2) Take a note of the leveling values while repeating the leveling on both X and Z axes until
the overall difference of the leveling falls below 0.02/m.
① To take a note of the leveling values on paper

▪ In the table above, if the right side is 30μ higher, draw a right arrow and type in "30"
in the table. Repeat this for other two positions. From the three values, deduct the
smallest value from the largest, which will be the measurement.
② The measurement may vary depending on your view position due to the distance
between gradation of the level and water bubble tube. So you must read the
gradation vertically at 90 degrees against the level.
8.4 Finishing the leveling
1) If the level measurement falls below the target, perform the static accuracy inspection of
the machine before locking the anchor nut. If you find an error, use the level to correct it.
(refer to "static accuracy inspection and correction" below)
2) When the static accuracy of the machine falls below the specified tolerance, tighten the
anchor nuts starting from the X axis. (The leveling target above is the measurement after
the machine static accuracy inspection)
▪ To tighten the anchor nut
① Tighten the already tightened level bolts by another 1/8 turn (approx. 45˚) before
locking the nuts evenly. (starting from the X axis)
② Inspect the accuracy again and, if an error persists, use the level bolt to correct the
error.
※ If you tightened the bolts evenly at first, the error is not so great if any.
3) Repeat the step above for the Z axis and tighten the anchor nut.
4) While measuring the levels of both X and Z axes again, tighten up the anchor nuts.
