Introduction 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.
Unpacking Open boxes and check for shipping damage. 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. Any missing parts should be reported to your distributor. Read this instruction manual thoroughly for assembly, maintenance and safety instructions.
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. 2. Assemble Long Rail (K) on inside of legs and on top of Short Rails (L). Finger tighten only. NOTE: Flange of Long Rail (K) overlaps flange of Short Rail (L). See Detail 1 below. 3.
Assembling the Sander Tools Required for Assembly (not provided): Ratchet wrench with extension 7/16”, 9/16” and 1/2” sockets 9/16” open-end wrench Flat blade screwdriver Installing Drum Head 1. Lift the drum head assembly out of the box, and temporarily rest it crosswise on top of the stand. (If your stand has casters, make sure they are locked.) Figure 5 The drum head is heavy; use an assistant to help lift if needed. 2. Mount the knob to the height adjustment handle. See Figure 5.
IMPORTANT: The conveyor belt has been overtensioned for shipping purposes. It must be retensioned before operating the sander! See “Conveyor Belt Tension/Tracking” on page 16. 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.
Dust Collection Dust collection is mandatory for a safe work environment and extended abrasive life. The 1632 Plus is equipped with a 4” dust collection port at the top of the dust cover. It is designed to be used with standard 4” dust collection hose connected to a high volume dust collector (minimum 400 to 600 cfm). A standard shop type canister (16 gal. or larger) can be used for short periods of sanding time but requires converting the hose size down to 21/2”.
5. Mark the trailing end of the strip where it crosses the right (inboard) end of the drum (Figure 13). 6. Remove the abrasive strip from the drum, and cut a taper as was done with the starting edge (see Figure 10). Note: The taper on the remaining roll can be used as the taper for the starting edge of the next strip to be cut. 7. Rewrap the drum beginning at the left, as described in steps 2-4 . 8.
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.
Extension Cords Recommended Gauges (AWG) of Extension Cords Extension Cord Length * If an extension cord is necessary, make sure the cord rating is suitable for the amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating. The chart in Figure 19 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
Dust Cover Latch The dust cover latch prevents the dust cover from accidentally opening. To release the latch, press inward on the dust cover knob (D, Figure 21). This will cause the dust cover center to flex and release the latch. Note that the dust cover latch can be adjusted in or out by loosening the screw (E, Figure 21). Conveyor Belt Tension/Tracking Conveyor belt tension and tracking adjustments may occasionally be necessary during break-in and normal operation to compensate for belt stretching.
3. Remove the four bolts attaching conveyor assembly to base. Lift up and slide conveyor out to the side of the machine. 4. Set conveyor on motor side and slide conveyor belt off the end of the conveyor bed. 5. Reverse process for installation of new belt. Sanding Drum Alignment The sanding drum must be aligned parallel to the conveyor bed for proper machine operation. The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, follow the instructions below.
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. Always check this on a piece of scrap wood, as follows, before sanding the work piece. 1.
4. Loosen set screws on collar (Figure 28). 5. Slide collar upward against housing so that all vertical free-play of height adjustment screw is eliminated. An easy method of doing this is to use a block of wood on top of the motor mount slide and under the collar, while lowering the drum with the height adjustment handle. Lubricate around washers beneath handle and above collar.
lower the drum slightly more. However, a combination of several variables will determine the proper depth of cut to use, including the following: 1. Abrasive type and grit size. 2. Width of the piece being processed. 3. Hardness of the piece. 4. Feed rate of the conveyor belt. 1. Repeat “Tension Roller Alignment” except raise the sanding drum only 1/4 turn of the height adjustment handle. 2. If both tension rollers are causing snipe then tighten all four hex nuts (A, Figure 29) at this position. 3.
Multiple-Piece Sanding Runs there is room, angling the stock on the conveyor belt can also help. Slowing the conveyor feed when coming to a rail in the stock can help prevent a dip or gouge. This allows the abrasive to work the wider width with less effort, and to achieve better consistency of the finished surface.
8. Install second Tracker opposite the first. Use both Trackers unless the second one does not fit in conveyor or if conveyor belt is damaged. Tracker Kit (98-0080) Trackers dramatically reduce tracking adjustments of conveyor belts. They are already installed on your sander. The following information is for re-setting or replacing your trackers, should that become necessary. Refer to Figure 32. 9. Turn conveyor bed right side up and reposition the bed onto the base.
Maintenance 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. For best results, perform the following recommended procedures on a monthly basis: • • Lubricate all moving parts, such as threaded rods, washers, and bushings. (Bearings are pre-sealed and require no lubrication.) • Clean sawdust from the abrasive strip and the conveyor belt.
Trouble Probable Cause Remedy Conveyor rollers run intermittently. Shaft coupling loose. Align shaft flats of gear motor and drive roller, and tighten shaft coupling set screws. Abrasive strip is overlapped. Re-wrap abrasive strip (page 12-13) 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. Improper conveyor belt tension.
For fine work, such as furniture, try not to skip any grit grades during the sanding process. In general, premium quality abrasives will produce a better finish with a less noticeable scratch pattern. 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.
