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.4. The tool is ready once the emitted lines 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 points will flash rapidly (3 flashes per second). Relocate or adjust the work surface.

Troubleshooting

If the tool does not turn on:

Ensure battery is installed properly. Fuel gauge should indicate remaining charge when correctly installed.
Ensure 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 an appropriate ambient temperature between -10°C to 40°C before turning on the tool.

If 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 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.

Horizontal Height Accuracy

A free measuring distance of approximately 20m on a firm surface between two walls or structures (indicated as ‘A’ and ‘B’ below) is required for this check. It is also suggested to mount the Laser Level to a an appropriate tripod for easy adjustment.

.Securely mount the tool within 30cm of wall ‘A’ as shown below.
Turn the tool to ON and to Perpendicular Level & Plumb Lines Mode.
Direct the front laser beam against the nearest wall A and allow to self-level. Mark the centre of the laser cross on the wall (point I).
Rotate the tool 180° without changing the height, allow it to self-level, and mark the centre of the laser cross on the opposite wall B (point II)
Move the tool within 30cm of wall B. Allow the laser to self level. Align the laser cross in the general direction of point II on wall B.
Adjust the height of the tool (using the tripod or by adding shims, if required) to align the laser cross directly onto point II on wall B. Allow the tool to self-level.
Rotate the tool 180° without changing the height, allow it to self-level, and mark the centre of the laser cross 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 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

Horizontal Leveling Accuracy

A free measuring space of approximately 10m (33′) x 10m (33′) on a firm surface between two walls or structures A and B is required for the check. It is also suggested to mount the Laser Level to a commercially available Tripod for easy adjustment. Securely mount the tool on one side of the room and centered between walls A and B. Direct the laser lines toward the other side of the room such that the horizontal line appears on both walls A and B. Allow the laser to Self-Level

Turn the tool to ON and to Horizontal Level Line mode.
At a distance of 5m from the laser, mark the centre of the horizontal line on Wall A (Point I). Do the same on Wall B (Point II).
Move the Laser 10m toward the opposite wall and rotate the laser 180°. Allow the laser to Self-Level.
Adjust the height of the tool (using the tripod or by adding shims, if required) such that the center of the horizontal line is projected exactly against the previously marked point II on wall B. Ensure the Laser is self-leveled after
Mark the center of horizontal line on wall A (point III). Take care that point III is aligned as vertical as possible above or below point
The distance d between marked points I and III on wall A indicates the actual deviation (d) of the
For the Measuring distance of 2 x 10m = 20m, the maximum allowable deviation (d) is: 20m x ±3.18mm ÷ 10m = ±6.36mm Thus, the difference d between points I and III should not exceed 6.5mm (max.) at 20m.

Vertical Leveling Accuracy

A door opening with approximately 2.5m of space on each side of the opening is required for this

1. Securely mount the tool 2.5m from one side of the door opening
2. Turn the tool to ON and to Vertical Plumb Line
3. Position the tool with the laser towards the door Allow the tool to self-level.
4. Mark the centre of the vertical laser line on the floor in the middle of the door opening (point I), at a distance of 2.5m (8′) beyond the door opening (point II), and at the upper edge of the door opening (point III).
5. Move the laser level directly behind point II on the other side of the door. Align the vertical laser line so the center is directly aligned with points I and
6. Mark the center of the vertical line at the upper edge of the door opening (point IV).
7. Measure the height of the door
8. 1. The maximum vertical deviation (d) is: d max = 2X H (door opening) x ±3.18mm ÷ 10m Example: for a door opening height of 2.05m, the maximum permitted deviation (d) is: d max = 2 x 2.05m x ±3.18mm ÷ 10m = ± 1.3mm Therefore, the measurement between points III and IV on the upper door opening should not exceed 1.3mm in a 2.05m doorway.

Plumb Dot Accuracy (L4 CPL)

A free measuring distance of approximately 10m (33′) between floor and ceiling on a firm surface is required for this check. It is suggested to install riser block, if not already equipped.

Place the tool within 30cm of the Turn the tool to ON and to Perpendicular Level & Plumb Lines Mode.
