OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS A A A Fig. 16 Fig. 17 Fig. 18 STARTING AND STOPPING THE MACHINE The on-off switch (A) Fig. 16 is located on the sander base. To turn the sander “ON”, move the switch to the up position. To turn the sander “OFF”, move the switch to the down position. 12 LOCKING SWITCH IN THE “OFF” POSITION IMPORTANT: When the tool is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock (A) Fig. 17 with a 3/16" diameter shackle. OVERLOAD PROTECTION The motor supplied with your sander is equipped with a reset overload relay button (A) Fig. 18. If the motor shuts off or fails to start because of overloading (sanding too heavy, using a worn sanding belt or disc, using the sander beyond its capacity), or low voltage, turn the switch (A) Fig. 16 to the “OFF” position. Let the motor cool three to five minutes and push the reset button (A) Fig. 18. Start the motor. ADJUSTING TENSION AND TRACKING OF THE BELT IMPORTANT: The machine is shipped without belt tension. Before operating the machine, follow these instructions for adjusting the belt for tension and tracking. DISCONNECT MACHINE FROM POWER SOURCE. 1. Loosen the two lock knobs (A) Fig. 19, and remove the top cover (B). 2. Turn the belt tension lever (C) Fig. 20 counter-clockwise to increase the belt tension. NOTE: The tension lever (C) is spring-loaded and can be repositioned by pulling out the handle, moving it, and letting it spring back into position. Correct tension is determined by: Fig. 19 (A) flatness of the belt on the plate. (B slippage of the belt when sanding heavy work. 3. Rotate the belt (D) Fig. 21 by hand, and tighten or loosen the tracking knob (E) Figs. 20 and 21 until the belt is tracking correctly. 4. Turn the tool on and off to check for proper tracking. If the belt is leading to one side or the other, very gently turn the tracking knob (E) Fig. 20 clockwise to move the belt to the right or counterclockwise to move the belt to the left. 5. A final adjustment can be made with the motor running. THIS ADJUSTMENT SHOULD BE VERY SLIGHT. 6. Replace the top cover that was removed in STEP 1. B A C E Fig. 20 D E Fig. 21 13 NOTE: After a long period of time, adjustments may be necessary to maintain the tension and tracking of the sanding belt. If the belt will not hold its tension, tighten the set screw (G) Fig. 22. If the belt will not hold its tracking, tighten the set screw (F) Fig. 22. Make only small adjustments to these screws. Over-tightening will lock the tension lever and/or the tracking knob. ADJUSTING SANDING BELT TABLE 90 DEGREES TO BELT G F Fig. 22 F A B D C E Fig. 23 Fig. 24 DISCONNECT MACHINE FROM POWER SOURCE. 1. Loosen the table tilting lock handle (A) Fig. 23, move the stop (B) into position, and rotate the table (C) Fig. 24 until the trunnion (D) Fig. 23 contacts the stop (B). Tighten the lock handle (A). NOTE: The lock handle (A) is spring-loaded and can be repositioned by pulling out the handle, moving it, and letting it spring back into position. 2. Place a square (E) Fig. 24 on the table against the belt. See if the table is 90 degrees to the belt. 3. To adjust, loosen the table tilting lock handle (A) Fig. 23. Turn the adjusting screw (F) in or out until table is 90 degrees to the belt. 4. Tighten the lock handle (A) Fig. 23. 5. The adjusting screw (F) Fig. 23 ensures that the belt table can rapidly return to the 90 degree position after the table has been tilted. 6. Adjust the pointer, if necessary. TILTING THE BELT SANDER TABLE DISCONNECT MACHINE FROM POWER SOURCE. The table (A) can be tilted 45 degrees down (Fig. 25). To tilt the table, loosen the lock handle (B), tilt the t...
