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
ngers 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, pre­vent chip accumulation, and keep fi re-fi ghting equip- ment nearby.
FOR ALL TOOLS
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.
THIS SAW SHOULD BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRI­CAL 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 rat­ing. Replace or repair a damaged or worn cord im­mediately.
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 connect­ed 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.
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, mas­ter 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 jew­elry to get caught in moving parts. Rubber-soled foot­wear 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.
3
DON’T OVER REACH. Keep proper footing and bal­ance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow in­structions for lubricating and changing accessories.
The work area should be neat, well lighted, properly ventilated and free of pedestrian or vehicle traffi c. Am- ple room is needed for stock handling and storage, the fl oors must be free of slipping or tripping hazards as many machines have exposed tooling that can be fallen on.
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. Con­sult the owner’s manual for recommended accessories. The use of improper accessories may be hazardous.
NEVER STAND ON A TOOL. Serious injury can oc­cur 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 prop­erly 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 necessar­ily refl ect the views and policies of OSHA however it is presented for your consideration in maintaining work­place safety.
From
“Machine Guarding -
Assessment of Need”
HEW publication No. (OSHA) 75-173
SUMMARY:
The previous information discussed specifi c machines and their inherent characteristics and hazards. All ma­chines, 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 dis­carded.
These items, though they are not specifi c machine guard needs, are equally important.
It is also interesting to note that operators observed and questioned by the survey representatives and em­ployed on some woodworking and metalworking equip­ment are often new hires with little or no experience with machine operation. This is substantiated by the nding 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 sim­ple; nevertheless, operators should be carefully trained and enthusiastically motivated to perform safely.
A fi nal observation found through fi eld surveys has to do with the size of the company versus the number of unguarded machines (see Field Survey Supple­ment, 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 investiga­tion of specifi c machines to identify inherent hazards, establishes a defi nite need for machine guarding. The fact that a hazard exists and a worker performs in prox­imity 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 benefi t to the employee to be able to manufacture goods without occupational injuries.

Operation & Maintenance
READ CAREFULLY
The MODEL 58B METAL CUTTING BAND SAW is de­signed for effi cient performance. With proper care, it will give you many years of dependable service. READ
THIS MANUAL CAREFULLY BEFORE OPERATING YOUR NEW SAW.
After fi nal 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 fi le a Proof of Loss Claim with the carrier. Be sure motor specifi cations 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, op­erate 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 fl oor. Keep blade guide as close to the work as possible.
PLACING BLADE ON SAW
9. Briefl y 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 fi xed vise jaw assist in the quick relocation of the fi xed 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 ADJUST­MENT
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.
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. Re­place 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.

DASH POT
MAINTENANCE
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 fl ow of fl uid being bypassed through an orifi ce 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 pro­cedure 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 mo­tor. Should the motor stop for other than normal rea­sons, 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 unusu­ally fast, use slower speed. Always keep the blade in proper tension.
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 be­cause 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, ad­just 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 fol­lows:
1. Loosen blade tension until the blade is slack by turning the “T” handle CCW.
2. Raise the frame into the vertical position. See Dia­gram.
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 fl ange of the idler wheel and not on the drive wheel, make the following adjust­ment:
1. Loosen the 2 cap screws, 22E and 22F, at the mo­tor 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 ange of the wheel.
CAUTION: Too much pitch will wear the wheel
anges and roll over the back of the blade! This problem can usually be determined by the noise of the blade rubbing against the fl ange. 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 adjust­ment is reached.

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, fi lled 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
Marfak Grade “O” Grease, or equivalent, is used in the gear case. Other parts of the saw may be lubri­cated 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, fi brous grease.
3. Wheel ball bearings are sealed and permanently lubricated.
4. For proper motor lubrication, follow the motor man­ufacturer’s instructions.
1. Check the blade fi t 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.
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 mate­rial 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 ap­plied to the blade.
5. Reduce feeding pressure for the fi rst two or three cuts with a new blade.
6. Keep the adjustable blade guide as close as pos­sible to the material being cut.
7. Keep blade brushes in contact with the blade teeth at all times.
