Tools needed for assembly:
8.5mm drill bit
M10 x 1.5P tap
17mm wrench
Remove the cl ear pl astic from around t he Stock
Feeder and Fence Assembly.
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, gasoline, 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 F eeder should b e m ount ed to a b and
saw table in a well -lit area. Leav e enough space
around the work area f or loadi ng and off -loadi ng
stock and general maintenance.
The Stock Feeder and the
band saw to which you are mounting it
should both be disconnected from power
during installation.
Follow these steps to assemble and install the
Stock Feeder and Fenc e:
Use the diagram in F igure 1 (page 8) to i dentif y
the proper loc ati on for marking the hol e patt erns
on the band sa w table. Do not drill and tap t he
holes yet, only mark them.
Mounting the Fence
1. The fence must be parallel with the blade
for accurate cuts as well as for safety. To
achieve this, mark the location of the near
hole for the Fence based on the di m ensions
in Figure 1, page 8. Drill and tap the near
hole then place the fence over the hole
pattern. I nsert an M10 x 30 hex cap screw
with lock washer into the near hole, as
shown in Figure 2. With a 17mm wrench,
make the screw snug. Do not tighten
completely.
2. Loosen t he handle (A, Fi gure 3) and rotate
the knob (B, F i gure 3) unti l the f ence i s right
up to the blade; that is, the scale on the
fence should be at “0” .
Figure 2
Figure 3

Page 10
3. Tighten the handle (A, Figure 3). If
necessary, m ove the Fence sli ghtly to bring
it parallel with the blade.
4. When satisfied, mark the location of the
second hole using the hole in the Fence
base as your template.
5. Remove the Fence from the tabl e, and drill
and tap the second hole.
6. Place the Fence over the hole pattern again,
and secure the F ence to the tabl e with two
M10 x 30 hex cap scre ws and t wo M1 0 loc k
washers. Tighten firmly.
Mounting the Feeder
1. Screw the handle (Fi gure 4) all t he way into
the threaded hole of t he St oc k Feeder .
NOTE: If the mounting surface is narrow, a
bracket (not provided) must be attached to
support the Stock Feeder. Figure 5 shows an
example.
Figure 4
The Stock Feeder is heavy.
Use a hoist during installation procedures.
Failure to compl y may cause inju ry!
2. Figur e 6 shows the proper met hod of lifting
the Stock Feeder with a hoist. Place one
end of the strap or rope around the motor
mount and the ot her end ar ound the handl e,
as shown.
3. Lift the Stock Feeder carefully into place
over the hole pat tern previously marked on
the band saw table, and verify that the hole
pattern lines up correctly with the holes in
the Stock Feeder base.
4. Remove the Stock Feeder, and drill and tap
the four holes.
5. Secure the Stock Feeder to the table with
four M10 x 30 hex cap screws and f our M 10
lock washers. See Figur e 7.
6. It is important that the serrated roll ers of the
Stock Feeder are properly positioned in
reference to t he blade. Figure 8 shows how
the center of the rollers should be aligned
with the front tips of the blade teeth. The
gearbox top cov er is ali gned wit h the roll er s,
so you can use the top cover’s center for
making this ali gnm ent. S ee Figure 8.

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.
As received from the factory, the PF-BS Stock
Feeder will run on either 230 volt or 460 volt,
depending upon your particular model. Make
sure the voltage of your power supply matc hes
the specifications on the motor plate of the
machine.
You may ei ther connect an appropriat e UL/CSA
listed pl ug or “hard-wire” the mac hine di rectly t o
a control panel. If hard-wired to a panel, make
sure a disconnect is available for the operator.
The Stock Feeder must comply with all local and
national codes after being wired. If it is to be
hard-wired, make sure the fuses have been
removed or the breakers have been tripped in
the circuit to which the Stock Feeder will be
connected. Pl ace a warning placard on t he fuse
holder or circuit breaker to prevent it being
turned on while t he machine is being wired.
Refer to “El ectrical Connect ions” on page 23 f or
connecting the motor leads.
This mac hine m ust be grounded. I n the event of
a malfuncti on or break down, groundi ng prov i des
a path of l east resistance f or elect ric current, to
reduce the ri sk of elect ric shock to the oper ator.
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 conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equi pment-grounding c onduc tor to a
live terminal.
Repair or replace a damaged or worn cord
immediately.

Fence Movement
To move t he fence toward or away from the saw
blade, loosen the l oc k handle (A, Figure 10) and
rotate the knob (B, Fi gur e 10) .
A millimeter scale is inscribed on the edge of the
rack (C, Figure 10).
After adjustment, re-tighten lock handle (A,
Figure 10).
Spring Tension
The amount of tension directed against the
workpiece is controlled by the spring, and is
adjustable. Regulate the tension on the spring
by turning t he hex nut , shown in Fi gure 11. Turn
the hex nut clockwise to increase tension,
counterclockwise to decrease tension.
Arm Positioning
The arm of the Stock Feeder can be pulled
away from the blade and secured there by
pushing up the stop rod (Figure 11) into the hole
in the bracket . NO T E: Make sure the stop rod i s
pushed up as far as it will go i nto t he hole.
To release the arm, pull back slightly on the
handle of the Stock Feeder, and pull the stop
rod downward out of the hole. Carefully allow
the arm to swing back toward the bl ade.
The arm will swing back
toward the b lade with force w hen the spring
is tensioned. Guide the arm back without
letting it hit the saw blad e.
