-6- G0457 14" Industrial Bandsaw (Mfd. Since 5/11)

WARNING

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.

Additional Safety for Bandsaws

⚠WARNING

Serious cuts, amputation, or death can occur from contact with the moving saw blade during operation or if blade breakage occurs. To reduce this risk, anyone operating this machine MUST completely heed the hazards and warnings below.

HAND PLACEMENT. Placing hands or fingers in line with blade during operation may result in serious injury if hands slip or workpiece moves unexpectedly. Do not position fingers or hands in line with blade, and never reach under table while blade is moving.

SMALL/NARROW WORKPIECES. If hands slip during a cut while holding small workpieces with fingers, serious personal injury could occur. Always support/feed small or narrow workpieces with push sticks, push blocks, jig, vise, or some type of clamping fixture.

UPPER BLADE GUIDE SUPPORT. To reduce exposure of operator to blade and provide maximum blade support while cutting, keep upper blade guides adjusted to just clear workpiece.

FEED RATE. To avoid risk of workpiece slipping and causing operator injury, always feed stock evenly and smoothly.

BLADE CONDITION. Dull blades require more effort to perform cut, increasing risk of accidents. Do not operate with dirty, dull, cracked or badly worn blades. Inspect blades for cracks and missing teeth before each use. Always maintain proper blade tension and tracking while operating.

CLEARING JAMS AND CUTOFFS. Always stop bandsaw and disconnect power before clearing scrap pieces that get stuck between blade and table insert. Use brush or push stick, not hands, to clean chips/cutoff scraps from table.

BLADE CONTROL. To avoid risk of injury due to blade contact, always allow blade to stop on its own. DO NOT try to stop or slow blade with your hand or the workpiece.

GUARDS/COVERS. Blade guards and covers protect operator from the moving bandsaw blade. The wheel covers protect operator from getting entangled with rotating wheels or other moving parts. ONLY operate this bandsaw with blade guard in proper position and wheel covers completely closed.

BLADE SPEED. Cutting workpiece before blade is at full speed could cause blade to grab workpiece and pull hands into blade. Allow blade to reach full speed before starting cut. DO NOT start machine with workpiece contacting blade.

CUTTING TECHNIQUES. To avoid blade getting pulled off wheels or accidentally breaking and striking operator, always turn bandsaw OFF and wait for blade to come to a complete stop before backing workpiece out of blade. DO NOT back workpiece away from blade while bandsaw is running. DO NOT force or twist blade while cutting, especially when sawing small curves. This could result in blade damage or breakage.

WORKPIECE SUPPORT. To maintain maximum control and reduce risk of blade contact/breakage, always ensure adequate support of long/large workpieces. Always keep workpiece flat and firm against table/fence when cutting to avoid loss of control. If necessary, use a jig or other work-holding device.

⚠WARNING

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 may result in serious personal injury or property damage.

SECTION 2: POWER SUPPLY

Availability

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.

WARNING Electrocution, fire, shock, or equipment damage may occur if machine is not properly grounded and connected to power supply.

Full-Load Current Rating

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.

• Full-Load Current Rating at 220V ........ 9.5 Amps
• Full-Load Current Rating at 110V ........ 19 Amps

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.

Circuit Information

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.)

CAUTION For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or electrical codes in your area.

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.

Circuit Requirements for 220V

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

For 220V operation: This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (see following figure). 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.

Figure 1. Typical 6-15 plug and receptacle.

For 110V operation: The plug specified in the circuit requirements has a grounding prong that must be attached to the equipment-grounding wire inside the included power cord. The plug must only be inserted into a matching receptacle (see following figure) that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 2. Typical 5-20 plug and receptacle.

⚠WARNING

Serious injury could occur if you connect machine to power before completing setup process. DO NOT connect to power until instructed later in this manual.

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.

-10- G0457 14" Industrial Bandsaw (Mfd. Since 5/11)

Extension Cords

We do not recommend using an extension cord with this machine. If you must use an extension 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:

• Minimum Gauge Size at 110V ........ 12 AWG
• Minimum Gauge Size at 220V ........ 14 AWG
• Maximum Length (Shorter is Better) ........ 50 ft.

Voltage Conversion

The voltage conversion MUST be performed by a qualified electrician. To perform the voltage conversion, replace the power cord, install the correct plug, and rewire the motor to the new voltage, according to the provided wiring diagram on Page 52.

Note: If the diagram included on the motor conflicts with the one in this manual, the motor may have changed since the manual was printed. Use the diagram provided inside the motor wiring junction box.

To convert the machine to 110V:

1. DISCONNECT MACHINE FROM POWER!
2. Replace the power cord with one that matches the cord specifications under Circuit Recommendations for 110V on Page 9.
3. Replace the 6-15 plug on the power cord with a NEMA 5-20 plug.
4. Re-wire the motor as illustrated in the wiring diagram.

Disabling & Locking Switch

The ON/OFF switch can be disabled and locked by inserting a padlock through the ON button, as shown. Locking the switch in this manner can prevent unauthorized operation of the machine, which is especially important if the machine is not stored inside an access-restricted building.

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

Figure 3. Switch disabled by a padlock.

⚠WARNING

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

NOTICE

The padlock shaft diameter is important to the disabling function of the switch. With any padlock used to lock the switch, test the switch after installation to ensure that it is properly disabled.

Dust Collection

CAUTION

DO NOT operate the Model G0457 without an adequate dust collection system. This saw creates substantial amounts of wood dust while operating. Failure to use a dust collection system can result in short and long-term respiratory illness.

Recommended CFM at Dust Port: 400 CFM Do not confuse this CFM recommendation with the rating of the dust collector. To determine the CFM at the dust port, you must consider these variables: (1) CFM rating of the dust collector, (2) hose type and length between the dust collector and the machine, (3) number of branches or wyes, and (4) amount of other open lines throughout the system. Explaining how to calculate these variables is beyond the scope of this manual. Consult an expert or purchase a good dust collection "how-to" book.

To connect a dust collection hose:

1. Fit the 4" dust hose over the dust port, as shown in Figure 21, and secure in place with a hose clamp.
2. Tug the hose to make sure it does not come off.

Note: A tight fit is necessary for proper performance.

Figure 21. Dust hose attached to dust port.

Blade Tracking

The blade tracking is primarily affected by the tilt of the upper wheel, also known as "Center Tracking"; and the alignment of both wheels, also known as "Coplanar Tracking." (For Coplanar Tracking, see the Wheel Alignment instructions on Page 49.)

The wheels on the Model G0457 were aligned at the factory, so Center Tracking is the only adjustment that needs to be performed when the saw is new.

To center track the blade:

1. DISCONNECT BANDSAW FROM POWER!
2. Adjust the upper and lower guide bearings and support bearings as far away as possible from the blade.
3. Open the upper wheel cover.
4. Adjust blade tension until the mark on the blade tension scale matches the size of the installed blade.

CAUTION The cast iron spokes may have sharp edges and the blade teeth may extend beyond the edge of the wheel, creating a laceration hazard. Be careful when turning the wheels by hand.

5. Spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel. Refer to Figure 22 for an illustration of this concept. —If the blade rides in the center of the upper wheel and is centered on the peak of the wheel crown, then the bandsaw is already tracked properly and no further adjustments are needed at this time. —If the blade does not ride in the center of the upper wheel and is not centered on the peak of the wheel crown, then continue with the following steps.

Figure 22. Center tracking profiles.

6. Loosen the tracking control lock knob (Figure 23) so that the tracking control knob will rotate for adjustments.

Figure 23. Location of tracking control knob.

7. Spin the upper wheel with one hand and rotate the tracking control knob with the other hand to make the blade ride in the center of the bandsaw wheel tire.
8. Tighten the tracking control lock knob and close the upper wheel cover.

For the best performance from your saw, regularly maintain the proper tracking of the blade.

NOTICE Changes in the blade tension may change the blade tracking.

Test Run

Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly.

If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the SERVICE section of this manual can help.

⚠WARNING

Serious injury or death can result from using this machine BEFORE understanding its controls and related safety information. DO NOT operate, or allow others to operate, machine until the information is understood.

⚠WARNING

DO NOT start machine until all preceding setup instructions have been performed. Operating an improperly set up machine may result in malfunction or unexpected results that can lead to serious injury, death, or machine/property damage.

To test run machine:

1. Clear all setup tools away from machine.
2. Connect machine to power supply.
3. Turn the machine ON.
4. Listen and watch for abnormal noises or actions. The machine should run smoothly with little or no vibration or rubbing noises. —Strange or unusual noises must be investigated and corrected before operating the machine further. Always disconnect the machine from power when investigating or correcting potential problems.
5. Turn the machine OFF.

Table Stop Calibration

The adjustable positive stop allows the table to be reset 90° to the blade after tilting to the right.

To set the positive stop:

1. DISCONNECT BANDSAW FROM POWER!
2. Adjust blade tension until the mark on the blade tension scale matches the size of the installed blade.
3. Loosen the hex nut that locks the positive stop bolt in place and loosen the table tilt hand knobs.
4. Raise the guide post and place a machinist's square on the table next to the side of the blade, as illustrated in Figure 24. Adjust the table square with the blade, then secure with the table tilt knobs.

Blade → Square Table Figure 24. Squaring table to blade.

5. Adjust the positive stop bolt to the table.
6. Secure the positive stop bolt by tightening the hex nut against the trunnion bracket.
7. Check the adjustment for accuracy once you have tightened the hex nut.

Table Tilt Calibration

The pointer on the table tilt scale must be calibrated in order for the scale reading to be accurate.

To calibrate the pointer on the table tilt scale:

1. Make sure that the blade is tensioned and is tracking correctly, and that the table is 90° to the blade (see Table Stop Calibration on Page .
2. Loosen the screw on the pointer (Figure 25), but do not remove it.

Figure 25. Table tilt scale.

3. Align the tip of the pointer with the 0° mark on the table tilt scale.
4. Tighten the screw on the pointer so that the pointer is locked in place.

Table Alignment

To ensure cutting accuracy when the table is first installed, the table should be aligned so that the miter slot is parallel to the bandsaw blade. This procedure works best with a 3/4" blade installed.

To align the table so the miter slot is parallel to the bandsaw blade:

1. Make sure that the blade is tracking properly and that it is correctly tensioned.

2. DISCONNECT BANDSAW FROM POWER!

3. Loosen the trunnion bolts that secure the trunnions to the table.

4. Place an accurate straightedge along the blade. The straightedge should lightly touch both the front and back of the blade.

   Note: Make sure the straightedge does not go across a tooth.

5. Use a fine ruler to gauge the distance between the straightedge and the miter slot. The distance you measure should be the same at both the front and the back of the table (see Figure 26).

6. Adjust the table as needed for proper alignment.

7. Tighten the trunnion bolts.

Figure 26. Measuring miter slot parallelism with the blade.

Fence Alignment

To ensure cutting accuracy when the fence is first installed, the fence should be aligned with the miter slot.

To align the fence parallel with the miter slot:

1. If the fence is mounted on the left-hand side of the blade, remove it and remount it next to the miter slot.
2. Loosen the four cap screws located on the top face of the fence (Figure 27).

Figure 27. Four fence cap screws.

3. Adjust the fence face parallel with the edge of the miter slot.
4. Tighten the four cap screws, being careful not to move the fence.

Miter Gauge

The miter gauge needs to be calibrated to the blade when it is first mounted in the miter slot.

To calibrate the miter gauge:

1. Place one edge of a machinist's square against the face of the miter gauge and the other side against the blade face, as shown in Figure 28.

Figure 28. Squaring miter gauge to blade.

2. Loosen the lock knob on the miter gauge and adjust it flush with the edge of the square.
3. Tighten the lock knob, and verify the setting.

Note: Sometimes the tightening procedure can affect the adjustment.

4. Loosen the screw that secures the angle pointer and adjust the pointer to the 0° mark on the scale.
5. Retighten the screw that secures the angle pointer.

Blade Tensioning

A properly tensioned blade is essential for making accurate cuts and is a prerequisite for making many bandsaw adjustments. The blade tension scale shows the approximate tension, but the steps below will allow you to get the optimum tension for the installed blade.

To tension the bandsaw blade:

1. Make sure you have completed the Test Run procedure on Page 21 and that the blade is tracking properly.

2. Raise the upper blade guide assembly as high as it will go, and adjust the upper and lower guide blocks as far away from the blade as possible.

   Note: This procedure will NOT work if the guide blocks have any contact with the blade.

3. Adjust blade tension until the mark on the blade tension scale matches the size of the installed blade.

   Note: This scale can only be considered a general guide. Complete the following steps to accurately set blade tension.

4. Turn the bandsaw ON.

5. Slowly release the tension one quarter of a turn at a time. When you see the bandsaw blade start to flutter, stop decreasing the tension.

6. Now, slowly increase the tension until the blade stops fluttering, then tighten the tension another quarter turn.

7. Look at what the tension gauge reads and use that as a guide for tensioning that blade in the future.

   Note: Always de-tension the blade after use to increase blade life and reduce strain on the bandsaw components.

NOTICE

After blade tension and tracking are set correctly, you MUST properly adjust the upper and lower support bearings and guide-block assemblies into position before cutting.

Adjusting Support Bearings

The support bearings are positioned behind the blade for support during cutting operations. Proper adjustment of the support bearings is an important part of making accurate cuts and also keeps the blade teeth from coming in contact with the guide bearings while cutting.

To adjust the support bearings:

1. Make sure that the blade is tracking properly and that it is correctly tensioned.

2. DISCONNECT BANDSAW FROM POWER!

3. Familiarize yourself with the support bearing controls shown in Figure 29.

Figure 29. Support bearing controls.

-24- G0457 14" Industrial Bandsaw (Mfd. Since 5/11)

4. Loosen the assembly lock bolt.

5. Rotate the blade guide assembly side-to-side, until the blade is perpendicular to the face of the support bearing as illustrated in Figure 30.

Figure 30. Blade should be perpendicular (90°) to the face of the support bearing.

6. Tighten the assembly lock bolt.

7. Loosen the thumbscrew on the support bearing adjustment shaft.

8. Place a 0.016" feeler gauge between the support bearing and the blade, and use the upper knurled knob to position the bearing 0.016" away from the back of the blade, as illustrated in Figure 31.

Figure 31. Blade should be aligned approximately 0.016" away from the bearing edge.

Note: For a quick gauge, fold a dollar bill in half twice (four thicknesses of a dollar bill is approximately 0.016") and place it between the support bearing and the blade as shown in Figure 32.

Figure 32. Dollar bill folded twice to make an approximate 0.016" gauge.

9. Tighten the thumbscrew to keep the support bearing locked in place.

10. Repeat Steps 4–9 for the lower support bearings.

NOTICE

Whenever changing a blade or adjusting tension and tracking, the upper and lower blade support bearings and blade guide bearings must be properly adjusted before cutting operations.

Blade Guide Adjustments

The blade guides consist of an upper and lower set of ball bearings that provide side-to-side support to help keep the blade straight while cutting. The blade guides are designed to be adjusted in two ways—forward/backward and side-to-side.

To adjust the upper and lower blade guides:

1. Make sure that the blade is tracking properly and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the blade guide controls shown in Figure 33.

Figure 33. Blade guide controls.

4. Loosen the thumbscrew on the lateral adjustment rod.
5. Rotate the lower knurled knob to position the blade guides so the edges of the bearings are 0.016" behind the blade gullets, as illustrated in Figure 34.

Note: The 0.016" spacing is ideal, although with larger blades it may not be possible. In such cases, adjust the guide bearings as far forward as possible to the blade gullets, and still maintain the proper support bearing spacing adjustment.

Figure 34. Lateral adjustment of blade guides.

NOTICE
Make sure that the blade teeth will not contact the guide bearings when the blade is against the rear support bearing during the cut or the blade teeth will be ruined.

6. Tighten the thumbscrew on the lateral adjustment rod.
7. Loosen the cap screws.
8. With the 4mm hex wrench, rotate the center portion of the blade guide bearings to laterally position the bearings 0.004" away from the blade.

Note: 0.004" is approximately the thickness of a piece of paper.

9. Tighten the cap screw to lock the blade guide bearings in position.
10. Repeat Steps 4–9 for the lower guides.

NOTICE
Whenever changing a blade or adjusting tension and tracking, the upper and lower blade support bearings and guide bearings must be properly adjusted before cutting operations.
