• Before you start, turn on the laser and check that the beam is still on the mark placed on the
wall. If not, reset the laser.

tape on the cradle at the 1000 mm and on the laser line.
• Table base to cradle alignment location is 1005 mm from the center of cradle to the floor.
10.3.4.2 Specifications

level).
• All table adjusters should be preset to 20 mm (3/4 in.) down from the table base to make
adjustment easier. Based on floor levelness and your experience, a different preset height may
work better. One thread must be showing above all locking rings when leveled.
