Initial Operation
• Protect the tool against moisture and
direct sun light.
• Do not subject the tool to extreme
t e m p e r a t u r e s o r v a r i a t i o n s i n
temperature.
As an example, do not leave
it in vehicles for longer periods. In case of
large variations in temperature, allow the
tool to adjust to the ambient temperature
before putting it into operation. In case of
extreme temperatures or variations in
temperature, the accuracy of the tool can
be impaired.
• Avoid heavy impact or dropping of the
tool. After heavy exterior impact on the
tool, an accuracy check should always be
carried out before continuing to work (see
“Leveling Accuracy”).
• Switch the tool off during transport.
When switching off, the leveling unit is
locked to help prevent damage in case of
intense movement.
Switching On and Off
Do not point the laser
b e a m a t p e r s o n s
or animals and do not look into the laser
beam yourself, not even from a large
distance.
D o n o t l e a v e t h e
s w i t c h e d o n t o o l
unattended and switch the tool off after
use.
To switch on the measuring tool, slide the
On/Off switch 14 to position “On ” (for
working without automatic leveling) or to
position “On ” (for working with automatic
leveling). As soon as it is switched on, the
measuring tool emits laser lines from the exit
openings 1.
To switch off the measuring tool, slide the
On/Off switch 14 to position “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 minutes, the
measuring tool automatically switches off to
save the batteries.
To switch the measuring tool back on after
automatic shut-off, you can either slide the
On/Off switch 14 to position “Off” first and
then switch the measuring tool back on, or
press button 8.
Temporarily Deactivating Automatic
Shut-Off
To deactivate automatic shut-off, hold down
button 8 for at least 3 s with the measuring
tool switched on. If automatic shut-off is
deactivated, the laser lines will flash briefly as
confirmation.
Note: If the operating temperature exceeds
113°F (45°C), automatic shut-off can no
longer be deactivated.
After the next time the measuring tool is
switched off and on, the automatic shut-off will
be activated 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 and point operation: The
measuring tool generates a horizontal
and a vertical laser line facing frontward,
a vertical laser point facing upward and a
vertical laser point facing downward.
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.
If the measuring tool is positioned in the
room, the vertical laser line is displayed on
the ceiling beyond the upper laser point.
If the measuring tool is positioned directly
against a wall, the vertical laser line
generates an almost completely allround
laser line (360° line).
