Buffer Pads, Cutter Height, Mortise Depth | Powermatic DT45 instruction

Buffer Pads

The polyethylene buffer pads (shown in Figure

20)have slots through which they are secured to the fences by screws. These buffer pads at times may need to be re-positioned; for example, if a clamping bar is adjusted for a different thickness of workpiece, the buffer pad may need to be adjusted out of the way to prevent obstructing the clamping bar.

To adjust a buffer pad, loosen the two hex cap screws (Figure 20) with a 13mm wrench. Slide the buffer pad as necessary. Retighten both hex cap screws when finished.

Cutter Height

This adjustment will change the height of the tails on the tenon (male) cut, and how deep the mortise (female) cut goes into the thickness of the workpiece.

1.	Disconnect machine from power source.
2.	Loosen the spindle lock screw (Figure 21)
	by turning it counterclockwise with a 6mm
	hex wrench.
3.	Turn the spindle height adjust screw (Figure
	19) with a 5.5mm hex wrench, either
	clockwise to raise the cutter (decrease the
	cutter depth), or counterclockwise to lower
	the cutter (increase the cutter depth).
4.	Tighten spindle lock screw by turning it	Figure 21
	clockwise.	Figure 21
	clockwise.

Mortise Depth

This adjustment ensures that the side pieces of your drawer will remain flush with the front and back pieces of the drawer. The correct fit will have the sides flush with the front and back of the drawer, without showing any of the mortise cut on the inside of the drawer.

The mortise depth adjust bolt, shown in Figure 19, limits how far forward the cutting unit will go, and thus limits the length of your mortise cut.

1.Disconnect machine from power source.

2.Loosen the hex nut on the mortise depth adjust bolt (Figure 21) by turning the hex nut counterclockwise with a 17mm wrench.

3.To decrease the depth of the mortise (female) cut, turn the bolt clockwise. To increase the depth of the mortise cut, turn the bolt counterclockwise.

4.Re-tighten the hex nut.
