16. the depth of cut is the most IMPORTANT set up procedure before operating as a drum sander It may take some experimentation to determine the proper depth of cut given the variables of abrasive grit type of wood and conveyor feed rate Practicing on scrap before sanding a project can be beneficial A good rule of thumb when sanding is to place the workpiece under the drum and raise the conveyor table so the workpiece contacts the drum but the drum can still be rotated by hand When making successive passes raise the conveyor no more than the thickness of the grit abrasive I e 1 8 1 16 of a turn for 80 grit and less for finer grits Note one revolution of the height adjustment handle moves the table 3 32 DEPTH GAUGE OPERATION The depth gauge see Fig 11 measures the distance between the conveyor table and the bottom of the sanding brush The sanding brush must be parallel to the conveyor bed surface To calibrate the depth gauge loosen the locking knob of the lower depth gauge casting so it rests on top of the table support casting Raise the conveyor table until it touches the sanding brush Then loosen the locking knob of the upper depth gauge casting and position the 0 mark of the scale even with the top of the lower depth gauge casting Lock the upper depth gauge casting in position Once calibrated the locking knob of the lower depth gauge casting can be loosened allowing the lower depth gauge casting to ride on top
17. INGS Replacing the permanently lubricated bearings on the SUPERBRUSH isa relatively straight forward procedure Bearings should be replaced when they allow excessive play of the brush make excessive noise or otherwise indicate failure Note that if clicking noises in the bearings are a problem rotating may be a solution instead of replacement as follows BEARING ROTATING Step 1 Loosen the set screws in the bearing collar Leave the set screw wrench in one of the set screws Then rotate the brush within the bearing and tighten the set screws Fig 19 and 20 Step 2 If the clicking persists or if the brush shaft is tight in the bearing and cannot rotate then loosen the two bolts holding the bearing and the flange for the bearing Now repeat Step 1 After the brush is rotated within the bearing tighten the flanges first and then the set screws After the machine has run for a half hour stop to check that the set screws and bearing bolts are tight Bearing Replacement 1 Disconnect power source to the machine 2 Lower motor to its lowest position using the RPM adjustment handle Then raise motor to its highest position using the RPM adjustment handle This loosens the V belt tension so the V belt can be lifted off the driven pulley 3 Raise conveyor bed until the brush rests on bed If replacing both bearings begin with bearing on the left outboard side Replacing Left Outboard Bearing Make sure power is dis
