Assembly and Installation
Tools needed for assembly:
5mm hex wrench
12mm and 14mm open end wrenches
Remove the clear plastic from around the feeder
and stand.
Exposed metal surfaces have been given a
protectiv e coating at the fact ory. This should be
removed wit h a soft cloth moistened with a good
commercial solvent, such as kerosene or
mineral spirits. Do not use acet one, gasoli ne, or
lacquer thinner for this purpose. Do not get
solvents near pl asti c or rubb er par ts, and d o not
use an abrasive pad because it may scratch
metal surfaces.
The Stock Feeder should be mounted to an
auxiliary machine in a well-lit area. Leave
enough space around the work area for l oading
and off-loadi ng stoc k and gener al maintenance.
The stock feeder and the
auxiliary machine to which you are mounting
it should both be disconnected from power
during insta llation.
1. Determine the mounting location for the
stand. Keep in mind t he overall l engt h of the
horizontal arm on the stand ( 27-1/2” ) so that
there will be enough adjustment when the
Stock Feeder is mounted.
IMPORTANT: Locate the stand so that you
will not drill through any ribs or supports
beneath the tabl e surface.
2. Use the provided boring template to find t he
centerline spacing for the holes in the
feeder’s base. Cl ean the mounting surface,
then remove the backing from the boring
template and stick the template carefully
into place on the mounti ng surface.
NOTE: The sam e template can be found on
page 25.
3. Center punch and drill four 8.5 millimeter
diameter holes in the surface, then tap the
holes with M10 x P 1.5 threads. Alter natively,
if you plan to secur e the stand wit h hex nuts
from below the mounting surface, drill
clearance holes of 7/16” diameter without
tapping.
4. Peel off the bori ng template and discard.
5. Loosen the lock handle and remove the
base from the stand assembly, shown in
Figure 1.
Figure 1

6. Place the base ov er the hole patt ern. Align
the four hol es of the base with the hol es in
the mounting surface. Make sure the lock
handle is positioned in a convenient place
before tightening the base to the m ounting
surface.
7. Insert four M10 screws (not provided)
through the holes of the base and into the
holes on the mounting surface. See Figure
2. Tighten screws securely .
8. The stand assembly can be oriented with
either of the col umns in horiz ontal or verti cal
position. It is recommended, however, that
the longer lead screw be placed in the
horizontal position, as shown in Figure 3;
this will allow maximum adjustment for the
stock feeder across the surface of the
workpiece. Slide the vertical column down
into the base and tighten the lock handle
(Figure 3).
9. Attach a handle (Figure 4) to each elevati ng
handle, by screwing the threads of the
handle into the hole on the elevating handle.
10. The handle (F igure 4) should be a djusted so
that it can move freely. Loosen the hex nut
with a 14mm (9/16”) wrench, and turn the
socket head cap screw with a 5mm hex
wrench until the handl e is just loose enough
to turn freely. Then tighten the hex nut
against the el ev ating handle.
Figure 2
Figure 3
11. Rest the Stock Feeder on the mounting
surface, as shown in Figure 5. Lower the
horizontal arm by rotating the top hand
wheel until t he arm is at a conv eni ent height
for mounti ng the Stock F eeder. (See “Basic
Feeder/Stand Movements” for detailed
explanati on of stand m ov em ents.)
12. Make sure t he hex cap screw (A, F igure 5)
is loosened on the sleeve of the Stock
Feeder. Use a 14mm wrench.
13. Slide the arm cone of the Stock F eeder onto
the horizontal arm as far as it will go, then
tighten the hex c ap screw (A, Figure 5).

Grounding Instructions
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
This Stock Feeder must be grounded. In the
event of a m alfuncti on or breakdown, grounding
provides a path of least resistance for electric
current to reduce t he risk of electric shock. This
tool is equipped wit h an electric cord having an
equipment-grounding conductor and a
grounding plug similar to the one shown in
Figure 6. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordanc e wit h al l loc al codes and
ordinances.
Do not modify the pl ug provided. If it will not fit
the outlet, hav e the proper outlet install ed by a
qualified elec trician.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor, with insulation
having an outer surface that is green with or
without yellow stripes, is the equipmentgrounding conduct or. If repai r or replac ement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool i s properly grounded. Us e only
three wire extensi on c or ds that have three-prong
grounding plugs and three- pole recept acles that
accept the tool ’s pl ug.
Repair or replace a damaged or worn cord
immediately.
115 Volt Operation
Figure 6
As received fr om the factory, your Stock Feeder
is ready to run at 115 volt operation. It is
intended for use on a circuit that has an outlet
and a plug that looks similar to the one
illustrated in Figure 6.
A temporary adapter, which looks like the
adapter as illustr ated in Figure 7, may be used
to connect t his plug to a two-pole recept acle, as
shown in Figure 7, if a properly grounded outl et
is not available. The temporary adapter should
only be used until a properly grounded outlet
can be installed by a qualified electrician. This
adapter is not applicable in Canada.
Figure 7
11
The green colored rigid ear, lug, or tab,
extending fr om the adapter, must be connected
to a permanent ground such as a properly
grounded outlet box, as shown in Figure 7.
Make sure the voltage of your power supply
matches the specif ications on the m otor plate of
the machine.
Extens ion Cords
If an ext ension c ord i s necessary m ak e sure t he
cord rating i s suitable for the am perage listed on
the machine's motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.

Speed Selection
The PF3-JR has f our speeds: 13, 26, 33 and 62
feet per mi nute (or 4, 8, 10 and 19 meter s per
minute, respectively). Achieving these four
speeds is dependent upon the choice and
proper positi on of t he gear s.
Unplug the stock f eeder fro m
power source before ch ang ing gears.

1. Unscrew the knob (Figure 11) and pull off
the back cov er to expose the gear system,
shown in Figure 12.
2. Remove hex nuts and flat washers (A,
Figure 12) with a 14mm wrench.
3. Figure 13 shows the relationship of gear
position t o c r eate each of the four speeds. A
similiar chart is affixed to the inside of the
back cover on the Stoc k Feeder .
4. Install new gear configuration, making sure
the notch in each gear slides into the
keyway of the shaft. Push the gear as far as
it will go onto the shaft .

Operating Controls
The control switch (Figure 14) turns the motor
on, and also determines its direction – forward
or reverse.
If a jam should occur while
feeding a w orkpiece, DO NOT turn the sto ck
feeder to reverse w hi le th e auxi liary mach in e
is still running in forward direction.
If a workpiece becomes jammed, turn off both
the auxiliary machine and the stock feeder.
Raise the feeder in order t o clear t he workpi ece.
Then reset the feeder height and begin t he feed
over again.
Figure 14
Operation
IMPORTANT: Before attempting operation of
this stock f eeder in c onjunction wit h an auxi liary
machine, you shoul d be thoroughly f amiliar with
the operating and safety instructions that were
included with the auxiliary machine.
Keep hands away from
rollers during operation. Failure to comply
may cause injury.
General Operating Instructions
1. Make sure all l ock handles are tight bef ore
operating the St oc k Feeder.
2. The Stock Feeder should be used in
conjunction with a fence on your auxiliary
machine.
3. The rollers must gri p the offcut, as well as
the part of the workpi ec e still being fed.
4. On some machines, such as a shaper, the
stock feeder can be mounted so that the
rollers exert pressure from the top; or
mounted edgewise so that the rollers exert
pressure from the side, or mounted at an
intermediate angle for beveled workpiec es.
5. The feed rollers have a spring suspension
with approximately 12mm lift, which will
exert the necessary pressure against the
workpiece. This pressure increases
automatic ally with feed r esistance, so that a
workpiece of varying thickness can be fed
through the stock feeder without
adjustments.
14
6. When used in normal horizontal position,
the stock feeder should be adjusted for
height so that the distance between the
table and the feed rollers is approximately
1/8” to 3/16” (3 to 5mm) less than the
thickness of the workpi ec e. See Figure 15.
Although the stock feeder
when properly used will greatly reduce the
chance of wo rkpiece kickb ack, t here i s still a
potential for kickback. Never stand directly
in the path of the workpiece as it passes
under the Stock Feed er rollers.
When Used with a Shaper
1. The gap between the fences for the cutter
should be as small as possible.
2. To ensure that the workpiece is held firmly
against the f ence, set the stock f eeder at a
slight angl e toward the f ence i n the dir ecti on
of feed. In other words, the outfeed roller
should be approxim at ely 3/16” (5mm) cl oser
to the fence than the infeed roller. See
Figure 16.
Figure 15
3. When the Stock Feeder is in edgewise
position, it must be inclined slightly t owards
the work table in the direction of feed, to
ensure the workpi ece remains forced down
against the table. In other words, the
outfeed roll er should be a pprox im ately 3/16”
closer to the work table than the infeed
roller. S ee Figure 17.
4. When the Stock Feeder is in the edgewise
position, or angled for a beveled workpiece,
the axis of the cutter should be between the
outfeed roller and the center roller. See
Figure 17. The center roller should NOT be
directed toward the opening between the
fences, but should act directly against the
fence.
5. When mounting the Stock Feeder in
edgewise posi tion, keep in mi nd the spring
tension of t he roller s. The distance bet ween
the shaper fence and t he f eed roller s should
be approximately 1/8” to 3/16” (3 to 5mm)
less than the thickness of the workpiece
(refer to Figure 15) .
6. Shaping hardwood with the Stock Feeder
may increase the fricti on between workpiece
and table. Keep t he work tabl e rust-free and
smooth, by using paste wax or other
necessary means.

When Used with a Table Saw
1. Position the Stock Feeder so that the axis of
the saw blade lines up between the center
roller and infeed roller. See Fi gure 18. This
will allow the Stock Feeder to grip t he offcut
of the workpiece as it leaves the blade.
2. Rotate the Stock Feeder so that the
direction of feed is angled sli ghtly toward the
fence by approx im ately 3/16” (5mm) ; that i s,
the outfeed roll er shoul d be sli ghtly cl oser to
the fence t han the infeed roll er. See Figure
18.
When Used with a Jointer
1. Mount the stock f eeder on a jointer so that
all rollers are over the outfeed table, as
shown in Figure 19.
2. The infeed roller should be approximately
3/16” away from the lip of t he outfeed table
at the cutter ar ea. See Figure 19.
3. Rotate the Stock Feeder so that the
direction of feed is angled sli ghtly toward the
fence by approx im ately 3/16” (5mm) ; that i s,
the outfeed roll er shoul d be sli ghtly cl oser to
the fence t han the infeed roll er. See Figure
19.

Roller Removal/Replacement
If more space is needed between rollers, for
example when f eeding a curved workpi ece, the
center roller can be removed from the Stock
Feeder. To remove the roller, loosen and
remove the t wo socket head ca p scre ws (Fi gure
20) with a 5mm hex wrench and pull the roller
off the shaft.
Maintenance
Before performing any
maintenance on the Stock Feeder,
disconnect its plug from the electrical
supply. Also disconnect the auxiliary
machine from the el ect rical supply. Failure t o
comply may cause seriou s injury.
If the power cord is worn, cut, or damaged in
any way, have it repl ac ed immediately.
The rubber rollers should be kept clean of
grease, sawdust and other debris. Use a soft
cloth with soap and water to wipe down the
rollers. DO NOT use a solvent on the rubber
rollers.
Figure 20
16
The mating parts of the arm cone and swivel
cone should be kept clean. See Figure 21.
When disassembli ng any of the cones from t he
stock feeder, wipe off both mating parts with a
clean rag before re-assembling. NOTE: These
cones are subject t o high tor ques and it m ay be
necessary to periodically re-tighten the lock
handles until the cone surfaces become
securely seated.
Lubrication
Gearbox
The Stock Feeder i s shipped with oi l install ed in
the gearbox. Occasionally check the oil level
and add oil if nec essary. The oil level shoul d be
approxim ately 1-1/ 2” deep; that is, about 1” from
the rim of the hole. Completely drain and refill
the oil every 1,000 working hours, or every 6
months, wit h a good quality gear oil.
Figure 21
To change the oil:
1. Loosen t he screw (A, Fi gure 5) which holds
the feeder body t o the horiz ontal arm.
2. Carefully remove the feeder body from the
horizontal arm.
3. Unscrew and rem ov e the oil cap (i dentified
in Figure 22) and turn the feeder body
upside down to completely drain the oil.
(NOTE: Always dispose of used oil
properly.)
4. Turn feeder body right side up, and pour
new oil into the fill hole, until it is about 1”
from the rim.
5. Re-install the oil cap (Figure 22).
Rollers
Each of the three rollers has a grease fitting
(Figure 23) located in the hub center. Use a
grease gun to insert a good quality, all-purpose
grease into these fittings every 200 working
hours, or every 30 days.
Figure 22
Figure 23
17
Chains
Lubricate t he drive chai ns (Figure 24) with good
quality all-purpose grease every 3 months, or
more frequently if needed.
Lead Screw s
Occasionall y apply a light coat of gr ease to the
lead screw of the vertical column, and to the
lead screw of the hori z ontal arm. See Figure 25.
