You may either install a plug or “hard-wire” the band saw directly to a control panel.
Unpacking Remove the crate and packing material from the band saw except for the transport skid on the bottom. Inspect the machine for damage. Report any damage to your distributor and shipping agent. Move the saw to its permanent working location. The site should be dry, well lit, and have enough room to handle long stock and the service and/or adjustment of the machine from any side. Move the band saw off the skid. Clean all rust protected surfaces with a mild solvent or diesel fuel and a soft cloth.
Assembly Handwheel Attach the handle (A, Fig. 4) to the handwheel (B, Fig. 4). Figure 4 Mounting the Table Important: The table is heavy. Mounting with the help of another person is recommended. Referring to Figures 5 and 6: 1. Remove the table insert (A) and tapered pin (B). 2. Slide the table so the saw blade (D) passes through the slot where the tapered pin (B) was located. 3.
Rail Assembly Referring to Figure 7: 1. Attach the front rail (F) to the cast iron table with two 1/4” x 5/8” hex cap screws, two 1/4” lock washers, and two 1/4” flat washers. The screws should be in approximately the center of the slot. Hand-tighten only at this time. 2. Attach the rear rail (G) to the table with two 1/4” x 5/8” hex cap screws, two 1/4” lock washers, and two 1/4” flat washers. Screws should be in approximately the center of the slot. Hand-tighten only at this time. 3.
Fence Adjustment 2. 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: 3. Lock the fence by pushing down the lock handle (A, Fig. 9).
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. Figure 11 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.
Adjustments Table Tilt Referring to Figure 14: 1. Disconnect machine from power source. 2. Loosen the lock knob(s)/lock handle (G). 3. Tilt table up to 45 degrees to the right, or up to 10 degrees to the left. 4. Tighten the lock knob(s)/lock handle. Note: Table stop bolt (F, Fig. 14) must be removed to tilt table to the left. Figure 14 Adjusting 90 Degree Table Stop Before adjusting the 90º table stop, the blade tension must be properly adjusted (described in the Blade Tension section).
Installing/Changing Blades Disconnect machine from power source. Blade teeth are sharp, use care when handling the blade. Failure to comply may cause serious injury. 1. Disconnect machine from power source. 2. Place the mode selection lever (J, Fig. 18) in the Full Release (Blade Change) position. Note 1: When changing the position of the mode selection lever, the machine must be turned off. Note 2: The blade tension handwheel (A, Fig.
Blade Tension Blade tension is set with the blade tension handwheel (A, Fig. 19) and is performed following blade replacement and periodically as the blade stretches from use. Disconnect machine from power source before making any adjustments. Referring to Figure 19: 1. Place the mode selection lever (F) in the Full Tension position (see Figure 18). 2. Set the blade tension by rotating the handwheel (A) according to the arrow directions shown in Figure 19.
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.
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 and tracking must be properly adjusted prior to bearing guide setup. Refer to the Blade Tension section (page 16). 1. Place the mode selection lever (J, Fig. 18) in the Full Tension position. Referring to Figure 23: 2. Loosen the thumb screw (B).
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.
Changing the Blade Speed Disconnect machine from power source before making any adjustments. The JWBS-18QT and -20QT band saw has two blade-speed options which is determined by the position of the pulley drive belt. Refer to the Specifications section (page 6) for speed specs. To change the blade speed (while referring to Figure 25): 1. Loosen the lock handle (A) that secures the motor (C). 2. Release belt tension by pulling handle (B) up which raises the motor, then tighten lock handle (A). Figure 25 3.
Replacing the Poly V-Belt Disconnect machine from power source before making any adjustments. 1. Place the mode selection lever (J, Fig. 18) in the Full Release position. Referring to Figure 25: 2. Loosen the lock handle (A) that secures the motor (C). 3. Release belt tension by pulling handle (B) up which raises the motor, then tighten lock handle (A). 4. Open the lower wheel door (C, Fig. 27) and remove the hex nut and washer (D, Fig. 27). 5. Remove the wheel (E, Fig. 28).
Pulley Alignment The pulley alignment is done in conjunction with the poly V-belt replacement. If you are just beginning the alignment, start with the Replacing the Poly 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 29 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.
Operating Controls Safety Key – The magnetic Start/Stop switch comes equipped with a magnetic safety key. When in position on the switch as shown in Figure 31, the magnetic safety key trips a relay which will allow the machine to start and stop when the respective switches are pressed. Being magnetic, the safety key can be removed to make the machine inoperable and can be hidden for safe storage by attaching it underneath the rail or another magnetic surface.
Ripping Operation Ripping is cutting lengthwise down the workpiece, and with the grain (of wood stock). See Figure 34. 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 33. 3. If using the fence, move it into position and lock it to the guide rail.
Resawing 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). Resawing is the process of slicing stock to reduce its thickness, or to produce boards that are thinner than the original workpiece. Figure 36 demonstrates resawing.
Set 2. Feeding work too fast 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 39. 3. Using a wide blade to cut a short radius curve 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.
Blade Selection Guide Identify the material and thickness of your workpiece. The chart will show the recommended PITCH, blade TYPE, and FEED RATE.
Troubleshooting Trouble Saw stops or will not start Does not make accurate 45o or 90o cuts Blade wanders during cut Saw makes unsatisfactory cuts Blade does not come up to speed Saw vibrates excessively Probable Cause Remedy Saw unplugged Check plug connections Fuse blown, or circuit breaker tripped Replace fuse, or reset circuit breaker Cord damaged Replace cord Stop not adjusted correctly Check blade with square and adjust stop Angle pointer not set accurately Check blade with square and
