Introduction This manual is provided by Walter Meier (Manufacturing) Inc., covering the safe operation and maintenance procedures for a JET Model 22-44 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 22-44 Plus Sander. These are referenced throughout the manual and will help to familiarize you with the operation and functions of the machine.
Unpacking Open shipping container 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 container 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.
Assembling the Open Stand (Optional Accessory) (Refer to Figure 3. If further clarification is needed, consult the parts breakdown on page 35.) 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).
Assembly Tools required for assembly: 1 1 1 1 Flat head screwdriver Set of open-end wrenches Set of Hex wrenches Adjustable wrench Installing Drum Head The drum sander must be bolted down to a workbench or stand. If you purchased one of the JET stands, place the sander base on the stand and align the holes. Secure the sander to the stand using four 3/8” x 3/4” hex cap screws and four 3/8” flat washers. See Figure 4.
Dust Cover To open the dust cover, push in on the knob (C, Figure 5) and lift. The latch can be adjusted using the screw behind it. Dust Collection Dust collection is mandatory for a safe work environment and extended abrasive life. The 2244 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 500 CFM), as shown in Figure 7.
Successive windings of the strip should be flush with previous windings without any overlap. 5. Mark the trailing end of the strip where it crosses the right (inboard) end of the drum (Figure 11). 6. Remove the abrasive strip from the drum, and cut a taper as was done with the starting edge (see Figure 8). Note: The taper on the remaining roll can be used as the taper for the starting edge of the next strip to be cut. Figure 11 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 17 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.
Conveyor Belt Tension and Tracking Conveyor belt tension adjustment may be necessary during the break-in period to compensate for belt stretching. IMPORTANT: The conveyor belt has been overtensioned for the purpose of shipping. Before operating the sander, adjust the belt tension according to the following instructions! Tension. To adjust the tension of the conveyor belt, first adjust the take-up screw nut (A, Figure 20) using the attached wrench (B, Figure 20).
3. Loosen the conveyor take-up screw nuts (A, Figure 20) to relieve belt tension, and slide the driven roller fully inward. 4. Remove the four bolts that attach the conveyor table to the base. Lift up the conveyor table and remove it from machine. Avoid tearing the belt on any edges underneath the conveyor bed. 5. Install new belt, and re-install conveyor table. Take care not to damage the Trackers. Tension and track the new belt.
5. If the drum does not contact the thickness gauge to the same degree as the opposite end of the drum, alignment is necessary. To align the drum: 1. Loosen the four 3/8” hex cap screws – two front, two rear (A, Figure 22). This allows the entire drum carriage and shroud to be pivoted on two screws – one screw in front, one in back. 2. Lay the thickness gauge under the drum lengthwise. See Figure 23.
NOTE: Keep track of how many revolutions of the fine tune knob are needed to change drum alignment for wider (over 22”) sanding. When sanding narrow stock (less than 22”) loosen the four screws (Figure 22) and turn fine tune adjustment knob counterclockwise the same amount as the initial wide sanding so that drum is again parallel. Tension Roller Alignment The infeed and outfeed rollers are tensioned to provide downward pressure on the workpiece to prevent slippage on the feed conveyor.
Basic Operating Procedure 1. Repeat “Tension Roller Alignment” except raise the sanding drum only 1/4 turn of the height adjustment handle. 1. Set depth of cut. 2. Start dust collection system. 3. Start drum. 4. Start conveyor and select feed rate. 5. Feed stock through machine. To feed stock through the sander, rest and hold the board to be sanded on the conveyor belt, allowing the conveyor belt to carry the board into the drum.
Selecting SandSmart™ Feed Rates decreasing the depth of cut and run the stock through again. A faster feed rate allows faster sanding but fewer revolutions of the drum per inch of sanding. A slower feed rate provides more revolutions of the drum per inch of sanding to allow a greater depth of cut and smooth sanding. Also try a faster feed rate or less depth of cut if the stock you are working begins to show burn marks.
If there is a significant thickness difference, the thinner pieces can slip on the conveyor belt if they do not contact the tension rollers. Also note that pieces thicker than 3/4” should be longer than the minimum normally recommended to prevent tipping of the stock.
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 28. 9. Turn conveyor table right-side up and reposition it onto the sander.
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. 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.
Troubleshooting: Motor and Electrical Problems Trouble Probable Cause Remedy No incoming power. Check plug connections. Connect main cord to power source, and motor cord into control box receptacle. Circuit fuse blown or breaker tripped. Replace fuse or re-set breaker. Switch is malfunctioning. Replace switch. Inadequate circuit. Check electrical requirements. Feed rate too fast or depth of cut too large. Reduce feed rate and/or depth of cut. Motor not properly aligned.
Trouble Conveyor belt tracks to one side, or oscillates from side to side. Abrasive strip is loose. Abrasive loads up prematurely. Table height adjustment works improperly. Knocking sound while running. Probable Cause Remedy Conveyor belt out of adjustment. Readjust conveyor belt; see page 15. Drive or driven roller needs adjusting. Readjust; see page 16. Conveyor belt worn or defective. Replace conveyor belt; see pages 15 and 16. Drive roller worn, bent, or varies in diameter side to side.
Troubleshooting: Operational Problems Trouble Probable Cause Remedy Ripples in sanded surface. Uneven feed rate. Check for these conditions and refer to previous Troubleshooting sections: (Non-uniformly spaced ripples). Conveyor belt slips on drive roller. Board slips on conveyor belt. Conveyor gear motor stalls. Set screw loose on shaft coupler between gear motor and conveyor. Conveyor bushings dry – lubricate. Conveyor bushings worn – replace. Ripples in sanded surface. (Uniformly spaced ripples).
Trouble Probable Cause Remedy Line or groove in stock. Inconsistent feed rate. Do not stop or change the feed rate while feeding stock. Unsanded ridge along length of piece (sandpaper appears clean). Grit has been removed from backing. Avoid this area of drum, or replace abrasive strip.
