11. Disconnect tools before servicing; when changing accessories, such as blade, bits, cutters and the like. 12. Direction of feed: Feed work into a blade or cutter against the direction of rotation of the blade or cutter only. 1.0 IMPORTANT SAFETY INSTRUCTIONS 13. Maintain proper adjustment of blade tension, blade guides, and thrust bearings. WARNING – To reduce risk of injury: 1. Read and understand entire owner's manual before attempting assembly or operation. 2.
8. Turn off machine before cleaning. Use a brush or compressed air to remove chips or debris — not your hands. 29. Check damaged parts. Before further use of machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation.

Read and understand the entire contents of this manual before attempting assembly or operation. Failure to comply may cause serious injury. 5.0 Setup and assembly 5.1 Shipping contents See Figures 5-1 and 5-2.
5.6 Installing dust chute Mount dust chute (D, Figure 5-3) with four screws (HP4). Figure 5-4: table and guide rail installation 5. Line up table to trunnion slots and insert screws and washers (HP3/5, Figure 5-5). Only hand tighten screws at this time. Figure 5-3 5.7 Installing and aligning table Refer to Figures 5-4 through 5-6. Figure 5-5: table installation Table is heavy; an assistant is 6. recommended. The table must be mounted so that: • Blade runs through center of table insert.
8. Use a gauge (Figure 5-6) to carefully measure distance from miter slot edge to straight edge. Take measurements at both front and back of table – these should be identical. 9. If miter slot is not parallel to blade, bump table with rubber mallet in the needed direction. 10. When parallelism is achieved (and blade is still centered through table insert), securely tighten the four trunnion screws (HP3, Figure 5-5). 5.7.2 Table-to-blade squaring and 90° stop Figure 5-8 11.
Improper connection of the equipment-grounding 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 equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Before connecting to power source, be sure the switch is in off position.
7.0 Adjustments 7.1 Resaw fence Refer to Figure 7-1. The fence can be installed in one of two positions; vertical (resaw position) or horizontal. Horizontal position is useful for small or thin workpieces, and allows blade guide to be lowered without interference from fence. Zero setting of cursor cannot be used with horizontal fence position. Figure 6-1 6.2 Voltage conversion To convert the JWBS-14SFX from 115V to 230V, single phase operation: 1.
5. Open upper and lower doors by rotating door knobs. 6. Remove dust block (C, Figure 7-4). 7. Carefully remove blade from top wheel, then from between upper and lower blade guides and lower wheel. Slide blade out through slot in table. 8. Guide new blade through table slot. Place blade loosely in upper and lower blade guides. Make sure blade teeth point down toward table, and toward front of saw.
6. 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, raise tension lever to release position – this will prolong the life of blade and tires. Rotate wheel by hand, observing position of blade through tracking window. The blade should ride approximately at center of tire (Figure 7-7). Figure 7-7 7.
7.9 Upper thrust bearing Blade teeth are sharp; use care when working near saw blade. Refer to Figure 7-8. The thrust bearing prevents backward deflection of blade during cutting. 1. Disconnect band saw from power source. 2. Loosen screws (M, Figure 7-8) with 3mm hex wrench and raise guard plate to expose thrust bearing. 3. Loosen screw (N) with 5mm hex wrench, and slide thrust bearing until it almost touches back of blade.
7.12 Drive belt adjustments The drive belt and pulleys are properly adjusted by the manufacturer. However, belt tension should be occasionally checked when the band saw is new, as a new belt may stretch slightly during the breakingin process. 7.12.1 Drive belt tension Check tension by pushing with moderate pressure on belt halfway between pulleys. An adequately tensioned belt will deflect about 1/2-inch. Rotate handwheel (V, Figure 7-4) as needed for proper tension.
gauge for a crosscut, the fence should be moved safely out of the way. 8.0 Operating controls 4. 8.1 Start/stop switch Press green button to start. Press red paddle button to stop. Turn on band saw and allow a few seconds for the machine to reach full speed. 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.
9.3 Crosscutting When resawing thin stock, use a push block, push stick, or similar device to keep your hands away from the blade. Crosscutting is cutting across the grain of the workpiece, while using the miter gauge to feed the workpiece into the blade. 9.5 Blade lead Slide the bar of the miter gauge into the end of the slot on the table. Blade lead, or drift, is when the blade begins to wander off the cutting line even when the band saw fence is being used. Figure 9-5 shows an example of blade lead.
9.7 Width 9.10 Set Band saw blades come in different standard widths, measured from the back of the blade to 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 sect. 9.5). The term "set" refers to the way in which the saw teeth are bent or positioned.
Periodically apply a light coat of paste wax or other non-silicone protectant to the table surface. Select a product that will protect the metal and provide a smooth surface, without staining workpieces. 10.0 User-maintenance Before any intervention on the machine, disconnect it from electrical supply by pulling out the plug. Failure to comply may cause serious injury. If the power cord is worn, cut, or damaged in any way, have it replaced immediately.

12.0 Troubleshooting JWBS-14SFX Band Saw 12.1 Operational problems Table 4 Symptom Probable Cause Correction Table tilt does not hold position under load. Lock handle not tight. Trunnion locking mechanism is broken or worn. Trunnion not lubricated. Trunnion jammed. Tighten lock handle. Replace trunnion locking mechanism. Table will not tilt. Table vibration while sawing. Band saw on uneven floor. Loose fasteners. Drive belt too slack. Incorrect choice of saw blade pitch.
Symptom Blade breaks prematurely. Probable Cause Feed force too great. Blade pitch too coarse. Guide bearings not properly supporting blade. Blade breaks close to weld. Blade tensioned too tightly. Blade overheated during welding. Blade cooled too rapidly after welding. Premature dulling of saw teeth. Blade pitch too fine. Feed pressure too light. Cutting rate too low. Incorrect choice of blade. Chipped tooth or foreign object lodged in cut. 23 Correction Reduce feed force.
12.2 Mechanical and electrical problems Table 5 Symptom Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. Probable Cause No incoming power. Cord damaged. Band Saw frequently trips. Building circuit breaker trips or fuse blows. Switch or motor failure (how to distinguish). Motor overheated. Motor failure. Miswiring of unit. Switch failure. Band Saw does not attain full speed. Extension cord too light or too long. Low current. Motor failure.
