WARNING Wear eye protection. Always keep guards in place and in proper operating condition. Do not operate the machine without the guards for any reason. This sander is intended to be used with wood and wood products only. Use of this sander and a dust collector with metal products is a potential fire hazard. Support the workpiece adequately at all times during operation; maintain control of the work at all times.
• ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE SERVICING. • REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position before plugging in. • USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by JET may cause hazards or risk of injury to persons. • NEVER STAND ON A MACHINE. Serious injury could occur if the machine is tipped. • CHECK DAMAGED PARTS.
Grounding Instructions Caution: This tool must be grounded while in use to protect the operator from electric shock. 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. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Assembly and Setup If you purchased the optional Performax 22-44 Plus Stand refer its assembly instructions before proceeding with the drum and conveyor assembly. 1. Attach the knob (A, Fig. 1) to the handwheel and tighten with a 9/16” wrench. 2. Place the conveyor upside down on a table surface. 3. Raise the drum by turning handwheel (B, Fig. 2) clockwise. 4. Align four holes in the conveyor with the four holes in the base of drum assembly. 5.
Conveyor Belt Tracking outboard end of drum, and counterclockwise to lower outboard end of drum. Belt tracking adjustment may be necessary during break-in period to compensate for belt stretching. 4. When drum is parallel to the conveyor tighten the four hex cap bolts. Abrasive belt tension must be properly adjusted before adjusting the tracking. Adjust the belt tracking while conveyor belt is running at its fastest speed. Tighten hex nut (A, Fig.
Fine Tuning Drum Alignment When sanding boards wider then the drum, drum alignment is critical and must be adjusted exactly level to slightly high on the outboard end. This should prevent any ridges from developing in the stock. Always test on scrap wood before sanding workpiece. Run a piece of scrap wood approximately 6” wide by 30” - 40“ through the sander sideways so that the end of board extends past the end of drum.
5. Wrap abrasive strip around the drum, being careful not to overlap the windings, see Figure 9. 6. Mark trailing end of strip where it crosses the inboard end of drum (A, Fig. 10). 7. Remove the abrasive strip and cut a taper as was done with the starting edge, see Figure 7. Note: The taper on the remaining roll can be used as the taper for the starting edge of the next strip to be cut. 8. Rewrap the drum starting at the left side as described in steps 3-5 on the previous page. 9.
Connecting Sander to a Dust Collector Establishing the Proper Drum Height Dust collection is necessary for all drum sanders. The Performax 22-44 Plus is equipped with a 4” dust collection port at the top of the dust cover, and is designed to be used with a standard dust collector, see Figure 13. To establish the proper drum height, place the board to be sanded under the drum and lower the drum to the board thickness. Note: Sanding drum should still rotate by hand.
to be removed. Then progressively work toward finer grits. The chart below shows the general uses for the various grits. Performax offers strip rolls in the eight different abrasive grits shown. Selecting SANDSMART™ Feed Rates Begin experimenting with the feed rate set at about 40%-50% of maximum. The best feed rate will depend on a number of factors, including type of stock, grit and depth of cut used, and whether the stock is feed directly inline with the conveyor bed or at an angle.
at the proper angle to the face before the sanding process. When edge sanding stock that is less than 3/4” wide, or more than 2” high, it is good procedure to stack and clamp several pieces together to prevent them from slipping, or tipping. Selecting Abrasive Grits The amount of stock to be removed is a major consideration when choosing the grit grade to start with. Grits of 24, 36, 50, 60 and 80 are primarily designed for stock removal.
Cleaning Abrasive Strips A sandpaper cleaning stick may be used to remove deposits and help extend sandpaper life. To use, operate the sanding drum with the dust cover open. Caution: For your own safety, always wear eye protection while performing sandpaper cleaning, and take all precautions to avoid any contact of hands, or clothing with uncovered drums. Hold the cleaning stick against the rotating drum and move it along the drum surface.
2. Thoroughly lubricate the mating surfaces and height adjustment screw. Conveyor Belt Replacement To replace the conveyor belt: 1. Disconnect the machine from the power source. Unplug motor cord from control box. 2. Raise drum to highest position using the handwheel (A, Fig. 16). 3. Remove the belt tension by loosening the take-up nuts (B, Fig. 16). 4. Unscrew the four socket head cap screws (C, Fig. 16) that attach the conveyor and remove the conveyor from the bed. 5.
Troubleshooting Guide Problem Conveyor belt does not move. Possible Cause Solution Shaft coupler not attached. Attach shaft coupler. Conveyor rollers run intermittently. Shaft coupling loose. Abrasive Strip Comes off Drum. 1. Slack in abrasive strip on drum. 2. Abrasive improperly wrapped. Abrasive Strip Loose. Abrasive Loads up Prematurely. Line or Groove in Stock. Wood Burns. Board slips on conveyor belt. Sander motors slow or stall 1.
