Technical Data
Assembly
Inserting/Replacing the Battery
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
To open the battery lid 10, press on the latch 9 and fold the
battery lid up. Insert the batteries/rechargeable batteries.
When inserting, pay attention to the correct polarity accord-
ing to the representation on the inside of the battery lid.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
f Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and discharge themselves.
Operation
Initial Operation
f Protect the measuring tool against moisture and direct
sun light.
f Do not subject the measuring tool to extreme tempera-
tures 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 measuring tool to ad-
just to the ambient temperature before putting it into oper-
ation.
f Avoid heavy impact to or falling down of the measuring
tool. Damage to the measuring tool can impair its accura-
cy. After heavy impact or shock, compare the laser lines or
plumb beams with a known horizontal or vertical reference
line or with already checked plumb points.
f Switch the measuring tool off during transport. When
switching off, the levelling unit, which can be damaged in
case of intense movement, is locked.
Switching On and Off
To switch on the measuring tool, push the On/Off switch 7 to
the “On” position. Immediately after switching on, the meas-
uring tool sends out the two laser lines 1.
f 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.
To switch off the measuring tool, slide the On/Off switch 7 to
the “Off” position. When switching off, the levelling unit is
locked.
f 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.
Operating Modes (see figures A –E)
After switching on, the measuring tool is in cross-line operat-
ing mode with automatic levelling.
To change the operating mode, press the “Mode” button 6
until the requested operating mode is indicated by the corre-
sponding illuminated operating-mode indication 5.
