Leave the screwdriver in place. 5. Tighten the (inner) Hex Nut just enough to engage the notch. If this Hex Nut is too tight, it will restrict (up and down) Chuck-Spindle movement. 6. Pull the Feed Knob and check the spring tension, making sure the up movement is smooth and complete. From one inch down, the Chuck should return to its uppermost position. If more tension is required, repeat steps. 7. Replace the (outer) Hex Nut (7) and tighten on top of the (inner) Hex Nut. Do not overtighten. 8. If the (up/down) movement is restricted, slightly loosen the (inner) Hex Nut, and retighten the (outer) Hex Nut. General Maintenance 1. Using compressed air, blow clean the Table, Base, and Motor cooling vents of dirt and materials. 2. Apply paste wax to the Table and Column to enable movement and to help keep surfaces clean. 3. All bearings are factory lubricated and need no further attention. 4. Periodically, lubricate the Tube Column, Table, and Spindle upper teeth with a light oil. 5. Monthly, check the tightness of all mounting screws and bolts in the Base, Column, and Head assemblies. 6. Check belt for wear and replace if frayed or damaged in any way. 7. Lubricate Spindle assembly with a light oil, weekly. 8. Store in a clean and dry location.
