ADJUST DEPTH STOP – MODELS 4630 AND 4634
1. Turn the adjusting collar until the end of the bit extends 3/32" beyond the
end of the depth stop. Do not push the bit holder in. This will engage the
internal drive.
2. Drive a test fastener in the same material as your workpiece. Examine the
results and make any additional depth stop adjustments:
a) To increase the depth of drive, repeat STEP 1 and turn the adjusting
collar so that the end of the bit extends further than the end of the
depth stop.
b) To decrease depth of drive, repeat STEP 1 and turn the adjusting collar
so that the end of the bit is closer to the end of depth stop. Each click
of the adjusting collar results in a .007" change in the depth of drive.
3. Repeat STEPS 1 and 2 until the desired result is obtained.
