INTRODUCTION:
This manual covers the installation, operation and
maintenance instructions necessary for operation of
the bar feed. For information on the sawing
machine or controls, refer to their respective
manuals.
In order to satisfactorily set up and align the BF-14
or BF-20 bar feed with a band saw machine, the
machine itself must first be properly positioned,
leveled and aligned. Consult the manual for your
sawing machine and carefully follow through to be
sure this has been done. There are several machine
and bar feed combinations available, but all are set
up and will operate basically the same.
A. ALIGNMENT AND LEVELING
1. ATTACHMENT. The sawing machine bed is
predrilled to align with the bar feed header. These
holes in the bar feed header are oversize to allow
some adjustment. Start by attaching the leveling
bar on the sawing machine bed
feed header (Fig. I). Now position the bar feed
header on top of the leveling bar and against the
machine bed. Align the holes and turn in the bolts,
but do not tighten.

2. VERTICAL ADJUSTMENT. The height of the
bar
feed may be
the foot pads. These screws are hollow to allow the
bar feed to be bolted to
To align the bar feed vertically, place a long
straight-edge across the sawing machine bed next
to the stationary vise jaw and extending the full
length of the bar feed, as shown in Fig. 1.
With the carriage in the forward position, adjust
the set screws in the leveling bar to raise or lower
the front end of the bar feed as required to bring the
straight-edge slightly above the machine bed (Fig.
1). Do this for both sides of the bar feed, or place a
level on the carriage and adjust both sides alter
nately until the carriage (when adjusted for .000
to .010
” above the saw bed) is parallel to the bed.
Now adjust the back legs up or down until the
straight-edge is parallel with the sawing machine
bed.
Now
readjust the set screws in the leveling bar (if
necessary) to the tolerance shown in Fig. 1, and
again adjust the back legs on the bar feed up or
down to keep the slight clearance of the straight
edge above the machine bed parallel.

It is normally easier to adjust only the rear legs on
the bar feed until the above conditions are
achieved, then turn down the leveling screws on the
center legs to support the load on their section of
the barfeed rails. The carriage, when properly
adjusted, will be parallel to the length of the saw
bed and the .000
with the straight-edge on either side of the bar feed.
If the straight-edge shows a condition similar to
Fig. 2, the results can be crooked cuts as the
carriage comes closer to the sawing machine.
3. HORIZONTAL ADJUSTMENT. First check
the machine vise to assure that it is square with the
machine vise slide slot, as outlined in your sawing
machine manual. When you are sure this vise is
square, place the straight-edge in the vise and
” to .010
” clearance will be met

clamp it. This will effect a position similar
Move the carriage forward and adjust it to center
between the bar feed rails. Clamp the vertical hold
down bolt onto the bar feed carriage so it is just
touching the straight-edge.
Move the carriage to the back reset position (back
by the stock roller). Again, the vertical hold down
bolt should just be touching the straight-edge with
the carriage centered between the rails. If it does
not touch the straight-edge, place shims between
the bar feed header and the machine bed until this
condition is achieved. Then tighten the header
bolts. If an out-of-alignment condition exists (Fig.
4), the sawing machine will cut crooked from side
side.

is properly aligned.
Re-alignment is necessary every time the unit is
moved. Because the bar feed is relatively long,
moving it only a short distance will place it on a
new floor area that may be substantially higher or
lower than the floor the machine was leveled on.
Many times these machines have been moved and
replaced in the same “
without re-alignment, only to have crooked cuts
result.
B. OPERATION
Before attempting to start the automatic feed,
thoroughly familiarize yourself with the proper
operation of the sawing machine controls and read
the safety manual. Refer to the control panel in Fig.
5 for the following operation:
1. MANUAL OPERATION. Any time the saw
blade stop button is pushed, it will stop the saw
blade and will also stop the control circuits. (This
feature is not incorporated on field-installed bar
feeds because of existing circuitry). This, in turn,
will not allow the cutting head to descend.
Therefore, to operate the machine it is first
necessary to turn the manual-automatic selector to
"manual
position. This establishes the proper conditions so
the machine can be operated manually, and the
procedures outlined in the other manuals will
generally apply for setting the head return limit
stops and other standard equipment.
After sawing through a work piece, the cutting
head will return to the upper stop collar and the
saw blade will turn off. To start the next cut it is
only necessary to start the saw blade and open

the same rate of descent.
Using the manually closed valve will allow the
cutting head to bleed down after returning. The
valve must be manually closed to hold the cutting
head up in the returned position.
Both
valves provide the same function, allowing
the cutting head to descend onto the work piece at
the adjusted rate
that the automatically closing valve will close itself
when the cutting head returns.
2. AUTOMATIC OPERATION. Move the stock
feed carriage to the returned position (back by the
stock roller) and engage the feed dog into the rack
by swinging the small arm by the feed dog at the
end of the carriage feed cylinder. Place the work
piece on the carriage and between the saw vise
jaws. Adjust the cutting head saw blade to clear
the work piece by approximately one inch. Position
the work piece for a trim cut and move the clam
ping vise jaw up just to the work piece, but do not
clamp. Leave the vise open enough to allow the
work piece to slide through.
Position the work piece next to the vertical
clamping screw on the bar feed carriage, and this
will align it with the sawing machine vise. Clamp
