Receiving Open both shipping crates and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Before operating your jointer, read this instruction manual thoroughly for assembly, maintenance and safety instructions.
3. The stand can be secured to the floor using two anchor bolts (not provided) through the holes inside the bottom of the stand. Aligning Pulleys Place a straight edge against the motor pulley and cutterhead pulley to make sure they are aligned. If adjustment is necessary, loosen the set screws in the motor pulley, and slide it as needed until alignment is achieved. Re-tighten set screws. Mounting Drive Belt Figure 6 1. Place the belt into the groove of the cutterhead pulley. 2.
Electrical Connections Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury. The Jointer is equipped with either a single phase, 230 volt motor; or a three phase, 230/460 volt motor. The single phase unit is factory wired for 230 volts.
IMPORTANT: Make sure the electrical characteristics are the same on the motor nameplate and the power source, and make sure the circuit on which the jointer will be used is properly fused and that the wire size is correct. Converting from 230 Volt to 460 Volt (Three Phase Only) Consult the wiring diagram inside the starter box cover. A diagram is also included on pages 3738 of this manual. The Jointer must comply with all local and national codes after being wired. 1.
Adjustments Disconnect machine from power source before making adjustments. Tools required for adjustments: 8mm & 12mm wrenches 4mm hex wrench machinist's protractor or adjustable square steel straight edge Figure 12 Cutter Guard Removing Guard: Some adjusting procedures, as well as rabbeting operations, will require removal of the guard. Simply loosen handle on rabbeting ledge (Figure 12) and vertically lift guard out of the hole. Mounting Guard: The guard is spring tensioned.
Installing Knives Use care when working with or around sharp knives. Make sure power to the machine has been disconnected. When installing new knives, remove only one knife at a time. Clean the knife slot and install the new knife. Adjust and snug new knife in cutterhead before proceeding to next knife. 1. Disconnect machine from power source. 2. Remove the belt guard so that you can rotate the cutterhead by turning the motor pulley or by moving the drive belt.
7. Tightening the gib screws should be done in increments, to prevent any distortion to the cutterhead or buckling of knives. While holding the gauge down on one knife, snug down the five gib screws, beginning with the center screw and working your way to the ends. Do not fully tighten yet. 8. Rotate the cutterhead to the next slot and repeat step #6, only making the knives snug. Repeat for the third knife. 9.
6. Tighten the gib screws (A, Figure 18) then back them off approximately 1/4 turn or until the table moves freely, and re-set the lock nuts on the gib screws. If table will still not line up: Remove gib screws and table locking handle and remove gib (#16, page 29). Check gib to see that set screws do not go all the way through the gib or dimple the opposite side. If either of these conditions exist, replace with a new gib. Also, check to be sure the ways are clean and free of pitch and sawdust.
Setting Outfeed Table For accurate work in most jointing operations, the outfeed table must be exactly level with the knives at their highest point of revolution. 1. Raise the outfeed table to its highest point, and place a straight edge across it. 2. Rotate the cutterhead (using the belt or pulley) until one knife is at its highest point. 3. Lower the outfeed table until the straight edge contacts a knife. Rock the cutterhead slightly to make sure the apex of the knife is contacting the straight edge.
Fence Movement To slide the fence forward or backward on the table, loosen lock handle (A, Figure 24), slide the fence to desired position and tighten lock handle to secure fence. Lift up on fence when tilting or sliding, to prevent scratching the table. NOTE: The handle (A, Figure 24) may be adjusted to a more convenient position by loosening the hex nuts below the casting (see B, Figure 31), turning the handle to the proper position, and retightening the hex nuts. To tilt the fence forward: Figure 24 1.
45 degree forward stop: 1. The 45 degree forward stop is controlled by the screw (E, Figure 25). 2. Loosen the locking handle (B, Figure 25) and the hex nut on the screw (E, Figure 25). 3. Set the 45 degree protractor on the table and against the fence, and tilt the fence until it is flush against the 45 degree angle. 4. Rotate the screw (E, Figure 25) until it contacts the casting below it. 5. Tighten hex nut (E, Figure 25) and locking handle (B, Figure 25). Figure 25 (repeated) 45 degree back stop: 1.
Direction of Grain Avoid feeding work into the jointer against the grain. This will result in chipped and splintered edges (Figure 27). Feed with the grain to obtain a smooth surface (Figure 28). Hand Placement At the start of the cut, the left hand holds the work firmly against the infeed table and fence while the right hand pushes the work toward the knives. After the cut is under way, the new surface rests firmly on the outfeed table.
Edge Jointing This is the most common operation for the jointer. Set guide fence square with the table. Depth of cut should be the minimum required to obtain a straight edge. Do not make cuts deeper than 1/8" in a single pass. Hold the best face of the piece firmly against the fence throughout the feed. See Figure 30.
Taper Cuts A useful jointer operation is cutting an edge to a taper. The method can be used on a wide variety of work. Tapered legs of furniture are a common example. Instead of laying the piece on the infeed table, lower the forward end of the work onto the outfeed table. Do this very carefully, as the piece will span the knives, and they will take a "bite" from the work with a tendency to kick back unless the piece is firmly held. Now push the work forward as in ordinary jointing.
Maintenance Disconnect machine from power source before doing any maintenance. The table and fence surfaces must be kept clean and free of rust for best results. Some users prefer a paste wax coating. Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week; this will fill casting pores and form a moisture barrier. This method provides a table top that is slick and allows rust rings to be easily wiped from the surface.
IMPORTANT: If the bearings need replacement, this should be done by qualified service personnel. The bearings are press fitted and must be removed with an arbor press. To re-install cutterhead, reverse the above procedure. Before re-installing, make sure the machine's curved seats of the base casting are free of dirt, dust or grease, to help ensure a tight fit. Table Removal 1. Disconnect jointer from power source. 2. Remove fence assembly except for the support casting. 3. Remove cutter guard. 4.
Troubleshooting – Operating Problems Trouble Probable Cause Remedy Finished stock is concave on back end. Knife is higher than outfeed table. Raise outfeed table until it aligns with tip of knife. See page 16. Finished stock is concave on front end. Outfeed table is higher than knife. Lower outfeed table until it aligns with tip of knife. See page 16. Stock has slight bevel after edge jointing. Fence not perpendicular to table. Square up fence with table. Cutting against the grain.
Troubleshooting – Mechanical and Electrical Problems Trouble Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Probable Cause Remedy No incoming power. Verify unit is connected to power, onbutton is pushed in completely, and stop-button is disengaged. Overload automatic reset has not reset. When jointer overloads on the circuit breaker built into the motor starter, it takes time for the machine to cool down before restart.
Trouble Probable Cause Remedy Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Motor failure. If electric motor is suspect, have it tested by qualified service personnel. Repair or replace as needed. Electrical leads are attached incorrectly. Double check to confirm all electrical connections are correct. Refer to appropriate wiring diagrams on pages 36 through 38 to make any needed corrections. Loose electrical connections. Inspect all motor leads for tightness.
