**WARNING Recharge only with the charger specified for the battery. For specific charging instructions, read the operator’s manual supplied with your charger and battery. Removing/Inserting the Battery To remove the battery, push in the release buttons and pull the battery pack away from the tool.
WARNING Always remove battery pack before changing or removing accessories. To insert the battery, slide the pack into the body of the tool. Make sure it latches securely into place.
WARNING** Only use accessories specifically recommended for this tool. Others may be hazardous.

Power Save
Use power save mode to extend the battery run time. Power save mode is indicated by dimmed laser beams and the Mode indicator pulsing. Visual range is decreased in power save mode. To turn power save mode ON or OFF, press and hold Mode button for 3 seconds. The tool will automatically switch to power save mode if less than 7% of battery charge remains.
Fuel Gauge
To determine the amount of charge left in the battery, turn the tool ON. The Fuel Gauge will light up for 2-3 seconds. When less than 10% of charge is left, 1 light on the fuel gauge will flash 4 times. To signal the end of charge, 1 light on the fuel gauge will flash 8 times and the tool will not run. Charge the battery pack. If the battery becomes too hot, the fuel gauge lights will flash and the tool will not run. Allow the battery to cool down.
When automatically switched to power save mode due to low battery, the tool cannot be switched back to normal mode until the battery is charged/replaced.

WARNING To reduce the risk of injury or damage, securely mount/attach the laser before starting an operation. Injury/damage may occur if the laser falls.

Mounting/Adjusting the Laser Level
The pivot bracket can be used to mount the laser level in multiple ways:

• Use the embedded magnets to secure the laser level to steel studs, steel beams, etc.
• Use the keyhole slot to hang the laser level on the wall with a nail or screw.
• Set the laser level on a flat surface.
• Position the laser and/or wall mount on a stable surface.
• Use the 1/4″-20 or 5/8″-11 threaded insert to mount on a tripod.
• Once the level is mounted, use the micro adjustment knobs to fine tune the laser line.

OPERATION

WARNING To reduce the risk of injury or tem- porary 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 Check procedure immediately upon unboxing of each new Laser Level and before exposure to jobsite 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. Laser Mode Indicator LED will display, and horizontal level line will imme- diately be emitted from aperture in the laser housing.

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

Use the MODE button to cycle through the three laser modes:
 Horizontal Level Line
 Vertical Plumb Line & Plumb Points
 Perpendicular Level & Plumb Points
The green laser mode indicators will display the selected mode.

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 lines are con- tinuous 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 beams 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 acclimate to ambient temperature 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 con- tact a MILWAUKEE service facility. 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 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.

1. Securely mount the tool within 1′ of wall A
   

2. Turn the tool to ON and to Perpendicular Level & Plumb Points Mode.

3. Direct the front laser beam against the nearest wall A and allow to self-level. Mark the center of the laser cross on the wall (point I).

4. Rotate the tool 180° without changing the height, allow it to self-level, and mark the center of the laser cross on the opposite wall B (point II).
   

5. Move the tool within 1′ of wall B. Allow the laser to self level. Align the laser cross in the general direction 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 laser cross directly onto point II on wall B. Allow the tool to self-level.

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

8. The distance between points I and III on wall A is the height deviation (d) of the tool. This distance should not exceed 1/8″ (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″.

Horizontal Leveling Accuracy
A free measuring space of approximately 33’x33′ 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 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.

1. Turn the tool to ON and to Horizontal Level Line mode.

2. At a distance of 16.5′ from the laser, mark the center of the horizontal line on Wall A (Point I). Do the same on Wall B (Point II).
   

3. Move the Laser 33′ toward the opposite wall and rotate the laser 180°. Allow the laser to Self-Level.

4. djust 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 alignment.

5. 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 I.

6. The distance d between marked points I and III on wall A indicates the actual deviation (d) of the tool.

7. For the Measuring distance of 2 x 33′ = 66′, the maximum allowable deviation (d) is: 66′ x ±1/8″ ÷ 33′ = ±1/4″. Thus, the difference d between points I and III should not exceed 1/4″ (max.) at 66′.

Vertical Leveling Accuracy
A door opening with approximately 8′ of space on each side of the opening is required for this check.

1. Securely mount the tool 8′ from one side of the door opening.

2. Turn the tool to ON and to Vertical Plumb Line & Plumb Points Mode or Perpendicular Level & Plumb Point Mode.

3. Position the tool with the laser towards the door opening. Allow the tool to self-level.

4. Mark the center of the vertical laser line on the floor in the middle of the door opening (point I), at a dis- tance of 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 II.

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 opening.

8. The distance between points III and IV on the upper door opening is the vertical deviation (d) of the tool.

9. The maximum vertical deviation (d) is: dmax = 2X H (door opening) x ±1/8″ ÷ 33′. Example: for a door opening height of 7′, the maximum permitted deviation (d) is: dmax = 2 x 7′ x ±1/8″ ÷ 33′ = ±0.05″. Therefore, the measurement between points III and IV on the upper door opening should not exceed 0.05″ in a 7′ doorway.

Plumb Dot Accuracy
A free measuring distance of approximately 16.5′ between floor and ceiling on a firm surface is required for this check. It is suggested to install riser block, if not already equipped.

1. Place the tool within 1′ of the floor.

2. Turn the tool to ON and to Vertical Plumb Line Mode or Perpendicular Level & Plumb Point Mode.

3. Set tool on ground and mark the center of the plumb point on the ceiling (point I). Also, mark the center of the plumb point on the floor (point II).
   

4. Rotate the tool 180°. Align the center point of the laser beam directly onto the floor point II.

5. Mark the center of the top plumb point on the reference line on the ceiling (point III).
   

6. The distance between points I and III on the ceiling is the deviation (d) of the tool. This distance should not exceed 1/8″ (max.) at 33′. For the Measuring distance of 2 x 16.5′ = 33′, the maximum allowable deviation (d) is: 33′ x ±1/8″ ÷ 33′ = ±1/8″.
