Overview

The bandsaw is one of the most versatile wood cutting tools in the shop. It is capable of performing many different cutting functions, including:

Straight Cuts

• Miters
• Angles
• Compound Angles
• Resawing
• Ripping
• Crosscutting

Irregular Cuts

• Simple and Complex Curves
• Duplicate Parts
• Circles
• Beveled Curves

A properly adjusted and tuned bandsaw can be safer to operate than most other saws and performs many functions with ease and accuracy.

Basic Cutting Tips

Here are some basic tips to follow when operating the bandsaw:

• Replace, sharpen, and clean blades as necessary and make adjustments periodically to keep the saw running in top condition.
• Use light and even pressure while cutting. Light contact with the blade will permit easier line following and prevent undue friction.
• Avoid trying to turn tight corners because this will twist the blade. Remember, you must saw around corners.
• Misuse of the saw or using incorrect techniques is unsafe and results in frustration and poor cuts. Remember—the blade does the cutting with the operator's guidance.

Workpiece Inspection

Some wood workpieces are not safe to cut or may require modification before they are safe to cut.

Before making cuts, get in the habit of inspecting all workpieces for the following:

• Material Type: This machine is intended for cutting natural and man-made wood products, laminate covered wood products, and some plastics. Cutting drywall or cementitious backer board creates extremely fine dust and may reduce the life of the bearings. This machine is NOT designed to cut metal, glass, stone, tile, etc.; cutting these materials with this saw may lead to injury.
• Foreign Objects: Nails, staples, dirt, rocks and other foreign objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator or break the blade, which might then fly apart. Always visually inspect your workpiece for these items. If they cannot be removed, do NOT cut the workpiece.
• Large/Loose Knots: Loose knots can become dislodged during the cutting operation. Large knots can cause blade damage. Choose workpieces that do not have large/loose knots or plan ahead to avoid cutting through them.
• Wet or "Green" Stock: Cutting wood with a moisture content over 20% causes unnecessary wear on the blade and yields poor results.
• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and can move unpredictably when being cut. DO NOT use workpieces with these characteristics!
• Minor Warping: Workpieces with slight cupping can be safely supported if the cupped side faces the table or fence. On the contrary, a workpiece supported on the bowed side will rock during a cut, leading to loss of control.

Table Tilt

The bandsaw table will tilt 8° left and 45° right to provide a wide range of cutting options. Most cutting operations are done at 90° and rarely will the table need to be tilted left. Remove the positive stop bolt to tilt the table to the left.

To tilt the table:

1. Loosen the two table trunnion hand knobs.
2. Position the table to the desired angle of tilt. Refer to the angle gauge on the front table trunnion for the tilting angle.
3. Retighten both table trunnion hand knobs.

Guide Post

The guide post, shown in Figure 37, connects the upper blade guide assembly to the bandsaw. The guide post allows the blade guide assembly to move up or down via a rack and pinion. In order to cut accurately, the blade guide assembly must be no more than 1" from the top of the workpiece at all times—this positioning provides the greatest support to the blade.

Figure 37. Guide post controls.

To adjust guide post:

1. Make sure that the blade tension, blade tracking, support bearing, and blade guides are adjusted correctly.
2. Loosen the guide post lock knob shown in Figure 37.
3. Raise/lower the guide post with the adjustment knob to within 1" from the top of the workpiece to the bottom of the blade guide assembly.
4. Lock the guide post in place with the lock knob.

Ripping

Ripping is the process of cutting with the grain of the wood stock. For plywood and other processed wood, ripping simply means cutting down the length of the workpiece.

To rip with the Model G0457:

1. Adjust the fence to match the width of the cut on your workpiece and lock the fence in place.
2. Make sure the bandsaw is properly set up and adjusted as described in SECTION 3: SETUP.
3. Slowly feed the workpiece into the blade and continue with the cut until the blade is completely through the workpiece. Figure 38 shows a typical ripping operation.

Note: If you are cutting narrow pieces, use a push stick to protect your fingers.

Figure 38. Ripping with a push stick.

⚠WARNING

NEVER place fingers or hands in the line of cut. In the event that something unexpected happens, your hands or fingers may be pulled into the blade. ALWAYS use a push stick when ripping narrow pieces. Failure to follow these warnings may result in serious personal injury!

-30- G0457 14" Industrial Bandsaw (Mfd. Since 5/11)

Crosscutting

Crosscutting is the process of cutting across the grain of wood. For plywood and other processed wood, crosscutting simply means cutting across the width of the material.

To crosscut with the Model G0457:

1. Mark the workpiece on the edge where you want to begin the cut.
2. Move the fence out of the way. Place the workpiece evenly against the miter gauge.
3. Line up the mark with the blade.
4. After all safety precautions have been met, turn the bandsaw ON. Slowly feed the workpiece into the blade and continue the cut until the blade is all the way through the workpiece. Figure 39 shows a typical cross-cutting operation.

Figure 39. Crosscutting with miter gauge.

Resawing

Resawing (Figure 40) is the process of cutting a board into two or more thinner boards. The maximum board width that can be resawn is limited by the maximum cutting height of the bandsaw. Maximum cutting height for this bandsaw is 10".

The Model G0457 14" Industrial Bandsaw is capable of resawing, provided the saw is properly set up. Attempting to resaw too wide or too dense of a board may put excessive strain on the blade and cause breakage.

One of the most important considerations when resawing is blade selection. Generally, the wider blade, the better. In most applications, a hook or a skip tooth style will be desirable. Also, since most resawn lumber will be planed smooth, you should choose blades with fewer teeth-per-inch (from 3 to 6). While blades with fewer teeth-per-inch produce rougher cuts, these types of blades offer larger gullet capacities for clearing sawdust, reducing heat buildup and reducing strain on the motor.

Figure 40. Resawing lumber.

To resaw a workpiece:

1. Verify that the bandsaw is set up properly and that the table is perpendicular to the blade.

2. Use the widest blade your bandsaw will accept.

   Note: The blade must also be sharp and clean.

3. Use a fence to guide the workpiece.

4. Set your fence to the desired width of cut and lock it in place.

5. Support the ends of the board if necessary.

6. Turn the bandsaw ON.

7. Using push paddles and a push stick, keep pressure against the fence and table, and slowly feed the workpiece into the moving blade until the blade is completely through the workpiece.

Cutting Curves

When cutting curves, simultaneously feed and turn the stock carefully so that the blade follows the layout line without twisting. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, use either a narrower blade or a blade with more TPI (teeth per inch), or make more relief cuts.

Always make short cuts first, then proceed to the longer cuts. Relief cuts will also reduce the chance that the blade will be pinched or twisted. Relief cuts are cuts made through the waste portion of the workpiece and are stopped at the layout line. As you cut along the layout line, waste wood is released from the workpiece, alleviating any pressure on the back of the blade. Relief cuts also make backing the workpiece out easier, if needed.

NOTICE

The list below displays blade widths and the corresponding minimum radii each size of blade for the Model G0457.

-32- G0457 14" Industrial Bandsaw (Mfd. Since 5/11)

Stacked Cuts

One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stacking a number of workpieces together.

Before making stacked cuts, ensure that both the table and the blade are properly adjusted to 90°. Otherwise, any error will be compounded with each piece cut from the top to the bottom of the stack.

To complete a stacked cut:

1. Align your pieces from top to bottom to ensure that each piece has adequate scrap to provide a clean, unhampered cut.
2. Secure all the pieces together in a manner that will not interfere with the cutting. Hot glue on the edges works well, as do brad nails through the waste portion. (Be careful not to cut into the brads!)
3. On the face of the top piece, lay out the shape you intend to cut.
4. Make relief cuts perpendicular to the outline of your intended shape in areas where changes in blade direction could strain the woodgrain or cause the blade kerf to bind.
5. Cut the stack of pieces as though you were cutting a single piece. Follow your layout line with the blade kerf on the waste side of your line as shown in Figure 41.

CAUTION Cutting into brad nails that are used to secure the multiple pieces can cause the blade to break and may cause an injury to the operator. Be extremely careful of where you are cutting when performing this operation.

Figure 41. Cutting multiple pieces at once.

Blade Information

Selecting the right blade requires a knowledge of the various blade characteristics mentioned below, the type of material you plan to cut, and the type of cut you are going to perform.

Blade Length

Measured by the circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between wheels. The Model G0457 is designed for blades that are 106" long. Refer to the current Grizzly catalog for prices and ordering information.

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the first consideration given to blade selection. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line.

The Model G0457 can use blades from $1/8$" to $3/4$" in width. Always pick the size of blade that best suits your application.

• Curve Cutting: Use the chart in Figure 42 to determine the correct blade for curve cutting. Determine the smallest radius curve that will be cut on your workpiece and use the corresponding blade width.

Figure 42. Blade width radii.

• Straight Cutting: Use the largest width blade that you own. The Model G0457 will accept blades up to $3/4$" wide. Narrow blades can cut tight curves (a small radius) but are not very good at cutting straight lines because they naturally wander (blade lead). However, larger blades are much better at cutting straight lines, but function poorly at cutting small curves because of their size.

Tooth Style

When selecting blades, another option to consider is the shape, gullet size, teeth set and teeth angle—otherwise known as "Tooth Style."

Figure 43 shows the three main categories of tooth style:

Figure 43. Raker, Skip & Hook tooth styles.

• Raker: This style is considered to be the standard because the tooth size and shape are the same as the tooth gullet. The teeth on raker blades usually are very numerous, have no angle, and produce cuts by scraping the material; these characteristics result in very smooth cuts, but do not cut fast and generate more heat while cutting.
• Skip: This style is similar to a raker blade that is missing every other tooth. Because of the design, skip toothed blades have a much larger gullet than raker blades, and therefore, cut faster and generate more heat. However, these blades also leave a rougher cut than raker blades.

• Hook: The teeth on this style have a positive angle (downward) which makes them dig into the material, and the gullets are usually rounded for easier waste removal. These blades are excellent for the tough demands of resawing and ripping thick material.

Tooth Pitch

Usually measured as TPI (teeth per inch), tooth pitch determines the size of the teeth. More teeth per inch (fine pitch) will cut slower, but smoother; while fewer teeth per inch (coarse pitch) will cut rougher, but faster. As a general rule, choose blades that will have at least three teeth in the material at all times. Use fine pitched blades on harder woods and coarse pitched blades on softer woods.

Blade Care

A bandsaw blade is a delicate piece of steel that is subjected to tremendous strain. You can obtain longer use from a bandsaw blade if you give it fair treatment and always use the appropriate feed rate for your operation.

Be sure to select blades with the proper width, style, and pitch for each application. The wrong choice of blades will often produce unnecessary heat which will shorten the life of your blade.

A clean blade will perform much better than a dirty blade. Dirty or gummed up blades pass through the cutting material with much more resistance than clean blades. This extra resistance also causes unnecessary heat.

Blade Breakage

Many conditions may cause a bandsaw blade to break. Blade breakage is unavoidable, in some cases, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to. Blade breakage is also due to avoidable circumstances. Avoidable breakage is most often the result of poor care or judgement on the part of the operator when mounting or adjusting the blade or support guides.

The most common causes of blade breakage are:

• Aligning or adjusting the guides incorrectly.
• Forcing or twisting a wide blade around a curve of short radius.
• Feeding the workpiece into the blade too fast.
• Using a blade with dull teeth or the absence of sufficient set.
• Incorrect tension.
• Setting the top blade guide assembly set too high above the work piece.
• Using a blade with a lumpy or improperly finished braze or weld.
• Continuously running the bandsaw when not in use.

Blade Changes

WARNING Always disconnect power to the machine when changing blades. Failure to do this may result in serious personal injury.

CAUTION All saw blades are dangerous and may cause personal injury. To reduce the risk of being injured, wear leather gloves when handling saw blades.

To remove the blade:

1. DISCONNECT BANDSAW FROM POWER!
2. Release the blade tension by turning the blade tension quick release lever to the left.
3. Remove the table insert and the table pin. Adjust the upper and lower guide bearings as far away as possible from the blade.
4. Open the upper and lower wheel covers, and with gloved hands, slide the blade off both wheels.
5. Rotate the blade 90° and slide it through the slot in the table.

To replace the blade:

1. Slide the blade through the table slot, ensuring that the teeth are pointing down toward the table.

   Note: If the teeth will not point downward in any orientation, the blade is inside-out. Put on heavy gloves, remove the blade, and twist it right side-out.

2. Slip the blade through the guides, and mount it on the upper and lower wheels (Figure 44).

Figure 44. Placing blade on the wheels.

3. Tighten the blade tension quick release.
4. Apply tension to the blade by turning the tension control knob. Rotate the upper wheel slowly by hand as tension is applied to allow the blade to center itself on the wheel. Adjust tracking if needed.
5. Adjust tension as described Page 24.
6. Adjust the upper/lower guide bearings and the support bearings.
7. Close the wheel covers.
8. Replace the table insert and table pin, being sure not to use excessive force when inserting the table pin.

SECTION 6: MAINTENANCE

! WARNING Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.

Schedule

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

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

• Loose mounting bolts.
• Worn or damaged saw blade.
• Worn or damaged wires.
• Any other unsafe condition.

Monthly

• Check for V-belt tension, damage, or wear.
• Clean/vacuum dust buildup from inside cabinet and off motor.

Cleaning & Protecting

Cleaning the bandsaw is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth. If any resin has built up, use a resin dissolving cleaner to remove it.

Protect the unpainted cast iron surfaces on the table by wiping it clean after every use—this ensures moisture from wood dust does not remain on bare metal surfaces. Keep the table rust-free with regular applications of products like G96® Gun Treatment, SLIPIT®, or Boeshield® T-9 (see Accessories section for more details).

Once a month, remove the blade and thoroughly clean all built-up sawdust from the rubber tires on the wheels.

Lubrication

Sealed and pre-lubricated ball bearings require no lubrication for the life of the bearings. All bearings are standard sizes, and replacements can be purchased from our parts department or bearing supply store.

For adjustment controls, an occasional “shot” of light oil is all that is necessary. Wipe off any sawdust with a clean cloth, towel or dry paint brush, and spray on the lubricant. Do not get oil on the pulleys or V-belt because it could cause belt deterioration and slipping.

Guide Post

1. DISCONNECT BANDSAW FROM POWER!
2. Open the upper wheel cover, then lower the guide post so the upper guide bearings almost touch the table.
3. Wipe the old grease off the rack (the long plate with teeth). The old grease will be contaminated with sawdust, so you want to remove as much of it as possible (Figure 55).

Figure 55. Guide post rack lubrication.

4. Use mineral spirits or degreaser to clean any remaining grease from the rack. Make sure to thoroughly wipe off the degreaser or mineral spirits after use so they won't contaminate the new grease.
5. Use a small, clean brush to apply NLGI#2 or equivalent automotive-grade multi-purpose grease to the rack. After applying, rotate the guide adjustment knob several times to distribute the grease.
6. Close the upper wheel cover, and re-adjust the guide post height as necessary.

Blade Tension Leadscrew

1. DISCONNECT BANDSAW FROM POWER!
2. Open the upper wheel cover, then wipe as much of the old grease off the blade tension leadscrew as possible. The old grease will be contaminated with sawdust, so you want to remove as much of it as possible (Figure 35).

Figure 56. Blade tension leadscrew.

3. Use mineral spirits or degreaser to clean any remaining grease from the leadscrew. Make sure to thoroughly wipe off the degreaser or mineral spirits after use so they will not contaminate the new grease.
4. Use a small, clean brush to apply NLGI#2 or equivalent automotive-grade multi-purpose grease to the leadscrew. After applying, rotate the blade tension knob through its full range of motion to distribute the grease.
5. Close the upper wheel cover, and re-adjust the blade and belt tension as necessary.

Table Trunnions

1. DISCONNECT BANDSAW FROM POWER!

2. Wipe the old grease off the bearing surfaces of the table trunnions. Start with the outward side of the table trunnions (Figure 57) when the table is at 0°, then tilt the table to 45° and wipe off the inward side. The old grease will be contaminated with sawdust, so you want to remove as much of it as you can.

   Note: For easiest access to the trunnions and the best cleaning results, consider removing the table during this procedure.

Figure 57. Sides of table trunnions to grease.

3. Use mineral spirits or degreaser to clean any remaining grease from the trunnions. Make sure to thoroughly wipe off the degreaser or mineral spirits after use so they won't contaminate the new grease.
4. Use a small, clean brush to apply NLGI#2 or equivalent automotive-grade multi-purpose grease to the trunnion bearing surfaces. After applying, tilt the table back and forth from 0° to 45° to distribute the grease.

Redressing Rubber Tires

As the bandsaw ages, the rubber tires on the wheels may need to be redressed if they harden or glaze over. Redressing the rubber tires improves blade tracking and reduces vibration/blade lead.

If the rubber tires become too worn, then blade tracking will become extremely difficult. At that point, redressing will no longer be effective and the rubber tires must be replaced.

To redress the rubber tires:

1. DISCONNECT BANDSAW FROM POWER!
2. Put on heavy leather gloves.
3. Remove the blade.
4. Clean any built-up sawdust from the rubber tires.
5. Hold 100 grit sandpaper against the rubber tire and rotate the wheel by hand. Only redress the rubber enough to expose a fresh rubber surface.

Checking V-Belt

To ensure optimum power transmission from the motor to the blade, the V-belt must be in good condition and operate under proper tension. The belt should be checked for cracks, fraying, and wear. Belt tension should be checked at least every 3 months—more often if the bandsaw is used daily.

To check the V-belt:

1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. Push the center of the V-belt. Note the amount of deflection. —If deflection is more than 3/8", tighten the V-belt.
4. Note the condition of the V-belt. —If the V-belt is cracked, frayed, or glazed; it should be replaced as soon as convenient.

11. When the V-belt tension is correct, tighten the motor hinge bolt, replace the blade, then close both wheel covers.

Shimming Table

To ensure accuracy when cutting stacked workpieces, the table should be 90° to the back of the blade as shown in Figure 61. If the table is not perpendicular to the back of the blade, the table needs to be shimmed.

Shims can be made of any durable object that can be sandwiched between the table and the trunnions. We recommend using shim washers or shim stock because of the wide range of available thicknesses. These items can be purchased at your local hardware store.

Figure 61. Squaring table to blade back.

To shim the table:

1. Make sure that the blade is tracking properly and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Loosen the table mounting bolts that secure the table to the trunnion.
4. Place shims between the table and the trunnion to position the table in the desired direction.
5. Follow the Aligning Table instructions on Page 22 to complete this procedure.

Blade Lead

Bandsaw blades sometimes wander off the cut line when sawing, as shown in Figure 62. This is called blade lead. Blade lead is commonly caused by too fast of a feed rate, a dull or abused blade, or improper tension. If your blade is sharp/undamaged and you still have blade lead, perform the following instructions.

Figure 62. Blade leading away from line of cut.

Correct blade lead

1. Use less pressure when feeding the workpiece through the cut.
2. Check that the miter slot or fence is parallel to the blade line, and correct if necessary.
3. Check for proper blade tension. If the blade tension is correct and it is not convenient to replace the blade, compensate for lead by skewing the fence or adjusting the table.

Skewing your fence

1. Cut a piece of scrap wood approximately 3/4" thick x 3" wide x 17" long. On a wide face of the board, draw a straight line parallel to the long edge.
2. Cut halfway through the board on the line by pushing it into the blade. Turn the bandsaw OFF and wait for the blade to stop.

3. Clamp the board to the bandsaw table without moving it. Now slide the fence over to the board so it barely touches one end of the board.

4. Loosen the four cap screws on top of the fence.

5. Skew the fence so it is parallel to the edge of the scrap piece. You may need to re-adjust the fence locking mechanisms to gain maximum adjustment.

6. While maintaining the skew, tighten the cap screws.

NOTICE

Lead adjustments will change when new blades are mounted on the saw.

Shifting Table

1. On a scrap piece of wood, mark a line that is perpendicular to the front edge.

2. Cut halfway through the board on the line by pushing it into the blade.

3. Turn the bandsaw OFF and wait for the blade to stop.

4. Loosen the table mounting bolts, shift the table to compensate for the blade lead, then retighten the bolts.

5. Repeat Steps 1–4 until the blade cuts straight.

NOTICE

If the table is shifted, the fence will need to be re-aligned, and the blade guides and blade support will need to be re-adjusted.

Wheel Alignment

Components and Hardware Needed: Qty

• 45-1/2" Long 2x4 ........ 1

Tools Needed:

• Wrench 13mm ........ 1
• Tape Measure ........ 1
• Coplanarity Gauge (see Figure 63) ........ 1

Wheel alignment is one of the most critical factors for optimal performance from your bandsaw.

Heat, vibration, wandering, blade wear, tire wear and overall bandsaw wear are considerably decreased when the wheels are properly aligned or "coplanar."

Coplanar wheels automatically track the blade by balancing it on the crown of the wheel. This is known as coplanar tracking.

To check if your wheels are coplanar:

1. Make the "Coplanarity Gauge" shown in Figure 63.

   Note: For best results, straighten the 2x4 with a jointer before cutting.

2. Remove the fence and table, then open both wheel covers.

3. Make sure the guide blocks and rear support bearings are away from the blade, then tighten your blade to the tension that it will be used during operation.

4. Place your coplanarity gauge up against both wheels in the positions shown in Figure 64.

5. The adjustment hub allows you to move the lower wheel tilt vertically and horizontally.

Figure 63. Dimensions of coplanarity gauge.

Figure 64. Checking for coplanarity.

6. Adjust the tracking knob to get both wheels parallel. If the wheels won’t go parallel to each other, then move the lower wheel at the adjustment hub so they line up.

7. If the wheels will go parallel but not coplanar, then move the lower wheel at the adjustment hub (Figure 65) as necessary.

8. Figure 66 shows the positions of the wheels when coplanar. When your wheels are coplanar, readjust the guide blocks and rear support bearings, and replace the wheel covers.

Note: The blade may track slightly OFF center when the wheels are coplanar. This is natural because the blade will be balanced ON the crown of the tire, rather than just in the center of the tire. This will be more noticeable with larger blades.

WARNING

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is connected 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.
