NOTES FOR LI-ION BATTERIES
Use of Li-Ion batteries
Battery packs which have not been used for some time should be
recharged before use.
Temperatures in excess of 50°C (122°F) reduce the performance of
the battery pack. Avoid extended exposure to heat or sunshine (risk
of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, the battery packs have to be fully charged,
after used.
To obtain the longest possible battery life remove the battery pack
from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C and
away from moisture.
Store the battery packs in a 30% - 50% charged condition.
Every six months of storage, charge the pack as normal.
Battery protection for Li-Ion batteries
Under extreme circumstances, the internal temperature of the
battery pack could raise too much. If this happens, the fuel gauge
will fl ash until the battery pack cooled down. After the lights go off ,
the work may continue.
Transport of Lithium batteries
Lithium-ion batteries are subject to the Dangerous Goods Legislation
requirements.
Transportation of those batteries has to be done in accordance with
local, national and international provisions and regulations.
• The user can transport the batteries by road without further
requirements.
• Commercial transport of Lithium-Ion batteries by third parties is
subject to Dangerous Goods regulations. Transport preparation
and transport are exclusively to be carried out by appropriately
trained persons and the process has to be accompanied by
corresponding experts.
When transporting batteries:
• Ensure that battery contact terminals are protected and insulated
to prevent short circuit.
• Ensure that battery pack is secured against movement within
packaging.
• Do not transport batteries that are cracked or leak.

OPERATING MODES
The laser can be used in 3 diff erent operating modes:
1. Auto levelling mode
The device projects the laser beam exactly horizontally or vertically
regardless of its position. The inclination of the unit in this operating
mode may deviate up to 12° from the horizontal or vertical
alignment.
2. Manual mode:
The device can be tilted as desired. The laser beam is projected at
an appropriate angle.
3. Grade mode:
Grading angles can be manually set in this mode. The laser can
be adjusted ±12 degrees in a single axis. If performing dual-slope
operation, the max range in the secondary axis may be restricted.
BLUETOOTH
PAIRING
TM
The laser automatically connects to the last paired devices when it is
switched on. If the laser does not fi nd a device or if it is to be paired
with a new device, perform the pairing manually.
It is recommended that the laser is paired with the remote and
detector to use the laser to its full potential.
Remote
To INITIATE PAIRING on the Remote or Laser, select the pairing
icon from the device's main menu. Use the up/down arrow buttons to
select "Add Device," then press the OK button to confi rm.
To PAIR devices, fi rst, initiate pairing from the Remote or Receiver,
then from the Laser. Once the connection is successful, an audible
tone will sound. Note that a Laser can be paired to 1 remote and
2 detectors at a given time. Attempting to pair an additional device
may result in disconnecting a diff erent device.
To UNPAIR devices, select the pairing icon from the laser or remote
main menu. Use the up/down arrow buttons to select the device you
wish to unpair. Press the OK button to confi rm, then press the OK
button again to unpair the device.
To unpair all devices from a laser, select the pairing icon from the
laser main menu, and use the up/down arrow buttons to select
"Unpair All." Press the OK button, then press the OK button again

HINTS FOR A TROUBLE-FREE PAIRING:
• The laser should be placed on a stable surface, so that pressing a
button does not cause a bump alarm.
• The laser has completed its leveling process.
• The detector must not detect a laser beam or artifi cial lightning.
• The laser and the detector should be in close proximity.
• Make sure there is no interference from other transmitting devices
such as phones, screen, computers, etc.
• Powering off the devices before attempting to pair again.
• After powering on, initiate pairing from the detector fi rst, then
quickly start pairing from the laser.
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, and the temperature warning will appear on the screen.
The laser beam turns off . The laser will automatically turn off after 5
minutes of this alarm.
When the tool reaches normal operating temperature (see technical
data), the tool will start the self-leveling process.
INFORMATION SCREEN
The information screen is useful for tracking operating hours, drop
events detected, and temperature events detected.
Choose information scree with the button
Press both button simultaneously
CLEANING
Wipe the aperture lens and the body of the laser with a clean soft
cloth. Do not use solvents.
Although the laser is dust and dirt resistant to a certain degree,
do not store in dusty places as long term exposure may damage
internal moving parts.
If the laser is exposed to water, dry the laser level before returning it
to the carrying case to prevent corrosion damage.
TROUBLESHOOTING
Startup Failure
If the Laser displayed "CAL. ERROR" warning immediately after
powering on the tool, this is an indication of a system error, return
the tool to an authorized MILWAUKEE service center.
Leveling Error
The leveling error screen appears, and the alarm will sound.
Ensure that the laser is on a level surface and the job site is clear
of obstacles. 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 parallel to the ground. Try the auto-leveling
process again, or power cycling the laser to clear the setting. If this
fails, return the laser to an authorized MILWAUKEE service center.
Slope Error
A slope error will occur if the combination of the adjusted grade
and the laser incline is set up to exceed the laser core's leveling
limitations. Pressing the grade, or OK buttons will clear the warning
and start the self-leveling sequence. Once Level, the laser or remote
will display the home/grade screen with values set to 0. The laser is
now in auto mode. Ensure the laser is on a level surface and check
that the desired slope is within manufacturing specifi cations before
attempting to slope the laser again.
on the detector.
General Alarm
See Manual will Flash on the screen and an alarm tone will play.
Return the tool to an authorized MILWAUKEE Service Center.
Bump alarm too sensitive
Ensure the laser is on a level, and on a stable surface. Try changing
to a less sensitive setting using a paired detector/ receiver. If this
fails, return the laser to an authorized MILWAUKEE service center.
Temperature alarm
If the temperature screen appears, ensure laser is within the
operating temperature range. Note that the internal temperature of
the tool maybe be 5° - 10° warmer than the ambient temperature.
will appear.
ONE-KEY™ lock out
The laser will turn on briefl y, but shut down after ~15 seconds. The
ONE-KEY™ LED will be fl ashing red. This is an indicator that the
laser is locked out. Use the ONE-KEY™ app to connect and unlock
the tool.
Pairing failure
Ensure the detector/receiver is powered on, within the distance
range and in Pairing Mode.
NOTE: If all the recommended trouble shooting fails, power cycle
the 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 CHECK
Perform the accuracy check procedure immediately upon unboxing
of each new laser and before exposure to jobsite conditions.
The following accuracy checks must be performed:
1. Leveling accuracy for horizontal orientation
2. Leveling accuracy for vertical orientation
3. Plumb dot accuracy.
For more detailed information see picture section.
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.
Infl uences on Accuracy
fo reset.
Ambient temperature changes can impact laser accuracy. For
accurate and repeatable results, the described procedures should
be done with the laser off the ground and placed in the center of the
working area.
Mount the laser on the tripod and check the leveling of the tripod.
Abusive treatment of the laser, such as excessive impacts from
drop, can also lead to changes in product accuracy. Therefore, it is
recommended to perform the accuracy check procedure after any
drops or before completing any critical jobs.
NOTE: Extreme temperatures will aff ect laser accuracy.
MAINTENANCE
This laser will require a calibration service after a period of 12
months.
Use only Milwaukee accessories and Milwaukee spare parts. Should
components need to be replaced which have not been described,
please contact one of our Milwaukee service agents (see our list of
