Introduction This manual is provided by JET covering the safe operation and maintenance procedures for a JET Model JSG-6DC Belt/Disc Sander. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown. This machine has been designed and constructed to provide years of trouble free operation if used in accordance with instructions set forth in this manual.
On/Off Switch Padlock The Sander is equipped with a push-button switch that will accept a safety padlock (not included). To safeguard your machine from unauthorized operation and accidental starting by young children, the use of a padlock is highly recommended. To lock out the switch: 1. Open the padlock. See Figure 1. 2. Insert through holes in the start button. 3. Close the padlock. 4. Secure the key in a safe place.
Grounding Instructions Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury. 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 equipment-grounding conductor and a grounding plug.
3. The 115V attachment plug (shown in Figure 6) supplied with the sander, must be replaced with a UL/CSA listed plug suitable for 230V operation (shown in Figure 7). Contact your local authorized JET service center or qualified electrician for proper procedures to install the plug. The sander must comply with all local and national codes after the 230 volt plug is installed. 4. The band saw with a 230 volt plug should only be connected to an outlet having the same configuration (see Figure 7).
Unpacking Open shipping carton(s) and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Sander is assembled and running properly. Compare the contents of your carton(s) with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.
Contents of Closed Stand Carton: (Optional Accessory – p/n 708598) See Figure 9. 1 1 1 Stand Owner’s Manual (not shown) Hardware Bag*, containing: 4 Hex Cap Screws, M10 x 80 8 Flat Washers, M10 4 Lock Washers, M10 4 Hex Nuts, M10 (*Note: The closed stand hardware bag contains the same fasteners as the sander hardware bag, and will not be needed if you purchased sander and stand together.) Figure 9 (Optional Accessory) Contents of Open Stand Carton: (Optional Accessory – p/n 708566) See Figure 10.
Assembly Tools required for assembly: 4mm Hex Key 6mm Hex Key (provided) 13mm open-end wrench (2) 11/16” wrenches or sockets Machine is heavy! Use caution when lifting out of the shipping carton and moving to a final location. Stand or bench must be stable enough to support heavy weight. 1. Use a hoist with straps to remove the Sander from the carton. Prevent straps from contacting any levers or switches while lifting. Figure 11 (closed stand optional) 2.
Note: The trunnion brackets are not identical; make sure the bracket with the raised indicator line is installed on the left side of the table. 4. Install a lock knob (D) on each threaded stud and tighten to hold the table in position. 5. See “Adjustments” section for further instruction on adjusting the disc table. Belt Table 1. Loosen the sanding platen lock screw (E, Figure 13) with a 6mm hex wrench, and tilt the belt arm to a vertical position. Re-tighten the lock screw. Figure 14 2.
4. Rotate disc a half turn and press other half of abrasive into place. Make sure to remove any entrapped air by pressing all parts of the abrasive against the disc. Abrasive Belt 1. Disconnect machine from power source. 2. Raise the belt arm to vertical position. 3. Loosen lock screw and open left side panel. 4. Most brands of replacement abrasives are directional, and must be installed in the proper direction. Directional belts are so indicated on the backing material by arrows.
Dust Collection It is strongly recommended that a dust collection system (not included) be connected to the sander. Mount a 4-inch hose to the sander’s dust port and secure with a hose clamp. (Note: Dryer vent hose is not suitable for such use). The dust collector should have sufficient capacity for this size machine; a minimum rating of 450 CFM (cubic feet per minute) is recommended. A variety of JET dust collectors is available; see our website at www.jettools.com.
Adjust 90° Stop 6. With the table locked at 90°, loosen the hex nut on the 90° stop, and adjust the set screw to seat against the stop block. See Figure 19. Re-tighten hex nut to secure the setting. 7. If angle indicator adjustment is necessary, loosen the screw and shift the pointer to zero, and re-tighten the screw. Adjust 45° Stop 8. Flip the stop block out of the way, and tilt the table down to 45°. Verify the setting of the 45° angle stop (Figure 19).
4. If table is not parallel, loosen the four screws holding the table to the trunnions (B, Figure 25) with a 12mm wrench, and nudge the table until parallel. Re-tighten screws. Note: Always maintain a gap of approximately 1/16” between the table edge and the abrasive disc. Once the table is square and parallel to the disc, verify the stops, as follows: Adjust 90° Stop 5. Loosen lock nut on the 90° stop (Figure 23) with a 10mm wrench. Turn the set screw down (3mm hex key) to contact the table.
Belt Tracking Adjustment The belt should run at the center of the belt arm without veering to the left or right. Check this as follows: 1. Disconnect machine from the power source. 2. Rotate the belt by hand and observe how it tracks. The belt should run centered on the belt wheels. 3. If the belt has a tendency to track left or right of center, loosen locking nuts (A, Figure 28). 4. Turn the front screw (B, Figure 28) while turning the belt by hand and observe belt tracking.
Troubleshooting Trouble Sander will not start. Sanding belt does not come up to speed. Sander vibrates excessively. Abrasive belt keeps tearing. Sanded edge not square. Sanding marks on wood. Probable Cause Remedy Sander unplugged from wall, or motor. Check all plug connections. Fuse blown or circuit breaker tripped. Replace fuse, or reset circuit breaker. Verify that supply circuit is appropriate for amperage rating on motor plate. Cord damaged. Replace cord. Starting capacitor bad.
