Spindle Gib Adjustment; Featherboard Hold-Downs - Powermatic PM2500 Series Operating Instructions And Parts Manual

Spindle Gib Adjustment

Referring to Figure 12:
The spindle housing gib on your machine is
factory adjusted and initially should not require
readjust-ment. After a period of use the gib may
wear and become loose, introducing play and
potentially causing the spindle (B) to vibrate. This
requires adjustment.
To adjust:
1. With a 12mm wrench, loosen jam nuts that
secure the gib setscrews in four places (A).
2. With a 4mm hex wrench, tighten each
setscrew 1/8(3.175mm) or less turn starting
with the lowest one,
uppermost one,
setscrews.
If this is not enough to remove the play,
repeat this step until the play is removed.
Note: If the gibs are too tight the front handwheel
that controls the spindle height will be difficult to
turn.
When adjustment is complete:
3. Hold the set-screws in position with the 4mm
hex wrench to maintain the setting while
tightening the jam nuts with the 12mm
wrench.

Featherboard Hold-downs

Referring to Figure 13:
The PM2500 Shaper comes equipped with two
featherboard hold-downs (A, B) mounted on the
infeed and outfeed fences.
1. Loosen lock handles (C) and locking handles
(D).
2. Slide the hold-down guides to the desired
position along the fence and tighten the lock
handles (C).
3. Place the workpiece (E) on the table against
the fence and under the hold-down guide (A).
4. Adjust the featherboard stay to put moderate
pressure on the workpiece, then tighten the
