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.
41. Don’t use in dangerous environment. Do not expose machine to rain or use in wet or damp locations. Keep work area well lighted. 29. Keep visitors a safe distance from work area. Keep children away. 30. Make your workshop child proof with padlocks, master switches or by removing starter keys. 42. Make sure band saw is securely fastened to base. 31.

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. 1 1 1 1 1 1 1 1 1 4 4 1 1 1 Figure 5-2: hardware package JWBS14SFX-HPN Stand (not shown) Band saw (not shown) Table – A Table insert (preinstalled in table) – B Handle – C Dust chute – D Fence body – E Resaw fence – F Fence rail – G Rubber feet with hex nut (not shown) Hex wrenches, 2.
5.6 Installing dust chute Disconnect machine power source before installing blade. Mount dust chute (D, Figure 5-3) with four screws (HP4). from Wear gloves when handling blades. New blades are usually packaged in coiled position; to prevent injury uncoil them slowly and carefully while wearing work gloves and safety glasses. 1. Disconnect band saw from power source. 2. Pull table pin (K, Figure 5-5) out of its slot, and remove table insert (B).
9. Reinstall dust block, table insert and table pin. (The table pin prevents deflection of table along blade slot.) 10. Before operating band saw, the new blade must be tensioned and tracked, in that order. Refer to sect. 5.9 and 5.10. 11. The blade guides must also be set properly according to instructions in sect. 7.7 through 7.10. 5.9 Blade tension Refer to Figures 5-7 and 5-8. Figure 5-8 Blade tension should be checked following blade replacement, and periodically as the blade stretches from use.
IMPORTANT: This adjustment is sensitive; perform in small increments and give blade time to react to changes. 8. When blade is tracking near approximate center of wheel, tighten locking handle (J1), and close upper door. 9. Connect saw to power and turn it on to observe blade in action through tracking window. Make further adjustments as needed. 5.11 Blade guides overview Thrust (back support) bearings are located behind saw blade and provide support to back of blade when saw is in operation.
4. Tighten screw (N). 5.15 Aligning table 5. Lower guard plate (M) and tighten in place. The table must be adjusted so that: 6. Make sure all screws and lock knobs on upper guide bearing assembly are tightened when adjustments are complete. 5.14 Lower blade guides Blade teeth are sharp; use care when working near saw blade. 1. Blade runs through center of table insert. Table is aligned with blade. Table is square to blade at 90° scale reading. Disconnect band saw from power source. 2.
. Turn stop screw (HP6) until it contacts saw frame, and tighten hex nut (HP8) against table. 5. If adjustment is needed, use the set screws which are located next to the fence body screws (E3, Figure 5-19). Loosen the four screws (E3) and turn any of the four adjoining set screws in or out as needed, until fence is flat against blade. 6. Tighten screws (E3). 14. If needed, loosen screw and move pointer (M, Figure 5-15) to align with zero on scale. Retighten screw.
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. 14. Tighten the four screws (E3). 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. Disconnect band saw from power; unplug. 2.
5. If miter gauge is not square to blade, loosen handle (A3) and adjust until square. Tighten handle. 6. Verify that pointer (A5) shows 90°. If it does not, loosen screw and shift pointer to 90°. Tighten screw. 7. 7.5.2 Drive belt replacement Disconnect machine from power source before replacing drive belt. If belt becomes worn, cracked, frayed or glazed, it should be replaced as follows: Adjust a stop if needed by loosening hex nut and rotating screw (A6). Retighten nut.
4. 8.0 Operating controls 8.1 Start/stop switch 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. Press green button to start. Press red paddle button to stop. If a power outage occurs, band saw will resume action instantly upon power restoration. If outage occurs, immediately press stop button. 5. 8.1.
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. It is more common with small, narrow blades, and is almost always attributable to poor blade quality, or lack of proper adjustments.
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.
