The fence can be positioned up to two inches from the center of the blade. However, the scale and indicator point can only be set up to 1-1/2 in. from the center of the blade. Scale marks are in increments of 1/16 in.
OPERATION WARNING: Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury. A variety of spline joints can be made using your plate joiner. The number and size biscuits needed for each joint depends on the thickness of the wood and the length of the joint. In general, the small #0 biscuits should be used for miter cuts in 3/4 in. materials.
OPERATION Finally, disassemble the workpieces and place a bead of glue in each slot. Also, spread a bead of glue over the entire surface of the joint. Reinsert the biscuits and assemble the workpieces. See Figure 8. Clamp workpieces together until the glue sets up. BUTT JOINTS See Figure 9. A butt joint is one of the weakest joints in woodworking. This type of joint is mating the end grain of one board with the edge grain of another. The bonding of glue on this type of surface is poor.
OPERATION OFFSET BUTT JOINTS See Figure 10. The rails of a table or workbench are often offset from the front of the table legs. When offsets are required, it is necessary to cut the slots in the rails first, then re-adjust the fence to cut the slots in the legs. Keeping this one exception in mind, the procedure for cutting offset butt joints is identical to the procedure for cutting butt joints. For example — If a 1/4 in.
OPERATION Place your plate joiner on vertical board as shown in figure 15 and align indicator marks on base assembly with centerline on vertical board. Place a straight piece of wood on the vertical board and securely clamp it flush against the base assembly. This piece of wood is used for a fence or guide. It must be square with the sides of the vertical board and parallel with the centerline. Align centerline on bottom of base assembly with marked intersection for biscuit slot.
OPERATION Align indicator mark on fence with the centerline on the workpiece. Plug your plate joiner into power supply and prepare to cut slot. Depress the switch trigger to turn the power on your plate joiner, then push it forward to extend the blade into the wood. When the base assembly bottoms out against the depth of cut adjustment knob setting, pull back releasing pressure on the spring. Blade will retract from biscuit slot.
OPERATION Once all slots have been cut, place a biscuit in each joint and dry assemble the workpieces. Make sure each joint lines up and fits. Finally, disassemble workpieces and place a bead of glue in each slot. Also, spread a bead of glue over the entire surface of the joint. Reinsert the biscuits and assemble workpieces. See Figure 17. Clamp workpieces together until the glue sets up.
MAINTENANCE WARNING: ADJUSTABLE FENCE When servicing, use only identical Ryobi replacement parts. Use of any other part may create a hazard or cause product damage. TO REMOVE FRONT BASE ASSEMBLY CLEANING BASE ASSEMBLY / DUST BAG TUNNEL See Figures 21-23. After extended use, wood particles and resin may build up inside the base assembly of your plate joiner and clog the path for wood particles going into dust bag.
MAINTENANCE BLADE REPLACEMENT See Figures 24-27. After extended use, the blade on your plate joiner may become dull and need replacing. If you accidentally hit a nail or other blunt object, it will break the carbide tips on the blade. These situations also require replacing the blade. ADJUSTABLE FENCE TO REMOVE FRONT BASE ASSEMBLY HOW TO REPLACE THE BLADE Unplug your plate joiner.
MAINTENANCE HOW TO REPLACE THE BLADE (Continued) NOTE: Blade teeth point toward the right of the tool when held in normal operating position. The direction of rotation is marked on the joiner blade. An arrow on the bottom of the front base assembly also indicates direction of rotation. See Figure 24. Tighten blade screw securely. NOTE: Turn blade screw clockwise to tighten. Replace rear base assembly. Position adjustment rod in its proper place as shown in figure 25.
TROUBLESHOOTING PROBLEM SOLUTION 1. Biscuits do not fit slots. Biscuits not fitting slots may also cause misalignment of boards being joined. A. Biscuit slots are too deep or too shallow. Make fine adjustments to depth setting. See "TO MAKE FINE ADJUSTMENTS" section on page 9. B. Biscuit thickness may be out of tolerance. Compress biscuits in a vise if they are too thick. C. Check to see if biscuits are the correct size for the size slots that have been cut: #0, #10, or #20. D.
