Install a wheel (K) and two 5/8”x30 flat washers (L) on each end of the axle. Insert cotter pins (M) through holes on each end of the axle and bend the ends of the cotter pins to secure the wheel on the axle. 7.
When moving the band saw, the cutting head, or “bow”, should be in the down position. 8.0 Assembly of Band Saw Tools required for assembly: 8.2 Pulley Cover and Belt Installation – cross point (Phillips) screwdriver – 3mm and 4mm hex wrenches (provided) – 1/2" and 9/16" wrenches Remove any plastic or holding straps from around the band saw. Areas of the machine have been given a protective coating at the factory. This should be removed using a soft cloth moistened with kerosene or a cleaner-degreaser.
8.3 Stock Stop Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. The stock stop is used for making multiple cuts of the same length. 1. Insert the stock stop rod (A, Figure 5) into the hole at the front of the base as shown. Figure 6 Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
next heavier gauge. The smaller the gauge number, the heavier the cord. The green colored rigid ear, lug or tab, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box, as shown in Figure 7. Recommended Gauges (AWG) of Extension Cords Extension Cord Length * Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.
4. whenever the stop screw is contacting the socket head cap screw (C, Fig 10). 10.4 Positioning the Vise If the vise and blade are square but the pointer (D, Figure 10) is off slightly, loosen the screw and adjust the pointer until it lines up with zero on the scale. Tighten the screw. Keep hands away from blade while adjusting the vise. Refer to Figure 12. Securing the Workpiece Note: The handle (A, Figure 10) is adjustable. Simply lift up on the handle and rotate it on the pin.
Figure 14 10.7 Blade Tracking Figure 13 To change the vise to the 60° position: 1. Disconnect band saw from power source. 2. Raise the bow out of the way. Make sure the hydraulic cylinder is closed (valve lever perpendicular to cylinder) so the bow remains stationary. 3. Remove the two socket head cap screws and lock washers which secure the vise, and lift off the vise. See Figure 13. 4. Move the bushings from the first set of holes to the other set of holes as shown. 5.
10.8 Setting Blade Speed 1. Disconnect band saw from power source. 2. Open the pulley cover. 3. Loosen the knob (see A, Figure 3) and lift up on the motor. Move the belt to the desired pulley grooves. A chart is affixed to the inside of the belt guard showing the positions for the three speeds, 80, 120 and 200 surface feet per minute (SFPM). This chart is also shown in Figure 16. Figure 17 10.
5. The front bearing (E, Figure 18) is eccentric, and should be adjusted so that it just contacts the blade without pinching the blade or interfering with its movement. Proceed as follows: 6. Loosen the hex nut (F, Figure 18) with a 14mm wrench. 7. Use a 12mm wrench to rotate the small hex nut just above the bearing (G, Figure 18) until the bearing is just contacting the blade. 8. Hold the bearing at that position with the wrench on the hex nut, to prevent the bearing from moving.
10.15 Vertical Bow Position 1. 11.0 Operation The band saw can be placed in vertical position to facilitate blade changes, maintenance, etc. Remove the screw (A, Fig. 22) and slide it out to disengage the hydraulic cylinder (B, Fig. 22). Important: This band saw is designed for dry cutting operations only. 11.1 General Operating Procedure 1. Verify that all guards, covers, etc. are in place and in working order, the blade is tensioned properly, and the blade guides are set correctly. 2.
If the power cord is worn, cut, or damaged in any way, have it replaced immediately. 12.0 Maintenance The ball bearings on the blade guide assemblies are self-contained and sealed. They require no further lubrication. 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. Occasionally grease the lead screw on the vise. Clean the machine of chips, shavings, etc.
13.0 Troubleshooting Trouble Motor will not start. Band Saw vibrates excessively. Miter cuts not accurate. Cuts not square. Finished surface of workpiece is rough, unsatisfactory. Probable Cause Remedy No incoming power. Check plug connection. Blown electrical panel fuses. Replace fuses. Defective motor, switch, power cable, or plug. Qualified electrician/service personnel should inspect these items. Stand on uneven surface. Adjust stand for even support. Saw blade has cracks.
