Introduction This manual is provided by Powermatic covering the safe operation and maintenance procedures for a Powermatic Model 719T Tilting Table Hollow Chisel Mortiser. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown. This machine has been designed and constructed to provide consistent, long-term operation if used in accordance to instructions set forth in this manual.
Unpacking Remove mortiser and stand from the shipping cartons. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the mortiser is assembled and running properly. Compare the contents of your container with the following parts list and Figure 1 to make sure all parts are intact. Missing parts, if any, should be reported to your distributor.
Electrical Connections 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.
3. Grounded, cord- connected tools intended for use on a supply circuit having a nominal rating between 150 - 250 volts, inclusive. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch D in Figure 1. The tool has a grounding plug that looks like the plug illustrated in Sketch D in Figure 1. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool.
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 6: 1. Place the wooden table (A) in position on the slide (B). Figure 6 2.
Installing Chisel and Bit Referring to Figure8: 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.
Operating Controls Start/Stop Switch Referring to Figure 10: The Start/Stop Switch is located to the left of the motor on the side of the mortiser. To turn the mortiser on press the green START (A) button. To stop the mortiser, push the red STOP (B) button. Figure 10 On-Off Switch Padlock The push button switch of the Mortiser will accept a safety padlock (not included).
Adjustments 90 Chisel to Worktable Calibration Referring to Figure 12: 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 14: 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 16: 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.
Chisel Sharpen the chisel with a mortise chisel cutter with the correct size pilot. (Pilot size will differ depending on the size of your chisel). Two or three turns of the cutter in a carpenter's brace chuck should be enough to sharpen the chisel, as shown in Figure 21. Use a small, triangular, smooth file to relieve the inner corners of the chisel (Figure 22). Remove any burrs from the outside of the chisel with a fine oilstone. Lubrication All of the ball bearings are packed with grease at the factory.
