Fuel Gauge
To determine the amount of charge left in the battery, turn the tool ON. When less than 7% of charge is left, 1 light on the fuel gauge will flash continuously.
To signal the end of charge, will flash 4 times and then the tool will shut off. Charge the battery pack.
If the battery becomes too hot, the fuel gauge lights will flash. Allow the battery to cool down.

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 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 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. Horizontal level line and left/right plumb points will immediately be emitted from aperture in the laser housing.

Turns ON the laser and unlocks the pendulum to enable self-leveling.
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 and dots are not level or plumb.
NOTICE: The ON mode disables selfleveling and therefore is not intended for projecting a level or plumb lines/points.
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

Use the MODE button to cycle through the three laser modes:

• Horizontal Level Line & Horizontal Points
• Vertical Plumb Line & Plumb Points
• Perpendicular Level, Plumb Points and Horizontal

Points
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 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 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 contact 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 excessive 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 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.

1. Securely mount the tool within 1′ of wall A.
2. Turn the tool to ON and to Perpendicular Level,Plumb Points, & Horizontal 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 and Horizontal Points mode.
2. Mark the center of the plumb point on the wall (point I). Also, mark the center of the plumb point on the opposite wall (point II).
3. Rotate the tool 180°. Align the center point of the laser beam directly onto the wall point II.
4. Mark the center point of the laser beam on wall A (point III).
5. The distance d between marked points I and III on wall A indicates the actual deviation (d) of the tool.
6. 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 Points, and Horizontal Points 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 distance 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 = 2 x 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.

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 Points, and Horizontal Points 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″.

Squaring Procedure

1. Mark a reference (point x) on the floor that is equidistant from each wall in the center of a room.
   Turn ON the laser and switch to the “Unlocked” position. Ensure that laser is in Perpendicular Level, Plumb Points, and Horizontal Points mode (all lasers ON). Using the down plumb point, align the laser directly over the center of point (x) on the floor. With the laser in place, mark point (I) at the intersection of the lines directly in front of the laser on wall A. Without moving the laser, also mark the center of the right Horizontal point (II) on wall B.

2. Rotate the laser 90 degrees clockwise around plumb point (x) and align the left Horizontal dot with the previously marked point A. With the laser in position, mark point (III) on wall B at the intersection of the perpendicular lines directly in front of the laser. Without moving the laser, mark point (IV) on wall C using the right horizontal point.
   The deviation (d) between points II & III should be no more than 1/8″ at 33′.

3. Lastly, rotate the laser 180º clockwise around plumb point (x) so that the right horizontal point is aligned with the previously marked point I. Without moving the laser, using the
   left horizontal point mark (V) on wall C.The deviation (d) between points IV & V should be no more than 1/8″ at 33′.
