SAFETY

For Machines Mfd. Since 10/22

Additional Hydraulic System Safety

Infection, amputation, or death can result from contact with leaking hydraulic ﬂ uid under high pressure. Additionally, leaking hydraulic ﬂ uid is a serious slip hazard and ﬁ re hazard. To reduce these risks, anyone operating this machine MUST completely heed the hazards and warnings below.

Injection Injuries: Immediately seek medical

attention if injection injury occurs. Leaking hydraulic fluid often has enough pressure to penetrate skin, which can lead to infection, amputation, or death. Hydraulic fluid can enter the skin through small wounds that are barely noticeable. Minimizing the time between injury and removal of the injected material is critical to successful treatment.

Check For Leaks: Never use your hands to check for

hydraulic leaks. Small leaks can be invisible to the naked eye. Use a piece of wood or cardboard to find suspected leaks.

Eye Injuries: Safety glasses may not be sufficient

to protect against pressurized hydraulic fluid. Depressurize hydraulic system before approaching a known leak.

Fluid Contamination: Make sure hydraulic system

maintenance is performed in a clean and dustfree work area. Remove all contaminants from near hydraulic system openings and components prior to maintenance, to prevent debris from entering the hydraulic system. Always use lint-free rags when cleaning components. Contaminated hydraulic fluid may damage the machine and cause hydraulic system failure that can result in serious injury

Do Not Operate with Leaks: Immediately stop

machine and depressurize hydraulic system if a leak is discovered or suspected. Operating hydraulic system with leaks may increase the hazard of the situation and damage the machine.

Component Replacement: Only use high-pressure

hydraulic hose and steel hydraulic fittings with compatible threads when replacing components in the hydraulic system. DO NOT overtighten or use soft metal fittings such as brass or aluminum.

Depressurize for Maintenance: Always

depressurize hydraulic system before

stop machine and disconnect power before relieving hydraulic pressure. Verify hydraulic pressure is at 0 PSI before proceeding with maintenance.

Preventing Leaks: Always support and restrain

hydraulic hoses to minimize friction during operation that could lead to machine damage that may result in serious injury. Regularly inspect and perform maintenance on the hydraulic system. Following a regular schedule will decrease the likelihood of damage to the machine and reduce the risk of associated

This machine must be grounded! In the event of certain types of grounding provides a path of least resistance for electric current electric shock.

This machine is equipped with a power cord that has grounding plug The plug receptacle (outlet) grounded in accordance with all local codes and ordinances.

Improper connection of the equipmentgrounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipmentgrounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with an electrician or qualiﬁ ed service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded.

If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. If you must use one, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle listed in the for the applicable voltage, and meet the following requirements:

Cleaning & Protecting

The unpainted surfaces are coated at the factory with a heavy-duty rust preventative that prevents corrosion during shipment and storage. The beneﬁt of this rust preventative is that it works very well. The downside is that it can be time-consuming to thoroughly remove.

Be patient and careful when cleaning and removing the rust preventative. The time spent doing this will reward you with smooth-sliding parts and a better appreciation for the proper care of the unpainted surfaces.

Although there are many ways to successfully remove the rust preventative, the following process works well in most situations.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (citrus-based degreasers work well and have non-toxic fumes)

• Safety glasses & disposable gloves

Figure 7. Loose inventory.

If you cannot ﬁnd an item on this list, carefully check around/inside the machine and packaging materials. Often, these items get lost in packaging materials while unpacking or they are pre-installed at the factory.

Many cleaning solvents are toxic if inhaled. Minimize risk by using these products in well-ventilated area.

Basic steps for removing rust preventative:

1. Put on safety glasses and disposable gloves.

2. Coat surfaces that have rust preventative

with cleaner/degreaser and let them soak for few minutes.

Wipe off surfaces. If cleaner/degreaser is

effective, rust preventative will wipe off easily.

Note: To clean thick coats of rust

preventative on ﬂat surfaces, like beds or tables, use PLASTIC paint scraper to scrape off most of coating before wiping it off with rag. (Do not use metal scraper or it may scratch surface.)

-14-

Repeat Steps 2–3 as necessary until clean,

then coat all unpainted surfaces with quality metal protectant or light oil to prevent rust.

Operation Tips

The following tips will help you safely and effectively operate your bandsaw, and help you get the maximum life out of your saw blades.

Tips for cutting:

• Use the work stop to quickly and accurately cut multiple pieces of stock to the same length.

• Clamp the workpiece ﬁrmly in the vise jaws to ensure a straight cut through the material.

• Allow the blade to reach full speed before cutting a workpiece. Never start a cut with the blade in contact with the workpiece, and do not start a cut on a sharp edge.

• Chips should be curled and silvery. If the chips are thin and powder-like, increase your downfeed rate.

• Burned chips indicate a need to reduce your blade speed.

Figure 21. Location of disabling functions.

Children or untrained people can be seriously injured by this machine. This risk increases with unsupervised operation. To help prevent unsupervised operation, always disable switch before leaving machine unattended. Make sure to place key in a well-hidden or secure location!

• Wait until the blade has completely stopped before removing the workpiece from the vise. Avoid touching the cut end—it could be very hot!

• Support long pieces so they will not fall when cut. Flag long ends to alert passers-by of the potential danger.

• Adjust the top blade guide as close as possible to the workpiece to minimize sideto-side blade movement.

• Use cutting ﬂuid when possible to increase blade life.

Loosen blade tension when bandsaw is not in use to prolong blade life.

Workpiece Inspection

Before cutting, inspect the material for any of the following conditions and take necessary precautions:

• Small or Thin Workpieces: Small or thin

workpieces may be damaged during cutting—avoid cutting these workpieces if possible. If you must cut a small or thin workpiece, attach it to or clamp it between larger scrap pieces that will both support the workpiece through the cut. Some thin sheet metals will not withstand the force from this bandsaw during cutting instead, use a shear, nibblers, or sheet metal nippers to cut these pieces.

• Unstable Workpieces: Workpieces that

cannot be properly supported or stabilized with the vise should not be cut on this bandsaw. Examples are chains, cables, workpieces with internal or built-in moving or rotating parts, etc.

• Material Hardness: Always factor in the

hardness of the metal before cutting it. Hardened metals will take longer to cut, may require lubrication, and may require a different type of blade in order to efﬁciently cut them.

Selecting Blades

Selecting the right blade for the cut requires a knowledge of various blade characteristics.

Blade Terminology

Figure 22. Bandsaw blade terminology.

A. Kerf: Amount of material removed by blade

during cutting.

B. Tooth Set: Amount each tooth is bent left or

right from blade.

C. Gauge: Thickness of blade.

• Tanks, Cylinders, Containers, Valves, Etc.:

Cutting into containers that are pressurized or contain gases or liquids can cause explosions, ﬁres, caustic burns, or machine damage. Avoid cutting any of these types of containers unless you have veriﬁed that the container is empty and it can be properly supported during a cut.

• Magnesium: Pure magnesium burns easily.

Cutting magnesium with a dull blade can create enough friction to ignite the small magnesium chips. Avoid cutting magnesium if possible.

D. Blade Width: Widest point of blade mea-

sured from tip of tooth to back edge of blade.

E. Tooth Rake: Angle of tooth face from line

perpendicular to length of blade.

F. Gullet Depth: Distance from tooth tip to

bottom of curved area (gullet).

G. Tooth Pitch: Distance between tooth tips.

H. Blade Back: Distance between bottom of

gullet and back edge of blade.

The chart below is a basic starting point for choosing teeth per inch (TPI) for variable pitch blades and standard raker set bi-metal blades/ HSS blades. However, for exact speciﬁcations of bandsaw blades that are correct for your operation, contact the blade manufacturer.

To select correct blade pitch:

1. Measure the material thickness. This

measurement is distance from where each tooth enters workpiece to where it exits workpiece.

Refer to "Material Width/Diameter" row of

blade selection chart in Figure 24, and read across to find workpiece thickness you need to cut.

Refer to "Material Shapes" row and find

shape of material to be cut.

In applicable row, read across to right

and find box where row and column intersect. Listed in the box is minimum TPI recommended for variable tooth pitch blades.

The TPI range is represented by a "/"

between numbers. For example, 3/4 TPI is the same as 3–4 TPI.

Standard or Raker: Equally spaced teeth set at

a "0" rake angle. Recommended for all purpose use.

Variable Pitch (VP): Varying gullet depth and

tooth spacing, a "0" rake angle, excellent chip removing capacity, and smooth cutting.

Blade Breakage

Many conditions may cause a bandsaw blade to break. Some of these conditions are unavoidable and are the natural result of the stresses placed on the bandsaw; other causes of blade breakage are avoidable.

The most common causes of avoidable blade breakage are:

• Faulty alignment or adjustment of the blade guides.

Forcing blade through the workpiece too

•

fast.

Dull or damaged teeth.

•

• Improperly-tensioned blade.

Top blade guide assembly set too high above

•

the workpiece. Adjust the top blade guide assembly as close to workpiece as possible.

Using a blade with a lumpy or improperly

•

finished braze or weld.

Blade Care & Break-In

Blade Care

To prolong blade life, always use a blade with the proper width, set, type, and pitch for each application. Maintain the appropriate downfeed rate and blade speed (refer to the Blade Speed Chart on Page 28), and pay attention to the chip characteristics (refer to the Chip Inspection Chart on Page 28). Keep your blades clean, since dirty or gummed up blades pass through the cutting material with much more resistance than clean blades, causing unnecessary heat.

Blade Break-In

The tips and edges of a new blade are extremely sharp. Cutting at too fast of a feed rate or too slow of a blade speed can fracture these tips and edges, quickly dulling the blade. Properly breaking-in a blade allows these sharp edges to wear without fracturing, thus keeping the blade sharp longer. Below is a typical break-in procedure. For aftermarket blades, refer to the manufacturer's break-in procedure to keep from voiding the warranty.

Leaving the blade tensioned when not in use.

•

• Using the wrong blade pitch (TPI) for the

workpiece thickness. The general rule of thumb is to have no fewer than three teeth in contact with the workpiece when starting a cut and at all times during cutting.

Use the Chip Inspection Chart on Page 28 as a guide to evaluate the chips and ensure that the optimal blade speed and downfeed rate are being used.

To break in new blade:

1. Choose correct speed for blade and material

type.

2. Reduce downfeed rate by half for first 50–

Chip Inspection Chart

The best method for choosing the cutting speed and downfeed rate for a cutting operation is to inspect the chips created by the cut. These chips are indicators of what is commonly referred to as the "chip load." Refer to the chip inspection chart below to evaluate chip characteristics and determine whether to adjust downfeed rate/pressure, blade speed, or both.

OPERATION

Tensioning Blade

Proper blade tension is essential to avoid blade vibration, twist, or slippage on the wheels. A correctly tensioned blade provides long blade life, straight cuts, and efficient cutting.

The three major signs of incorrect blade tension are: 1) The blade stalls in the cut and slips on the wheels, 2) the blade frequently breaks, and 3) the bandsaw does not make straight cuts.

Loosen blade tension when bandsaw is not in use to prolong blade life.

To tension blade:

1. Press HYD ON button to turn hydraulic

pump ON.

Adjust headstock until blade is

approximately 6" above vise table.

Manual & Automatic Controls

The Model SB1122 has two operation modes: automatic and manual. Manual mode includes all of the controls necessary to prepare the machine for a cut, but will not perform the actual cut. Automatic mode will complete the cut without much user intervention through a series of preestablished settings. After a cut is prepared in manual mode, the automatic mode can be used to carry out the operation and achieve subsequent cuts to help speed production.

See the following steps for the controls required for each to accomplish a typical cutting operation.

Preparing a Cut

Manual mode is most useful when setting up a new cutting configuration. This mode allows you to plan your cut before actually cutting, and to test that a new blade has been installed correctly for the operation.

Figure 38. Location of top blade guide components.

The bottom blade guide has a wire brush that makes contact with the blade to help clear away chips and extend blade life (see Figure 39).

Using Cutting Fluid System

Cutting fluid is a mixture of cutting fluid and water. While simple in concept and function, many issues must be taken into account to mix and use the correct cutting fluid. Always follow all product warnings and specifications, and contact the cutting fluid manufacturer for unanswered questions.

Use the information below as a guideline to choose the appropriate cutting fluid. Always refer to the cutting fluid manufacturer for specific application and safety information:

• For cutting low alloy, low carbon, and general-purpose category metals with a bi-metal blade —use a water soluble cutting fluid.

• For cutting stainless steels, high carbon, and high alloy metals, brass, copper and mild steels, use "Neat Cutting Oil" (commonly undiluted mineral oils) that have extreme pressure additives (EP additives).

Figure 54. Work stop adjustment components.

Adjust work stop on rod until work stop

contacts workpiece, then tighten set screw to secure.

• For cutting cast iron, cutting fluid is not recommended.

Tip: Using a refractometer or hydrometer to replenish water in water-based cutting fluid can extend the life of blades and cutting fluid, and ensure consistent cutting results.

BIOLOGICAL AND POISON

HAZARD! Use proper personal protection equipment when handling cutting fluid and follow federal, state, and fluid manufacturer requirements to properly dispose of cutting fluid.

-37-

South Bend Tools

Model SB1122

FIRE HAZARD! DO NOT cut magnesium when using oil-water solutions as cutting fluid! Always use cutting fluid intended for magnesium. Water in the solution could cause a magnesium-chip fire.

This bandsaw has a built-in cutting fluid system that can extend the life of your bandsaw blades by lowering the temperature of the blade and workpiece if used properly when cutting.

OPERATION

For Machines Mfd. Since 10/22

You can also install the drip tray on the cabinet edges (see Figure 56) to catch cutting fluid when an operation creates runoff.

CabinetCabinet

EdgeEdge

Drip TrayDrip Tray

Figure 56. Drip tray installed on cabinet edge.

NEVER run machine without cutting fluid in the reservoir or when cutting fluid is below sight glass or you will overheat pump and void warranty!

Add cutting fluid (refer to Adding Cutting Fluid on Page 46), then open cutting fluid valves (see Figure 55) to control the flow of cutting fluid before turning ON machine and starting blade.

Cutting Fluid ValvesCutting Fluid Valves

Note: Too much ﬂow at the cutting ﬂuid valves

will make a mess and can make the work area unsafe; not enough ﬂuid at the cut will overheat the blade, causing the blade teeth to load up and break.

IMPORTANT: Monitor cutting fluid level frequently to keep system working properly. DO NOT let cutting fluid level fall below sight glass shown in Figure 57. Chip screen shown in Figure 57 must also be kept clear so cutting ﬂuid can recycle to the cutting ﬂuid reservoir.

MAINTENANC E

For Machines Mfd. Since 10/22

Maintenance Schedule

Always disconnect machine from power before performing maintenance or serious personal injury may result.

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

Ongoing

• Check/correct loose mounting bolts.

• Check/correct damaged or dull saw blade.

• Check/correct worn or damaged wires.

• Clean/protect unprotected cast-iron surfaces.

• Clean metal chips from upper and lower wheel areas.

• Correct any other unsafe condition.

Weekly

• Lubricate blade and blade guides.

Lubricate blade tension leadscrew and slides.

•

Clean and lubricate vise leadscrew.

•

Monitor cutting fluid level fill/change as

• needed for operation.

Cleaning

Use a brush and shop vacuum to remove chips and other debris from the working surfaces. Periodically remove the blade and thoroughly clean all metal chips or built-up grease from wheel surfaces and blade housing.

Remove any rust build-up from unpainted cast iron surfaces of your machine and treat with a non-staining lubricant after cleaning.

Keep unpainted cast iron surfaces rust-free with regular applications of a quality metal protectant.

Lubrication

An essential part of lubrication is cleaning the components before lubricating them. This step is critical because dust and chips build up on lubricated components, which makes them hard to move. Simply adding more grease to builtup grime will not result in smooth-moving parts. Clean the components in this section with mineral spirits before applying lubrication.

All bearings are sealed and permanently lubricated. Leave them alone until they need to be replaced.

The following are the main components that need to be lubricated:

• Blade and blade guides

• Blade tension leadscrew

• Vise leadscrew

Monthly

• Monitor hydraulic fluid level and change fluid after first 50 hours of use, then every 6 months.

Change cutting fluid.

•

Hydraulic System Maintenance

Always wear safety goggles when servicing the hydraulic system to prevent eye injury.

The hydraulic system must be maintained on a regular basis and kept in good operating condition to avoid premature wear of moving parts, hoses, and valves.

If you have never maintained a hydraulic system before, WE STRONGLY RECOMMEND that you read books, get formal training, or seek the help of a qualiﬁed hydraulic service technician.

Hydraulic systems are highly pressurized and hydraulic fluid is hot after use. Should a leak or malfunction take place, any maintenance to hydraulic lines and valves should only occur when hydraulic pressure has been relieved and fluid has cooled.

Cutting Fluid System Maintenance

The cutting ﬂuid system consists of a reservoir, pump, and hoses with valves. The pump pulls cutting ﬂuid from the reservoir and sends it to the valves, which control the ﬂow of cutting ﬂuid. As the cutting ﬂuid leaves the work area, it drains through the machine cabinet, where the swarf and metal chips are screened out, and back into the reservoir.

Although most swarf from machining operations is screened out of the cutting ﬂuid before it returns to the tank, small particles will accumulate in the bottom of the reservoir in the form of sludge. To prevent this sludge from being pulled into the pump and damaging it, the pump's intake is positioned above the bottom of the tank. This works well when the tank is regularly cleaned; however, if excess sludge is allowed to accumulate, the pump will inevitably begin sucking it up.

Hazards

As cutting ﬂuid ages and gets used, dangerous microbes can proliferate and create a biological hazard. The risk of exposure to this hazard can be greatly reduced by replacing the old cutting ﬂuid on a monthly basis, or as indicated by the manufacturer of the cutting ﬂuid.

When working with the cutting ﬂuid, minimize exposure to your skin, eyes, and lungs by wearing the proper PPE (Personal Protective Equipment), such as long-sleeved waterproof gloves, protective clothing, splash-resistant safety goggles, and a NIOSH-approved respirator.

Adjusting Headstock Travel Limits

The Model SB1122 is equipped with a limit switch that stops the blade motor when a cut is finished, a downfeed stop bolt that stops the headstock from lowering when it reaches the end of its travel, and a stop bolt for when the headstock reaches its full height.

For Machines Mfd. Since 10/22

Limit SwitchLimit Switch

If the headstock does not completely cut through a workpiece before it stops lowering or before the blade stops, or if the blade cuts into the vise table, you will need to adjust the limit switch and the downfeed stop bolt.

Testing Downfeed Travel Limit

1. Lower headstock as far as it will go. When

headstock stops, blade should stop and be just below vise table, but not contacting it.

— If blade stops and is just below vise table,

but not contacting it, no adjustment is required.

— If headstock stops when blade is just

below vise table, but not contacting it, but blade does not stop, refer to Adjusting Downfeed Limit Switch.

— If blade contacts vise table, raise

headstock until blade is just below vise table surface. Refer to Raising Downfeed Travel Limit.

Squaring Blade to Table

A blade that is perpendicular to the vise table surface provides the best cutting results with minimal side loading and blade wear. This adjustment has been made at the factory and should not need to be adjusted under normal circumstances. However, if you ﬁnd the saw is not cutting square, you may need to adjust the blade. Only make this adjustment after ruling out other potential factors, such as excessive feed rate or the top blade guide being adjusted too far away from the workpiece.

This bandsaw is equipped with a universal motor that uses two carbon brushes to transmit electrical current inside the motor. These brushes are considered to be regular "wear items" or "consumables" that will need to be replaced during the life of the motor. The frequency of required replacement if often related to how much the motor is used and how hard it is pushed.

Replace the carbon brushes at the same time when the motor no longer reaches full power, or when the brushes measure less than brushes are
