OPERATION
WARNING Tporary effects o reduce the risk of injury or temon vision, do not-look directly into the laser when it is on.
CAUTION performance of procedures otherUse of controls or adjustments or than those specified herein may result in hazard-ous radiation exposure.
NOTICE Perform the Accuracy Field Checkprocedure immediately upon unboxing of each new laser and before exposure to jobsite conditions. See “Accuracy Field Check” for information. Should any deviation from listed product accuracy be found, please contact an authorized MILWAUKEE service center. Failure to do so could result in rejection of warranty claim.

Turning the Rotary Laser ON/OFF

• To turn the laser ON, press the power button. When powered on, the laser will begin the leveling sequence.
  Once level and ready to use, the Leveling
  Mode Indicator LED will become solid green.

• To turn the laser OFF, press the power button. The laser diode will turn off, the head will stop rotating, and all LEDs will turn off.

Rotational Mode
When the laser initially turns on, the laser will automatically start to self- level. The laser head will rotate at 600 RPM, and the laser beam will become visible.

Auto-Leveling Mode
When the laser initially turns on, the laser will automatically start to self- level. The Leveling Mode Indicator LED will begin flashing green.

• During the leveling process, the Bump Alarm will not be active. When the laser is leveled, the Leveling Mode Indicator LED will be solid green, and the laser head will start to rotate. The laser will be ready for use.
• If the leveling process fails by the one-minute timer or is out of the leveling range, the Leveling Mode Indicator LED flashes red, the laser diode turns off and stops rotating, and an audible tone will sound. NOTE: If the laser fails to level, ensure the laser is on a stable and flat surface. This error occurs when the working surface causes the laser to be outside the leveling range. After, try pressing the Leveling button or power cycling the laser to trigger a relevel. If the problem persists, please contact an authorized MILWAUKEE service center for support.

Bump Alarm
Due to the laser’s high leveling accuracy, the laser is very sensitive to knocks, vibrations, and changes in position. The Bump Alarm will be triggered if the laser is moved from its initial location. Once auto-leveling is finished and the Leveling Mode Indicator LED be-comes solid green, the Bump Alarm Indicator LEDs will begin to flash white indicating the Bump Alarm is initializing. During this time, disturbances will not trigger an alarm but will restart the initialization timer. If the laser has not moved for 30 seconds, the Bump Alarm Indicator LEDs will become solid white. This indicates that the Bump Alarm is active. Any bumps above the sensitivity limits will trigger the alarm. The laser diode will turn off, the head will stop rotating, the Bump Alarm Indicator LEDs will alternate flashing white, the Leveling Mode Indicator LED will flash red, and an audible tone will sound.

Clearing the Bump Alarm

In the event of a Bump Alarm, press either the Level-ing button or the Bump Alarm button. The alarm will clear, and the laser will begin leveling sequence and re-initiate the Bump Alarm. The laser can be power cycled to clear the Bump Alarm if needed. NOTE: Check the position of the laser plane to determine if it has moved. Additional setup may be needed to re-align the laser with previous benchmarks.

Changing the Bump Alarm Sensitivity
The Bump Alarm sensitivity default is set to high from the factory, both Bump Alarm Indicator LEDs will be illuminated. Set up the laser on a flat and stable surface to avoid interruptions in operation. If the Bump Alarm becomes overly sensitive to the environmental conditions, the setting can be changed by pressing the Bump Alarm button. Only the left Bump Alarm Indicator LED will illuminate, indicating the lower sensitivity selected. The Bump Alarm will re- initiate when the sensitivity is changed. Once complete, the LED will turn solid white to show that the Bump Alarm is armed. To switch back, press the Bump Alarm button again.

Complete Manual Mode
Ensure the laser completes self-leveling successfully before entering this mode. Complete Manual Mode is only available to engage when the laser is level, and the leveling LED is solid green.

1. To turn ON Complete Manual Mode, press the Leveling button.

2. The Leveling Mode Indicator LED will turn solid red, and the laser will no longer attempt to self-level.
   NOTE: The Bump Alarm Indicator LEDs will turn off. The Bump Alarm is not available in Complete Manual Mode.

3. To turn OFF Complete Manual Mode, press the Leveling button again, and the laser will begin a self-leveling sequence and the Levling Mode Indicator LED will go back to solid green if leveled properly.

Manual Masking
To avoid interference with other users on the jobsite, manual masking flaps can be used to block 4 indi-vidual quadrants of the rotating laser plane.

• To MASK, use finger to flip up the mask in the de-sired quadrant to block the laser beam exiting the window.
• To UNMASK, simply use finger to flip the mask back down.

Troubleshooting

• Ensure the battery is installed correctly. The fuel gauge should indicate the remaining charge when correctly installed.
• Ensure the battery is charged.
• Leveling Error – The Leveling Mode Indicator LED will flash red, and the alarm will sound. Ensure that the laser is on a level surface and that the tool is in the proper Horizontal orientation. Try pressing the Leveling button to initiate auto-leveling. Try power cycling the tool to clear the setting. If this fails, return the laser to an authorized MILWAUKEE service center.
• Bump Alarm too Sensitive – Ensure the laser is on a level and stable surface. Try changing to a less sensitive setting using the Bump Alarm button on the laser keypad. Clear the Bump Alarm by using one of the options from the “Clearing the Bump Alarm” section. If this fails, return the laser to an authorized MILWAUKEE service center.
• ONE-KEY™ Lock Out – The laser will turn on briefly but shut down after ~15 seconds. The ONE-KEY™ Indicator LED will be flashing red. This is an indicator that the laser is locked out. Use the ONE-KEY™ app to connect and unlock the tool.
  NOTE: If all the recommended troubleshooting fails, power cycle the laser with the Power button. Try removing/re-inserting the battery to restart the tool. If the problem persists, return the laser to an authorized MILWAUKEE service center.

ACCURACY FIELD CHECK

NOTICE Perform the Accuracy Field procedure immediately upon unboxing of each new laser and before exposure to jobsite conditions. See “Accuracy Field Check” for information. Should any deviation from listed product accuracy be found, please contact an authorized MILWAUKEE service center. Failure to do so could result in rejection of warranty claim.

Influences on Accuracy
Ambient temperature can impact laser accuracies. 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, such as excessive impacts from drops, can also lead to deviations in product accuracy. Therefore, it’s recommended to conduct the field check procedure after any impacts or before completing any critical jobs. NOTE: Accuracies and leveling times are measured at ambient temperatures (68°F). Use of the tool at extreme temperatures (even within the operating temperature range) may negatively impact these specifications.

Leveling Accuracy for Horizontal Orientation
A tripod for this operation is suggested. Use a distance of 100′ between the center of the laser and the wall. Ensure the area is clear of objects and the laser is level as possible before doing this operation. This procedure must be performed twice to check the plane accuracy for both X and Y axes.

1. Mount the laser on a tripod.

2. Turn the laser ON by pressing the power button, and wait for the self-leveling sequence to finish. The Leveling Mode Indicator LED will be solid green when achieved.

3. Mark the center of the beam on the wall (point I). If the laser is not visible, use a compatible receiver to find the plane and mark the center point.
   

4. Rotate the laser 180o without changing height, and wait for the self-leveling sequence. Mark the center of the beam on the wall (point II). Ensure (point II) is as vertical as possible above or below (point I).

5. Measure the vertical distance, (d) between points (I) and (II). This is the actual height deviation of the laser in the axis checked over 200′. The maximum deviation allowed should be 3/16″ at 200′ (or 3/32″ at 100′).
   

6. Repeat the steps above for the other axis. NOTE: If any of the above accuracies are out of spec, return to an authorized MILWAUKEE service center for recalibration.
