Warnings 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. The bandsaw is designed and intended for use by properly trained and experienced personnel only.
21. Keep visitors a safe distance from the work area. Keep children away. 22. Make your workshop child proof with padlocks, master switches or by removing starter keys. 23. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 24. Maintain a balanced stance at all times so that you do not fall into the blade or other moving parts. Do not overreach or use excessive force to perform any machine operation. 25.
Familiarize yourself with the following safety notices used in this manual: This means that if precautions are not heeded, it may result in minor injury and/or possible machine damage. This means that if precautions are not heeded, it may result in serious injury or possibly even death. Introduction The JET Model J-7015 Horizontal Cut-off Bandsaw is designed for high production cut-off work. Four cutting speeds and a hydraulic feed control allow the efficient cutting of virtually any material.
Machine Features Saw Head Figures 1 and 2 depict the main features of the Model J-7015 Horizontal Cut-Off Bandsaw. The machine consists of a machine base onto which is installed a saw head. The saw head (Figure 2) consists of a drive motor, drive pulleys, gearbox, blade wheels, blade guides and supports, control panel, blade tension/blade tracking mechanism, wire brush, and the saw blade. The drive motor is mounted on a pivoting plate that swings outward to provide V-belt tension.
The mechanism also has adjustment screws that enable the saw blade to “track” evenly on the blade wheels. The adjustment screws change the angle of the driven blade wheel shaft so the wheels are aligned. Tracking adjustments are generally made after the saw blade is changed but may be required periodically due to wear over time. Remove the saw from the shipping skid; discard any hold-down devices.
2. Place a warning placard or tag on the service panel to prevent accidental electrical shock. 3. When installing the motor power cord into a receptacle, make sure the plug is compatible with the receptacle. 4. When using hard-wired connections, connect the wires as shown in the Wiring Data section. 5. Install the fuses or reset the breakers. Check operation of the saw. 4. Loosen the drive motor locking handle. Pivot the motor inward to slacken the belt. 5. Select the speed using the placard on the cover.
4. Keep the hydraulic cylinder needle valve in the same position and begin a second cut on the same or similar workpiece. Blade Selection The cut-off saw is delivered with a saw blade that is adequate for a variety of cut-off jobs on a variety of common materials. A 10-tooth, general-purpose blade is provided as standard equipment with the machine. 5. When the blade has completed about 1/3 of the cut, increase the feed rate.
Evaluating Cutting Efficiency Setting The Vise For Angle Cuts Is the blade cutting efficiently? The best way to determine this is to observe the chips formed by the cutting blade. Referring to Figure 9, the vise can be adjusted through a 45-degree arc as follows: 1. Loosen the lock handle (E) that secures the fixed vise jaw (D). If the chip formation is powdery, then the feed is much too light, or the blade is dull. 2.
Starting the Saw Important: The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the performance of the saw begins to deteriorate, the first item that you should check is the blade. Knock off sharp edge here with file To change the blade, refer to the Changing Blades section on page 18. Never operate without blade covers in place.
Coolant Flow and Nozzle Position Setting the Work Stop Referring to Figure 12: The coolant pump must be submerged before operating to prevent damage to the pump. The work stop is an accessory that is included with the JET J-7015 Bandsaw. It is used to set up the saw for making multiple cuts of the same length. Adjust the coolant flow shut-off valve at the top of the saw head weldment. The flow should be no more than the saw blade can draw into the workpiece by the movement of the blade.
Adjustments Blade Tracking Adjustment Refer to Figures 13 and 14. Blade tracking has been set and tested at the factory. Adjustment is rarely required when the blade is used properly or if the blade is correctly welded. If adjustment is needed: 1. Using the blade tension handwheel (D), make sure the blade is properly tensioned. Note: Blade tensioning is described in the Changing Blades section on page 18). Keep proper tension at all times. 2. Raise the saw head (A) as shown. 3. Open the wheel guards (B). 4.
Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two pieces. Note: You may have to repeat the check with the paper several times before the blade and the shoulder cut the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life. When the paper is cut: 10. Turn the adjustment screws (F) slightly in the counter-clockwise direction.
Blade Guide Bearing Adjustment Referring to Figure 16: Guide bearings and guide inserts are located on either side of the saw blade and provide stability for the blade when the saw is in operation. These bearings rotate on an eccentric shaft so the distance from the blade can be adjusted for optimal performance. Blade guides provide blade support.
1. Clamp vise and mart top of bar stock here Verifying Adjustment Accuracy 2. Cut of a slice of the bar stock Refer also to Figure 18. Rod Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2 inch round bar stock to perform these test cuts, as follows: 1. With the bar stock securely clamped in the vise, make a cut through the bar stock. 2. Mark the top of the bar stock. 3. Move the bar stock about 1/4 inch past the blade so you can begin a second cut. 4.
Maintenance Figure 21 Store the removed blade carefully before proceeding. Changing Blades 6. Slide the new blade into the blade guides (J), then loop the blade (G) around the drive wheels (H) such that the teeth face towards the back and the smooth side faces towards the front. Use leather gloves when changing the saw blade to protect your hands from cuts and scratches. Use protective eye wear that meets ANSI Specification Z87.
Changing the Drive Belt Referring to Figures 22 and 23: Disconnect the cut-off saw from its electrical power source. 1. Set the arm at the full horizontal position. 2. Open the drive belt cover to expose the V-belt and pulleys. 3. Loosen the belt tension adjust knob located in the rear under the motor (see Figure 23 for knob direction). Lift the motor upward to loosen the belt. 4. Remove the worn V-belt. 5.
Cleaning 1. Clean off any preservative on machine surfaces. Upper Wheel Bushing – six to eight drops of oil each week. After cleaning: Pivot Points, Shafts, and Bearing areas – six to eight drops of oil each week. 2. Coat machined surfaces of the cutoff saw with a medium consistency machine oil. Reapply the oil coating at least every six months. 3. Clean up accumulated saw cuttings after use.
Troubleshooting Fault Probable Cause Suggested remedy 1. Material loose in vise. 2. Incorrect speed or feed. 3. Excessive blade breakage 4. 5. 6. 7. 8. 1. 2. 3. 4. Premature blade dulling 1. Clamp work securely. 2. Check Machinist’s Handbook for speed/feed appropriate for the material being cut. Teeth too coarse for material. 3. Check Machinist’s Handbook for recommended blade type. Incorrect blade tension. 4. Adjust blade tension to the point where the blade just does not slip on the wheel.
Troubleshooting Fault Probable Cause Suggested remedy Bad cuts (rough) 1. Blade speed too high for feed pressure. 2. Blade is too coarse. 1. Reduce blade speed and feed pressure. 2. Replace with finer blade. 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.
