WARNING! Do not exceed the maximum capacity marked on the lanyard label. Exceeding maximum capacity may result in serious injury or death.

OPERATION

WARNING
To reduce the risk of injury or temporary effects on vision, do not look directly into the laser when it is on.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
NOTICE
Perform the Accuracy Field Checkprocedure immediately upon unboxing of each new Laser Level and before exposure to job site conditions. See “Accuracy Field Check”
for information.
Turning On/Off
To turn on the laser and unlock the pendulum, rotate the On/Off dial to the desired position. The remaining battery life will be displayed.
WARNING! Do not look directly into laser apertures. Horizontal leveling will immediately be emitted from an aperture in the laser housing.

ON Turns ON the laser and unlocks the pendulum to enable self-leveling.
ON Turns ON the laser but does not unlock the pendulum (self-leveling is disabled). The laser line will flash once every 8 seconds to indicate that the projected line are not level.
NOTE: The ON mode disables self-leveling and therefore is not intended for projecting a level line.
OFF Turns OFF the laser and locks the pendulum. When not in use, turn off the tool and store the Laser Level in the protective carrying case.

Using the Laser Level
1. For best results, place the tool on a work surface that is:
• sturdy
• level (within 4 degrees of true level)
• free of vibrations
• 90° to the work area
2. Turn on the tool.
3. The tool will self-level when placed on surfaces within 4 degrees of true level when dial is unlocked and on.
4. The tool is ready once the emitted line are continuous and no longer moving on the work surface.
5. If the tool cannot achieve a level state (i.e., the work surface is > 4 degrees off true level), the laser line will flash rapidly (3 flashes per second).
Relocate or adjust the work surface.

Troubleshooting

If the tool does not turn on:

Ensure the battery is installed properly. The fuel gauge should indicate the remaining charge when correctly installed.

Ensure the battery is charged.
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 the problem persists, please contact a MILWAUKEE service facility for support.

ACCURACY FIELD CHECK

NOTICE
Perform the Accuracy Field Check procedure immediately upon unboxing of each new Laser Level and before exposure to job site 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 the rejection of the 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 excessive impacts from the drop, can also lead to deviations in product accuracy.
Therefore, it is recommended to conduct the Field Check procedure after any impact or before completing any critical jobs.

Horizontal Height 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 Tripod for easy adjustment.

Securely mount the tool within 1′ of wall A.
Turn the tool to ON.
Direct the front laser beam against the nearest wall A and allow to self-level. Mark the center of the horizontal line on the wall (a point I).
Rotate the full tool with bracket 180° without changing the height, allow it to self-level, and mark the center of the horizontal line on the opposite wall B (point II).
Move the tool within 1′ of wall B. Turn the tool to ON. Adjust the height of the tool (using the tripod or by adding shims, if required) such that the horizontal line is projected exactly against the previous markedpoint II on wall B. Allow the tool to self-level.
Rotate the full tool with bracket 180° without changing the height, allow it to self-level, and mark the center of the horizontal line on wall A (point III). Point III should be aligned as vertically above or below point I on wall A as possible.
The distance between points I and III on wall A is the height deviation (d) of the tool. This distance should not exceed 1/8″ (max.) at 33′ (1/2″ at 132′). For the Measuring distance of 2 x 66′ = 132′, the maximum allowable deviation (d) is: 132′ x ±1/8″ ÷ 33′ = ±1/2″.
