Introduction This manual is provided by Powermatic covering the safe operation and maintenance procedures for a Model PJ-882 and PJ-882HH Jointer. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown. This machine has been designed and constructed to provide consistent, long-term operation if used in accordance with instructions set forth in this manual.
Contents of the Shipping Container Unpacking 1 1 2 1 1 1 1 1 1 1 2 10 5 Open shipping container 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 container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor.
Installation and Assembly Tools required for assembly Forklift or hoist with straps/slings 14mm (or 9/16”) wrench or socket Cross-point (Phillips) screwdriver 3mm and 5mm hex wrenches (provided) 1. Remove any boards or straps that secure the Jointer to the pallet, and remove protective wrapping. 2. Use a 14mm (or 9/16”) wrench to remove the four lag screws at the base of the stand which helped secure the machine to the pallet. One of these screws is shown in Figure 1.
Installing Switch Arm 1. The switch arm was shipped in horizontal position. Loosen and remove the four socket head cap screws and flat washers on the bracket of the switch arm (Figure 3) with a 5mm hex wrench. Hold on to the switch arm while doing this, to prevent the arm from falling. 2. Place the switch arm in vertical position, as shown in Figure 3, and align the four holes in the bracket with the four holes in the jointer stand. 3.
The cutterhead guard should now have sufficient spring tension. Test it by swinging the guard away from the fence and then releasing it. The guard must always have enough spring tension to cover the unused part of the cutterhead during the cutting operation, and to swing back to contact the fence when the workpiece has cleared the area.
Recommended Gauges (AWG) of Extension Cords 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. Extension Cord Length * Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug. Repair or replace a damaged or worn cord immediately.
Adjustments Drive Belt Tension To check or adjust the drive belt tension: 1. Unscrew the knob (A, Figure 11) and remove the belt guard (B, Figure 11). 2. Remove the rear panel (C, Figure 11) by unscrewing the four flat head screws (D, Figure 11) with a cross-point screwdriver. 3. Proper drive belt tension is achieved when there is a small amount of deflection in the drive belt midway between the pulleys, when using moderate finger pressure (Figure 12). Figure 11 4.
Fence Movement The fence can be moved forward or backward across the width of the table. It also tilts up to 45 degrees forward and backward, and contains positive stops at both these angles, as well as a positive stop at 90 degrees. To slide fence forward or backward: 1. Loosen locking handle (A, Figure 14). 2. Push the entire fence assembly to the desired position, and tighten locking handle (A, Figure 14).
4. Tighten locking handle (B, Figure 16). IMPORTANT: When the tilted operation is finished and the fence is returned to 90°, do not forget to flip the 90° stop block (F, Figure 16) back to its original position. Fence Stops Periodically check the 90° and 45° 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: Setting the 90° Stop 1.
2. Flip the stop block (E, Figure 18) out of the way. 3. Loosen the locking handle (B, Figure 18) and loosen the hex nut on the screw (G, Figure 18). 4. Tilt the fence backward. Set your angle measuring device at 135° and place it on the table and against the fence. 5. If necessary, turn the screw (G, Figure 18), until the fence lies flush against the angle measuring device. 6. Re-tighten the hex nut on the screw (G, Figure 18) and tighten locking handle (B, Figure 18).
Setting Tables Coplanar For optimum performance of the jointer, the infeed and outfeed tables must be coplanar; that is, parallel front-to-back and side-to-side. If they are not parallel in both planes, the finished workpiece may have a slight taper across its width or length. The tables have been properly aligned at the factory. However, they should be doublechecked by the operator in case any misalignment may have occurred during shipping.
follows. 9. Each table has four cam adjustment devices; two in front and two in back. (C, Figure 22 shows one of these). NOTE: On the front of the Jointer, the two outside cams are concealed by the hubs. You must remove the hub to expose the cam adjustment device. Remove the socket head cap screw and flat washer at the center with a 6mm hex wrench, and loosen the setscrews in the hub (Figure 21 shows one of two set screw holes).
Setting Knives at Correct Height and Parallel To Outfeed Table For accurate jointing, the outfeed table surface must be level with the knives (or knife inserts for the helical cutterhead) at the high point of their arc. In addition, on the straight cutterhead, the knives must be parallel with the outfeed table along the entire length of the knives. When you receive the jointer, the knives have been pre-set at the factory.
Figure 27 illustrates the correct setting of outfeed table level with the knives. The workpiece will rest firmly on both tables with no open space under the finished cut. The outfeed table has now been locked at a standard height, level with the arc of the knives. NOTE: After the outfeed table has been set at the correct height, it should not be changed except for special operations or after replacing knives.
14. Slightly loosen the five gib screws (see Figure 31) with an 8mm wrench. (NOTE: The springs below the knife will cause the knife to rise.) 15. Turn the jack screw(s) with a hex wrench; clockwise to lower the setting of the knife in the cutterhead, counterclockwise to raise the setting of the knife. 16. Use the edge of a board to push the knife back down so that it is flush against the jack screws. See Figure 32. Tighten the gib screws only enough to keep the knife in position in the cutterhead.
Outfeed Table Stop Screws The stop screw (B, Figure 33) limits the amount of fall of the outfeed table. The stop screw has been pre-set at the factory, but if future adjustment is ever needed, simply loosen the hex nut (A, Figure 33) and turn the screw (B, Figure 33) as needed with a 14mm wrench. When satisfied, re-tighten the hex nut (A, Figure 33). The screw (C, Figure 33) limits the rise of the outfeed table.
Replacing Knives (Straight Cutterhead Only) Jointer knives are extremely sharp. Use caution and proceed slowly when working with or around the cutterhead. 1. Disconnect jointer 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 the square head gib screws with an 8mm wrench. See Figure 36.
Replacing or Rotating Knife Inserts (Helical Cutterhead Only) Knife inserts are sharp; use caution when working with or around them. The knife inserts on the model PJ-882HH are four-sided. When dull, simply remove each insert, rotate it 90° for a fresh edge, and reinstall it. Use the provided star point screwdriver to remove the knife insert screw. See Figure 37a. It is advisable to rotate all inserts at the same time to maintain consistent cutting.
3. Tighten hex nut (B, Figure 38). 4. Repeat for the other set screws as needed. NOTE: The outfeed table is pre-set at the factory tighter than the infeed table. If you find the outfeed table difficult to move with the lifting handle, loosen the two set screws on the outfeed table, as just described. 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.
Hand Placement At the start of the cut, the left hand holds the workpiece firmly against the infeed table and fence while the right hand pushes the workpiece in a smooth, even motion toward the cutterhead. After the cut is under way, the new surface rests firmly on the outfeed table. The left hand is transferred to the outfeed side and presses down on this part of the workpiece, at the same time maintaining flat contact with the fence.
NOTE: The knives must be extended beyond the cutterhead by 1/32”. (see “Replacing Knives – Straight Cutterhead Only” on page 23 for this procedure). 4. Re-connect power. It is easier and safer to take a series of shallow cuts. Lower the infeed table 1/32” at a time and make successive cuts until the desired depth of rabbet has been obtained. See Figure 42. Jointing Short or Thin Work When jointing short or thin work pieces, use a push block to eliminate all danger to the hands.
1. Release the fence locking handle (A, Figure 46) and remove the two hex nuts and washer (B, Figure 46) holding the fence to the slide bracket. Remove the fence assembly. 2. Remove the key (C, Figure 46) from the fence support. If necessary, use a flat head screwdriver to pry up one end of the key. 3. Replace the fence assembly at the desired angle across the cutterhead. See Figure 47.
Sharpening Standard Knives 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 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.
Troubleshooting – Operating Problems Trouble Probable Cause Remedy Finished stock is concave on back end. Knife or knife insert is higher than outfeed table. Raise outfeed table until it aligns with tip of knife/insert. See page 19. Finished stock is concave on front end. Outfeed table is higher than knife or insert. Lower outfeed table until it aligns with tip of knife/insert. See page 19. Finished stock is concave in the middle. Both tables have too much end fall.
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. See page 25. 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 Miswiring of the unit. Double check to confirm all electrical connections are correct. Refer to appropriate wiring diagrams on pages 45 through 47 to make any needed corrections. On/off switch failure.
