29. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it begins to feed, causing a pinching action between the part and the conveyor bed. Never reach into a running machine. Turn off sander and disconnect from power before attempting to retrieve parts from within the machine.
This manual is provided by WMH Tool Group covering the safe operation and maintenance procedures for a JET Model 16-32 Plus Drum 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.
Features and Terminology The illustration below shows the major components and features of the 16-32 Plus Sander. These are referenced throughout the manual and will help to familiarize you with the operation and functions of the machine. Figure 1...
Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Drum Sander is assembled and running properly. Compare the contents of your boxes with the following parts list to make sure all parts are intact.
Assembling the Stand (Refer to Figure 4. If further clarification is needed, consult the parts breakdown on page 28.) Tools required for Stand assembly: Ratchet wrench with 1/2” socket 1. Assemble legs (H) to outside of Short Rails (L) using carriage bolts (N) and flanged lock nuts (O). Finger tighten only.
(Figure 6). [NOTE:The four holes at the center of the long rails are not used with the 16-32 Plus.] 6. Fasten base to stand (from beneath) with the four screws and flat washers that you removed from the plywood boards.
Infeed/Outfeed Tables (Optional Accessory) The sander should be bolted to the stand or a work table when using these table extensions. Maximum working load of a table is 35 pounds. 1. Install a bracket (A, Figure 8) to the two holes in the sander base with a 9/16”...
2-1/2” hose (see “Optional Accessories” on page 26). Installing Abrasives An 80-grit abrasive strip is already installed on the drum of your sander, and one box of assorted grit Ready to Wrap abrasives is also supplied. Page 25 offers information on the types of abrasive and their recommended uses.

8. You can use your fingers to work the infeed take-up fastener, but it will be more convenient to use the TUFTool supplied with your sander. Hold the TUFTool with the red end pointing away from you (Figure 14) and insert its hook into the outside hole of the fastener lever (see Figure 16).
Repair or replace a damaged or worn cord immediately. As received from the factory, your drum sander is intended for use on a 20 amp, 110V dedicated circuit, which has an outlet and a plug that look like the ones illustrated in Figure 17.
1/16” (or 1/4 turn = approx. 1/64”). Switch Lock Unauthorized use of the sander can be prevented by pulling out the key (Figure 20). Press switch to OFF position before removing the key. When the key is removed, the machine can not be started.
IMPORTANT: The conveyor belt has been over- tensioned for shipping purposes. It must be re- tensioned before operating the sander. Belt Tension: To adjust the tension of the conveyor belt, first adjust the take-up screw nut (Figure 22) on both sides of the conveyor to obtain approximately equal tension on both sides of the belt when taut.
First inspect the alignment with a gauge of some kind. The following procedure uses a steel straight edge as a gauge. 1. Unplug sander from power source. 2. Open the dust cover and remove the abrasive strip from the drum.
Fine-Tuning Drum Alignment (for sanding boards wider than the drum) NOTE: Perform this alignment after you are familiar with sander operation. This is an operational test. When sanding boards wider than the drum, drum alignment is critical and must be exactly level to slightly high on the outboard end to prevent ridges from forming on the board.
(i.e. those set too high, rendering them non-functional) could allow kick-back of pieces being sanded. 1. Unplug sander from power source and remove abrasive from drum. 2. Loosen all four hex nuts on the bearing bolts (A, Figure 29). This will allow both tension rollers to drop to their lowest position.
Tips for Maximum Performance The versatility designed into the 16-32 Plus drum sander allows it to be used for a wide variety of tasks that will boost the return on your investment.
6. On the underside of the conveyor bed, there are U-channels welded to the bed. The Tracker is positioned on the inside of the first U-channel on the infeed side of sander (the U-channel closest to the rubber covered drive roller and gear motor). The back of the Tracker is magnetized and will stick to the side wall of the conveyor bed.
Remedy Check plug connection. Make sure fuse is not blown/circuit breaker is not tripped. Push the circuit breaker button on the sander motor to re-set. Replace switch. Reduce depth of cut; use coarser grit; reduce feed rate. Adjust shaft coupler.

Readjust height control. See pages 18-19. Allow motor to cool and re-set overload button. Connect sander to a dedicated circuit. Have a certified electrician correct any shop wiring problem. Use a shorter or heavier gauge extension cord (see Figure 19).
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. JET Abrasives are available in Ready-To- Wrap pre-cut lengths or in the convenient Ready-To-Cut pre-marked box.
