allow it to self-level, and mark the center point of
the laser point on the opposite wall B (point II).

5. Move the tool within 1' of wall B. Turn on the tool
and align the front laser point in the general direc-
tion of point II on wall B.
6. Adjust the height of the tool (using the tripod or by
adding shims, if required) to align the center point
of the laser beam directly onto point II on wall B.

Rotate the tool 180° without changing the height,
allow it to self-level, and mark the center point of

be aligned as vertically above or below point I on
wall A as possible.

8. The distance between points I and III on wall A is
the height deviation (d) of the tool. This distance
should not exceed 1/4" (max.) at 33' (1" at 132').
For the Measuring distance of 2 x 66' = 132', the
maximum allowable deviation (d) is: 132' x ±1/4"
÷ 33' = ±1"
Vertical Leveling Accuracy
A free measuring distance of approximately 16.5'
between floor and ceiling on a firm surface is required
for this check.
1. Draw a straight line on the ceiling to use as a
reference line.
2.
Securely mount the tool within 1' of the floor.
3. Turn on the tool.
4.
Position the tool so that the bottom plumb point
can be seen on the floor and the center of the top
plumb point is located on the reference line on the
ceiling. Allow the tool to self-level.
5. Mark the center of the top plumb point with the
reference line on the ceiling (point I). Also, mark
the center of the bottom plumb point on the floor
(point II).

6.
Rotate the tool 180°. Align the center point of the
laser beam directly onto the floor point II.
7. Position the tool to align the center of the top plumb
point onto the reference line on the ceiling. It may
be necessary to rotate the tool slightly to align.
Allow the tool to self-level.
8. Mark the center of the top plumb point on the
reference line on the ceiling (point III).

9. The distance between points I and III on the ceiling
is the deviation (d) of the tool. This distance should
not exceed 1/4" (max.) at 33'.
For the Measuring distance of 2 x 16.5' = 33', the
maximum allowable deviation (d) is: 33' x ±1/4"
÷ 33' = ±1/4".
Troubleshooting
If the tool does not turn on:
• Ensure batteries are inserted correctly according to
the +/- polarity marked in the compartment.
• Replace batteries that may be at the end of life.
• Ensure the tool's internal temperature is within
specified operating ranges. If stored in excessive
heat or cold, allow at least 2 hours to acclimate to
ambient temperature before turning on the tool.
If problem persists, please contact Empire Level
Customer Service for support.
ACCURACY FIELD CHECK
NOTICE
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 Empire
Level Customer Service. Failure to do so could result
in rejection of warranty claim.
Influences on Accuracy
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 center
of the working area.
Abusive treatment of the Laser Level, such as exces-
sive impacts from drop, can also lead to deviations
in product accuracy.
Therefore, it is recommended to conduct the Field
Check procedure after any impact or before complet-
ing any critical jobs.
Horizontal Leveling Accuracy
A free measuring distance of approximately 66' on a
firm surface between two walls or structures A and
B is required for this check.
It is also suggested to mount the Laser Level to a
commercially available Tripod for easy adjustment.
1. Securely mount the tool within 1' of wall A.
2. Turn on the tool.
3. Direct the front laser beam against the nearest
wall A and allow to self-level. Mark the center of
the laser point on the wall (point I).

MAINTENANCE
WARNING
To reduce the risk of injury, always
remove the battery before perform
-
ing any maintenance. Never disassemble the tool.
Maintain Laser Level
Maintain tools. If damaged, have the tool repaired
before use. Accidents may be caused by poorly
maintained tools.
WARNING
To reduce the risk of personal in-
jury and damage, never immerse
your tool in liquid or allow a liquid to flow inside
them.
Cleaning
Keep tool handles clean, dry and free of oil or grease.
Use only mild soap and a damp cloth to clean the
tool since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing am-
monia. Never use flammable or combustible solvents
around tools.
Cleaning the Lenses
Blow off loose particles with clean compressed air.
Carefully wipe the surface with a cotton swab moist-
ened with water.
Repairs
This tool has limited serviceable parts. Do not open
housing or disassemble tool. Contact Empire Level
Customer Service for support.
ACCESSORIES
WARNING
Use tools only with specifically
designated accessories.
Use of any
other accessories may create risk of injury.
