Operation
Initial Operation
• Protect the tool against moisture.
• Do not subject the tool to extreme temperatures or variations
in 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.
DO NOT stare directly at the laser beam or project
the laser beam directly into the eyes of others.
Serious eye injury could result.
Setting Up the Tool (see figure A)
Position the tool at least 17 ft (5 m) away from the cross-line
laser. Switch on the pulsating function of the cross-line laser and
select horizontal or vertical operation.
Note: Do not select cross-line operation or else faulty indications
on the height of the laser beam can occur.
Position the tool in such a manner that the laser beam can reach
the reception area 9. Align the tool in such a manner that the la-
ser beam runs horizontally through the reception area (as shown
in the figure).
Switching On and Off
• A loud audio signal sounds when switching on the tool.
Therefore, keep the tool away from your ear or other people
when switching on. The loud audio signal can cause hearing
defects.
To switch on the tool, press the On/Off button 2. An audio signal
will sound and all LEDs will light up briefly.
To switch off the tool, press the On/Off button 2 again. An audio
signal will sound three times and all LEDs will light up briefly
before the tool switches off. The power indicator 3 turns off.
