Assembly

Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the meas-
uring tool.
To open the battery compartment 3, turn the latch 2 in clock-
wise direction to position and pull off the battery lid.
Insert the batteries provided. When inserting, pay attention
to the correct polarity according to the representation on the
inside of the battery compartment.
Position the battery lid to the bottom of the housing and then
push it upward. To lock the battery lid, turn the latch 2 in anti-
clockwise direction to the position.
When the laser beams flash slowly during operation, the bat-
teries are low. When the flashing begins, the measuring tool
can be operated for approx. 8 h.
Always replace all batteries at the same time. Only use batter-
ies 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-dis-
charge.

Initial Operation

3 601 K66 1..
 Protect the measuring tool against moisture and direct
30 m
sun light.
±0.3 mm/m
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for a long time. In case of large vari-
±5°
ations in temperature, allow the measuring tool to adjust to
±3° the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
<4 s
ture, the accuracy of the measuring tool can be impaired.
–10 °C...+40 °C
 Avoid heavy impact to or falling down of the measuring
–20 °C...+70 °C
tool. Damage to the measuring tool can impair its accura-
90 %
cy. After heavy impact or shock, compare the laser lines or
2 plumb beams with a known horizontal or vertical reference
line or with already checked plumb points.
635 nm, <1 mW
 Switch the measuring tool off during transport. When
1/4"
switching off, the levelling unit, which can be damaged in
3 x 1.5 V LR06 (AA)
case of intense movement, is locked.
24 h
Switching On and Off
To switch on the measuring tool, push the On/Off switch 4
0.25 kg
upward so that "I" is indicated on the switch. Immediately af-
ter switching on, the measuring tool sends a laser beam out of
104 x 40 x 80 mm
each exit opening 1.
IP 5X
 Do not point the laser beam at persons or animals and
do not look into the laser beam yourself, not even from
a large distance.
 Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
To switch off the measuring tool, push the On/Off switch 4
downward so that "0" is indicated on the switch. When
switching off, the levelling unit is locked.
Setting the Automatic Switch-off
By default, the measuring tool automatically shuts off
20 minutes after being switched on.
The automatic switch-off can be set from 20 minutes to
8 hours. For this, switch the measuring tool on, then immedi-
ately off, and then on again within 4 s. To confirm the change,
all laser beams will flash quickly for 2 s after switching on the
second time.
 Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. Other
persons could be blinded by the laser beam.
When switching on the measuring tool the next time, the auto-
matic switch-off is set to 20 minutes again.
Working with Automatic Levelling
Position the measuring tool on a level and firm support, attach
it to the holder 8 or to the tripod 18.
After switching on, the automatic levelling function automati-
cally compensates irregularities within the self-levelling range
of ±5° (longitudinal axis) and ±3° (lateral axis). The levelling
is finished as soon as the laser points do not move any more.
