4 Cutting capacity Blade speeds Blade drive Motor Blade guides Blade size Blade wheels Dimensions (L WH) Weight Wet cutting package General Specifications The JET Models J-3410 and J-3410-2 cut-off band saws are designed for high production cut-off work.
5 1. Always wear protective eye wear when operating machinery . Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection.
6 close as possible to the work piece. 9. Always wear protective eye wear when operating, servicing or adjusting machinery . Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.
7 Operating Instructions Using the vise The vise on the saw table has two jaws. The jaw closest to the right hand side of the table is the stationary jaw . This jaw is firmly secured to the table using it s pivot and lock bolts. When making a straight cut the stationary jaw is at right angles to the saw blade.
8 eventually catch the thrust shaft and allow you to open or close the locking jaw at its new lead screw position. When you slide the jaw to a new position, you can see where the nearest lead screw groove is by looking through the slot above the lead screw .
9 Adjusting stationary jaw for high accuracy angle cutting: 1. Raise the saw arm to full height and lock it in position with the shut-off valve. 2. Open the vise to full width. 3. Loosen the pivot and lock bolts shown in Figure 1 . 4. Open the shut-off valve and lower the saw arm until it is at full horizontal position.
10 Controlling the cut: Hydraulic feed control The weight of the saw arm typically provides all of the force needed to move the saw blade through the workpiece. In fact, if the full weight of the arm is allowed to make the cut, rapid blade wear and poor cutting accuracy will result.
11 Changing blade speeds The ModelsJ-3410 and J-3410-2 are 4-speed cut- off saws. The different speeds are obtained by changing the position of the drive V -belt which connects the motor pulley to the drivewheel gearbox pulley . T o change blade speeds: 1.
12 Right angle cuts -- single pieces of stock 1. Raise the saw arm to its full up, open position. 2. Pull up on the quick release handle on the locking vise jaw and slide the vise jaws apart. 3. Place the stock on the saw table, between the vise jaws.
13 Figure 8: Placing workpieces in the vise.
14 Maintenance Replacing blades 1. Disconnect the saw from its electrical power source to prevent accidental start-ups. 2. Raise the saw arm to its full vertical position and lock it in place using the quick shut off valve on the hydraulic control cylinder .
15 Blade alignment adjustments The blade can suffer from several out-of-adjustment conditions. These conditions are shown in Figure 10 . Figure 1 1: Nomenclature for blade guide assembly and its compo.
16 Replacing blade guide and support components All component parts are secured with nuts, bolts, washers, or snap rings. T o remove and replace any component, first remove the blade according to instruc- tions in Replacing blades . Then remove and replace the faulty component(s).
17 Adjusting blade vertical: The blade guide bearing seat can rotate as needed to make the blade vertical to the saw table. Follow these instructions. 1. With the saw arm in horizontal position, put a machinists square on the table, and against the blade, as shown.
18 Adjusting guide bearings There are eight side blade guide/support bearings. These bearings are installed in the bearing seat, and the seat is attached to the sliding adjustment bracket. These bearings are stacked, with two bearings on each adjustment eccentric.
19 Replacing the drive wheel 1. Complete steps 1 through 6 in Replacing blades . 2. Remove the snap ring which secures the lower wheel to the gearbox output shaft. 3. Pull the wheel off of the gearbox output shaft using a suitable puller . 4. Inspection: Examine the wheel for damage on its drive edge, shoulder , or the shaft boss.
20 Servicing the hydraulic control cylinder Over a long period of service the hydraulic control cylinder may need replacement of its internal seals. Use the following procedure.
21 Machine Set-up The saw delivered to you has been adjusted at the factory . A number of test pieces have been cut using the saw to verify the accuracy of cutting. Therefore, the only set-up operations required before releasing the saw for service are spotting the saw and establishing the electrical connections to the motor .
22 Installing the coolant kit 1. Install the baffle in the t ank so the pump is held at one end of the tank. 2. Put the tank and pump assembly in the flanges which hold it in the saw base.
23 T roubleshooting 1. Use more pressure to tighten vise. 2. Check stationary jaw pivot and lock bolts for tightness. 3. Check quick release handle nut for excessive tightness -- nut should be just tight enough to keep adjustable jaw from tilting when tightening.
24 1. Observe chip formation to be sure cutting is efficient. 1. Adjust guide bearings according to instruction in this manual. 1. Increase blade tension so blade does not slip on the wheels. 1. Move guide brackets until they just clear the workpiece while making a complete cut.
