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.

Model G0887 (Mfd. Since 01/19)

Additional Safety for Hydraulic Systems

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

INJECTION INJURIES. Immediately seek medi-

cal 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 dust-free 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 or death.

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 highpressure 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 performing any service or maintenance. Always 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 hazards.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

-12-

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results.

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 this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

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

Extension cords cause voltage drop, which can 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 be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding 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 a qualified electrician or 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.

Grounding Instructions

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

The power cord and plug specified under “Circuit Requirements for 220V” has an equipment-grounding wire and a grounding prong. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances (see figure below).

Correcting Phase Polarity

This sub-section is provided for troubleshooting 3-phase power connections. If you discover during the test run that the machine will not operate, or that the motor runs backwards, the plug may be wired "out of phase," meaning that the polarity is incorrectly wired. This is a common situation with 3-phase power and it is easy to correct.

To correct phase polarity:

DISCONNECT MACHINE FROM POWER!

Open electrical cabinet and swap wires con-

nected to R and S terminals (see Figure 16).

We do not recommend connecting this machine to a phase converter to supply 3-phase power as it could damage or decrease the life of sensitive electrical components.

Connecting Plug to Power Cord

To connect plug to power cord, install L15-30 plug on end of power cord per plug manufacturer's instructions. If no instructions were included, use wiring diagram on Page 81.

Note About Extension Cords: Using an incorrectly-sized extension cord may decrease the life of electrical components on your machine. If you must use an extension cord, refer to Extension

Cords on Page 14 for more information.

Operation Tips

The main power switch can be disabled by removing the key, as shown below. Disabling the switch in this manner can prevent unauthorized operation of the machine, which is important if it is not kept inside an access-restricted building or in a location where children may be present.

IMPORTANT: Disabling the switch only restricts its function. It is not a substitute for disconnecting machine from power when adjusting or servicing.

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

• Use auto operation mode to speed production.

• Allow blade to reach full speed before cutting 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.

always disable machine unattended. Make sure to place key in a well-hidden or secure location!

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

Wait until blade has completely stopped

• before removing workpiece from 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 potential danger.

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

• Use coolant when possible to increase blade life.

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

Workpiece

Inspection

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

Selecting Blades

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

Blade Terminology

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 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.

• 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.

Standard or Raker: Equally spaced teeth set

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

Variable Pitch (VP): Varying gullet depth and tooth spacing, "0" rake angle, excellent chip removing capacity, and smooth cutting.

To select correct blade pitch:

Measure material thickness. This measure-

ment 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 23, and read across to find workpiece thickness you need to cut.

3. 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.

The "Cutting Speed Rate Recommendation"

chart, which is located on the machine just below the Blade Pitch Chart, offers guidelines for various metals, given in feet per minute (FPM). Refer to Blade Speed Chart section on Page 32 for further details.

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.

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 feed rate and blade speed, and pay attention to the chip characteristics (Refer to Blade Speed Chart on Page 32 and Chip Inspection Chart on Page 33). 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.

Dull or damaged teeth.

•

• Improperly-tensioned blade.

Left blade guide assembly set too far from 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.

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 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.

Use the Chip Inspection Chart on Page 33 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 rate by half for first 50–100 in2 of material cut.

-30-

To avoid twisting blade when cutting, adjust

feed rate when total width of blade is in cut.

Model G0887 (Mfd. Since 01/19)

Setting Blade Feed

Changing Blade

Rate

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

If the feed rate is not consistent, the headstock spring tension (see Page 73) or flow control valve (see Page 77) may need to be adjusted.

During operation, pay attention to the chips being produced from the cut and compare them to the Chip Inspection Chart on Page 33 to properly set the downfeed rate.

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

To set blade feed rate:

Speed

Model G0887 blade speeds: 106–315 FPM.

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:

1. Turn bandsaw ON and allow motor to reach

full speed.

2. Rotate blade speed dial (see Figure 25) clockwise to decrease blade speed and counterclockwise to increase blade speed until blade speed display shows desired speed.

Push hydraulic pump button ( ) to turn

hydraulic pump ON.

Push raise headstock button ( ) and raise

headstock to required height for workpiece.

Adjust blade feed-rate dial shown in Figure 24

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

Tensioning Blade

— If there is just enough space to fit fin-

gernail, then blade tracking is properly adjusted. Continue to

Step 3.

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.

The blade tension failure indicator light will illuminate and the control panel will beep (see Identifying Failures on Page 40) if the bandsaw is turned ON and the tension is not set correctly.

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

The Model G0887 has two operation modes: automatic and manual. Manual mode includes the controls necessary to prepare a workpiece for a cutting operation while automatic mode will complete the cut through a series of pre-established settings. Manual mode can be used to accomplish the same operation as the automatic mode, but the automatic mode requires less user intervention and therefore result in less user error.

See the following steps for the controls required for each to accomplish a typical cutting operation (see Figure 42).

8. Proceed to Performing an Automatic Cut.

Performing an Automatic Cut

Automatic mode can only be used to perform a cut when the preceding manual setup steps have been performed (see Preparing a Cut).

To perform an automatic cut:

Open coolant valves (see Figure 43).

Figure 42. Manual and automatic controls.

Preparing a Cut

Plan your cut before connecting to power, and determine whether the vise or support vise components will need to be moved out of the blade path (see Using Vise on Page 42).

To prepare a cut:

Connect machine to power and turn both

master power switches ON.

Enter manual mode ( ).

3. Turn on hydraulic pump ( ).

4. Set headstock height (see Setting Headstock Height on Page 40).

System

Coolant 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 coolant. 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 coolant. 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).

• For cutting cast iron, coolant is not recommended.

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.

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.

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.

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.

IMPORTANT: Monitor coolant level frequently to keep system working properly. DO NOT let coolant level fall below halfway level on filter screen (see Figure 58).

NEVER run machine without coolant in the reservoir or when coolant is below low mark or you will overheat pump and void warranty!

Using Coolant System

Add coolant (refer to Adding Coolant on Page

57) before using coolant system.

Turn coolant pump ON with the coolant pump button ( to control flow of cutting fluid (see Figure 57).

Always wear safety goggles when servicing the hydraulic system.

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.

Checking Hydraulic Pressure

The hydraulic system pressure should not exceed 498 PSI. Use the following steps to check the system pressure and adjust it as needed.

Maintenance

The coolant system consists of a reservoir, pump, and hoses with valves. The pump pulls coolant from the reservoir and sends it to the valves, which control the flow of coolant. As the coolant leaves the work area, it drains through the machine base, 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 coolant 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 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 coolant on a monthly basis, or as indicated by the manufacturer of the cutting fluid.

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.

Adjusting

Downfeed Stop Bolt

If the blade does not travel far enough to complete the cut, or the blade contacts the vise table, then the downfeed stop bolt will need to be adjusted. When the downfeed stop bolt is adjusted, the downfeed limit switch should be adjusted to match so the blade and coolant pump stop at the end of the cut.

Tool Needed Qty

Open-End Wrenches 17, 30mm ..................1 Ea.

To adjust downfeed stop bolt:

6. Adjust limit switch hex bolt until it just touches

limit switch, then tighten jam nut against tension limit bracket to secure (see Figure 112). Switch should not be depressed.

7. Install blade tension assembly cover.

1. Without starting blade, lower headstock all the

way. When headstock stops, blade should be just below vise table, but not contacting it.

— If blade contacts vise table, raise head-

stock until blade is just below vise table surface.

DISCONNECT MACHINE FROM POWER!

3. Loosen stop bolt jam nut, then adjust

downfeed stop bolt until head of stop bolt contacts bottom of headstock (see

Jam Nut

Figure 113).

8. Connect machine to power and turn blade tension handwheel 1⁄2 turn counterclockwise.

Try to start hydraulic motor.

— If motor does not start, blade tension limit

switch is working correctly and no adjustment is required.

— If motor does start, repeat Steps 4–8 until

hydraulic motor does not start without correct blade tension.

Adjusting

Headstock Spring

The spring under the headstock that controls downward pressure of the headstock during cutting operations should have the correct tension. The tension should only be adjusted if tension is too loose, resulting in premature blade dulling or crooked cuts. Consult the Troubleshooting section beginning on Page 60 to confirm this is the source of the problem before adjusting.

Adjust cap screws shown in Figure 115 to increase or decrease spring tension.

5. Tighten both jam nuts against base to pre-

vent stop bolts from loosening during use.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.

EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.
