SAFETY INSTRUCTIONS
Know your machine,
its safe and proper use!
DISCONNECT POWER before adjusting or servicing
the saw or changing a blade.
STAY CLEAR of all moving parts. Keep hands and
fingers away form the saw blade.
WHEN MOVING SAW, with hinged frame (saw head),
secure the head in its down position.
WHEN CUTTING MAGNESIUM, take special precau-
tions. Use a sharp saw blade, make only dry cuts, pre-
vent chip accumulation, and keep fire-fighting equip-
ment nearby.
THIS SAW SHOULD BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATOR FROM ELECTRI-
CAL SHOCK.
CORD CONNECTED TOOLS. If the saw is equipped
with an approved 3-conductor cord and a 3-prong
grounding type plug, it should only be connected to
a properly equipped and grounded receptacle. The
green conductor in the cord is the grounding wire.
Never connect the green wire to a live terminal.
Use only a 3-wire extension cord having a 3-pronged
receptacle, a 3-pronged plug and ample amperage rat-
ing. Replace or repair a damaged or worn cord im-
mediately.
PERMANENTLY CONNECTED TOOLS. The saw
should be connected to a grounded, metal-enclosed
wiring system or an equipment-grounding conductor
should be run with the circuit conductors and connect-
ed to the saw’s grounding terminal or lead.
To reset the manual starter after a power interruption,
return the switch to OFF and press the RESET button
before restarting.
KEEP GUARD IN PLACE and in working order.
REMOVE ADJUSTING KEYS AND WRENCHES.
Form a habit. Check to see that all keys and wrenches
are removed from the tool before turning the tool on.
KEEP WORK AREA CLEAN. Cluttered areas and
benched invite accidents.
AVOID DANGEROUS ENVIRONMENT. Do not use
power tools in damp or wet locations. Keep your work
area well lighted.
KEEP CHILDREN AWAY. All visitors should be kept a
safe distance from work area.
MAKE WORKSHOP KID-PROOF with padlocks, mas-
ter switches, or by removing starter keys form tools.
DON’T FORCE TOOL. It will do the job better and
safer at the rate for which it is designed
USE RIGHT TOOL. Don’t use a tool a or attachment
to do a job for which it was not designed.
WEAR PROPER APPAREL. No loose clothing or jew-
elry to get caught in moving parts. Rubber-soled foot-
wear is recommended for best footing.
USE SAFETY GLASSES. Also use face or dust mask
if operation is dusty.
SECURE WORK. Use clamps or a vise to hold work.
Provide adequate support to prevent injury from falling
work pieces.
FOR ALL TOOLS

DON’T OVER REACH. Keep proper footing and bal-
ance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for best and safest performance. Follow in-
structions for lubricating and changing accessories.
DISCONNECT TOOLS before servicing or when
changing accessories such as blades, bits, cutters, etc.
AVOID ACCIDENTAL STARTING. Make sure the
switch is in OFF position before connecting power
tools.
USE ONLY RECOMMENDED ACCESSORIES. Con-
sulttheowner’smanualforrecommendedaccessories.
The use of improper accessories may be hazardous.
NEVER STAND ON A TOOL. Serious injury can oc-
cur if the tool is tipped or the cutting tool is accidentally
contacted.
CHECK DAMAGED PARTS. Before further use of the
tool, a guard, or other part that is damaged, should be
carefully checked to ensure that it will operate prop-
erly and performed its intended function. Check for
alignment of moving parts, breakage, mounting and
any other condition that may affect the tool’s proper
operation. Any guard or part that is damaged should
be properly repaired or replaced.
This excerpt from a survey report does not necessar-
ily reflect the views and policies of OSHA however it is
presented for your consideration in maintaining work-
place safety.
From
“Machine Guarding -
Assessment of Need”
HEW publication No. (OSHA) 75-173
SUMMARY:
The previous information discussed specific machines
and their inherent characteristics and hazards. All ma-
chines, however, require proper power installation and
maintenance. High-speed, rotating cutting tools must
be properly sharpened and well balanced to eliminate
vibration. Saw blades must be properly sharpened
and set to eliminate binding and ensure clean cuts.
Any cutting tool that is cracked or chipped must be dis-
carded.
The work area should be neat, well lighted, properly
ventilated and free of pedestrian or vehicle traffic. Am-
ple room is needed for stock handling and storage,
the floors must be free of slipping or tripping hazards
as many machines have exposed tooling that can be
fallen on.
These items, though they are not specific machine
guard needs, are equally important.
It is also interesting to note that operators observed
and questioned by the survey representatives and em-
ployed on some woodworking and metalworking equip-
ment are often new hires with little or no experience
with machine operation. This is substantiated by the
finding that proper training programs are almost absent
from industry (Field Supplement, page 8) and by the
fact that the highest percentage of accidents occurs
at a young age (see Field Survey Supplement, page
8). The best example of this is with operators of saws
where the operation seems self-explanatory through
observation. Perhaps the operation is basically sim-
ple; nevertheless, operators should be carefully trained
and enthusiastically motivated to perform safely.
A final observation found through field surveys has to
do with the size of the company versus the number
of unguarded machines (see Field Survey Supple-
ment, page 2). The smaller the company in number
of employees, the larger the percentage of unguarded
machines observed. This illustrates a further need for
machine guards.
The age of the operator, the size of the company, and
the lack of training programs, along with the investiga-
tion of specific machines to identify inherent hazards,
establishes a definite need for machine guarding. The
fact that a hazard exists and a worker performs in prox-
imity to that hazard will undoubtedly result in an injury.
Because of this, the use of machine guards to divorce
the operator from the hazard to the highest possible
degree is not only desirable but needed. It is the moral
responsibility of the employer and expected benefit to
the employee to be able to manufacture goods without
occupational injuries.

Operation & Maintenance
READ CAREFULLY
The MODEL 58B METAL CUTTING BAND SAW is de-
signed for efficient performance. With proper care, it
will give you many years of dependable service. READ
THIS MANUAL CAREFULLY BEFORE OPERATING
YOUR NEW SAW.
After final assembly, each saw is inspected and
tested. No adjustment should be needed.
This manual has been prepared to assist you in
the operation and maintenance of your new saw. If
you desire additional information or assistance, please
contact your dealer’s service representative.
INSTALLATION
Uncrate and check all parts. Report any damage
to your carrier and file a Proof of Loss Claim with the
carrier.
Be sure motor specifications correspond with your
power source.
Place the saw so that each leg is carrying its share
of the load. The 58B Saw can be operated horizontally
and vertically. For vertical operation. place frame in
upright position, attach the vertical work table and, op-
erate switch manually.
OPERATION
Do not apply too much feed rate. Start cut carefully
and the new blade will last much longer. Make sure all
four legs are in solid contact with the floor. Keep blade
guide as close to the work as possible.
PLACING BLADE ON SAW
1a. DRY CUTTING MACHINE. Release from safety
latch bar and swing frame into vertical position.
1b. MACHINE WITH WET CUTTING SYSTEM. Re-
move chip pan, then follow instructions in 1a.
2. Open idler wheel hinged guard.
3. Remove blade guard.
4. Turn blade tension wing screw to lower the idler
wheel and slide block assembly.
5. Uncoil a 1/2” x 93” blade.
6. When facing cut-off side of machine, blade must
travel toward the motor end.
7. Be sure blade teeth point in this direction. If not,
twist blade band inside-out.
8. Install blade as follows:
a. Place blade between guide bearings and brush-
es.
b. Insert blade into slot between frame and guard.
c. Slide blade onto the drive and idler wheels.
d. Turn tension wing screw until blade is taut.
9. Briefly start and stop motor a few times to make
sure blade is riding correctly on band wheels, then
tighten blade to proper operating tension.
10. Replace blade guard.
11. Lower frame for horizontal cutting.
12. Check safety bar. Be sure it is in proper position to
prevent frame from being raised beyond maximum
position when used as a horizontal cutt-off saw.
QUICK ACTION VISE
The sliding vise jaw is equipped with a ratchet dog
arm for quick action and a hand wheel for tightening
work in the vise. Excessive pressure is not required to
hold material securely in the vise.
FIXED JAW VISE
Two pins in the fixed vise jaw assist in the quick
relocation of the fixed vise jaw for 90° cutting. For final
and accurate adjustment, the blade should be squared
with the vise jaw by placing machinist’s square head
lightly against the side of the blade and the squares
blade against the machined face of the vise jaw.
NOTE: These pins must be removed before fixed
vise jaw can be turned. For angle cutting, use the
clamp bolts to hold fixed vise jaw.
Loosen sliding vise jaw and push against fixed jaw
vise jaw, then cap screw tightened, leaving vise jaws
parallel.
MAXIMUM VISE CAPACITY & 45° ANGLE ADJUST-
MENT
1. Remove blade brush assembly from blade guide
arm.
2. Remove the two 5/16” cap screws holding guide
arm to the frame.
3. Move guide arm back to the next two holes. Re-
place cap screws and tighten in place.
4. Remove vise jaw pins in fixed vise.
5. Remove 1/2” cap screw from quadrant.
6. Loosen cap screw in center of vise jaw and slide
vise toward motor end of machine about 2-1/4”.
7. Replace 1/2” cap screw in tapped holes and tighten
lightly.
8. With saw frame in cut-off position, place head of
machinist’s square lightly against slot in bed with
the blade of square against machined face of vise
jaw. Tap lightly with lead hammer until vise jaw is
parallel to blade of square. Tighten cap screws.
Use a protractor for angle adjustment.

6
DASH POT
Wellsaws are equipped with a dash pot (frame
check) to stabilize the downward travel of the saw
frame to protect the saw blade from damage. The
action is hydraulic. The flow of fluid being bypassed
through an orifice controls the downward stroke of the
saw frame.
Fill the dash pot to within 1” of top of the bottom of
cylinder with Cities Service “Amplex 05” Hydraulic Oil
or equivalent.
FRAME WEIGHT ADJUSTMENT
The position of the collar in relation to the spring on
the dash pot acts as the frame weight adjustment.
The proper frame weight is approximately 10 lbs.
and is obtained by positioning the collar 3-3/4” down
from the top edge of the upper cylinder to the top edge
of the collar. For less frame weight, loosen collar and
move downward toward tension spring. Reverse pro-
cedure for more frame weight.
Too much frame weight will cause the blade to cut
crookedly.
SWITCH AND MOTOR
This saw is equipped with a start-stop switch that
automatically shuts off the motor at the completion of a
cut when the wheel guard contacts the switch control
lever to the desired position for proper shut-off.
It is necessary to raise the saw frame clear of the
switch control lever before the saw can be started.
Thermal overload protection is provided in the mo-
tor. Should the motor stop for other than normal rea-
sons, it may be due to overload. After the problem has
been corrected, the motor may be reset by following
the instructions on the motor name plate.
SPEED SELECTION
Saws are equipped with step pulleys that provide
three speeds: 76, 141 and 268 blade feet-per-minute.
Change blade speed by loosening wing screw close to
the motor pivot. Place belt in desired position, tighten
wing screw until belt is snug and lock wing screw with
wing nut.
FAST speed to cut thin-wall metal, tubing, thin
brass or any metal that will not burn teeth.
MEDIUM speed on general cutting such as cold
rolled machine steels or any metals which require a
slow speed on a lathe.
Use beeswax when cutting brass. Brass should
always be cut with a new blade. If teeth wear unusu-
ally fast, use slower speed. Always keep the blade in
proper tension.
MAINTENANCE
BEFORE MAKING ANY ADJUSTMENTS, ALWAYS
TRY A NEW BLADE TO MAKE SURE THE CAUSE
OF THE PROBLEM IS NOT A WORN BLADE.
Blade guides are provided to hold the blade in both
horizontal and vertical alignment.
Accuracy of cut depends on proper adjustment of
the blade bearings. Check their condition for wear or a
tendency to stick. When the blade is moved sideways
or with a twisting action, the movement should stop at
the bearings and not be transferred beyond this point.
An eccentric axle is provided on each blade guide.
By rotating this axle, the bearing is drawn away from
the blade.
WHEEL PITCH ADJUSTMENT
If the blade runs too low on wheels, it may be be-
cause of too much blade tension. Loosen the blade by
turning the “T” handle (10) counterclockwise (CCW).
The blade must be reasonably tight.
If this adjustment does not correct the problem, ad-
just the wheel pitch. Usually, adjusting the idler wheel
will correct the problem. However, if it doesn’t, both
idler and drive wheels will have to be adjusted as fol-
lows:
1. Loosen blade tension until the blade is slack by
turning the “T” handle CCW.
2. Raise the frame into the vertical position. See Dia-
gram.
3. Loosen 2 cap screws 7A and 7B 1/2 turn.. Then
tighten 2 cap screws 7C and 7D 1/2 turn.
4. Tighten blade by turning “T” handle CW. If the
blade then runs in proper position on both wheels,
no further adjustment is necessary.
If the blade runs back to the flange of the idler wheel
and not on the drive wheel, make the following adjust-
ment:
1. Loosen the 2 cap screws, 22E and 22F, at the mo-
tor end of the wheel plate.
2. Tighten the 2 Allen screws, 22G and 22H, about
1/2 turn.
3. Tighten all four cap screws.
4. Start the motor to see if the blade runs back to the
flange of the wheel.
CAUTION: Too much pitch will wear the wheel
flanges and roll over the back of the blade! This
problem can usually be determined by the noise of
the blade rubbing against the flange. To check fur-
ther, place a piece of paper between the blade and the
wheel. Start the saw. The blade should not shear the
paper but just fold it over. If it shears the paper, back
off the adjustment a little at a time until proper adjust-
ment is reached.

7
BLADE BRUSHES
Blade brushes should be cleaned frequently with
kerosene or a good solvent. To take advantage of both
rows of bristles, invert blade brushes and install them
on the opposite side of the blade.
For best results, replace worn, filled or sticky brush-
es. When bolting brushes to the mounting angles, be
sure wire bristles are turned in the same direction that
the blade travels.
BLADE GUIDE ADJUSTMENT
1. Check the blade fit between guide bearings by
grasping the blade between the guide and the band
wheel.
2. Twist blade back and forth.
3. If too much clearance is found, rotate the eccentric
axle (34), page 12, until the bearing (32) is snug
against blade and all clearance has been removed.
4. Check guide bearing (32) with thumb by applying
force against bearing. It should be possible to rotate
the bearing while it is snug against the blade and all
clearance has been removed.
5. When looseness has been corrected, make another
cut. If the cut is not straight, further adjustment must
be made.
6. Place a square on the cut. Determine if the blade is
cutting toward or away from the bed or if it is out of
square with the vise.
7. If the vise is out of square, correct this by squaring
the vise with the slot in the saw bed.
8 If the cut is out of square on the vertical dimension,
correct this by moving the guides either away from
or towards the saw bed. This is accomplished as
follows:
a. Loosen the 2 cap screws (31), which hold the
guide (28) to the guide brackets (23 & 37). Hold
the guide from twisting and tap it in the desired
direction until the blade is square with the saw
bed. To do this:
1. Place a spacer between the frame wheel
guard and the switch box raising the blade
teeth just over the saw bed.
2. Place a machinist’s square on the saw bed
and move it to touch the body of the saw
blade - making sure it does not touch the
blade teeth.
3. Use a feeler gauge, .002” or less, to see that
the lade is square from top to bottom. If
further adjustment is needed, loosen cap
screws on one blade guide and rotate guide
so the feeler gauge will not enter at top or
bottom. Do not move guide sideways. This
may move the blade out of square with the
vise. Tighten cap screws.
LUBRICATION
Correct and adequate lubrication is very important
to achieve maximum service. It is imperative that all
dust and dirt be removed before lubricating.
Marfak Grade “O” Grease, or equivalent, is used
in the gear case. Other parts of the saw may be lubri-
cated as follows:
1. Vise adjusting screw. Use a heavy oil or light
grease.
2. Keep internal ring gear and pinion well lubricated
with a good quality, medium grade, fibrous grease.
3. Wheel ball bearings are sealed and permanently
lubricated.
4. For proper motor lubrication, follow the motor man-
ufacturer’s instructions.
LUBRICATION SUMMARY
GEAR CASE:
Service interval; inspect after 3 years and
annually thereafter.
Lubricant: Mobilgrease XHP220 or
equivalent.
VISE SCREW, RING GEAR, PINION: Inspect monthly
Lubricant: Use Anti-seize on vise screw
Use Extreme Pressure Open Gear Lube on ring
and pinion gears sparingly.
HELPFUL SUGGESTIONS
1. To select proper blade, consider the type of mate-
rial to be cut as well as to its size and shape. The
SELECT-O-CHART is a handy reference guide.
2. Use the correct blade speed and correct pressure
for each type of material cut.
3. Always maintain proper blade tension.
4. Lower saw frame carefully so that the blade will
start cutting before full frame feed pressure is ap-
plied to the blade.
5. Reduce feeding pressure for the first two or three
cuts with a new blade.
6. Keep the adjustable blade guide as close as pos-
sible to the material being cut.
7. Keep blade brushes in contact with the blade teeth
at all times.

For Greater Service and Efficiency
Careful Operation - Blade Consideration
Cutting out of line Too heavy a feed or worn blade Reduce feed rate by adjusting frame
weight or replace blade. Replace worn
guide bearings when they begin to show
excessive wear
Guides in wrong position Set as close to work as possible
Guides out of alignment Follow adjustment instructions
Set worn on one side of blade Keep brushes clean. Avoid teeth rub-
bing in cut by applying enough weight so
that each tooth is cutting a good chip
Starting cut on odd shape where
blade does not contact flat surface Retard feed until blade has a good start
in the material
Stripping teeth Blade teeth too coarse Be sure that two or more blade teeth are
in contact with material being cut
Hard spots on material Rotate stock, if possible. Do not put new
blade in cut at same angle
Breaking Guides out of alignment Follow adjustment instructions.
Blade twisting Adjust guides as close to work as pos-
sible. Be sure material being cut is held
firmly
Lack of blade tension Always keep blade tight
Dash Pot malfunction Check hydraulic fluid level and/or condi-
tion of cup leather
Excessive wear Blade speed too fast. Follow recommended cutting speeds
Blade running off Lack of blade tension Always keep blade tight
wheel
Improper wheel pitch adjustment See instructions for wheel pitch adjust-
ment
Always use a light feed on new blades!
