9.3 Speed Change
Refer to Figure 5.
The JWS-25CS shaper may be operated at 8,000
RPM (lower pulleys) or 10,000 RPM (upper
pulleys).
To change spindle speed:
1. Loosen the lock handle (B, Figure 5).
2. Pivot the motor assembly toward the spindle.
3. Reposition the belt to the desired speed.
4. Pivot the motor assembly back to tension the
belt. Tighten the lock handle (B).
9.4 Squaring the Fence
Refer to Figure 6.
Periodically the wood fence will have to be squared
with the mounting surface and adjusted parallel to
each other. To correct, do the following:
1. Check the two ratcheting handles (A, Figure 6)
holding the fence assembly to the table and
make sure they are tight.
2. Check the four countersink flat head screws
(B, Figure 6) that secure the wooden fences
and make sure they are tight.
3. Take a 2x4 with a jointed edge and clamp it to
the shaper table making sure the jointed edge
is absolutely on line with the miter groove and
close to the fence as shown in Figure 6.
4. Loosen the two lock handles (C, Figure 6) and
turn the fence adjustment knobs (D, Figure 6)
to move both fences against the jointed edge
of the 2x4. After this adjustment the fences
should make flush contact with the jointed
edge and square with the table.
Note: Periodically the wooden fences may
require resurfacing in order to remain parallel
and square with the table.

9.5 Fence Adjustments
Refer to Figure 7.
1. Adjust fences by loosening ratcheting handle
(A, Figure 7), turning knob (B) to adjust fence
in or out, and tightening ratcheting handle.
2. Adjust spindle guard height by loosening two
screws (C), sliding guard up or down to
desired height, and then tightening screws.

9.6 Changing Cutters
Disconnect the machine from power source,
unplug!
Each size spindle is supplied with a safety lock nut
with left-hand threads located above the spindle
nut. To mount or change cutters, first remove the
safety lock nut. Remove the spindle nut by placing
one wrench on the spindle nut and another wrench
on the flats on top of the spindle. Always install
the safety lock nut before operating shaper.
Tool changing must be done with the utmost care
keeping in mind the following points.
1. Cutters, collars and spacers mounted on the
spindle shaft must have a perfect fit with no
room for movement or play between parts.
2. Holes and counterbores of cutters, collars and
spacers must be perfectly shaped without rust,
dings, nicks or other flaws.
3. Clean all cutters, collars and spacers before
installing them on the spindle.
4. Always mount the cutter as low as possible on
the spindle.
5. Make sure all parts on the spindle are locked
in position before starting the shaper.
