Unpacking Remove mortiser and stand from the shipping cartons. Check for damage and ensure all parts are intact. Any damage should be reported immediately to your distributor and shipping agent. Read the manual thoroughly to familiarize yourself with the correct assembly and maintenance procedures and proper safety precautions.
Assembly Do not connect the machine power source until 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.
4. Tighten the lock screw to hold the chisel in place. 5. Push the bit up through the chisel opening as far as it will go. Lock the drill bit in place with the chuck key. 6. Loosen the lock screw and push the chisel up against the bushing, then tighten the lock screw.

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.
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 depth stop rod (A) is provided to limit the depth of the chisel.
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.
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"...
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.
