5) to the support rod (D, Fig. 5) by tightening the hex cap screw (E, Fig. 5) against the flat on the support rod. Tighten the jam nut. 18. Raise the table to a good height and tighten two set screws on the bracket. 19. Mount the small bracket between the backside of the extension bracket and the sander using two hex cap bolts, two lock washers and two flat washers. 20. Connect the sander to the power source, turn on the power to the machine just enough to start the belt rotating and then turn off. Do this several times and observe belt tracking. The belt should not wander up or down. It should be centered between the two belt rollers. If adjust is necessary refer to “Belt Tracking Adjustment” pages 11-12. 21. Reinstall the guards and secure in place with lock knobs. 22. Attach the extension cover (D, Fig. 6) with three pan head screws and one lock knob. 9 . WARNING Removing the belt guard exposes more of the sanding belt! Replace the belt guards immediately after completing any sanding that requires it’s removal! Failure to comply may cause serious injury! Horizontal Sanding With the sanding platen locked in the horizontal position, the removable fence (A, Fig. 6) may be used. The fence can be secured in place by screwing two lock knobs (B, Fig. 6) into the guide blocks found in the miter slot. Adjust the table so the fence is at a good height, see “Table Adjustment” page 13.. The backstop (C, Fig. 6) canalsobeusedby removing the extension cover (D, Fig. 6) and placing the backstop pin in the positioning hole and securing in place with the lock knob. The extension cover can be reinstalled. Vertical Sanding With the sanding platen locked in the vertical position, the backstop (A, Fig. 7) and/or the miter gauge (B, Fig. 7) may be used. If you need to do precise 90° work use a square between the table and sanding platen. Adjust for square. Contour Sanding The use of extension table (C, Fig. 7) is optional according to the particular function of the sanding operation. The end guard should always be in place if the extension table is not being used. Sanding Platen Angle Adjustment 1. Disconnect the machine from the power source. 2. Pull handle (A, Fig. 8) forward to release tension. 3. Move sanding platen to desired position and hold while locking handle. 4. Use a combination square between the table and sanding platen to get precise angles. 10 Platen Lock Tension Adjustment 1. Disconnect the machine from the power source. 2. Loosen lock handle by pulling forward (A, Fig. 9) and move motor and sanding table toward the horizontal position. Do not lock. 3. Tension eccentric block by tightening the nyloc nut (B, Fig. 9) with a 14mm wrench. Turn the nut in . turn increments and test locking handle for proper tension. Locking handle is properly tensioned when it requires positive force to move the eccentric block (attached to the locking handle) from one side to the other. The platen and motor assembly must stay in a locked position without sliding once the handle has been moved to the locked position. Re-adjust as necessary. Changing the Sanding Belt 1. Disconnect the machine from the power source. 2. Lock sanding platen in the vertical position. 3. Release tension on the belt by pushing handle (A, Fig. 10) to the left (as the operator faces the machine). 4. Remove belt guards. 5. Carefully remove old belt. Observe direction arrow on inside of sanding belt. Make sure that direction arrow on belt matches direction indicator on the belt cover. Install new belt over both rollers and line up edge of belt with edge of rollers. 6. Tension belt by pushing handle to the right. 7. Reinstall the belt guards Note: Belts stretch with wear. You may have to adjust tracking with a new belt. Belt Tracking Adjustment 1. Disconnect the machine from the power source. 2. Push the belt by hand in the direction indicated on the belt cover. Observe the belt position on the rollers. Edge of belt should remain even with the edge of the rollers. 11 3. Insert the driver with the round shaft, supplied with the machine into the micro adjusting nut (A, Fig. 11) and turn away from you to loosen. 4. Turn the micro adjusting screw (B, Fig. 11) in . turn increments until the belt tracks evenly on the rollers when rotated by hand. 5. Tighten the micro adjusting nut (A, Fig. 11). 6. Connect the machine to power. 7. Turn on the power to the machine just enough to start the belt rotating and then turn off. Do this several times and observe belt tracking. Adjust as necessary. If the tracking cannot be corrected goto the next section “Motor Mount Tracking Adjustment”. Motor Mount Tracking Adjustment The EHVS-80CS comes with tracking adjustment bolts (A, Fig. 12) on the motor plate. These are set at the factory and should not require any further adjustment. If, however, you are not able to track the belt using the belt tracking adjustment assembly on the sanding platen, the motor mount bolts will have to be adjusted: 1. Disconnect the machine from the pow...
