Be sure keyed washer is directly under the spindle nut and the spindle nut is tight.
Feed the workpiece against the rotation of the cutter.
Do not use awkward hand positions.
Keep fingers away from the revolving cutter. Use fixtures when necessary.
Use the overhead guard when the adjustable fence is not in place.
• KEEP GUARDS IN PLACE and in working order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of checking to see that keys and
adjusting wrenches are removed from the machine before turning it on.
• KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.
• DON’T USE IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations,
or expose them to rain. Keep work area well lighted.
• KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area.

from the power source!
Failure to comply may result in serious
injury!
Check the drive belt to insure that the pulleys
are accurately aligned. If alignment is required,
loosen the setscrew (A, Fig. 5) in the motor
pulley and reposition the pulley on the motor
shaft.
Speed Change
The JWS-25CS shaper may be operated at
8,000 RPM (lower pulleys) or 10,000 RPM
(upper pulleys). To change the spindle speed,
loosen the lock handle (B, Fig. 5) and pivot the
motor assembly toward the spindle. Reposition
the belt to the desired speed and tension the
belt.
Squaring the Fence
Periodically the wood fence will have to be

parallel to each other. To correct, do the
following:
1. Check the two ratcheting handles (A, Fig. 6)
holding the fence assembly to the table and
make sure they are tight.
2. Check the four countersink flat head screws
(B, Fig. 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, Fig. 6) and
turn the fence adjustment knobs (D, Fig. 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.

screws.
3. Hold down guides can be adjusted by
loosening knob (D, Fig. 7).
4. Hold in guides can be adjusted by loosening
hex cap screw (E, Fig. 7).
5. Guide supports can be adjusted by
loosening hex cap screw (F, Fig. 7).
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 replace 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.
10
Table Ring Removal and Installation
Disconnect the machine from power source,
unplug!
The rings should easily lift out of the table
insert. The table insert has three setscrews that
can raise and lower the insert. The insert
should be slightly lower than the table. Keep
the rings and insert clean to prevent them from
sticking. If the rings are difficult to remove from
the insert:
1. Remove any collet or spindle assembly in
the spindle.
2. Lower the spindle assembly.
3. Place a scrap of piece of wood between the
ring to be removed and the spindle.
4. Raise the spindle until the ring lifts out.
5. Clean rings and insert thoroughly.
Operation
Spindle Control
To raise or lower spindle:
1.Loosen spindle lock handwheel found on
the left side of the cabinet.
2.Raise or lower spindle to desired height by
turning handwheel found on the front side
of the cabinet. There is an indicator scale
found by the handwheel, which will aid with
raising and lowering measurements.
3.Tighten spindle lock handwheel.
Using the Fence as a Guide
Shaping with the fence is the safest and most
satisfactory method of working. This method
should always be used when work permits.
Almostall-straightworkcanbeusedwiththe
fence.
1. For most work, where a portion of the edge
of the work is not touched by the cutter,
both the front and rear fences are in a
straight line, as shown in figure 8.
11
2. When the shaping operation removes the
entire edge of the work (i.e. jointing or
making a full bead), the shaped edge will
not be supported by the rear fence when
both fences are in line as shown in Figure 9.
In this case, the work piece should be
advanced to the position shown in figure 9
and stopped.
3. The rear fence should be advanced to
contact the work as shown in figure 10. The
rear fence will then be in line with the
cutting circle.
Shaping with Collars and Starting Pin
Follow these rules when shaping with collars
and starting pin for safest operation and best
results:
1. Collars must be smooth and free from all
gum or other substances.
2. The edge of the work must be smooth. Any
irregularity in the surface, which rides
against the collar, will be duplicated on the
shaped surface.
3. A portion of the work's edge must remain
untouched by the cutter so that the collar
will have sufficient bearing surface. See
figure 11 for an example of insufficient
bearing surface.
5. Under no circumstances should a small
workpiece be shaped against the collars
as shown in Figure 13.
12
Collar Positioning
Collars may be positioned above, below, or
between two cutters:
1. When using the collar below the cutter,
figure 14, the progress of the cut can be
observed at all times. A disadvantage of
this method is any accidental lifting of the
work will gouge the wood and ruin the
workpiece.
2. Using the collar above the cutter, figure 15,
offers the advantage of the cut not being
affected by slight variations in the stock's
thickness. However, the cut is not visible
during the operation. Another advantage is
accidental lifting of the work piece will not
gouge the work piece. Simply correct the
mistake by repeating the operation.
3. The collar between cutters method, shown
in figure 16, has both the advantages and
disadvantages of the first two methods.
This method is used primarily where both
edges of the work are to be shaped.
Starting Pin
WARNING
Using the starting pin should only be
attempted by advanced users! If you have
never used this method before, it is
recommended you get training from a
qualified person who is knowledgeable in
starting pin shaping!
Failure to comply may cause serious injury!
The starting pin is placed in one of the threaded
holes in the table:
1. Work should be placed in the first position
using the guide pin as support, as shown in
figure 17. Then swing the work into the
cutter as shown in the second position. The
work will now be supported by the collar and
starting pin.
2. After the cut has been started, the work is
swung free of the starting pin and rides only
against the collar as shown in the third
position in figure 18. Always feed against
the action of the cutter.
