Preparation
Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the measuring tool.
– Fold open the battery lid 7and insert the batteries. When inserting,
pay attention to the correct polarity according to the representation on
the inside of the battery compartment.
If the batteries become weak, the battery capacity indicator 3will flash
green. The laser lines will also flash every 10 mins for approx. 5 s.
The measuring tool can be operated for approx. 1 hour after the first
flashing. If the batteries become empty, the laser lines will flash again
before automatic shutoff.
Always replace all batteries at the same time. Only use batteries from
one brand and with the identical capacity.
Remove the batteries from the measuring tool when not using it for
extended periods. When storing for extended periods, the batteries
can corrode and self-discharge.
Working with the BM3
(see figures A – G)
The L-bracket 16 of the BM 3 17 provides easy ability to properly posi-
tion the laser line or lines.
It attaches to job site surfaces as follows:
– To drywall or wood walls using No. 8 screws
– To sit on the floor using retractable feet
– To steel studs using the magnets on the back
– To ceiling grid rails using the clip functionality
It can also be used as a mini tripod.

-17-
Initial Operation
Protect the measuring tool against moisture
and direct sun exposure.
Do not subject the measuring tool to extreme temperatures or
variations in temperature. For example, do not leave it in vehicles
for a long time. In case of large variations in temperature, allow the
measuring tool to adjust to the ambient temperature before putting it
into operation. In case of extreme temperatures or variations in tem-
perature, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool.
Damage to the measuring tool can impair its accuracy. After heavy
impact or shock, compare the laser lines with a known horizontal or
vertical reference line.
Switch the tool off during transport. Slide the On/Off switch 2to
the “Off” position when transporting the measuring tool. This locks the
leveling unit, which can be damaged in case of intense movement.
Operation
•To attach the laser tool, screw the 1/4”-20 mount 13 into the tool
and tighten. Turn the knob and tool together as necessary to properly
position the laser line or lines.
•To adjust the height of the laser lines, adjust the height using the
adjustment knob on the ceiling grid clip 18 of the BM 3 17.
Tip: It is recommended to clean the back of the L-bracket 16 before
mounting via the magnets to make sure you have the optimal mag-
netic hold of the tool on the mounting surface. Cleaning this will re-
duce the amount of interference from any dust or debris between the
magnets 15, L-bracket 16 and the mounting surface on the jobsite.

-18-
Switching On and Off
To save energy, only switch the measuring tool on when you are us-
ing it.
Do not leave the switched-on measuring tool
unattended and switch the measuring tool
off after use. Other persons could be blinded by the laser beam.
– To switch on the measuring tool, slide the On/Off switch 2to po-
sition “ ” (for working without automatic leveling) or to position
“” (for working with automatic leveling).
As soon as it is switched on, the measuring tool projects laser lines
from the exit openings 1.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a long distance.
– To switch off the measuring tool, slide the On/Off switch 2to posi-
tion “Off ”.
The pendulum unit is locked when the tool is switched off.
When exceeding the maximum permitted operating temperature of
122° F (+ 50° C), the measuring tool switches off to protect the laser
diode. After cooling down, the measuring tool is ready for operation
and can be switched on again.
Automatic Shut-off
When no button on the measuring tool is pressed for approx. 120 min-
utes, the measuring tool automatically switches off to save battery life.
– To switch the measuring tool back on after automatic shutoff, you can
either slide the On/Off switch 2to position “Off” first and then switch the
measuring tool back on, or press button 6.

-19-
Deactivating the Automatic Shut-off:
– To deactivate automatic shut-off, hold down button 6for at least
3 s with the measuring tool switched on. When automatic shut-off is
deactivated, the laser lines will flash briefly as confirmation.
Note: When the operating temperature exceeds 113° F (+ 45° C), the
automatic shut-off can no longer be deactivated.
Activating the Automatic Shut-off:
– To activate the automatic shut-off, switch the measuring tool off and
then on again.
Setting the Operating Mode (see figures B1–F1)
The measuring tool has several operating modes between which you
can switch at any time:
– Cross-line operation: The measuring tool generates a horizontal
and a vertical laser line facing frontward.
The laser lines cross at a 90° angle.
– Horizontal line operation: The measuring tool generates a horizontal
laser line facing frontward.
– Vertical line operation: The measuring tool generates a vertical laser
line facing frontward.
When the measuring tool is positioned in the room, the vertical laser
line is displayed on the ceiling beyond the upper laser point.
When the measuring tool is positioned directly against a wall, the
vertical laser line generates an almost completely allround laser line
(360° line).
All modes can be selected both with and without automatic leveling.

-20-
If the measuring tool is outside of the self-leveling range, the laser
lines will flash quickly.
If during work with automatic leveling you switch to the “working with-
out automatic leveling” mode (On/Off switch 2in position “ ”), the
first combination of this mode’s lines is always activated.
