Models J-8201 and J-8203 are wood and metal cutting band saws. JET’s Model J-8201VS and J-8203VS 14-inch Variable Speed Band Saws are ideally suited for metal cutting only with an infinitely variable speed range from 116 to 334 SFPM.
- Misuse of this machine can cause serious injury. - For safety, machine must be set up, used and serviced properly. - Read, understand and follow instructions in the Operating Instructions and Parts Manual which was shipped with your machine. When Setting up Machine: - Always avoid using machine in damp or poorly lighted work areas. - Always be sure the machine support is securely anchored to the floor or the work bench. When Using Machine: - Always wear safety glasses with side shields (See ANSI Z87.
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. A guard or other part that is damaged should be properly repaired or replaced. 20. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter only. 21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF.
Safety Instructions on Sawing Systems 1. Always wear leather gloves when handling saw blade. The operator shall not wear gloves when operating the machine. 2. All doors shall be closed, all panels replaced, and other safety guards in place prior to the machine being started or operated. 3. Be sure that the blade is not in contact with the workpiece when the motor is started.
Introduction Setup and Operation This manual includes operating and maintenance instructions for the JET14-Inch Vertical Band Saws, Models J-8201, J-8203, J-8201VS, and J-8203VS. This manual also includes parts listings and illustrations of replaceable parts. Set-up Band Saw Features Assembly of Band Saw Refer to Figures 1 through 3 for key features of the band saw machine. Refer to the Specifications section for additional information on the features and capabilities of the saw.
6. Tension the belts (refer to Changing Drive Belt Position). 7. Check gearbox fluid level in sight gauge. If required, add lubricant to bring level halfway up the sight gauge. (Two containers of Shell Spirax 90 HD gear oil are packed with the saw. The containers have sufficient amount of lubricant to fill the gearbox.) 8. Check blade tension and support mechanism adjustment (refer to Changing Saw Blades). 9. Plug the motor cable into the switch box on the saw frame.
GROUNDING INSTRUCTIONS 1. All grounded, cord-connected tools: In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Installing Optional Frame Riser NOTE: Refer to the illustrations in the Replacement Parts section for location of the parts used on the frame riser. 1. Remove the saw blade (refer to Changing Saw Blades). 2. Remove the two screws at the top and bottom of the blade guide that holds the blade guide on the frame. WARNING: The saw must be turned off and power disconnected any time the rubber protectors are being changed. 12 3. Unplug the electrical cord or open the circuit breaker in the branch circuit. 4.
Operating Instructions Operating Controls START/STOP Switch The START/STOP switch (refer to Figure 5) is used to turn on the band saw drive motor. The START switch has a molded guard which prevent inadvertent pressing of the START pushbutton. START/STOP Switch Guarded START Switch E-Stop Figure 5. START/STOP Controls The STOP pushbutton is not guarded to allow use as an E-stop in an emergency.
Adjustments Adjusting Blade Support/Guide Height The upper blade support and guide mechanism can be adjusted to accomodate the height of the work piece. 1. To adjust the support, loosen the knob that clamps the support rod, then move the support up or down in its holder. (Refer to Figure location of the support mechanism. 2. Adjust the support so there is space between the support and work piece. Space of approximately 1/8-inch is generally appropriate.

(A damaged or worn blade may provide a poor reference surface for squaring the table.) Loosen the table lock knobs and hold the table firmly against its positive leveling stop. Using a machinist’s square, check to make sure the table is 90 degrees to the blade.
1. Turn the main switch to off. 2. Pull the door open on the pulley case. 3. Turn the clutch handle clockwise and push in, to engage the high speed pulley drive. Or, turn the clutch handle clockwise, and pull out, to engage the reduction gearbox drive. 5. Release the weight of motor so the motor pivots downward. The weight of the motor is provide adequate belt tension. 6. Plug the electrical cord into the power source or close the circuit breaker on the branch circuit.
10. Install the belts as required (refer to Figure 10). 11. Release the weight of motor so the motor pivots downward. The weight of the motor will provide adequate belt tension. 12. The weight of the motor should provide sufficient tension so the the middle of the small drive belt is displaced approximately the thickness of the belt. (The high speed belt is adjusted at the same time as the smaller belt.) 13. Set the drive clutch to the desired position (IN or OUT). 14. Close the access doors. 15.
9. USING LEATHER GLOVES AND ANSI Z87.1 EYEWEAR TO PROTECT YOURSELF FROM THE CUTTING BLADE, carefully remove the blade from the drive wheels. Remove the blade out of the saw table through the table. 10. Hang the removed blade in a safe place.

Lower Blade Support Assembly Replacing drive wheel rubber protectors The rubber rings that cover the drive wheels are called protectors.
Periodic Maintenance Item Action Interval Maintenance Saw blade Listen for sound of missing teeth Observe cutting action for cleanness and accuracy Listen for a poor weld — a “click” as it passes through the guide blocks Watch for signs of slippage on the drive wheels (blade occasionally slows or comes to a stop while sawing) Check bearing area for leakage of lubricant Check bearing area for leakage of lubricant Check for cleanliness Whenever operating saw Whenever operating saw Replace blade when te
Troubleshooting Fault Probable cause Suggested remedy Excessive blade breakage 1. Material loose in vise. 2. Incorrect speed or feed. 1. Clamp work securely. 2. Refer to Figure 6 or check Machinist’s Handbook for speed/ feed appropriate for the material being cut. 3. Check Machinist’s Handbook for recommended blade type. 4. Adjust blade tension to the point where the blade just does not slip on the wheel. 5. Start the motor before placing the saw on the workpiece. 6. Adjust blade tracking. 7.
Troubleshooting (Continued) Blade is twisting 1. Blade is binding in the cut. 2. Blade tension too high. 1. Decrease feed pressure. 2. Decrease tension on blade Unusual wear on side/back of blade 1. Blade guides worn 2. Blade guide bearings not adjusted. 3. Blade guide bearing bracket is loose. 1. Replace blade guides. 2. Adjust blade guide bearings. 1. Blade tooth pitch too coarse for workpiece. 2. Feed too slow; feed too fast. 1. Use blade with finer tooth pitch.
