21. 6 6 Use of the Miter Gauge The miter gauge can be used on either the disc or belt surfaces to sand accurate angles on workpieces When using the gauge alone you sand a single angle However by tilting the table and using the miter gauge in combination with the table tilt it is possible to sand compound angles as well When grinding a compound angle you should always check the accuracy of your setup by sanding a piece of scrap material before doing any finish sanding on the actual workpiece 1 Setthe angle you wish to sand using the scale on the miter gauge 2 Tighten the miter gauge securely so the miter reference surface will not move while you are sanding 3 Place the workpiece against the miter reference surface and slide it along the reference surface and into the sanding disc or belt The basic method is shown in Figure 5 below Disc or belt sanding surface Table Miter gauge Hold workpiece against Miter slot miter gauge and slide Workpiece it along the gauge into the sanding surface in direction of large arrow Figure 5 Use of the miter system 7 0 Maintenance 7 1 replacement 1 Disconnect the power to the machine to prevent accidental start ups the machine is plugged into an outlet unplug it the machine is hardwired to a branch circuit with a junction box remove the fuse or trip the circuit breaker to the branch 2 Remove the lock knob and top cover
22. DOES NOT MEAN THE NEW BELT WILL Always check the tracking when replacing a belt 12 To adjust the tracking 12 1 Plug the machine back into the outlet or reestablish power in the branch 12 2 Loosen the tracking lock knob 12 3 Jog the motor on and off as necessary to observe the tracking and turn the tracking knob as necessary to make the belt track in the center of the platen and drums Turn the tracking knob clockwise to move the belt toward the right and counterclockwise to move the belt toward the left 12 4 When the seems to be tracking correctly turn the motor on and leave it running while fine tuning the tracking 12 5 Lock the tracking lock knob 12 6 When the lock knob is secure turn the power off and disconnect the machine from the outlet or branch as in Step 1 above 13 Replace the table side guard top cover and lock knob by reversing steps 3 and 2 above 14 If you have not already done so reconnect the power to the machine and return it to service 7 2 Track mechanism maintenance While the use of a dust collection system can extend service intervals an accumulation of dust will almost certainly require periodic cleaning of the tracking mechanism The more continuous the use of the machine the more frequently this maintenance should be performed As mentioned in the preceding section the need for required maintenance is often indicated by difficulty in adjusting the tension track

Where a plug connection is permitted the following installation practices must be followed 1 The plug used must be a grounding type of plug That is on a 115 volt single phase connection the plug must be a three prong plug with two flat parallel blades for the power wires and a single rounded or U shaped prong for the ground connection On 230 volt single phase connections the lug must be a three prong plug with two flat blades in tandem to carry the current and a third round or U shaped prong for the ground connection 2 The service branch to which the plug is connected must be a branch with a separate ground wire so the grounding prong of the plug can be connected to ground effectively Note Local electrical codes in many jurisdictions DO NOT ALLOW THE USE OF PLUG TYPE CONNECTIONS FOR SINGLE PHASE POWER WHEN THE MACHINE IS USED IN A COMMERCIAL OR INDUSTRIAL ESTABLISHMENT In these cases you must connect your machine to the service branch using a hardwired junction box connection Motor rotation The motor s rotation should result in the belt sander moving downward and the disc sander rotating counterclockwise Voltage conversion Single phase machines are pre wired for 115V or 230V per customer request If it becomes necessary to change the voltage remove the back cover from the base and place the machine on its side Remove the terminal cover from the motor Rewire the motor according to the motor connection diagr
