Installing Bushing, Chisel and Auger

1.The mortiser should be disconnected from power source.

2.Open the chuck access cover (A, Figure 3).

3.Insert a bushing (B, Figure 3) into the hole with the bushing’s hole facing the front toward the set screw (C, Figure 3).

NOTE: The Mortiser is shipped with the 5/8” bushing pre-installed.)

4.Tighten the set screw (C, Figure 3) with a 4mm hex wrench just enough to hold bushing in place.

5.Place the chisel (D, Figure 3) and auger (E, Figure 3) beneath the bushing and allow the auger to rest upon the table while pushing the chisel up through the bushing.

6.The cutting portion of the auger must clear the chisel by about 1/16” to 3/16”, depending upon the type of wood to be worked. Place a “spacer” of 1/8” to 3/16” diameter (a hex wrench works well) between bushing and chisel, and push chisel up until it contacts the spacer.

7. Tighten the set screw (C, Figure 3) to hold the chisel in place, and remove spacer.

Figure 3

8. Push the auger up through the chisel opening and into the chuck as far as it will go. Tighten the auger in the chuck using the chuck key.

9. Loosen the set screw (C, Figure 3) and push the chisel all the way up until it contacts the bushing. This should provide the proper distance so that the cutting portion of the auger clears the chisel. Tighten the set screw (C, Figure 3).

NOTE: Set the slot in the side of the chisel to the left or right, if the cut is to be done laterally; and front or back if the cut is to be done front to back. The chisel slot should always be positioned so chips are being released into the already-cut part of the workpiece.

10. Close the chuck access cover (A, Figure 3) before operating.

Grounding Instructions
