Always turn the Sander’s ON/OFF Locking Switch (22) to its “OFF” position, remove the Switch Key (21), and unplug the machine from its electrical outlet and before performing any inspection, maintenance, or cleaning. 2. Before each use: Inspect the general condition of the Sander. Check for misalignment or binding of moving parts, loose, cracked or broken parts, damaged Power Cord, and any other condition that may affect its safe operation. If a problem occurs with the Sander, have the problem corrected before further use. Do not use damaged equipment. 3. Before each use: Apply a light coat of paste wax (not included) to the Worktable (35) to make feeding stock easier. 4. After each use: Use compressed air to blow out dust and debris from Sander and its Motor. 5. After each 10 hours of use: Oil the Sleeve Bearings with 30 weight oil. To do so, release the belt tension by sliding the Tension Lever (66) to the right. Move the Sanding Belt (10) slightly to the right or left of the Idler Drum (65) to expose the oval-shaped oiling hole. Apply only two or three drops of oil in the left and right oiling holes. Then, readjust the belt tracking as previously discussed. (See Figure P.) OIL HERE TENSION LEVER (66) IDLER DRUM (65) SLEEVE BEARINGS FIGURE P 6. To replace the timing Drive Belt: A.

Place the Drive Belt (43) around the Drive Pulley (46), then around the other Drive Pulley (49). (See Figure Q.) D. Tighten the three Screws slightly. (See Figure Q.) E. Adjust the tension of the Drive Belt (43) by placing a Standard screwdriver in the adjusting hole and pushing up on the screwdriver to apply tension to the Drive Belt. (See Figure Q.) SKU 38123 For technical questions, please call 1-800-444-3353. Page 17 F. Tighten the three Screws firmly. (See Figure Q.) G.
