SAFETY INSTRUCTIONS

Know your machine, its safe and proper use!

DISCONNECT POWER before adjusting or servicing the saw or changing a blade.

FOR ALL TOOLS

STAY CLEAR of all moving parts. Keep hands and fi ngers away form the saw blade.

KEEP GUARD IN PLACE and in working order.

WHEN MOVING SAW, with hinged frame (saw head), secure the head in its down position.

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.

WHEN CUTTING MAGNESIUM, take special precautions. Use a sharp saw blade, make only dry cuts, prevent chip accumulation, and keep fi re-fi ghting equipment nearby.

KEEP WORK AREA CLEAN. Cluttered areas and benched invite accidents.

THIS SAW SHOULD BE GROUNDED WHILE IN USE

TO PROTECT THE OPERATOR FROM ELECTRI-

CAL SHOCK.

AVOID DANGEROUS ENVIRONMENT. Do not use power tools in damp or wet locations. Keep your work area well lighted.

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.

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.

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.

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.

To reset the manual starter after a power interruption, return the switch to OFF and press the RESET button before restarting.

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. Ample 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.

These items, though they are not specifi c machine guard needs, are equally important.

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.

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 fi 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.

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.

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.

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.

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.

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.

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

INSTALLATION

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.

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.

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.

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 brushes.

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.

5

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

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.

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

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:

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.

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.

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.

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 fl ange of the wheel.

CAUTION: Too much pitch will wear the wheel

fl 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 further, 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.

6

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 brushes. 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

LUBRICATION SUMMARY

GEAR CASE:

Service interval; inspect after 3 years and

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.

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.

Trouble Shooting

For Greater Service and Effi ciency

Careful Operation - Blade Consideration

Cutting out of line Too heavy a feed or worn blade

Guides in wrong position

Guides out of alignment

Set worn on one side of blade

Reduce feed rate by adjusting frame weight or replace blade. Replace worn guide bearings when they begin to show excessive wear

Set as close to work as possible

Follow adjustment instructions

Keep brushes clean. Avoid teeth rubbing in cut by applying enough weight so that each tooth is cutting a good chip

Stripping teeth

Blade teeth too coarse

Breaking

Starting cut on odd shape where

blade does not contact fl at surface

Hard spots on material

Guides out of alignment

Blade twisting

Retard feed until blade has a good start in the material

Be sure that two or more blade teeth are in contact with material being cut

Rotate stock, if possible. Do not put new blade in cut at same angle

Follow adjustment instructions.

Adjust guides as close to work as possible. Be sure material being cut is held fi rmly

Always keep blade tight

Lack of blade tension

Excessive wear

Blade speed too fast.

Blade running off Lack of blade tension

wheel

Improper wheel pitch adjustment

tion of cup leather

Follow recommended cutting speeds

Always keep blade tight

See instructions for wheel pitch adjustment

Always use a light feed on new blades!
