    ⚠️CAUTION ⚠️ Never try to raise the table with the square beneath the laser head. The table should always be LOWERED , not raised.

    ☠️ WARNING ☠️ Turn off your machine before the next step.

    If the gap is larger toward the top, tilt left.
    If you are unable to tilt the head, loosen the bottom bolt another ½ turn with the Allen key, and repeat.
