Horizontal Beam - Pitch Direction

Checking the horizontal pitch calibration of the laser requires

a single wall at least 30

′

(9m) long. It is important to conduct

a calibration check using a distance no shorter than the distance

of the applications for which the tool will be used.

1.

Place the laser against the end of the wall

(Figure

E

1

).

2.

Move the

Power/Transport Lock switch to the right

(Figure

A

3

) to turn

the laser ON in self-leveling mode and display

a horizontal laser beam.

3.

At least 30

′

(9m) apart along the laser beam, mark

a

and

b

.

4.

Move the laser to the opposite end of the wall

(Figure

E

2

).

5.

Position the laser toward the first end of the same wall and

parallel to the adjacent wall.

6.

Adjust the height of the laser so the center of the beam is

aligned with

b

.

7.

Directly above or below

a

, mark

c

along the laser beam

(Figure

E

).

8.

Measure the distance between

a

and

c

.

9.

If your measurement is greater than the

Allowable

Distance Between

a

and

c

for the corresponding

Distance Between

a

and

b

in the following table, the

laser must be serviced at an authorized service center.

Vertical Beam - Plumb

Checking the vertical (plumb) calibration of the laser can be

most accurately done when there is a substantial amount of

vertical height available, ideally 30

′

(9m), with one person on

the floor positioning the laser and another person near a ceiling

to mark the position of the beam. It is important to conduct

a calibration check using a distance no shorter than the distance

of the applications for which the tool will be used.

1.

Place the laser at least 3.28 ft (1.0m) from a door jamb

(Figure

F

1

).

2.

Move the

Power/Transport Lock switch to the right

(Figure

A

3

) to turn

the laser ON in self-leveling mode and display

a horizontal laser beam.

3.

Press

once to display the vertical beam

.

4.

Aim the vertical laser beam toward the door jamb

.

5.

Along the bottom of the laser beam, mark three locations

a

,

b

, and

c

; where

b

is midway between

a

and

c

.

6.

Where the top of the laser beam appears at the top of the

door jamb, mark

e

.

7.

Move the laser to the opposite side of the door jamb

(Figure

F

).

8.

Align the bottom of the laser beam with

a

,

b

, and

c

.

9.

Where the top of the laser beam appears at the top of the

door jamb, mark

f

.

10.

Measure the distance between

e

and

f

.

11.

If your measurement is greater than the

Allowable

Distance Between

e

and

D

in the following table, the laser must be

Using the Laser

Operating Tips

•

Always mark the center of the beam (dot) created by the

laser.

•

Extreme temperature changes may cause movement of

internal parts that can affect accuracy. Check your accuracy

often while working.

•

If the laser is ever dropped, check to make sure it is still

calibrated.

•

As long as the laser is properly calibrated, the laser is self-

leveling. Each laser is calibrated at the factory to find level

as

long as it is positioned on a flat surface within average ± 4°

of level. No manual adjustments are required.

•

Use the laser on a smooth, flat, level, surface.
