Features and Terminology - 60C and 60HH Jointers Figure 1 7
Unpacking Open shipping cartons and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Jointer is assembled and running properly. Compare the contents of your cartons with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.
Assembly Exposed metal surfaces, such as the table and fence, have been given a protective coating at the factory. This coating should be removed with a soft cloth and solvent (such as mineral spirits) once the machine has been assembled. Do not use an abrasive pad as it may scratch the exposed surfaces. NOTE: If any procedure described herein needs further clarification, consult the assembly drawings at the back of this manual.
The guard is spring tensioned. When mounted, it must have enough tension to completely cover the cutterhead, and press firmly against the fence. Test the tension by swinging the guard away from the fence and then releasing it. The guard should snap back to the fence. NOTE: The guard must operate freely and must not drag on the rabbeting ledge or infeed table. If dragging occurs, check that the locking handle (Figure 6) is tight. If guard still drags, the guard assembly may need adjustment or replacement.
Installing Belt Guard and Door Refer to Figure 9. Mount the belt guard over the shaft as shown, and install the knob to secure it in place. Set the lip of the door over the bottom edge of the stand opening. Rotate the door knob to hold the door to the stand. NOTE: When the jointer is being operated, the two M6 pan head screws (KK) and M6 flat washers (LL) should be installed to fully secure the door. At this moment, however, leave these screws off until the switch has been installed.
Installing Fence Handwheel Refer to Figure 12. Install the handwheel (H) onto the shaft, and tighten the set screw with a 3mm hex wrench. Knife Gauge Assembly (model 60C only) Refer to Figure 13. The knife gauge assembly consists of a bar, two end pieces and two e-clips. Slide the end pieces onto the ends of the bar as shown, and use a pliers to push the e-clips into the grooves on the bar.
If the jointer is to be hard-wired to a panel, make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the jointer will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired. Grounding Instructions This machine must be grounded.
Three-Phase Test Run On the three-phase unit, after wiring has been completed, you should check that the incoming leads have been connected properly: 1. Connect machine to power source and press the start button. Make sure cutterhead is clear of all obstructions! (See page 21 for more detailed instructions on the switch.) 2. The cutterhead should rotate clockwise as viewed from the front of the machine. If the cutterhead rotation is incorrect, press the stop button and disconnect machine from power. 3.
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. Do not grab the cutterhead itself to rotate it. 3. Remove the old knives by loosening gib screws with an 8mm wrench, and allowing the springs to push the knife upward. Remove knife and gib. 4. Clean the gib and the knife slot. Sandwich new knife and gib together and drop into slot. Make sure the knife is oriented properly as shown in Figure 16.
10. The tightening process should continue at least two more times, each time tightening the screws more on all three knives. On the third time, they should all be firmly tightened. Before starting the jointer, make sure all gib screws are firmly tightened. A loose knife thrown from the cutterhead can cause severe or fatal injury. 11. After replacing knives, the outfeed table must be checked and adjusted so that it is level with the high point of the knives. See “Setting Outfeed Table” on pages 18-19.
Leveling Tables Refer to Figure 20. The tables have been leveled with each other from the factory, but this should be confirmed by the user, and checked periodically, by placing a steel straight edge across both tables. If tables are not level, this may be the result of loose gibs. Correct as follows: 1. Loosen hex nuts on the gib screws (A) with a 12mm wrench, then loosen the gib screws with a 4mm hex wrench. Loosen the table lock handle (B). Figure 20 2.
Adjusting Depth of Cut Refer to Figure 21. Depth of cut is determined by the height of the infeed table relative to the cutterhead. Setting the infeed table is achieved with both a rapid adjust and a fine adjust. Rapid Adjust: 1. Loosen the lock screw (A) and the locking handle (B). 2. Raise or lower the height adjustment handle (C) until the scale (D) reads just under the correct depth of cut. Figure 21 Fine Adjust: 3.
After the outfeed table has been set at the correct height, it should not be changed except for special operations or after replacing knives. Examples of incorrect settings: If the outfeed table is too high, the finished surface of the workpiece will be tapered (Figure 23).
Fence Stops See Figure 29. Periodically check the 90 degree and 45 degree tilt accuracy of the fence with an angle measuring device, such as an adjustable square or machinist's protractor. If adjustments are necessary, proceed as follows: 90-degree stop: 1. The 90-degree stop is controlled by the screw (E, Figure 29). Figure 28 2. Loosen the locking handle (C) and the hex nut on the screw (F). 3.
Operating Controls Start/Stop Power Indicator Light – The start switch has a power indicator lamp which is on whenever there is power connected to the Jointer, not just when the Jointer is running. Do not assume that no light means there is no power to the machine. If the bulb is bad, there will be no indication. Always check before use. Do not rely that no light means no power to the machine. Always check for power first.
Basic Jointer Operation NOTE: If you are inexperienced at jointing, use scrap pieces of lumber to check settings and get the feel of operations before attempting regular work. This section briefly discusses general rules as well as some of the basic cuts using a jointer, such as surfacing, edging, beveling, skewing, rabbeting and taper cuts. Always use cutterhead guard (except during rabbeting) and keep hands away from cutterhead.
IMPORTANT: When stock is longer than twice the length of the infeed and outfeed tables, an assistant or support table must be used to support the stock. Always use a hold down or push block when surfacing short stock or stock less than 3 inches thick. Jointing Warped Surfaces If the wood to be jointed is dished or warped, take light cuts until the surface is flat.
Skewing (Shear Cutting) When edging or facing burl or birds-eye maple, it is not unusual to deface or mar the surface being finished. This is caused by the cutterhead knives occasionally cutting against the grain. In order to prevent the defacing or marring of this type wood, it is necessary to skew, or angle finish, the material being worked. Refer to Figure 36. 1. Release the fence locking handle (A, Figure 36) and remove the hex nut and washer (B) holding the fence to the fence support.
Rabbeting A rabbet cut requires removal of the cutter guard. Use extreme caution and keep hands clear of cutterhead. Always replace guard immediately after rabbeting operation is completed. Refer to Figure 37. A rabbet is a groove cut along the edge of a board. Never rabbet a piece of wood less than 12" long. Use push blocks to rabbet cut whenever possible. Figure 37 1. Disconnect machine from power source. 2. Set fence for the desired width of the rabbet. 3.
Sharpening Knives (model 60C only) Knives should be kept sharp. This will contribute to better stock finish, longer machine life, and safer operation. A jointer knife hone provides a simple way to sharpen straight knives. Hones are available from many woodworking supply stores. Carefully read any instructions that accompany the hone. Use caution and proceed slowly when sharpening knives. Disconnect jointer from power source, and wear approved eye protection.
9. Lift cutterhead straight up from base. 10. Remove pulley and both bearing housings. IMPORTANT: The bearings are press fitted; if they need replacement, this should be done by qualified service personnel only. 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.
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, on-button 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 Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Probable Cause Remedy Loose electrical connections. Inspect all motor leads for tightness. Look for any signs of electrical arcing which would indicate loose connections or circuit overload. On/off switch failure. If the on/off switch is suspect, you have two options: Have a qualified electrician test the switch for function, or purchase a new on/off switch and establish if that was the problem on changeout.
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 pages 18-19. Finished stock is concave on front end. Outfeed table is higher than knife. Lower outfeed table until it aligns with tip of knife. See pages 18-19. Stock has slight bevel after edge jointing. Fence not perpendicular to table. Square up fence with table. Cutting against the grain.
