Grounding Instructions

1.75 HP Single Phase Motor

This machine must be

grounded while in use to protect the operator from electric shock.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord immediately.

115 Volt Operation

If your band saw's Stock No. is 710750, it is wired from the factory for 115 volt operation. The power cord has a plug that looks like A, Fig. 1. and is used in an outlet that looks like B, Fig. 1. A temporary adapter with a grounding ear secured with a screw (C, Fig. 1) may be used to connect this plug to a two-pole receptacle if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored grounding ear, lug, or tab, extending from the adapter, must be connected to a permanent

ground such as a properly grounded outlet box, as shown in C, Fig. 1.

Figure 1

230 Volt Operation

If 230V, single phase operation is desired, the following instructions must be followed:

1. Disconnect the machine from the power source.

2. This band saw is supplied with four motor leads that are connected for 115V operation as shown in A, Fig. 2. For 230V operation reconnect the leads as shown in B, Fig. 2.

3. The 115V attachment plug supplied with the band saw (C, Fig. 2) must be replaced with a UL/CSA listed plug suitable for 230V operation (D, Fig. 2). Contact your local Authorized JET Service Center or qualified electrician for proper procedures to install the plug. The band saw must comply with all local and national codes after the 230V plug is installed.

4. The band saw with a 230V plug should only be connected to an outlet having the same configuration (D, Fig. 2). No adapter is available or should be used with the 230V plug.

Important: In all cases (115 or 230 volts), make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.

Grounding Instructions

3 HP Single Phase Motor

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

Make sure the voltage of your power supply matches the specifications on the motor plate of the band saw. The machine should be connected to a dedicated circuit.

operator. During hard-wiring of the band saw, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the band saw will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Extension cords

The use of an extension cord is not recommended for this band saw. But if one is necessary, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Table 1 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Figure 8

Fence Adjustment

5. Place the fence assembly onto the guide rail (D, Fig. 9) and against the edge of the miter slot (C, Fig. 9). The hook at the rear of the

fence should fit under the rear rail (see Figure

12).

The fence must align parallel to the miter slot along the entire length of the fence.

If adjustment is necessary:

6. Lock the fence by pushing down the lock handle (A, Fig. 9). Because the screws are only hand-tight, you can shift the fence slightly as needed until the fence is parallel the miter slot.

7. When the fence has been properly aligned to the miter slot, tighten the four hex cap screws (B, Fig. 9) with a 12mm wrench. Make sure the fence remains parallel to the miter slot as you tighten the screws.

Note: This alignment will again be checked once the guide rail has been tightened.

8. Move the fence assembly to the other side of the blade as shown in Figure 10 so that the

pointer (B, Fig. 10) on the fence body points to zero on the scale. Lock the fence by pushing

the handle (A, Fig. 10) down.

9. Move the guide rail (D, Fig. 10) with the locked fence until the fence is flush against the blade (C, Fig. 10). Do not unlock the fence to perform this. Move the fence and guide rail together when establishing the zero point.

Important: Do not force the fence into the blade so that the blade bends.

Figure 9

10. With a 10mm wrench, tighten the five hex cap screws located on the bottom of the front rail that hold the guide rail to the front rail.

Note: After tightening the guide rail, double check that the fence is still parallel to the miter slot. Make additional adjustments if needed.

Figure 10

Adjusting Clearance between Fence and Table

Referring to Figures 11 and 12:

Check the clearance between the table and the fence. The fence should not rub against the table surface but be slightly above it. This gap should be the same at the front of the table as it is at the rear.

If the gap between fence and table is not consistent, loosen either of the hex nuts on the hook (Figure 12) and rotate the sliding pad until the fence/table gap is consistent across the full length of the table. When this is achieved, tighten both hex nuts.

Check the adjustment of the hook at the rear of the fence. The hook should be positioned so that it overlaps the rear rail by approximately 1/8” (Fig. 12). To adjust the hook, loosen the upper hex nut and slide the hook in or out as needed. Retighten upper hex nut.

Resaw Guide

For resawing attach the post (A, Fig. 13) to the fence with the lock knob (B, Fig. 13). There is a slotted hole in the fence that will accommodate the resaw kit. Position the post so that it is centered with the front edge of the blade. The resaw guide will give you a taller, single point contact surface during resawing.

Figure 11

Figure 12

Miter Gauge

1. Place the miter gauge in the table slot.

2. With a square verify the miter gauge face is square to the blade.

3. If the miter gauge is not square to the blade loosen the lock knob (C, Fig. 13) and adjust to the proper setting. Tighten the lock knob.

2. The gauge (B) indicates the approximate tension according to the width of the blade in inches. Initially, set the blade tension to correspond to the width of your blade.

The JWBS-18X and JWBS-18X-3 come with a 3/4" blade so the tension should be set at 3/4" when using this blade.

Note: The tension gauge can also be seen from the front of the saw through the wheel when the upper door is open.

As you become familiar with the saw, you may find it necessary to change the blade tension from the initial setting.

Keep in mind that too little or too much blade tension can cause blade breakage and/or poor cutting performance.

Tip: When the band saw is not being used, slightly release the tension on the blade – this will prolong the blade’s life. Make a note of the specific tension setting for that particular blade, as shown on the gauge (B). The tension can then be re-set quickly when band saw operations are resumed.

Blade Tracking

Tracking refers to the position of the saw blade on the wheels while the machine is in operation. Tracking has been factory-adjusted. However, it should be checked occasionally, including after every blade change.

Figure 19

through the window (E, Fig. 19). The blade should ride upon the center of the wheel (Figure 20).

2. If the blade tends to move toward the edge of the wheel, loosen the wing nut (D, Fig. 19) and slightly rotate the knob (C, Fig. 19). Rotating the knob clockwise will cause the blade to move toward the rear edge of the wheel. Rotating the knob counterclockwise will cause the blade to move toward the front edge of the wheel.

Note: This adjustment is sensitive; perform it in small increments and give the blade time to react to the changes as you continue to rotate the wheel.

3. When the blade is tracking properly in the center of the wheel, re-tighten the wing nut (D, Fig. 19).

Disconnect machine from

power source before making any adjustments.

Important: The blade must be properly tensioned

before adjusting blade tracking (see previous section). Make sure the blade guides and other parts of the machine will not interfere with the movement of the blade.

To inspect and adjust tracking, proceed as follows:

1. Open upper front door to expose the wheel. Rotate the wheel clockwise by hand and observe the position of the blade on the wheel

4. Close the upper front door.

Figure 20

Overview – Bearing Adjustments

Thrust (back support) bearing are located behind the saw blade and provide support to the back of the blade when the saw is in operation.

Guide bearings are located on either side of the saw blade and provide stability for the blade when the saw is in operation. These bearings rotate on an eccentric shaft so the distance from the blade can be adjusted for optimal performance.

Upper Bearing Adjustments

Unplug the machine from power source before making any adjustments! Blade teeth are sharp - use care when working near the saw blade. Failure to comply may cause serious injury.

Note: Blade tension must be properly adjusted

prior to bearing guide setup. Refer to the Adjusting Blade Tension section.

To adjust the thrust bearing (while referring also to Figure 21):

1. Loosen the thumb screw (E) and slide the

bearing and bearing post until the space between the thrust bearing (H) and the back edge of the blade (G) is approximately 1/64”.

A convenient way to achieve this spacing is by placing a dollar bill folded twice (four thicknesses) between the blade and support bearing – four thicknesses of a dollar bill is approximately 1/64”.

To adjust the guide bearings (refer to Figure 22):

2. Loosen the locking handle (L) and slide the

assembly until the front of the guide bearings rest just behind the gullet of the blade teeth (see inset).

3. Loosen two wing nuts (J

, J2). Rotate the

adjustment handles (M) until the guide bearings (K) rest lightly against the blade (N). Do not force the guide bearings against the side of the blade.

Figure 21

4. Tighten wing nuts (J

, J2 Fig. 22).

Check to make sure the adjustments have not changed and the bearing guides do not pinch the blade.

Figure 22

Lower Bearing Adjustments

Unplug the machine from power source before making any adjustments! Blade teeth are sharp - use care when working near the saw blade. Failure to comply may cause serious injury.

Note: Blade tension must be properly adjusted

prior to bearing guide setup. Refer to the Adjusting Blade Tension section.

Referring to Figure 23:

1. Loosen the thumb screw (B).

This will allow the thrust bearing (A) to move freely and prevent interference with the saw

blade (C) during the following steps.

Guide Gearings Adjustment

2. Loosen the locking handle (D) then turn the

adjustment screw (E) to adjust the assembly

forward or backward until the front of the guide bearings (F) rest just behind the gullet of the blade teeth (C and inset).

3. Tighten the locking handle (D).

Thrust Bearing Adjustment

4. With the thumb screw still loose (from Step 1),

slide the thrust bearing and bearing post until the space between the bearing (A) and the back edge of the blade (C) is approximately 1/64”.

5. Tighten the thumb screw (B).

4. Loosen the lock knob (G). Rotate the

adjustment handles (H) until the guide bearings (F) rest lightly against the blade (C). Do not force the guide bearings against the side of the blade.

5. Tighten the lock knob (G).

Check to make sure the adjustments have not changed and the bearing guides do not pinch the blade.

Figure 23

Blade Lead

Blade drift (also known as lead or fence drift) is a problem that may occur when the blade begins to wander off the cutting line even when the band saw fence is being used. Figure 24 shows an example of blade lead.

Blade lead can be caused by a number of factors, and these should all be checked and corrected if necessary:

 Fence is not parallel to miter slot and

blade.

 Blade is not tensioned correctly.  Blade is dull.  Teeth have too much “set” on one side of

the blade.

If replacement of the blade is not currently an option, the blade lead can be compensated for by skewing the fence. Proceed as follows:

1. Cut a scrap piece of wood about the same

length as the band saw table, and joint one edge along its length, or rip it on a table saw to give it a straight edge.

2. Draw a line on the board parallel with the

jointed, or straight edge of the board.

3. Move the band saw fence out of the way, and

carefully make a freehand cut along your drawn line on the board. Stop about midway on the board, and shut off the band saw (allow the blade to come to a complete stop) but do not allow the board to move.

4. Clamp the board to the table.

5. Slide the band saw fence over against the

board until it contacts the straight edge of the board at some point. Lock the fence down.

6. Loosen the four hex cap screws at the top of

the fence (see Figure 9) and shift the fence until it is parallel to the board along its length.

7. Re-tighten the four hex cap screws.

Note: Skewing the fence to correct blade lead is effective for that particular blade; when a new blade is installed, the fence will probably need readjustment.

Figure 24

Replacing the V-Belt

Disconnect machine from

power source before making any adjustments.

1. Release blade tension as described in the

Blade Tension section.

2. Release belt tension by loosening the two hex

cap screws (A, B, Fig. 25). The pivot bolt (B) is not visible.

3. Raise the motor and place a block of wood

under the motor to take the tension off the belt.

4. Open the lower wheel door (C, Fig. 26) and

remove the hex nut and washer (D, Fig. 26).

5. Remove the wheel (E, Fig. 27). If the lower

wheel does not come off easily you may need to use a pulley puller to remove it.

Note: If you are doing a pulley alignment only, skip Step 6.

6. Remove the old belt (F, Fig. 27) and install the

new belt.

7. Since the wheel is still off, this is the most

convenient time to check the wheel and motor pulley alignment. Jump to the Pulley Alignment procedure (following page) at this time. At the conclusion you will be redirected back here.

Figure 25

8. Reinstall the lower wheel, hex nut and washer

and tighten the hex nut.

9. Remove the wood block or support from below

the motor.

Important: Before operating the band saw, refer to the sections listed below and perform the required adjustments described in them.

Belt Tension

The drive belt and pulleys are properly adjusted at the factory. However, belt tension should be occasionally checked. The belt will need to be retensioned after belt replacement.

Disconnect machine from

power source before making any adjustments.

1. Release belt tension by loosening the two hex

cap screws (A, B, Fig. 25). The pivot bolt (B) is

not visible.

2. Set the belt tension by lightly pressing down on

Figure 26

Figure 27

the motor.

The weight of the motor should put enough tension on the belt. You just want to push down lightly to take up any slack.

3. Tighten the two hex cap screws (A , B).

Note: A new belt may stretch slightly during the “breaking in” process, and the tension may occasionally need to be checked and adjusted.

Pulley Alignment

The pulley alignment is done in conjunction with the V-belt replacement.

If you are just beginning the alignment, start with the Replacing the V-Belt section (previous page.

If you were directed here, proceed as follows:

1. Uses a straight edge placed against the wheel

pulley and motor pulley and refer to Figure 28 to determine if alignment is necessary.

If alignment is necessary:

2. With a 4mm hex wrench, loosen two set screws

on the motor (lower) pulley.

3. Adjust the motor pulley by sliding in or out.

4. Confirm the alignment of the V-belt by placing a

straight edge against the faces of both pulleys, (Figure 28). If the straight edge lies flush against both pulleys, then the pulleys and belt are aligned.

5. Re-tighten the two set screws on the motor

pulley.

6. Return to Step 8 of the Replacing V-Belt

section on page 20.

Electrical Connections

All electrical connections must be done by a qualified electrician. Failure to comply may result in loss of property and/or serious injury.

JWBS-18X is rated at 1.75 HP, 1Ph, 115/230V, prewired 115V.

The band saw comes with a 115V plug (A, Fig. 29). If you switch to 230V a plug needs to be purchased for the band saw that matches the 230V outlet you intend to use.

Figure 28

Confirm power at the site is the same as the saw before making any electrical connections. Review the wiring diagram on page 38.

Review Grounding Instructions on page 7.

Figure 29

Operation

General Procedure

1. Make sure the blade and upper and lower

bearings are properly adjusted for tension and tracking.

2. Adjust blade guide assembly so that the

guide bearings are just above the workpiece (about 3/16”) allowing minimum exposure to the blade. See Figure 30.

3. If using the fence, move it into position and

lock it to the guide rail. If you are using the miter gauge for a crosscut, the fence should be moved safely out of the way.

4. Turn on the band saw and allow a few

seconds for the machine to reach full speed.

Ripping

Ripping is cutting lengthwise down the workpiece, and with the grain (of wood stock). See Figure 31.

Whenever possible, use a

push stick, hold-down, power feeder, jig, or similar device while feeding stock, to prevent your hands getting too close to the blade.

5. Place the straightest edge of the workpiece

against the fence, and push the workpiece slowly into the blade. Do not force the workpiece into the blade.

When cutting, do not

overfeed the blade; overfeeding will reduce blade life, and may cause the blade to break.

6. When cutting long stock, the operator should

use roller stands, support tables, or an assistant to help stabilize the workpiece.

Figure 31

Crosscutting

Crosscutting is cutting across the grain of the workpiece, while using the miter gauge to feed the workpiece into the blade.

Slide the bar of the miter gauge into the end of the slot on the table.

The right hand should hold the workpiece steady against the miter gauge, while the left hand pushes the miter gauge past the blade, as shown in Figure 32.

Do not use the fence in conjunction with the miter gauge. The offcut of the workpiece must not be constrained during or after the cutting process.

Using the fence in

conjunction with the miter gauge can cause binding and possible damage to the blade.

Figure 30

Figure 32

Resawing

Resawing is the process of slicing stock to reduce its thickness, or to produce boards that are thinner than the original workpiece. Figure 33 demonstrates resawing.

The ideal blade for resawing is the widest one the machine can handle, as the wider the blade the better it can hold a straight line.

When resawing thin stock, use a push block, push stick, or similar device to keep your hands away from the blade.

the tip of the tooth. Generally, wider blades are used for ripping or making straight cuts; narrower blades are often used when the part being cut has curves with small radii. When cutting straight lines with a narrow blade, the blade may have a tendency to wander, causing

blade lead. (refer to the Blade Lead section in Adjustments).

Pitch

Pitch is measured in "teeth per inch" (TPI). Figure 34 shows blades with different pitches. A fine pitch (more teeth per inch) will cut slower but smoother. A coarse pitch (fewer teeth per inch) will cut rougher but faster. As a rule of thumb, the thicker the workpiece, the coarser will be the blade pitch. If you have to cut a hard or very brittle material, you will probably want to use a blade with a finer pitch in order to get good clean cuts.

General rule: Use a blade that will have no fewer than 6 and no more than 12 teeth in the workpiece at any given time.

Figure 33

Saw Blade Selection

Using the proper blade for the job will increase the operating efficiency of your band saw, help reduce necessary saw maintenance, and improve your productivity. Thus, it is important to follow certain guidelines when selecting a saw blade.

Here are factors to consider when selecting a blade:

 The type of material you will be cutting.

 The thickness of the workpiece or part.

 The features of the workpiece or part,

such as bends or curves with small radii.

These factors are important because they involve basic concepts of saw blade design. There are five (5) blade features that are normally changed to meet certain kinds of sawing requirements. They are:

1. width

Figure 34

Shape

Figure 35 shows common types of tooth shape. Tooth shape has an effect on cutting rate, and with few exceptions, the Skip and Hook types are used to obtain higher feed rates when cutting thick workpieces. Variable-tooth blades are also available, which combine features of the other styles.

2. pitch (number of teeth per inch),

3. tooth form (or shape),

4. the "set" of the teeth

5. the blade material itself.

Width

Band saw blades come in different standard widths, measured from the back of the blade to

Figure 35

Set

The term "set" refers to the way in which the saw teeth are bent or positioned. Set patterns are usually selected depending on the type of material that needs to be cut. Three common set patterns are shown in Figure 36.

Generally, the Raker set is used for cutting metal workpieces; the Wave set, when the thickness of the workpiece changes, such as cutting hollow tubing or structurals. The Straight set is most often preferred when cutting wood or plastics.

2. Feeding work too fast

3. Using a wide blade to cut a short radius curve

4. Excessive tension

5. Teeth are dull or improperly set

6. Upper guides are set too high off the workpiece

7. Faulty weld on blade

Maintenance

Before any intervention on

the machine, disconnect it from the electrical supply by pulling out the plug. Failure to comply may cause serious injury.

Keep bearing guides clean and free of build-up.

Figure 36

Material

Band saw blades can be made from different types of materials. Some of the most common include spring steel, carbon steel, carbon steel equipped with a high speed or welded edge (bimetal), or carbide tips. A special type of saw blade is made from "high speed steel"; these should not be used on band saws with low rates of speed.

Because of the importance of blade selection, it is recommended that you use the blade selection guide on page 25.

When cutting, do not

overfeed the blade; overfeeding will reduce blade life, and may cause the blade to break.

Blade Breakage

Band saw blades are subject to high stresses and breakage may sometimes be unavoidable. However, many factors can be controlled to help prevent most blade breakage. Here are some common causes for breakage:

1. Misalignment of the blade guides

Check that the cleaning brush over the band wheel is working properly, and remove any deposits from the band wheels to avoid vibration and blade breakage.

The table surface should be kept clean and free of rust for best results. Some users prefer a paste wax coating. Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week; this will fill casting pores and form a moisture barrier. This method provides a table top that is slick and allows rust rings to be easily wiped from the surface. Important also is the fact that talcum powder will not stain wood or mar finishes as wax pickup does.

Do not let saw dust build up in the upper and lower wheel housings. Vacuum out frequently.

Connect the band saw to a JET dust collection system.

Clean and grease the raising/lowering rack for the upper bearing guides if it becomes difficult to raise or lower.

Clean and oil the tensioning mechanism if it becomes difficult to adjust.

Vacuum out the motor fan cover.

Blade Selection Guide

Identify the material and thickness of your workpiece. The chart will show the recommended PITCH, blade TYPE, and FEED RATE.

Key: H – Hook L – Low S – Skip M – Medium R – Regular H – High

Example: 10/H/M means 10 teeth per inch / Hook Type Blade / Medium Feed

Study the part drawing or prototype, or actually measure the smallest cutting radius required, and locate this radius (in inches) on the chart at the right. Follow the curve to where the approximate blade width is specified. If a radius falls between two of the curves, select the widest blade that will saw this radius.

This procedure should be used for making initial blade selections. These recommendations can, of course, be adjusted to meet specific requirements of a cutting job. Compromises may be necessary if you cannot find all needed specifications in a single blade.
