13. Make all machine adjustments or maintenance with the machine unplugged from the power source. 14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on. 1.0 IMPORTANT SAFETY INSTRUCTIONS 15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after completion of maintenance.
28. Do not stand on the machine. Serious injury could occur if the machine tips over. 35. Don’t use in dangerous environment. Don’t use power tools in damp or wet location, or expose them to rain.

5.0 Features and Terminology The illustration below shows the major components and features of the JWDS-2244OSC Sander. 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 and extension tables. The extension tables are optional accessories 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) A closed stand is provided with the JWDS2244OSCK Sander kit. Refer to 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. Maximum working load of each table is 35 pounds. Fasteners are provided with the extension tables. 6.
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.
3. Begin wrapping abrasive around drum. The tapered edge of strip end should follow as closely as possible to edge of drum. 4. Continue wrapping abrasive in spiral fashion by rotating drum with one hand and guiding strip with the other. See Figure 6-8. 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.
8.0 Adjustments 8.1 Drum Height Control Drum height (i.e. depth of cut) is controlled by height adjustment handle (B, Figure 6-3). Rotate handle clockwise to lower drum, counterclockwise to raise it. One revolution of handle will move drum approximately 1/16” (or 1/4 turn = approx. 1/64”). A scale is fixed below the handle for quick reference. 8.2 Depth scale Figure 7-1 The depth scale indicates distance between bottom of sanding drum and top of conveyor belt.
8.4 Conveyor belt tension/tracking sect. 11.0 Tracker Kit for more information about resetting trackers. Conveyor belt tension adjustment may be necessary during the break-in period to compensate for belt stretching. 8.5 Inspecting drum alignment The sanding drum must be parallel to conveyor table for proper machine operation. The sanding drum comes pre-aligned from the manufacturer. If a problem with drum alignment should occur, follow the instructions below. 8.4.1 Belt tension adjustment 1.
8.5.1 Fine-tuning drum alignment Note: This is an operational test for sanding boards wider than the drum. Perform this procedure only after you have become familiar with sander operation. When sanding boards wider than the drum, table alignment is critical and table must be adjusted exactly level to slightly lower on the outboard end. This will prevent any ridges from developing in the stock. Always check this on a piece of scrap wood, as follows, before sanding the workpiece. 1.
9.3 Basic Operating Procedure Do not start drum while it is contacting workpiece. 1. Establish depth of cut. 2. Start dust collection system. 3. Start sanding drum. 4. Start oscillation and select speed. 5. Start conveyor and select feed rate. 6. Feed stock through machine. To feed stock through the sander, rest and hold board to be sanded on conveyor belt, allowing conveyor to carry board into drum.
If the finish is still affected, make adjustments by slowing the conveyor and/or decreasing the depth of cut and run the stock through again. pieces thicker than 3/4” should be longer than the minimum normally recommended to prevent tipping of the stock. Also try a faster feed rate, faster oscillation or less depth of cut if the stock you are working begins to show burn marks. With cherry, hard maple or other hardwoods, using a shallower depth of cut and a faster feed rate will help minimize burn marks.
10.0 User-maintenance Before doing maintenance on the machine, disconnect it from the electrical supply (pull out the plug), unless indicated otherwise. Failure to comply may cause serious injury. 10.1 Cleaning and lubrication For best results, make cleaning the sander a regular shop procedure.
orientation of brush as you remove it; it should be inserted in the same manner; curvature of brush will match curvature of motor.) 4. Figure 10-3: conveyor belt replacement Note: If conveyor belt continually tracks to one side of the machine, reversing the belt on the conveyor table may remedy the problem. To make sure the conveyor table is not twisted, place a level on the conveyor table. Level the machine if needed.
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-2244OSC Drum Sander 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. fuses blow or circuit breakers trip.
Symptom Possible Cause Correction * Line or groove in stock. Inconsistent feed rate. Snipe marks. Improper tension on rollers. Do not stop or change the feed rate while feeding stock. Re-tension rollers. Sander burns the wood. 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.
