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). 2. Line up two holes in top of stand with holes in bed assembly by viewing through access door in stand. 3. Attach bed assembly to stand with two 3/8" lock bolts and lock washers (Fig. 2). Hand tighten only at this time. Fig. 1 4.
Assembling Knife-Setting Gauge 1. Place the two bases (A, Fig. 4) onto each end of the bar (B, Fig. 4). Snap the four E-rings (C, Fig. 4) into the grooves on the bar as shown. Fig. 4 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.
4. Position of the table and straight edge should look like figure 9. Use care when handling the straight edge near the blades so as not to damage them. 45° 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. Loosen lock handle (A, Fig. 7). Move the stop plate (B, Fig. 7) out of the way and position the fence at the 45° angle. Make sure the fence sits against the stop bolt (C, Fig. 7). 2.
5. When the outfeed table and blade number one are the same height, tighten table lock screw. 6. The knives must be parallel with the outfeed table. Bring the straight edge forward to the front of the outfeed table and confirm that blade number one is at the same height at the front of the table as it is at the back of the table. 7. If blade is higher or lower at one point, slightly loosen five screws (A, Fig. 10) by turning clockwise as viewed from the infeed table. Fig. 10 8.
Installing V-Belts 1. Disconnect the machine from the power source, unplug. 2. Remove the lock knob (A, Fig. 14) and belt guard (B, Fig. 14). 3. Place v-belts onto cutterhead pulley grooves and through opening in stand. 4. Pull v-belts down and place onto motor pulley (Fig. 15). If necessary, loosen the mounting screws (A, Fig. 15) and slightly lift motor. Retighten the screws when belt is placed. Fig. 14 5.
Installing Access Cover 1. Install access cover by placing bottom of panel into access in stand and fastening by turning latch (Fig. 17). If the access door latch needs adjustment: 1. Remove the access door from the stand. 2. Loosen the hex lock nut (A, Fig. 17). Rotate the latch a quarter turn clockwise to tighten and counterclockwise to loosen. Fig. 17 3. Tighten the lock nut (A, Fig. 17). 4. Re-install the access door. Installing Dust Chute 1. Attach the dust chute (Fig.
Operation WARNING Keep all guards in place and in adjustment at all times during the cutting procedure! Keep hands away from the cutterhead! Do not pass hands directly over the cutterhead! The use of push sticks and/or handle pads are highly recommended when using the jointer! Failure to comply may cause serious injury! Jointing cuts or edge jointing are made to square an edge of a workpiece.
Jointing Warped Material If the work to be jointed is cupped or warped, take light, repetitive cuts until the surface is flat. Forcing the material flat against the table will still leave a warped piece after the cuts have been made.
Rabbet Cut WARNING Rabbeting requires the removal of the cutterhead guard. Use extreme caution when making rabbeting cuts and replace the guard immediately after completion! Failure to comply may cause serious injury! 1. Adjust the fence so that the distance between the end of the knives and fence is equal to the width of the rabbet (Fig. 25). 2. Lower the infeed table an amount equal to the depth of the rabbet. If the rabbet is quite deep, it may be necessary to cut in two or more passes.
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. When blades become dull, touch up blades. See “Sharpening the Knives” on page 18. 7. Repeat for other two blades. 8. To set the knives to the outfeed table and to the same height in the cutterhead, see section titled “Leveling Outfeed Table to Cutterhead Knives” found on page 10 of this manual.
Sharpening the Knives To remove the cutterhead (including bearings, studs, and housing) from the base casting: WARNING 1. Disconnect the machine from the power source. Blades are extremely sharp! Use caution when handling. Failure to comply may cause serious injury! 2. Remove the fence assembly, cutterhead guard, and belt guard. 1. Disconnect the machine from the power source. 3. Remove the v-belt from the cutterhead pulley. 2. Remove the fence, blade guard and belt cover. 4.
