UNPLUG.THE.DRILL.PRESS!. 2... Open the belt safety cover (see Figure. 19). 3.. Loosen both motor lock knobs at the side of the headstock (see Figure.). 4... Slide the motor away from the headstock until the belt is taut. 5... Hold the motor in position, and tighten the lock screw, and make sure the belt deflection gap is correct when pinched together between the pulleys (see Figure.21). • If the gap between both inner sides of the belt is greater or less than 3.4" repeat Steps.3-5 until the deflection gap is 3.4". • If the deflection gap is 3.4" the belt is tensioned correctly. 6...

UNPLUG.THE.DRILL.PRESS! 2... Wipe off any oil on the spring-lock cover so it will not slip when you hold the cover from spinning (see Figure.22). 3... Make sure the quill is completely seated and the depth stop reads zero. 4.. Put on thick leather gloves, and hold the spring cover against the side of the headstock so the cover stays splined with the locking lug; remove the jam nut and loosen the cover nut approximately 1.4" (6.4mm). 5... Pull the cover outward just enough to disengage the spring-cover lock slot from the locking lug (see Figure.23). 6... Rotate the cover counterclockwise to increase spring tension, or let the cover slowly unwind in the clockwise direction to reduce spring tension (see Figure.23).

Engage the next available spring-cover lock slot with the locking lug and hold the spring lock cover tightly against the side of the headstock (see Figure.24). 8... Snug the cover nut against the spring cover just until the nut stops, and then back- off the nut approximately 1.3 turn, or just enough so there is no binding anywhere along spindle travel path. 9... Hold the cover nut and tighten the jam nut against the cover nut. Quill-Shaft.Screw While you may never have to adjust the quill- shaft screw, you should understand its func tion and know how to adjust it should you ever need to remove the quill for cleaning. This screw prevents the quill from rotating during drilling and sanding procedures, and if adjusted incorrectly, the quill may have lash or bind. To.adjust.the.quill-shaft.screw,.do.these.steps: 1. UNPLUG.THE.DRILL.PRESS!. 2... Clean and lubricate the quill shaft with a thin coat of light oil, so the quill travels freely (see Figure.25). 3... Loosen the jam nut (see Figure.26). 4... Move the quill up and down through the entire range of travel, and turn the quill- shaft screw inward as far as it can go without binding the quill. 5... Tighten the jam nut, and check the quill movement for binding or play while moving the quill up and down through its entire range of travel. 6... Re-adjust the quill-shaft screw as required.

Note: Table or table support parts are not interchangeable between the W1669 and the W1670 drill presses (see Figures.27.and.28). To.adjust.the.table,.do.these.steps: 1... Loosen the table lock lever. 2. Turn the hand crank to raise or lower the table. 3. Tighten the table lock lever. 4. For the W1670, loosen the table tilt lock bolt (see Figure.29); or for the W1669, loosen the cap screw. 5. Turn the index pin draw nut clockwise and draw the index pin out of the casting until you can rotate the table to your desired angle (see Figure.29). Note: Use this index pin only for indexing the table to the “Zero degree” position. Note: To index the table back to the zero position, back off the draw nut, turn the table to zero, tap the index pin back into the casting, and tighten the table tilt lock bolt. 6. Tighten the tilt table lock bolt or cap screw, and double check your angle. Figure.27..W1669Tablesupportassembly. Figure.28..W1670Tablesupportassembly. Figure.29..Tilt mechanism and lock bolt.
