Assembling the drill press laser guide，Please watch Youtube video (please turn on English subtitle).
The adjustment method is as follows:
1. Tighten the brake screw and adjust the focus first.
2. Loosen the brake screw and turn the direction of the laser beam to overlap the drill bit.
3. If it cannot be adjusted to fully overlap (skew) the drill bit, the laser beam is not parallel to the drill bit. Then adjust the laser verticality screw to make the laser and drill parallel, repeat items 2 and 3 until the two laser beams must be completely coincident with the axis of the drill.

If the adjustment is correct, no matter whether the drilling machine platform is high or low, the laser intersection is in the correct drilling position.
