Level Calibration Check (Y-Axis); Protecting The Environment - DeWalt DCE074R Manual Del Usuario

4. Mark and measure points A and B on the walls as shown in
Figure O.
5. Turn the entire laser unit 180º so the X-axis points directly
toward the opposite wall.
6. Allow the laser unit to self-level, and mark and measure
points AA and BB on the walls as shown in Figure P.
7. Calculate the total error using the equation:
Total Error = (aa – a) – (BB– B)
8. Compare total error to the allowable limits shown in the
following table.
Distance between walls
L = 15 m
L = 25 m
L = 50 m

Level Calibration Check (Y-axis)

Repeat the procedure above, but with the laser unit positioned
so the Y-axis is pointed directly toward the walls.
Plumb Error Check (Fig. Q)
1. Using a standard plumb bob as a reference, mark the top
and bottom of a wall. (Be sure to mark the wall and not the
floor and ceiling.)
2. Position the rotary laser securely on the floor approximately
1 m from the wall.

3. Turn the laser on, and point the dot at the mark on the
bottom of the wall. Then, using the up/down arrows on the
remote control, rotate the dot upwards. If the center of the
dot scans over the mark on the top of the wall, the laser is
properly calibrated.
nOTE: This check should be done with a wall no shorter than
the tallest wall for which this laser will be used.
