1. Place the laser tool on a tripod and close to wall #1 as shown in Fig 1. Turn on both a
horizontal and vertical line. Mark the intersection of the points P
1
.
2. Rotate laser tool 180° and mark point P
2
at intersection of the lines on wall #2
3. Move laser tool close to wall #2 and align point P
3
at previously marked point P
2
4. Rotate laser tool 180° and mark point P
4
on wall #1
5. Measure the vertical distance between P
1
and P
4
to get D
3
.
If the measurement is greater than the values shown below, the laser must be serviced at an
authorized service center
Distance Between Walls Measurement Between Marks
(D
3
)
10' (3 m) 1/8" (3 mm)
20' (6 m) 7/32" (5.5 mm)
30' (10 m) 5/16" (8 mm)
Horizontal Beam Accuracy
(See Figure 2)
1. Place laser tool as shown with laser ON. Aim vertical beam towards the first corner or a
set reference point. Measure out half of the distance D
1
and mark point P
1
.
2. Rotate laser tool and align front vertical laser beam with point P
1
. Mark point P
2
where the
horizontal and vertical laser beams cross.
3. Rotate laser tool and aim vertical beam towards the second corner or set reference point.
Mark point P
3
so that it is vertically in line with points P
1
and P
2
.
4. Measure the vertical distance D
2
between the highest and lowest point.
If the measurement is greater than the values shown below, the laser must be serviced at an
authorized service center.
Distance Between Walls Measurement Between Marks
(D
3
)
10' (3 m) 1/8" (3 mm)
20' (6 m) 7/32" (5.5 mm)
30' (10 m) 5/16" (8 mm)
Vertical Beam Accuracy
(See Figure 3)
1. Measure the height of a reference point to get distance D
1
. Place laser tool as shown
with laser ON. Aim vertical beam towards reference point. Mark points P
1
, P
2
, and P
3
as
shown.
2. Move laser tool to opposite side of reference point and align the same vertical beam with
P
2
and P
3
.
3. Measure the horizontal distances between P
1
and the vertical beam from the 2nd location.
If the measurement is greater than the values shown below, the laser must be serviced at an
authorized service center.
