Repair or replace a damaged or worn cord immediately. Model JWBS-18QT Model JWBS-18QT Band Saw has a 1-3/4 HP 1 phase motor and is wired from the factory for 115 volt operation, but can be rewired for 220 volts.
Models JWBS-18-3, -20QT-3, -20QT-5 Recommended Model Voltage Circuit* Band saw models JWBS-18QT-3, JWBS-20QT- 115V JWBS-18QT 3 and JWBS-20QT-5 are wired from the factory 710750B for 230 volt operation. Refer to Specifications for 230V phase and HP ratings. JWBS-18QT-3 710751B A plug is not included. You may either install a JWBS-20QT-3 plug or “hard-wire”...
4. Line up the table (G) to the trunnions so that the bolts (F ) feed through the support bracket (E For band saw model JWBS-18QT Secure the table with two lock knobs (H). For band saw model JWBS-20QT Secure the table with lock knob (H) to bolt F and lock handle (J) to bolt F 5.
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.

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).
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...
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.
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.
Initially, set the blade tension to correspond to the width of your blade. The JWBS-18QT comes with a 3/4" blade so the tension should be set at 3/4" when using this blade.
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.
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.
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.
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.
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).
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.
Operating Controls Safety Key – The magnetic Start/Stop switch Start/Stop Switch comes equipped with a magnetic safety key. The switch shown in Figure 30 is used on model When in position on the switch as shown in JBWS-18QT band saw. Figure 31, the magnetic safety key trips a relay which will allow the machine to start and stop Press the green on button (A, Fig.
Ripping Operation Ripping cutting lengthwise down workpiece, and with the grain (of wood stock). General Procedure See Figure 34. 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.
Resawing the tip of the tooth. Generally, wider blades are used for ripping or making straight cuts; Resawing is the process of slicing stock to narrower blades are often used when the part reduce its thickness, or to produce boards that being cut has curves with small radii.
Blade Do not let saw dust build up in the upper and Selection Guide on page 27. lower wheel housings. Vacuum out frequently. Connect the band saw to a JET dust collection When cutting, system.
