Assembly Do not connect the machine to power source until completely assembled. Read and understand the entire manual. Securing Machine to Stand The mortiser should be secured to the stand with four M8 x 45 hex cap screws and M8 lock washers (provided) using the holes in the base. Make sure there is enough room on each side of the mortiser for the size stock you plan to use. Wooden Table Referring to Figure 1: 1. Place the wooden table (A) in position on the slide (B). Figure 1 2.
Installing Chisel and Bit Referring to Figure 3: 1. Loosen the lock screw. 2. Insert the chisel bushing into the head with the hole facing forward to line up with the lock screw. Screw in the lock screw just enough so the screw extends into the hole of the bushing, holding it in place. 3. Push the chisel up through the bushing, bringing it to rest against the shoulder of the bushing. Then lower the chisel approximately 1/16" to 3/16", depending on the type of wood being worked.
Electrical Power Connection Do not machine operate this in damp locations. A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle, which will accept the machine’s plug.
Adjustments 90° Chisel to Worktable Calibration Referring to Figure 7: Place a square (E) so it rests against the worktable (B) and chisel (A). If the chisel to table angle is 90°, no calibration is necessary. If calibration is required: 1. Loosen the bolt (C) that allows the tilting base to pivot. The tilting base is heavy. If raised, take extra precaution not to let it drop on hands or fingers. Injury can result. 2. Adjust the adjustment screws (F) until the chisel to table angle is 90°.
6. Reinstall the chisel bushing (F) and secure it loosely with the lock screw (E). 7. Reinstall the chisel and bit (refer to the Installing Chisel and Bit section). Depth Stop Rod Adjustment Referring to Figure 9: A A depth stop rod (A) is provided to limit the depth of the chisel. To adjust: 1. Loosen lock lever (B) and lower the depth stop rod (A) until it comes to rest on top of the column stop (C). 2.
Chisel Parallel to Workpiece Referring to Figure 11: The chisel can be adjusted parallel to the workpiece as follows: 1. With the left handwheel (A), move the table back far enough to insert the workpiece (B) between the chisel (D) and fence. 2. Loosen the lock screw (C). This will allow the chisel to rotate. 3. Bring the table forward with the handwheel (A) until the workpiece (B) rests against the back surface of the chisel (D), but do not force. Further adjust the chisel by hand if needed. 4.
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. To prevent breakout at the back of the workpiece when cutting through mortises, use a piece of scrap material under the workpiece as support.
three turns of the cutter in a carpenter's brace chuck should be enough to sharpen the chisel, as shown in Figure 16. Use a small, triangular, smooth file to relieve the inner corners of the chisel (Figure 17). Remove any burrs from the outside of the chisel with a fine oilstone. Lubrication Figure 17 All of the ball bearings are packed with grease at the factory. They require no further lubrication. Periodically grease the gears, racks, and table pivot points with a #2 tube grease.
