Warning 1. Read and understand the entire owner’s manual before attempting assembly or operation. 2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury. 3. Replace the warning labels if they become obscured or removed. 4. This jointer is designed and intended for use by properly trained and experienced personnel only.
21. Make your workshop child proof with padlocks, master switches or by removing starter keys. 22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 23. Maintain a balanced stance at all times so that you do not fall or lean against the knives or other moving parts. Do not overreach or use excessive force to perform any machine operation. 24. Use the right tool at the correct speed and feed rate.

Setup and Assembly Contents of Shipping Cartons Note: Unit shipped in two cartons.
Do not use gasoline, paint thinner, mineral spirits, etc. These may damage painted surfaces. Cutterhead knives are dangerously sharp! Use extreme caution when cleaning. 4. Apply a thin layer of paste wax to the bright surfaces of the fence and tables to prevent rust. Installing Bed to Stand 1. Use an assistant or hoist mechanism to place bed assembly on top of stand. Be sure identification label on the bed faces the same direction as the label on the stand (Fig. 1). Figure 1 2.
Installing Handwheels 1. Remove protective tape from shaft, and remove screw and washer. 2. Press handwheel (A, Fig. 4) onto shaft, aligning the keyway with the key. If necessary, use a hammer with a block of wood to tap the handwheel completely onto the shaft. 3. Re-install screw and washer (B, Fig. 4). 4. Mount handle handwheel. (C, Fig. 4) onto Figure 4 Assembling Knife-Setting Gauge (JWJ-8CS only) Place the two bases (A, Fig. 5) onto each end of the bar (B, Fig. 5). Snap the four Erings (C, Fig.
Installing Cutterhead Guard The cutterhead guard has a spring tension mechanism which must be properly tensioned when installing the cutterhead guard on the machine. To install the cutterhead guard: 1. Insert a small hex wrench, or similar object, into the pin on the guard tension mechanism (Figure 8-1). 2. Twist the hex wrench and pin clockwise, as shown in Figure 8-2, and hold them there. Figure 8-1 3. Lower the shaft of the guard into the hole on the jointer’s rabbeting ledge. See Figure 8-3.
Installing Dust Chute Attach the dust chute (Fig. 10) to the stand with four screws and four flat washers, through the pre-tapped holes in the stand. 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. Figure 9 Model JWJ-8CS: Remove the cover of the switch box (A, Fig.
Adjustments Recommended Extension Cord Gauges (AWG) Extension Cord Length in Feet * Amps 90° Fence Adjustment Note: whenever making an adjustment to the fence, lift the fence up slightly after releasing the lock handle to avoid scratching the table. 1. Set infeed table to the same height as the outfeed table. 2. Move the fence by releasing lock handle (A, Fig. 14) and pushing the fence assembly until it overlaps the tables. 3. Adjust the fence to a 90° angle by releasing lock handle (B, Fig.
Leveling Outfeed Table to Cutterhead Knives Machine should be disconnected from power source at this time! Cutterhead blades are extremely sharp! Use caution when hands are near the cutterhead! For most jointing operations, the surface of the outfeed table must be level with the knife tips of the cutterhead at their highest point of revolution. The knife tips must project equally from the cutterhead. The outfeed table and cutterhead are adjusted at the factory and should not require adjustment.
7. If blade is higher or lower at one point, slightly loosen five screws (A, Fig. 19) by turning clockwise as viewed from the infeed table. 8. Place the knife setting gauge (B, Fig. 19) on the cutterhead over the blade. Continue loosening the five screws until the springs push the knife up into contact with the gauge. Alternately tighten the five screws to hold each blade in place. 9. Repeat this process with blades two and three.
4. Before assembly, clean all parts thoroughly and clear cutterhead knife slots of any dust or debris. 5. Insert knife into the cutterhead channel making sure it faces the proper direction. 6. Insert lock bar and screws and tighten to hold in place. Blades are set at the proper height when the top of the blade is 1/16" above the cutterhead. 7. Repeat for other two blades. 8.
Infeed Table Depth Stop Referring to Figure 26a: The infeed table travel limiter located on the back of the table sets the upper and lower range for the infeed table height adjustment and should not require any adjustments. The infeed table depth stop (A) limits the depth of a cut (set by adjusting the infeed table handwheel) to a maximum depth of 1/8”. For normal operations, the depth of cut should never exceed 1/8", except for rabbeting operations. Figure 26a If a rabbeting operation is desired: 1.
infeed table and the major flat surface of the workpiece against the fence (Fig. 28). Planing cuts are similar. The major surface of the workpiece is placed on the table with the narrow edge of the workpiece against the fence (Fig. 29). For jointing and planing cuts pressure is directed three ways; into the fence to ensure a square cut, forward to advance the stock, and downward to avoid chatter and vibration.
Bevel Cut To cut a bevel, lock the fence at the desired angle and run the material through, pressing the work firmly against the fence and tables (Fig. 31). Several passes may be necessary for the desired result. Taper Cut Taper cuts require the removal of the cutterhead guard. Use extreme caution when making taper cuts and replace the guard immediately after completion! Failure to comply may cause serious injury! Figure 31 One of the most useful jointer operations is cutting an edge to a taper.
7. Take the same amount of passes for all three blades. Maintenance When the blades have been sharpened, if they still are not cutting efficiently, trying to touch up the blades further will only cause the formation of a second beveled edge. When this starts to happen, it is time to replace blades with another set. Lubrication 1. Use a good grade of light grease on the steel adjusting screws located in the raising and lowering mechanisms of the work tables. 2.
7. Before replacing the cutterhead back into the casting, thoroughly clean the “saddle” and the bearing housings of saw dust and grease so that they seat properly. 8. To re-install the cutterhead, reverse the above steps. Troubleshooting Trouble Probable Cause Remedy Finished stock is concave on the end. Knife tip is higher than outfeed table. Raise outfeed table so it is level with knife tip. Back side of finished stock is thicker than the front side. Outfeed table is higher than knife tip.
