ACCURACY FIELD CHECK
NOTICE
Horizontal Height Accuracy
It is also suggested to mount the Laser Level to a
Tripod for easy adjustment.
1.
3. Direct the front laser beams against the nearest
wall A and allow to self-level. Mark the centre of
where the horizontal and vertical lines cross on
the wall (point I).
4. Rotate the tool 180° without changing the height,
allow it to self-level, and mark the centre of where
the horizontal and vertical lines cross on the op-
posite wall B (point II).

6. Adjust the height of the tool (using the tripod or by
adding shims, if required) such that the intersection
of the vertical and horizontal lines are projected
exactly against the previously marked point II on
wall B. Allow the tool to self-level.
7. Rotate the tool 180° without changing the height,
allow it to self-level, and mark the intersection of
the laser lines on wall A (point III). Point III should
be aligned as vertically above or below point I on
wall A as possible.

Perform the Accuracy Field Check
procedure immediately upon
unboxing of each new Laser Level and before
exposure to jobsite conditions. See "Accuracy
Field Check" for information.
Should any
deviation from listed product accuracy be found,
please contact a
MILWAUKEE
®
service facility.
Failure to do so could result in rejection of warranty
claim.
Ambient temperature gradients can impact laser
accuracy. For accurate and repeatable results, the
following procedure should be conducted with the
laser elevated off the ground and placed in the
centre of the working area.
Abusive treatment of the Laser Level, such as
excessive impacts from repeated or high drops, can
also lead to deviations in product accuracy.
Therefore, it is recommended to conduct the
Accuracy Field Check procedure after any impact or
before completing any critical jobs.
A free measuring distance of approximately 20m on
a firm surface between two walls or structures A and
B is required for this check.
Move the tool within 30cm of wall B. Turn the tool
to ON. Turn on Horizontal Plane and Side
Vertical Plane. Align intersection of the
horizontal and vertical lines in the general
direction of point II on wall B.
Securely mount the tool within 30cm of wall A.

2. Turn the tool to
ON. Turn on Horizontal Plane
and Side Vertical Plane.
The distance between points I and III on wall A is
the height deviation (d) of the tool. This distance
should not exceed 3.18mm (max.) at 10m
(12.72mm at 40m). For the measuring distance of
2 x 20m = 40m, the maximum allowable
deviation (d) is: 40m x ± 3.18mm ÷ 10m =
±12.72mm.
