Warning 1. Read and understand the entire owner’s manual before attempting assembly or operation. 2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury. 3. Replace the warning labels if they become obscured or removed. 4. This band saw is designed and intended for use by properly trained and experienced personnel only.
20. Make your workshop child proof with padlocks, master switches or by removing starter keys. 21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 22. Maintain a balanced stance at all times so that you do not fall or lean against the blade or other moving parts. Do not overreach or use excessive force to perform any machine operation. 23. Use the right tool at the correct speed and feed rate.
Introduction This manual is provided by JET covering the safe operation and maintenance procedures for a JET Model HBS-814GH Horizontal Band Saw. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown. This machine has been designed and constructed to provide consistent, long-term operation if used in accordance with instructions set forth in this manual.
Contents of the Shipping Container Unpacking 1 2 2 1 4 2 1 1 1 1 1 1 Open shipping container and accessory boxes, 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 assembled and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor.
Installation and Assembly Remove all crating and plastic from around the band saw. Remove any lag screws or holding straps which secure the band saw to the wood pallet. Unpainted areas of the machine have been treated with a rust preventative. This should be removed with a soft cloth and a mild solvent. Do not use paint thinner, lacquer thinner, gasoline or mineral spirits; these will damage painted and plastic surfaces. Do not use an abrasive pad.
Shut-Off Switch Remove the screw and hex nuts which held the bow to the base during shipment. These should be retained in case of future transportation of the Band Saw. The screw below the limit switch, shown in Figure 4, has been pre-set at the factory so that the switch will contact the screw and stop the blade after each cutting operation.
115 Volt Operation As received from the factory, your band saw is ready to operate at 115 volt power, using an outlet and a plug that look similar to those illustrated in Figure 6. A temporary adapter, which looks like the adapter illustrated in Figure 7, may be used to connect this plug to a two-pole receptacle as shown, if a properly grounded outlet is not immediately available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician.
Adjustments Vise There are two sets of holes in the bed to mount the right jaw. The inner hole and slot (A, Figure 10) are used for miter cuts. The outer hole and slot (B, Figure 10) are used for square, or 90° cuts. Figure 10 shows the vise located in the “A” position for miter cuts. Use only position “A” for miter cuts. If the “A” position is used for square cuts, it leaves more blade exposed to the right of the jaw. Figure 10 (fixed jaw shown in “A” position for mitering) Squaring Vise to Blade 1.
5. The quick release function can also be used to back off the movable jaw when the cut is finished. Miter Cuts 1. For miter cuts, move the fixed jaw to the inner holes, or “A” position, as shown in Figure 10. 2. Rotate the fixed jaw to the desired angle, and tighten the center hex nut. NOTE: There is an angle scale on the back side of the bed. This is for reference only. Check angles with a protractor if greater precision is needed. 3.
While performing the following steps, keep the blade from rubbing excessively on the shoulder of the wheel. Excessive rubbing will damage the wheel and/or the blade. 4. Start the saw. Turn the set screw (Figure 14) to tilt the idler wheel until the blade is touching the shoulder of the idler wheel. 5.
Material chips or shavings are the best indicator of proper blade speed and downfeed rate. The ideal chip is thin, tightly curled and warm to the touch. Chips that range from golden brown to black indicate excessive force. Blue chips indicate extreme heat from too high a blade speed, which will shorten blade life. Thin or powdered chips indicate insufficient downfeed rate. Blade Guides Loosen the handle (Figure 17) and slide the guide assembly as close to the workpiece as possible.
Blade Replacement A general-use variable-tooth blade is provided with this metal cutting band saw. Additional blades can be used and are available from your JET distributor. The choice of blade pitch is governed by the thickness of the work to be cut: the thinner the workpiece, the more teeth advised. A minimum of 3 teeth should engage the workpiece at all times. If the teeth of the blade are so far apart that they straddle the work, severe damage to the workpiece and to the blade can result. Figure 19 1.
Operation Figure 22 shows the control panel functions. The Emergency Stop shuts down all functions on the band saw. The machine will not start if the emergency stop is still engaged. To start the machine, twist the emergency stop button until it pops back out. IMPORTANT: When cutting magnesium, never use soluble oils or emulsions (oil-water mix) as water will greatly intensify any accidental magnesium chip fire.
7. Open the valve on the hydraulic cylinder to allow the bow to descend in a gradual and controlled manner. 8. The machine will shut off at the completion of the cut. Turn off the coolant flow, and remove the workpiece. 9. Return the bow to vertical position for the next cut. 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.
Troubleshooting Trouble Probable Cause Remedy Motor will not start. No incoming power. Check plug connection. Blown electrical panel fuses. Replace fuses. Thermal overload has tripped. Wait several minutes for overload to reset itself. Defective motor, switch, power cable, or plug. Qualified electrician/service personnel should inspect these items. Motor is overheating. Check that motor air intakes are clear. Downfeed rate too fast. Reduce downfeed rate. Motor is faulty.
Trouble Probable Cause Remedy Excessive blade breakage. Incorrect blade tension. Adjust accordingly (see page 12). Incorrect blade speed or downfeed rate. Adjust acccordingly. Workpiece loose in vise. Clamp workpiece securely. Blade rubs on wheel shoulder. Adjust blade tracking. Teeth too coarse for material. Use appropriate blade for material being cut. Teeth in contact with workpiece before saw is started. Start motor before blade contacts workpiece. Blade guides are misaligned.
