Lower Work Support To use the lower work support, remove the table (see “Table Removal and Storage”). Loosen the locking handle (Figure 16) and slide the lower work support into position. Re-tighten the handle securely. Re-setting the Head The head can be adjusted in order to achieve the maximum workpiece height. 1. Place a block of wood for support between the head and fence (Figure 17). Lower the head until it rests upon the block. 2. Loosen only slightly the hex nut (A, Figure 17). 3. Pull down the handle (B, Figure 17) until the cylinder (C, Figure 17) bottoms out. 4. Tighten the hex nut (A, Figure 17). Gib Adjustment The tightness of the gibs has been set at the factory and should not require adjustment. As parts wear through long-term use, or “play” develops in the gib, adjustments can be made as follows. NOTE: Gib tightness should be just enough to allow smooth movement without binding. Gib for Vertical Movement 1. Slightly loosen the three hex cap screws (D, Figure 17) which hold the gib. 2. Turn the gib screws (E, Figure 17) until any play is removed. 3. Re-tighten the hex cap screws (D, Figure 17) securely. Figure 15 Figure 16 Figure 17 14 Gib for Front-to-Back Movement 1. Remove the two screws on the pleated dust cover (F, Figure 18) and move the dust cover out of the way. 2. Loosen the three hex nuts (G, Figure 18) with a 10mm wrench. 3. Turn the three set screws (H, Figure 18) with a 3mm hex wrench, until play is eliminated on the gib (J, Figure 18). 4. Re-tighten the three hex nuts (G, Figure 18) NOTE: Hold the set screws so they do not turn during the tightening process. 5. Re-install the pleated dust cover (F, Figure 18) before operating. Gib for Lateral Movement 1. Remove the two screws on the pleated dust cover (F, Figure 19) and move the dust cover out of the away. 2. Loosen the three hex nuts (K, Figure 19) with a 10mm wrench. 3. Turn the three set screws (L, Figure 19) until all play is eliminated on the gib (M, Figure 19). 4. Re-tighten the three hex nuts (K, Figure 19). NOTE: Hold the set screws so they do not turn during the tightening process. 5. Re-install the pleated dust cover (F, Figure 19) before operating. Tool Storage The cabinet shelf contains a perforated cushion for the accessories, as shown in Figure 20. Operating Controls The magnetic starter with control buttons is mounted to the motor. Press the “start” button to begin rotation of the auger. Press the “stop” button to stop rotation of the auger. The auger will quickly coast to a stop after the “stop” button is pressed. The magnetic starter is a valuable safety feature of the Mortiser. Should electrical power suddenly be cut off while the mortiser is being operated, the magnetic starter will prevent the machine from immediately re-starting when power is restored. To re-start the Mortiser you must press the “on” button. Figure 18 Figure 19 Figure 20 15 Operation General operating procedure: 1. Position workpiece on table and secure with clamp. 2. Set depth stop. 3. For lateral cuts, adjust positive stops according to length of cut. 4. Position head front-to-back and laterally for the first cut. If making a lateral cut, make sure the Y-axis locking handle is tightened. 5. Turn on the machine and feed the chisel and bit steadily into the workpiece. IMPORTANT: The rate of feed must be fast enough to prevent burning at the tip of the bit, but not so fast as to cause the machine to slow or stall. The different rates of feed for different woods must be learned by experience. 6. After the first cut, the head is moved using one of the handles for each successive cut. The direction of movement must allow the chips to clear freely. Move the workpiece so that the slot in the chisel is releasing chips into the already-cut part of the workpiece (Figure 21). Do not have the chisel slot against the blind end of the mortise, as the chips will not be able to clear the chisel. This can cause overheating and possible breakage of chisel or bit. When cutting deep mortises, make the cut in several stages of approximately 1” each, to allow chips to clear. When cutting through- mortises, to prevent breakout at the back of the workpiece and damage to the work table, use a piece of scrap material under the workpiece as support. Maintenance Before doing maintenance on the mortiser, disconnect it from the electrical supply by pulling out the plug or switching off the main switch. Failure to comply may cause serious injury. The Mortiser requires only minor maintenance, such as cleaning and lubrication and routine adjustment and sharpening of the chisel and bit. Wipe down the Mortiser after each use and, as necessary, use light applications of oil or grease to lubricate linkages, moving parts, etc. If the power cord is worn, cut, or damaged in any way, have it replaced immediately.
