1. INTRODUCTION
The purpose of this manual is to provide in
structions for the installation, operation and
maintenance of your Model L-9 metal cutting band
saw machine, a comparatively simple but rugged
machine tool.
Any power driven machine tool constitutes a
potential hazard to the operator's safety. The
Model L-9 saw has been designed with safety in
mind, but it is still necessary to observe all the
safety rules employed in the operation of any
machine. We recommend you read the safety
manual included with this manual before you start
up the machine. CAUTION: Some guards have
been removed to show the underlying parts in the
following photos. In actual use, make sure all
guards are in place before operating the machine.
2. INSTALLATION
A. LOCATION. When installing the L-9 saw, it is
important that proper consideration
surroundings and location. It should be in an area
large enough for operator safety. The machine and
the work area should be properly lighted, without
severe reflections or other visibility hazards.
The L-9 saw does not normally require any special
foundations or footings. However, the floor under it
should be adequate to support the machine with its
maximum intended load. The machine should be
level and shimmed so that each foot is resting
firmly on the floor, carrying its proportion of the
load
without
B. ELECTRICAL HOOKUP. All electrical wiring
to the machine must meet all local and national
electrical codes, and should be installed so that it
will not be subject to damage from normal
operation of the machine or related material
handling equipment.
C. CHECK-OUT. Before the initial start-up,
visually inspect the machine to see that all drive
belts are in proper position and that the machine

lubrication. If this does not adequately free up the
cutting head, the machine should be thoroughly
inspected for concealed damage such as bent frame
members or broken cutting head hinge bolts.
Using the switch next to the cutting head descent
valve (Fig. 8), turn on the blade motor. The
machine should start and run quietly and freely. If
it does not, check for damaged pulleys or belts,
bent shafts, etc.

wheel guards on the cutting head. Hold the looped
blade in front of you with the smooth back edge
toward you. Lower the blade into the cutting head
and place it around the wheels (Fig. 2). The teeth on
the lower strand of the blade should be in position
to cut as the blade travels toward the driving
wheel. If the teeth are not pointing in this direction,
remove the blade, turn it
At each blade guide, twist the blade to a vertical
position (teeth down) and insert it up between the
guide rollers (Fig. 3). Turn the blade tensioning

3. OPERATION
A. CUTTING FORCE. When a new blade is in
stalled on the machine, the cutting force should
always be reduced for the first five or six cuts. A
new blade, being sharp, will penetrate the work
much faster and may be damaged by tooth tips
chipping off or teeth stripping if
not reduced. After the “
cutting force may be increased to normal and, as
the blade dulls, the cutting force may be increased
more to maintain cutting speed. Eventually a point
will be reached where either the blade will cut too
slowly, or the force required to make it cut will be
so high that crooked cuts will result, dictating a
new blade.
The cutting force is adjusted by the step cam (Fig.
6) that controls the tension on the counterbalance
spring. Lift the cutting head completely up. Then

use, position the spring rod in the second step down

Normally, a narrow work piece requires a light
cutting force, and a wide work piece requires a
medium to heavy cutting force. Tooth pitch must
also be considered in determining cutting force. A
coarse pitch blade on a narrow work piece will
require much less cutting force that a fine pitch
blade on the same work piece. To familiarize
yourself with the saw blades, tooth pitch, cutting
force and other related factors, read the ac

D. STOCK STOP BAR. If a number of pieces are
to be cut the same length, the stock stop bar may
be used to
work in the machine vise and lower the cutting
head until the blade is just above the work piece.
Position the work piece under the blade for the
the
desired length of cut, and tighten the vise securely.
Loosen the clamp screw in the stop arm casting
(Fig. 9) so that the casting will slide along

piece and tighten the clamp screw, positioning the
stop on the upper edge of the work piece.
This will allow the arm to swing up and away from
the work piece, eliminating jamming of the work
piece between the blade and the stop arm at the
completion of the cut. When setting the stop for
short work pieces, be careful not to adjust the stop
arm so
E. GUIDE ARMS SETTING. Before starting a
cut, adjust the two saw guide arms as close as
possible to the work piece, but be sure to leave
enough room so that the

contact with the work piece at any time), a light,
cutting force should be used, and the cutting head
descent valve should be opened only enough to
allow a slow, even feed through the cut. A thin
section does not present enough area to the saw
blade for normal cutting forces to be used.
Therefore, the cutting head would fall through the
work too rapidly, causing overfeeding and blade
failure. This situation is prevented by slowing the
maximum rate of descent.
G.
COOLANT. If your machine is equipped with a
coolant system, it is

CAUTION: Do not run the coolant pump any
length of time unless it is submerged in coolant. If
you wish to run the machine without
tank, unplug the coolant pump.
For most sawing applications, a weak soluble oil
and
water
becomes too thick or oily, it will result in too much
lubrication and poor blade life. Most materials can
be cut satisfactorily without coolant, but blade life
will be somewhat less and the time per cut will be
somewhat longer because the blade speed must be
reduced to prevent overheating. It may be desirable
to cut some items dry due to their size, shape or
other physical characteristics, or to eliminate other
possible problems which may arise when using
coolant. The only materials on which we do not
recommend using coolant are the “D” series of air
and oil
bronze alloys.
H.
ANGLE CUTTING. To make cuts of various
angles from 90 to 45 degrees, loosen the two bolts
holding the stationary vise jaw to the saw bed. Use
a protractor to position the vise jaw on the bed to
the desired angle. As the angle becomes more
acute, it may be necessary to remove the bolt from

obtain the desired angle. Tighten the bolts securely

The oil level of the hydraulic cylinder should be
maintained within 1/2
piston rod all the way down. This will require
occasional filling with a medium grade of hydraulic
oil. If the oil level falls below the top hose fittings in
the cylinder, the cutting head action will become
spongy and a considerable drop in the head will be
noticed after the head is raised and released onto
the hydraulic cylinder. If this happens, remove the
cylinder cap and fill the cylinder. Replace the cap,
leaving it loose, and work the head up and down 8

does not fall between cycling periods.
B. BLADE WHEEL ALIGNMENT. When the
blade wheels are properly adjusted, the blade will
run with the smooth edge making light contact
with the wheel flanges. If this contact becomes too
heavy, it will wear the wheel flange unduly and
create a noisy scrubbing sound. It also causes an
edgewise strain on the blade at the point of wheel
contact which can cause blade fatigue and
breakage.
Before making any blade wheel pitch adjustments,

5. TROUBLE SHOOTING
Problems will eventually be encountered with any
machine tool, and it is our intent here to help solve
them. The Model L-9 saw is a basically simple
machine, and it is usually not difficult to find the
underlying cause of the problem.
A. CROOKED CUTS. This problem
by many faults which may occur singly or in any
combination. A machine that is perfectly aligned
and properly operated can make unsatisfactory
cuts if the blade being used is defective. For this
reason, if a machine suddenly begins to cut out of
tolerance, we recommend that a new blade be in
stalled as a first attempt to obtain satisfactory
cuts. Always keep the blade guide arms adjusted as
close to the work as practical, as a long blade span
provides less rigidity.
If a new blade is installed and the machine con
tinues to make crooked cuts, consult Section 3-A
and the saw blade manual concerning the proper
cutting force for the material being cut and the
length of blade in contact with the cut.
Crooked cuts are sometimes caused by the blade
being too loose. Consult Section 2-E concerning
blade tension. If the preceding suggestions have
been followed and the machine still does not cut
straight, consult the separate manual on saw
adjustment and carefully check the adjustment and
alignment of the saw blade guides.
B. BLADE STALLS. If the blade stalls during a
cut, first check to determine whether the blade is
slipping on the drive wheel or if the V-belts are
slipping on the pulleys. If the saw
on the drive wheel, the blade is not properly ten
sioned. Consult Section 2-E and properly tension
the saw blade. If the V-belts are slipping on the
pulleys, consult Section 4-F and properly tension
the belts. If nothing is slipping but the motor is
stalled and will not start, allow it to cool, then push
the stop or reset button to reset.
C. BROKEN BLADES. Consult the separate
guide booklet and check to see if the blade guide
rollers are too tight. Sometimes poor blade wheel

B and check for this condition. Another cause of
blade breakage is too much cutting force. Consult
Section 3-A and the Saw Blade Selection and
Application Manual to determine the correct
cutting force for the material being cut.
D. STRIPPED TEETH. The most frequent cause
of stripped blade teeth is incorrect tooth pitch for
the job being performed. Consult the saw blade
manual to determine the proper blade tooth pitch
for the material and size being cut. Sometimes
excessive cutting force will cause teeth to strip.
Consult Section 3-A and the saw blade manual
concerning
possibility is improper blade brush adjustment.
Consult Section 4-H to correct this condition.
E. POOR BLADE LIFE. This problem is usually
caused by a blade speed too fast for the type of
material being cut. Consult Section 3-B
blade manual to determine the proper blade speed.
Cutting scaly material or cutting through or near
torch-cut areas can also reduce blade life.
F. ERRATIC FEED. If the
feed

we suggest you consult Section 4-A concerning
lubrication. This problem may also be caused by
improper blade tooth pitch for the job being per
formed. In this case, consult the Saw Blade
Selection and Application Manual to determine the
correct blade pitch. Another possibility is poor
blade brush adjustment. Consult Section 4-H of
this manual.
