To adjust the spindle retaining spring on your scheppach DP16SL drill press and resolve issues with spindle return speed, follow these steps: First, lower the drill press table to create more space for the adjustment process. Then, locate the adjustment mechanism on the left side of the drill press. Insert a screwdriver into the front lower notch and hold it in place. Using a flat spanner, remove the outer locknut. Next, carefully loosen the inner locknut until the cut-out is released from the boss. Be aware that the spring is under tension. Now, use a screwdriver to turn the spring cap anti-clockwise until you can press the notch into the boss. With the spindle at its lowest position, hold the spring cap in place and adjust until the spindle moves up and down at your desired speed. Once you're satisfied, retighten the inner locknut. If the spindle return is still not correct, repeat the process. If it's too tight, adjust in the reverse direction. Finally, tighten the outer locknut against the inner locknut, being careful not to over-tighten and restrict the spindle's movement. By following these steps, you can fine-tune the spindle return on your scheppach DP16SL drill press for optimal performance.
