",---. -~ Vertical Cutting Plate Assembly I Note: These steps are only necessary if using the bandsaw in the vertical mode. A Fig.2A 1. Disconnect the bandsaw from the power source. 2. Raise the arm to the vertical position by turning A the arm stop (A, Fig, 2A) a quarter turn clockwise, slowing bring the arm to vertical, and lock in place by turning the hydraulic cylinder valve to the off position.
Electrical Connections CURRENT CARRYING PRONGS w e ,~ The HVBS-7MW bandsaw is rated at 115/230Vand comes from the factory prewired at 115V. To switch to 230V operation, follow the wiring diagram found on the inside of the motor junction box. The plug end will have to replaced with a plug that is rated at 230V. The coolant pump wiring will have to be changed also. Follow the diagram found on the cooling pump head to switch to 230V operation.
Prior to Operation 1. Check to see that the blade tooth direction matches the diagram on saw body. 2. Check to see that the blade is properly seated on the wheels after proper tension has been applied. 3. Set the blade guide roller bearings snug against blade. See "Adjusting Blade Guide Bearings" for more detail. 4. Check for a slight clearance between the back up rollers and the back of the blade. 5. Position both blade guides as close to work as possible. 6.
Adjusting the Blade Guides 1. Disconnect the machine from the power source. 2. Loosen knob (A, Fig. 8) and bolt (B, Fig. 8). Slide te blade guide assemblies as close as possible to the the material without interfering with the cut. 3. Tighten knob (A, Fig. 8) and bolt (B, Fig. 8) and connect machine to the power source. Vise Adj ustment .!..) WARNING Fig.8 To set the vise for 0 to 45 degree cutting: 1. Remove the bolt and nut assemblies (C, Fig. 9). 2.
Adjusting Blade Tension Blade tension is important to the proper operation of the saw. Proper blade tension is 22,000 to 25,000 Ibs. per square inch as measured on a blade tension gauge. To set the blade tension without the use of a blade tension gauge: 1. Install the blade between the wheel and insert blade between the bearings on the blade guides. 2. Tension the blade slightly to remove any sag in blade between the blade wheels. 3. Turn the blade tension knob (A, Fig.
Changing Blades 1. Disconnect the machine from the power source. 2. Raise the saw arm to the vertical position and lock in place by turning the hydraulic cylinder off. 3. Remove the red blade guard assembly (A, Fig. 12) by removing two screws (B, Fig.12). 4. Remove the brush assembly (C, Fig. 12) by removing two screws (0, Fig. 12). 5. Loosen blade tension by turning the blade tension knob counter-clockwise. 6. Carefully remove the old blade. Caution: blade teeth are sharp. Handle with care. 7.
9. Turn the blade tension knob clockwise to tension the blade. Do not over tension. See section titled "Adjusting Blade Tension", 10. Close the blade cover door and secure with lock knobs. 11. Attach the red blade guard and brush assembly. 12. Connect the machine to the power source. 13. Run the saw and make sure blade is tracking properly. For a discussion on blade selection, see the enclosed booklet entitled "Lenox Guide to Bandsawing". Adjusting Blade Square to Table ---- 1.
3. If adjustment is necessary, loosen the bolts holding the vice and adjust the vise so that the square lines up properly. Tighten bolts. 4. Connect machine to the power source. Adjusting Blade Tracking Note: Before making any tracking adjustments, try a new blade. Warped blades will not track. Blade tracking has been set at the factory and should not require adjustment. If a tracking problems occurs, adjust the machine as follows: 1.
Adjusting Blade Guide Bearings B 1. Disconnect the machine from the power source. 2. Raise the arm to thevertical positionand lock in place by turning offthe the hydrauliccylinder valve. 3. Loosen the hex cap screw (A,Fig. 16) and adjust assembly so that the back rollerbearing is approximately .003" - .005"from the back of the blade. 4. 5. Turn nut (B, Fig. 16) to adjust the eccentric bearing snug to the blade. Blade should still move up and down freely when grasped as in Fig. 17.
4. Place a fish-type scale under the blade tension handle and lift the saw arm. Scale should indicate approximately 13 - 15 Ibs. 5. Adjust tension to approximately 13 -15 Ibs. by turning bolt (At Fig. 18). 6. Connect the machine to the power source. Adjusting Automatic Shutoff The saw should stop after the cut has been completed: Fig.18 1. If the saw completes the cut and continues to run, adjust the stop tip (A, Fig. 19) down. 2.
5. Place the saw arm in the horizontal position again. Wipe out remaining oil with a rag. 6. Fill the gear box with approximately 3/4 pint of 90 weight gear oil. 7. Replace the gasket and cover. Fasten the cover with screws. 8. Connect machine tTthe power ~ource. Maintenance 1. Keep all surfaces clean and free of rust, slag, chips, and coolant build-up. 2. Do not use compressed air to clean the bandsaw. Compressed air may force chips into the guide bearings and other critical areas of the saw.
