Replacing The Cutters; Quill Slide Adjustment; Changing Speeds; Mitre Gauge Adjustment - Powermatic 27 Maintenance Instructions And Parts List

REPLACING THE CUTTERS
To replace the cutter(s), select the proper rectan-
gular hole in the standard shaper wrench and place
it over the flats on the top of the spindle, Figure
14. Place a hexagonal wrench on the spindle nut,
hold the top of the spindle stationary and tum the
spindle nut counterclockwise. Remove the spindle
nut and the slotted washer. Remove the cutter(s)
vertically and replace with the size of your choice.

QUILL SLIDE ADJUSTMENT
Periodically, due to wear, the quill slide will de-
velop side play. To adjust the slide, loosen the
three gib screw hex nuts, Figure 15, and lightly
tighten the gib screws with an Allen wrench. Lock
the gib nuts down to provide the slight play re-
quired to allow the slide free movement. Read-
just gib screws if the slide is difficult to move.

of parts. To adjust the stops to exact 90 degree
and 45 degree angles, use a combination square
as a gauge along with a screwdriver and
