-9-

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine for damaged, loose, or mis-adjusted parts—or any condition that could affect safe operation. Immediately repair/replace BEFORE operating machine. For your own safety, DO NOT operate machine with damaged parts!

MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab and pull the plug—NOT the cord. Pulling the cord may damage the wires inside. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663.

Additional Safety for

Horizontal Metal Bandsaws

Serious injury or death can occur from getting fingers, hair, or clothing entangled in rotating or moving parts or making direct contact with the moving blade. To minimize risk of injury, anyone operating this machine MUST completely heed hazards and warnings below.

BLADE CONDITION. Do not operate with dull,

cracked, or badly worn blade. Inspect blades for cracks and missing teeth before each use.

HAND PLACEMENT. Never position hands or fingers in line with the cut or under bandsaw headstock while lowering or operating. Hands could be cut or crushed.

BLADE GUARD POSITION. Adjust blade guard as close to workpiece as possible before cutting to minimize operator exposure to unused portion of blade.

ENTANGLEMENT HAZARDS. Do not operate this saw without blade guard in place. Loose clothing, jewelry, long hair and work gloves can be drawn into working parts.

BLADE REPLACEMENT. When replacing blades, disconnect the machine from power, wear gloves to protect hands and safety glasses to protect eyes.

HOT SURFACES. Contact with hot surfaces from machine components, ejections of hot chips, swarf, and the workpiece itself can cause burns.

WORKPIECE HANDLING. Always properly support workpiece with table, vise, or some type of support fixture. Always secure workpiece in vise before cutting. Never hold the workpiece with your hands during a cut.

UNSTABLE WORKPIECES. Avoid cutting workpieces that cannot be properly supported or clamped in a vise or jig, because they can unexpectedly move while cutting and draw the operator’s hands into the blade causing serious personal injury. Examples are chains, cables, round or oblong-shaped workpieces, and those with internal or built-in moving or rotating parts, etc.

FIRE HAZARD. Use EXTREME CAUTION if cutting magnesium. Using the wrong cutting fluid could lead to chip fire and possible explosion.

CUTTING FLUID SAFETY. Cutting fluids are poisonous. Always follow manufacturer’s cuttingfluid safety instructions. Pay particular attention to contact, contamination, inhalation, storage and disposal warnings. Spilled cutting fluid invites slipping hazards.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time.

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.

Model G0812 (Mfd. Since 2/16)

The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean.

Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.

There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer’s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

Cleanup

Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Av oi d using these products to clean machinery.

Put on safety glasses.

Coat the rust preventative with a liberal

amount of cleaner/degreaser, then let it soak for 5–10 minutes.

Site Considerations

Weight Load

Refer to the of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual.

See below for required space allocation.

Anchoring to Floor

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.

If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to

and gather all goes smoothly, first clean any

Note: It is sometimes possible to flip the

blade inside out, in which case the blade will be installed in the wrong direction. After installing, check to make sure the blade teeth face the same direction as blade travel (see Figure 28). Some blades will have a directional arrow as a guide.

Blade Travel

Figure 28. Example of blade cutting direction.

Tensioning &

Tracking Blade

Proper blade tension is essential to long blade life, straight cuts, and efficient cutting. The Model G0812 features a blade tension indicator to assist you with blade tensioning.

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

Loosen blade tension at the end of each day to prolong blade life.

8. Use one hand to hold blade in place, then

work your way around the blade, making adjustments so back of blade lightly touches shoulder of wheels, as shown in Figure 29.

section.

Tensioning Blade

Rotate blade tension handwheel (see Figure 30) clockwise to tension blade and move tip of indicator to correct PSI setting on graduated scale that corresponds with blade type being used.

F o r bi-metal blades, like the one supplied with your machine, set blade tension between 30,000 and 35,000 PSI (start low and adjust up from there only as necessary for accurate cutting results).

For carbon blades, set blade tension at 20,000 PSI.

10. Re-install wheel brush and blade guards, then close and secure wheel cover. Ensure guards do not touch blade.

Reposition left blade guide (refer to Blade

11. Guides on Page 37 for details).

Tracking Blade

The blade tracking has been properly set at the factory. The tracking will rarely need to be adjusted if the bandsaw is used and maintained properly. The blade is tracking properly when the back of the blade lightly touches the shoulder of both wheels during operation (see Figure 31).

Tip: One way to gauge whether the blade is tracking properly is to DISCONNECT MACHINE FROM POWER and slide the end of a fingernail between the end of the blade and the shoulder, with the machine. If there is just enough space to do that, the blade tracking is properly set.

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.

Feeding blade through the workpiece too

•

fast.

Dull or damaged teeth.

•

• Improperly-tensioned blade.

Left blade guide assembly set too high above

•

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

Using a blade with a lumpy or improperly fin-

•

ished braze or weld.

Continuously running the bandsaw when not

in use.

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.

Blade Care &

Break-In

Blade Speed

Blade Care

To prolong blade life, always use a blade with the proper width, set, type, and pitch for each application. Maintain the appropriate feed rate, feed pressure, and blade speed, and pay attention to the chip characteristics (Refer to Blade Speed Chart on Page 30 and Chip Inspection Chart on Page 31). 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 warrant y.

Entanglement Hazard! You MUST install the pulley cover before operating or severe injury may occur.

Model G0812 blade speeds: 95–380 FPM.

During operation, pay attention to the chips being produced from the cut and compare them to the Chip Inspection Chart on Page 31 to properly set the downfeed rate.

NOTICE

Only change speeds while the motor is running. Changing speeds when machine is OFF may result in damage to your machine. Always make sure belt guard is in use.

To change blade speeds:

Use the Chip Inspection Chart on Page 31 as a guide to evaluate the chips and ensure that the optimal blade speed and feed rate are being used.

To properly break-in new blade:

Choose correct speed for blade and material

type.

2. Reduce feed pressure by half for first 50–100

of material cut.

To avoid twisting blade when cutting, adjust

feed pressure when total width of blade is in cut.

1. Turn bandsaw ON and allow motor to reach

full speed.

2. Rotate speed adjustment knob (see Figure 33)

clockwise to decrease blade speed and counterclockwise to increase blade speed.

The best method for choosing the cutting speed and feed 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 feed rate/ pressure, blade speed, or both.

Feed Rate

Work Stop

The speed at which the saw blade will cut through a workpiece is controlled by blade type, feed rate, and feed pressure. The feed rate is controlled by the feed rate dial on the control panel.

Note: If a lubricant is used on the cut, the feed rate can be increased by approximately 15%.

To set feed rate:

Raise headstock to highest position.

2. Adjust feed rate dial shown in Figure 36

to desired feed rate from 0 (slowest) to 10 (fastest).

Coolant

While simple in concept and function, many issues must be taken into account to find and use the correct coolant. Always follow all product warnings and contact the fluid manufacturer for unanswered questions.

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

Coolant System

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

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

• 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).

• For cutting cast iron, coolant is not recommended.

Remember: Too much flow at the coolant nozzles will make a mess and can make the work area unsafe by creating a slipping hazard; and not enough fluid at the cut will heat the blade, causing the blade teeth to load up and break.

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

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

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

The cutting fluid pump has two modes controlled by the switch on the control panel. The low-pressure setting ( directly to the blade through the fluid nozzles. The high-pressure setting ( pressure to the auxiliary sprayer for rinsing metal chips into the reservoir. See Coolant section for additional information.

) is used to supply high

Using Coolant System

Add coolant (refer to Adding Coolant on Page

48) before using coolant system.

Turn cutting fluid pump switch ( sure position ( control flow of cutting fluid (see Figure 54).

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

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 horizontal cutting:

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

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

Figure 55. Halfway level on filter screen.

Using Spray Gun

1. Position splash guard on side of base near

location of spraying operation.

Close coolant control valves.

• Use vise close ( tons to speed production.

• Let the blade reach full speed before engaging the 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 feed rate.

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

Wait until the blade has completely stopped

• Use coolant when possible to increase blade life.

Loosen blade tension at the end of each day to prolong blade life.

Workpiece Inspection

• 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.

Some metal workpieces are not safe to cut with a metal cutting bandsaw; instead, a different tool or machine should be used.

Before cutting, inspect the material for any of the following conditions and take the 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 forces from this bandsaw during cutting; instead, use a shear, nibblers, or sheet metal nippers to cut these pieces.

• Unstable Workpieces: Workpieces that can-

not 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.

• Tanks, Cylinders, Containers, Valves, Etc: Cutting into containers that are pressurized or contain gasses 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.

Coolant System

Service

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

Although most swarf from machining operations is screened out of the coolant before it returns to the tank, small particles will accumulate in the bottom of the tank 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 coolant 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 fluid on a monthly basis, or as indicated by the fluid manufacturer.

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

BIOLOGICAL & POISON

HAZARD! Use correct personal protection equipment when handling coolant. Follow federal, state, and fluid manufacturer requirements for proper disposal.

Preparing Machine for Storage

1. DISCONNECT MACHINE FROM POWER!

2. Thoroughly clean all unpainted, bare metal

surfaces, then coat them with light weight grease or rust preventative. Take care to ensure these surfaces are completely covered but that grease or rust preventative is kept off of painted surfaces.

— If machine will be out of service for only a

short period of time, use quality mediumweight machine oil (not auto engine oil) in place of grease or rust preventative.

Remove old coolant, then add a few drops of

way oil and blow out lines with compressed air.

— If machine will be out of service for only a

short period of time, start machine once a week and run all gear-driven components for a few minutes. This will put fresh coat of gear oil on gearing components inside gearbox.

— If it will be out of service for a long period

of time, drain, then completely fill gearbox with recommended gear oil so components above normal oil level do not develop rust. (Make sure to put a tag on controls as a reminder for re-commissioning process to adjust gear oil level before starting machine.)

Place a few moisture-absorbing desiccant

packs inside of electrical box.

Completely cover machine with tarp or plastic

sheet that will keep out dust and resist liquid or moisture. If machine will be stored in/near direct sunlight, use a cover that will block the sun's rays.

Adjusting Upper & Lower Limit Switches

The upper limit switch should only be adjusted if the blade does not shut off or the headstock does not move back to the top of travel after the cut is complete.

The lower limit switch can be adjusted to limit saw headstock travel to match the height of the workpiece. This speeds up repetitive cuts by eliminating unnecessary saw headstock travel.

To adjust limit switches:

1. Raise headstock several inches, start blade,

and lower headstock. When blade reaches bottom of travel, it should be just below table level but not touching it, and headstock should briefly contact stop bolt (see Figure 87) before blade shuts off and headstock moves back to top of its travel.

Loosen screws that secure blade tension limit

switch (see Figure 86) and slide switch bottom so it just touches switch plate.
