Manual Mode (Figure

)
• Disables self‑leveling function and allows laser unit
to project a rigid laser beam in any orientation.
Accuracy Check and
Calibration
• The laser tools are sealed and calibrated at the
factory to the accuracies specified.
• It is recommended to perform a calibration check
prior to its first use and then periodically during
future use.
• The laser tool should be checked regularly to
ensure its accuracies, especially for precise layouts.
• When performing the accuracy checks, use the
largest area / distance possible, closest to the
operating distance. The greater the area / distance,
the easier to measure the accuracy of the laser.
• The lock must be in the unlocked position to allow
the laser tool to self‑level before checking the
accuracy.

1.
Place laser tool as shown with laser ON. Mark point
P
1
at cross.
2.
Rotate laser tool 180° and mark point P
2
at cross.
3.
Move laser tool close to wall and mark point P
3
at
cross.
4.
Rotate laser tool 180° and mark point P
4
at cross.
5.
Measure the vertical distance between P
1
and P
3
to
get D
3
and the vertical distance between P
2
and P
4
to get D
4
.
6.
Calculate the maximum offset distance and compare
to the difference of D
3
and D
4
as shown in the
equation.
7.
If the sum is not less than or equal to the
calculated maximum offset distance the tool
must be returned to your Stanley Distributor for
calibration.
Maximum Offset Distance:
Maximum = 0.4 mm/m x (D
1
m - (2 x D
2
m))

- D

≤ ± Maximum
Example
•
D
1
= 10 m, D
2
= 0.5 m
• D
3
= - 0.5 mm
• D
4
= 1.0 mm
• 0.4 mm/m x (10 m - (2 x 0.5 m) = 3.6 mm
(maximum offset distance)
• (-0.5 mm) - (1.0 mm) = -1.5 mm
• -1.5 mm ≤ ± 3.6 mm
(TRUE, tool is within calibration)
Horizontal Beam Accuracy (Figure
Ⓙ
)
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.
5.
Calculate the maximum offset distance and compare
to D
2
.
6.
If D
2
is not less than or equal to the calculated
maximum offset distance the tool must
be returned to your Stanley Distributor for
calibration.
