4. Mark the laser beam height (center) on the

vertical surface of the wall, as A.

5. Rotate the tool 180°, taking care not to

change its height. The tool should be

positioned with its opposite side facing the

same vertical wall as in step 2. Use the

level (horizontal) Line Dither/Scan position

arrows 23 and 25 to position the laser

beam on the original wall.

6. Mark the height of the laser beam on the

same vertical surface, as B. If B is

positioned at the same height as A,

proceed to step 11. Otherwise, continue to

step 7. The goal of the next few steps is to

position the level laser beam at a height

halfway between A and B

7. Turn off the laser beam and the tool.

Caution: The laser beam must be turned off

and the main power switch in the off position

before proceeding to the next step

8. Insert an Allen wrench into the side

calibration port and locate the calibration

screw. Rotate it clockwise to lower the

beam, or counterclockwise to raise

the beam.

9. Remove the Allen wrench from the

calibration port. Turn on the power, turn on the

level laser beam, then check the height of the

laser beam. Repeat steps 7 and 8 until the

beam is at a height exactly halfway between

A. and B.

Caution: The Allen wrench must be removed

from the calibration port before turning on

the power.

10. Mark this calibrated point on the vertical

surface, as C.

11. Repeat steps 3-7 to confirm the position of

C, then proceed to step 12.

12. Rotate the base unit 90° and position it

with the front facing the vertical surface.

Mark the height of the laser beam, as D.

13. Compare the height of D with C. If the

height of D matches the height of C,

calibration is complete. Turn the power

switch to the off position. Reattach the

calibration port covers, then resume

normal operation. If the height of D does

not match the height of C, proceed to

step 14.

14. Turn off the laser beam and power to the

unit.

Caution: The laser beam must be turned off

and the power switch in the off position before

proceeding to the next step.

15. Insert an Allen wrench into the front

calibration port and locate the calibration

screw. Rotate it clockwise to lower the

beam, or counterclockwise to raise

the beam.
