Conveyor belt tension adjustment may be necessary during break in period to compensate for belt stretching If conveyor belt can be stopped by hand pressure applied directly to the top of conveyor bed the belt is too loose Insufficient belt tension will cause slippage of conveyor belt on the drive roller during sanding operation Excessive belt tension can result in bent rollers bent take up brackets and premature conveyor belt wear After the PowerFeed unit has been installed adjust the hex nuts D Fig 2 on both sides of the conveyor to obtain a tight and equally tensioned conveyor belt Use the attached wrench E Fig 2 to adjust the hex nuts Fig 1 Conveyor Belt Tracking Belt tracking adjustment may be necessary during break in period to compensate for belt stretching 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 3 on the side the belt is drifting towards and loosen hex nut on the opposite side Use the attached wrench B Fig 3 to adjust the hex nuts Note Adjustment should be made in 1 4 turns of the hex nut Allow time for the belt to react to the adjustment Do not over adjust Dust Cover To open dust cover push in on the knob C Fig 3 and lift Checking Drum Alignment The sanding drum comes preset from the factory If a problem with drum alignment occ

13. premium quality abrasives such as genuine Performax abrasives will produce a better finish with a less noticeable scratch pattern Note Grits that are too fine can sometimes burnish the wood and leave a glossy surface that will not accept stains evenly This will vary by type of wood Oak for example is susceptible to burnishing because of its open pores Stock Feeding Angle The optimum stock feeding angle when sanding is at a 60 degree angle Fig 13 However even a slight stock feeding angle will provide more effective stock removal less loading of abrasives longer abrasive life potentially faster feed rates and reduced motor loads When finish sanding the workpiece should be fed through in line with the grain on the final one or two passes for the optimum finish Multiple Piece Sanding Runs When abrasive planing or thickness sanding a run of similar pieces that you want to have the same thickness it is best to sand all the pieces at the same time This way you will be able to determine the thickness of the thinnest piece and process all pieces to that same thickness Be aware that the sander will remove cups and crowns in the work piece consider this when measuring the processing stock to the same thickness Edge Sanding When edge sanding the Performax sander will mimic the opposite edge of the stock which is lying on the conveyor belt Because of this it is important for the stock edge to have been ripped

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 Raise fastener lever completely on the inboard end of drum and insert the tapered end of abrasive strip through the slot into the take up fastener Important Position the abrasive strip with sufficient room between the inside of slot and the tapered end of strip to allow it to be pulled into the drum as needed see Figure 11 The abrasive strip may stretch enough in use to allow the take up fastener to reach its lowest position so it no longer is able to maintain tension of the strip If this occurs it will be necessary to reset the take up lever by raising it pushing the strip end into the slot and then releasing the clip lever The Tuf Tool B Fig 12 can also be used to hold the take up fastener in place while you feed the sandpaper through the slot Hold the Tuf Tool at an angle to insert the end into the hole in take up fastener Pull the tool up and rotate 90 to clamp onto the drum see Figure 12 11 Fig 11 52 avms Connecting Sander to a Dust Collector 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 th
