Connecting pressurized air to the lathe allows use of the air blow gun and the vacuum chuck.

See Figures 12 and 13.

1.Connect blow gun hose (A, Figure 12) to the tee connector.

2.Connect your incoming air supply (90 psi) to the quick connect coupler (B).

3.Attach vacuum adaptor (C) to hose (D) and push adaptor into spindle.

7.10Optional accessories

The following items are optional and purchased separately. See your Powermatic dealer for information. If you did not purchase an optional accessory, proceed to section 7.11.

The optional 20-inch bed extension is available in two configurations: Bed Extension only (p/n 6294905) and Bed Extension Kit with elevating and swing-away function (p/n 6294900). The bed extension can be installed to upper or lower sets of holes.

Installing Bed Extension only (p/n 6294905)

Tools required: 10mm hex key

1.Slide tailstock away from edge of bed.

2.Have an assistant hold bed extension flush to end of lathe bed, and insert four screws with washers (provided with bed extension). Snug screws just enough to hold bed extension to lathe bed.

3.Adjust extension bed to lathe bed, aligning the surface and the inside ways as closely as possible.

IMPORTANT: Top surface of bed extension must be flush with surface of lathe bed, and inside ways must be aligned, to allow smooth movement of tailstock across joint.

4.Slide tailstock over joint where beds meet, so that clamping nut is centered over joint (Figure 14). Lock tailstock clamping handle; this will align the beds.

5.Tighten screws in extension bed.

6.Unlock tailstock and slide it back and forth to test smoothness of joint.
