33. Always wear leather gloves when handling saw blades. The operator should not wear gloves when operating the machine. 34. Do not allow the saw blade to rest against the workpiece when the saw is not running. 35. The saw must be stopped and the electrical supply must be cut off before any blade replacement, drive belt replacement, or any periodic service or maintenance is performed on the machine. -

Page 8: Unpacking
Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Band Saw is set up and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. -
Page 9: Installation And Assembly
Use a forklift with a strap or chain connected to the eye bolt to lift the band saw from the pallet. Move the band saw to its permanent location which should be dry, well ventilated, with sufficient lighting. -

Extension cords extension 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... -

If the Band Saw is to be hard-wired to a panel, make sure a disconnect is available for the 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. -
Page 12: Blade Tension
If the band saw is not to be used for a period of time, release tension on the blade – this will prolong its life. First make a note of the specific tension setting for that blade. -
Page 13: Guide Post
The stopper positioned behind the back edge of the blade (Figure 10) will also become worn with use, and the friction of the shaft with the saw blade may cause lines in the surface of the stopper. If this occurs, loosen the socket head cap screw, and rotate the stopper to either side to change its position on the blade. -
Page 14: Squaring Work Table With Blade
Squaring Work Table with Blade 1. Place the table in horizontal position with “0” on the scale (Figure 11). 2. Place a machinist’s square on the table and against the blade as shown. 3. If the square is not flush against the blade, loosen the screw below the table (Figure 11) with a 26mm wrench (provided). -
Page 15: Work Lamp Bulb
JET-supplied blades on lower alloy ferrous materials. 1. Use a section of round stock. 2. Operate the saw at low speed. Start the cut with a very light feed rate. 3. When the saw has completed about 1/3 of the cut, increase the feed rate slightly and allow the saw to complete the cut. -
Page 16: Evaluating Cutting Efficiency
Shearing Cut the blade to the longest length needed for the band saw. Using the shear to cut your blade will ensure that the blade ends are cut flat, square and smooth. 1. Place the blade in the shear as shown in Figure 15. -
Page 17: Removing Teeth
IMPORTANT: If a blade has been cut by using snips, the ends of the blade must be ground square before welding them together, as shown in Figure 17. Removing Teeth In fine pitched blades, one or more of the teeth on each side of the cut may need to be removed by grinding so that the weld area of the blade is uniform and the teeth will be uniformly spaced. -
Page 18: Annealing
The size of the radius should be approximately the same as the radius of the band saw drive wheel. The weld must hold and not break or crack after forming the radius. If the weld breaks, cut away the welded area and repeat the welding- annealing process. -
Page 19: Blade Selection
5. the “set” of the teeth 6. the blade material itself Width Band saw width is measured from the back of the blade to the tip of the tooth. Always use the widest blade possible that still performs the needed job. Generally, wider blades are used for straight cutting. -
Page 20: Gage
Gage Use the standard gage (blade thickness) except when the increased thickness of the workpiece decreases accuracy and width cannot be increased to compensate. Examples of heavy gage applications: 1. When radius cutting in thick materials. 2. When the maximum width usable on the machine still provides insufficient beam strength for the blade. -
Page 21: Set
The term “set” refers to the way in which the saw teeth are bent or positioned. Bending the teeth creates a kerf that is wider than the back of the blade. -
Page 22: Maintenance
Maintenance Before doing maintenance on the machine, disconnect it from the electrical supply by pulling out the plug or switching off the main switch! Failure to comply may cause serious injury. Use a brush to loosen accumulated chips and debris. Use a shop vacuum to remove the debris. -
