5.0 Features and Terminology The illustration below shows the major components and features of the JWDS-2244/2550 Sanders. These are referenced throughout the manual and will help to familiarize you with the operation and functions of the machine.
Read and understand the entire contents of this manual before attempting setup or operation! Failure to comply may cause serious injury. NOTE: Figures in this manual may show Sander with stand, extension tables and/or depth stop assembly. These are optional accessories depending upon your model, and are purchased separately. 6.0 Setup and assembly Open boxes and check for shipping damage. Report any damage immediately to your distributor and shipping agent.
Figure 6-3: Assembly of Sander and OPTIONAL Infeed/Outfeed Tables 6.3 Assembling stand 6.6 Folding infeed/outfeed tables (OPTIONAL) An open stand is provided standard with the JWDS2244 Sander. An open or closed stand is available as an optional accessory (separate purchase) for the JWDS-2550 Sander. Refer to the assembly instructions that accompany the stand. See Figure 6-3. The sander must be bolted to the stand or a work table when using these table extensions.
Align infeed table with sander’s conveyor table as follows. See Figures 6-3 and 6-4. 6. Place a straight-edge at one side of conveyor table under drum and extending out over infeed table. See Figure 6-4. You may wish to lower drum until it contacts the straight edge to hold it in place. 7. Raise infeed table until it evenly contacts straight edge. If needed, loosen four screws (HP4) beneath table and adjust table to level. Tighten screws. 8.
2. Release fastener lever to secure end of strip. 3. Begin wrapping abrasive around drum. The tapered edge of strip end should follow as closely as possible to edge of drum. 4. sander comes with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in Figure 7-1. Before connecting to power source, be sure switch is in off position. Continue wrapping abrasive in spiral fashion by rotating drum with one hand and guiding strip with the other. See Figure 6-8.
8.0 Adjustments 8.1 Drum Height Control Drum height and depth of cut are controlled by height adjustment handle (B, Figure 6-3). Rotating handle clockwise lowers drum, counterclockwise raises it. One revolution of handle will move drum approximately 1/16” (or 1/4 turn = approx. 1/64”), as shown on label below handle. 8.2 Depth scale Figure 7-1 The depth scale indicates distance between bottom of sanding drum and top of conveyor belt. Adjustment is performed by “zeroing” the scale. 1.
Excessive belt tension can result in bent rollers, bent brackets, and/or premature wearing of bushings or conveyor belt. Figure 8-3: belt take-up screw 8.5.2 Belt tracking adjustment A belt tracks correctly when it moves centrally on the conveyor rollers without drifting to either side. Tracking adjustments are made while conveyor belt is running. Figure 8-1 8.
2. Open dust cover and remove abrasive strip from drum. 3. Insert gauge (A, Figure 8-4) between drum and conveyor table at outboard side. lower table at outboard end slightly by turning knob (C). 4. Repeat this process until the ridge is eliminated and entire board is sanded. Note: When sanding narrow stock (less than 16”), return conveyor table to parallel position. Turn knob opposite direction until lock nut (D, Figure 8-4) is contacted. The lock nut provides a positive stop for table parallelism.
9.0 Operations and familiarity with the machine before doing finish work. Before using the drum sander, review the previous sections on initial set-up and adjustment. Before operating, make sure an abrasive strip is mounted and a proper dust collection system is connected. A combination of several variables will determine proper depth of cut to use, including the following: 1. Abrasive type and grit size. 2. Width of piece being processed. 3. Hardness of piece. 4. Feed rate of conveyor belt.
adjustments to fit the job at hand. Following is a list of useful tips which can help you improve performance of your sander. depend on a number of factors, including type of stock, grit and depth of cut used, and whether the stock is fed directly in line with the conveyor table or at an angle. If the drum motor is lugging down, if conveyor belt is slipping, or if you observe a ripple effect on the stock, slow the feed rate.
9.6.6 Face frames and raised panel doors Lubricate conveyor bushings as needed, and check for wear. It is very important to have the proper abrasive contact when doing this type of sanding. If the machine is set to take an excessive depth of cut, the result can be a gouge or dip as the drum goes from sanding the rails at full width to sanding just a few inches of width on the stiles.
10.3 Conveyor belt replacement 10.4 Commutator brush inspection 1. Disconnect sander from power source/unplug. 2. Raise drum to highest position. 3. Remove infeed/outfeed tables, if installed. 4. Turn take-up screws (see Figure 8-3) on both sides of conveyor to relieve belt tension, and slide the driven roller fully inward. To maintain motor efficiency, inspect the two carbon brushes every two months, or more frequently if sander is heavily used.
11.0 Tracker kit 8. Install second tracker opposite the first. Use both trackers unless the second one does not fit in conveyor or unless conveyor belt is damaged. 9. Turn conveyor table right-side up and reposition it onto sander. Re-attach three mounting screws and tighten. Caution: Be careful not to knock tracker(s) out of conveyor table when turning conveyor over. Trackers may break if allowed to fall. Stock No.: PM2244-213 Trackers dramatically reduce tracking adjustments of conveyor belts.
Note: Grits that are too fine can sometimes burnish the wood and leave a glossy surface which will not accept stains evenly. This will vary by type of wood. Oak, for example, is susceptible to burnishing because of its open pores. 12.0 Abrasives The abrasive material you choose will have a substantial effect on the performance of your sander. Variations in paper type, weight, coating and durability all contribute to achieving your desired finish. 12.
13.0 Troubleshooting JWDS-2244,-2550 Drum Sanders Symptom Possible Cause Correction * Drum motor won’t start No incoming current. when switch is activated. Safety key missing from switch. Install safety key. Low voltage. Check power line for proper voltage. Open circuit in motor or loose connection. Switch malfunction. Inspect all lead connections on motor for loose or open connections. Replace switch. Drum motor will not start: Short circuit in line cord or plug.
Symptom Sander burns wood. Board slips on conveyor belt. Possible Cause Correction * Abrasive strip is overlapped. Re-wrap abrasive strip. Abrasive is loaded. Clean abrasive. Depth of cut excessive for fine grit. Use coarser grit or reduce depth of cut. Feed rate too slow. Increase feed rate. Abrasive is worn. Replace abrasive. Tension rollers too high. Lower tension rollers. (optional) extension tables too high. Adjust tables. Excessive feed rate. Reduce feed rate.
