The proper drill speed for a given drill bit size is as on following table:
4. Belt Tension Adjustment
For proper belt tension: Use 10 lbs pressure or hand pressure on the belt as shown below. The
distance is 1/2" (13mm) + 10%
5. Quill Spring Adjustment
1. Move the stop nuts to lowest position and lock in place with wrench to prevent quill dropping
while adjusting spring tension.
2. Place screwdriver in lower front notch (A) of spring cap (B) and hold
it in place while loosening and removing nuts.
3. Carefully turn screwdriver counter clockwise and engage next
notch. (Fig. 17)
4. Tighten inner nut (C) with wrench. Do not overtighten as this will
restrict quill movement.
5. Move stop nuts to highest position and check tension while turning
feed handle. If there is not enough tension on spring, repeat steps
2 — 4.
6. Check quill while feeding for smooth and unrestricted movement. If
movement is too tight, loosen nuts slightly.
