Practice is required in this operation. Beginners are advised to make trial cuts with scrap material. Fig. 23 Fig. 24 15 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. In that event, the table is lowered an amount equal to about half the depth of the rabbet for the first pass, then lowered again to proper depth to complete the cut. Removing and Replacing Knives WARNING Disconnect the machine from the power source before making any adjustment or repair! All knife lock bolts must be firmly tightened or risk ejection of the knife(s) and lock bar from the cutterhead! Failure to comply may cause serious injury! 1. Disconnect machine from the power source. 2. Remove blade guard by loosening lock screw (A, Fig. 26) and lifting up on blade guard. Caution: blades are sharp! Use great care when hands are around blade area! 3. Loosen the five lock screws (Fig. 27). Note: Loosen screws by turning in a clockwise direc- Fig. 25 Fig. 26 Fig. 27 tion as viewed from the infeed table. Carefully remove the knife (A, Fig. 28), and the lock bar with screws (B, Fig. 28). Repeat for the other two blades. 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. 16 Fig. 28 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. 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. Gib Adjustment After a period of use, the gibs may become loose and need adjusting: 1. Loosen three lock nuts (A, Fig. 29) and gib lock screw (B, Fig. 29) 2. Tighten each set screw 1/4 turn starting at the bottom and working up. If a 1/4 turn does not remove all play, take another 1/4 turn. Repeat a 1/4 turn at a time for all three set screws until play is removed. 3. Tighten lock screw (B, Fig. 29) and lock nuts (A, Fig. 29). 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. Occasionally, apply a few drops of light machine oil to the gibs. This permits the tables to slide freely. 3. The cutterhead ball bearings are lifetime lubricated and need no further care. Blade Care WARNING Blades are extremely sharp! Use caution when cleaning or changing. Failure to comply may cause serious injury! When gum and pitch collect on the blades, carefully remove with a strong solvent. Failure to remove gum and pitch build-up may result in excessive friction and overheating. When blades become dull, touch up blades. See “Sharpening the Knives” on page 18. Fig. 29 17 Sharpening the Knives WARNING Blades are extremely sharp! Use caution when handling. Failure to comply may cause serious injury! 1. Disconnect the machine from the power source. 2. Remove the fence, blade guard and belt cover. 3. To protect the infeed table from scratches, partially cover the sharpening stone with paper. (Fig. 30) 4. Lay the stone on the infeed table. 5. Lower the infeed table and turn the cutterhead by turning the cutterhead pulley. The infeed table height is set properly when the stone’s surface is flush with the knife bevel. 6. Keep the cutterhead from rotating by grasping the cutterhead pulley while sliding the stone back and forth across the table. 7. Take the same amount of passes for all three blades. When the blades have been sharpened and 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. It is recommended to keep a second set of blades on hand so that they may be installed while the first set is being professionally sharpened. Cutterhead Removal WARNING Blades in the cutterhead are sharp! Use extreme caution when handling the removal of the cutterhead. Failure to comply may cause serious injury! The entire cutterhead assembly may be removed for cleaning or for bearing and blade replacement. Some woodworkers keep a spare cutterhead with replacement blades should the original cutterhead have to be repaired. To remove the cutterhead (including bearings, studs, and housing) from the base casting: 1. Disconnect the machine from the power source. 2. Remove the fence assembly, cutterhead guard, and belt guard. 3. Remo...
