To PAIR the remote/receiver with the laser, select the pairing icon in the main menu of the remote/ receiver, then press and hold the pairing button on the laser. The Pair Indicator LED will flash white while the tool searches for the remote/receiver. When the device connection is successful, an audible tone will sound, and the Pair Indicator LED will remain solid white.

NOTE:
Only 1 laser and 1 remote/receiver can be paired at a time to the laser. If the connection fails after 30 seconds, the Pair Indicator LED will stop flashing, and the tool will beep multiple times to indicate a failure. The operation will need to be repeated.

Operating Modes

Rotational Mode
For best performance when using the remote/receiver, use 600 RPM. Different RPMs can be selected by pressing the Rotational Speed Button on the laser (1200, 300, and 600).
Sweep Mode
When using sweep mode, the laser beam oscillates within a limited range. The visibility of the laser beam is enhanced compared to rotational mode. Different sweep angles can be selected by pressing the Sweep button on the laser (0°,10°, 45°, and 90°).
Plumb Point Mode
The laser will default to Plumb Point Mode when placed in the vertical orientation. Use the plumb dot projected on the working surface to orient and set up the lasers before entering the Rotational or Sweep Mode.

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 either by the one-minute timer or 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 surface. This error occurs when the working surface causes the laser to be outside the leveling range. After, try pressing the Leveling Mode Button or power cycling the laser to trigger a relevel. If the problem persists, please contact an authorized MILWAUKEE service facility for support.

Complete Manual Mode
The laser will default to Auto-Leveling Mode. Complete Manual Mode can be used to deactivate Auto-Leveling and allow the user to manually position the laser plane. Ensure the laser has self-leveled (Leveling Mode Indicator LED is solid green).

Press the Leveling Mode button.
The Leveling Mode Indicator LED will turn solid red and remain on (the laser will no longer attempt to Auto-Level).
To turn OFF, press the Leveling Mode button again. The Leveling Mode Indicator LED will flash green and become solid once the level is achieved. Entering/exiting Complete Manual Mode will reinitialize the Bump Alarm to allow for further setup.

Manual Slope Mode
The laser plane can be manually sloped using a paired remote/receiver. When in Manual Slope Mode, the Leveling Mode Indicator LED will illuminate yellow. The laser will auto-level in one axis while sloping in the other.

Start the operation using the remote/receiver. See the remote/receiver manual.
To Exit Manual Mode from the laser, press the Leveling Mode button. The laser will enter Auto-Leveling Mode and begin to self-level. The Leveling Mode Indicator LED will turn solid green when leveling is achieved.

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.

The Bump Alarm will only be off while the laser establishes a new position.
Once the Leveling Mode is established, the Leveling Mode Indicator LED becomes solid (green, yellow, or red), and the Bump Alarm Indicator LED will begin to flash white. During this time, disturbances will not trigger an alarm but will restart the initialization timer. After 30 seconds with no adjustments or inputs, the Bump Alarm Indicator LED will become solid white and the Bump Alarm will be 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 LED will flash white, and the Leveling Mode Indicator LED will flash red. The laser will play an audible alarm.

NOTE:
The laser will default to High Sensitivity. Set up the laser on a flat and stable surface to avoid interruptions in operation. If the Bump Alarm becomes overly sensitive for environmental conditions, the setting can be viewed and changed using a paired remote/receiver.

Clearing the Bump Alarm (Option 1):
Press the Leveling Mode button, and the laser will run the Auto-Leveling sequence. Additional setup may be needed if the laser was moved from its previous position.

Clearing the Bump Alarm (Option 2):
If the user suspects the laser has not been significantly disturbed, press the Rotational Speed button to clear the warning or clear with the OK button on the paired remote/receiver and the laser head will start spinning in its current position. Inspect the laser plane to determine if it has been moved to determine if re-set up is needed.

NOTE: The laser will recall previous settings that were applied.

Sleep Mode
To conserve battery, the laser can be put into Sleep Mode from a paired remote/receiver. In this mode, the laser head will stop spinning, and the laser diode and the Leveling Mode Indicator LED will turn off. The Pairing Indicator LED and Bump Alarm Indicator LED will continue to display the current setting.

To turn ON Sleep Mode, select the Sleep icon from the main menu on the remote/receiver.
Press the OK button to send the laser to “sleep” mode.
To turn OFF Sleep Mode, press any button on the laser or follow instructions to “wake” on a paired remote/receiver. The laser will function with the same settings and modes as when it entered Sleep Mode.

Temperature Alarm
The laser monitors temperatures when the tool is active or in Sleep Mode. If the minimum or maximum operating temperature limits are exceeded, the Leveling Mode Indicator LED will flash, alternating between red>green>red; in this pattern, laser diode will turn off, and the head will stop rotating. The laser will automatically turn off after 5 minutes of this alarm.

Clearing the Temperature Alarm:

Wait for the temperature to return to the normal operating range stated in the “Specifications” section.
When the tool reaches normal operating temperature, the tool will start the self-leveling process.

NOTE:
The internal temperature of the tool may be several degrees warmer than the ambient temperature. Allow 2 hours for the tool to reacclimate to the new temperature before restarting.

Troubleshooting

Startup Failure – If the Leveling Mode Indicator LED flashes in an amber color immediately after the laser is turned on, this is a result of a system error. Return the tool to an authorized MILWAUKEE service center.
Leveling Error – The Leveling Indicator LED will flash red, and the alarm will sound. Ensure that the laser is on a level surface and the job site is clear of obstacles, any pressing of the buttons on the rotary laser may trigger the bump alarm or releveling may occur. If setting up in vertical orientation, check if it’s in the correct orientation. The laser will only work in one orientation, with the keypad facing up and paral-lel to the ground. Try pressing the Leveling Mode Button to initiate Auto-Leveling. Try power cycling the laser 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 a paired remote/receiver. Clear the Bump Alarm by using one of the options from “Clearing the Bump Alarm” section. If this fails, return the laser to an authorized MILWAUKEE service center.
Temperature Alarm – If the red/green Leveling Mode Indicator LED is flashing, ensure the laser is within the operating temperature range. Note that the internal temperature of the tool may be 5 – 10o warmer than the ambient temperature. If stored in excessive heat or cold, allow at least 2 hours to acclimate to ambient temperature before turning on the tool.
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 indica-tor that the laser is locked out. Use the ONE-KEY™ app to connect and unlock the tool.

Pairing Failure:

Ensure the remote/receiver is powered on, within the distance range and in Pairing Mode.
Avoid artificial overhead lighting on the remote/receiver sensor.
Avoid the laser projecting a beam onto the remote/receiver sensor during pairing.
Avoid transmitting devices
Place the laser on a stable surface during pairing to prevent interruption from bump alarms. For best results, pair in the horizontal orientation.

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 Check procedure immediately upon unboxing of each new laser and before exposure to job site 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 the rejection of the warranty claim.

Influences on Accuracy
Ambient temperature changes can impact laser ac-curacies. For accurate and repeatable results, the following procedure should be done with the laser 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 changes in product accuracy. Therefore, it is recommended to perform the “Field Check” procedure after any drops 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 a wall. Ensure the area is clear of objects before doing this operation. This procedure must be performed twice to check the plane accuracy for both the X and Y axes.

Mount the laser on a tripod.
Turn ON the laser by pressing the power button, and wait for the self-leveling sequence to finish. The Leveling LED Indicator will be solid green.
Mark the center of the beam on the wall point I. If the laser is not visible, use a compatible remote/receiver to find the plane and mark the center point.
Rotate the laser 180o, and wait for the self-leveling to finish. Mark the center of the beam on the wall (point II). Ensure point II is as vertical as possible above or below point I.
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 1/8″ at 200′ (or 1/16″ at 100′).
Repeat the steps above in other axis.

Leveling Accuracy for Vertical Orientation
Ensure the area is clear of obstructions before do-ing this operation. Attach a Plumb Bob to the ceiling near a wall. The Plumb Bob should be a minimum of 30′ in length.

Ensure the work area is on a flat, clean surface.
Place the laser in the correct vertical orientation with the keypad facing up and parallel to the ground. If possible, elevate off the ground. Be sure the setup is stable before proceeding to the next step.
Turn ON the laser by pressing the power button, and wait for the self-leveling sequence to finish. The Leveling LED Indicator will be solid green.
Press the Rotational Speed button to start the laser head rotation. Manually turn the tool to align the laser, so it crosses the Plumb Bob line at least 30′ above the ground.
Measure the distance between the Plumb Bob string and the laser at the base of the wall. This distance represents the laser’s actual deviation from plumb. The maximum deviation allowed should be 3/64″ over 30′ (or 1/8″ at 100′).

Plumb Dot Accuracy
A free measuring distance of approximately 15′ between the floor and ceiling on a firm surface is required. It’s suggested to elevate the tool off the ground for this operation.

Place the tool within 1′ of the floor.
Turn ON the tool by pressing the power button.
Mark the center of the plumb point on the ceiling (point I).
Rotate the tool 180° being as careful as possible to keep the center of the laser in the exact same location.
Mark the center of the top plumb point on the ceiling (point II).
The distance between (points I and II) on the ceiling is the deviation (d) of the tool. This distance should not exceed 3/64″ (max.) at 30′. For the measuring distance of 2 x 15′ = 30′, the maximum allowable deviation (d) is: 30′ x ±3/64″ ÷ 30′ = ±3/64″.

NOTE:
If any of the above accuracies are out of spec, return the laser to the nearest authorized MILWAUKEE service center for recalibration.
