Assembly
Inserting/Replacing the Batteries (see figure A)
Alkali-manganese batteries are recommended for the measuring tool.
To open the battery lid 9, slide it in the direction of the arrow away from the battery
compartment. Insert the batteries provided. When inserting, pay attention to the cor-
rect polarity according to the representation on the inside of the battery compart-
ment.
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.
Operation
Initial Operation
 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or variations in
temperature. As an example, do not leave it in vehicles for 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 temperature, 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.
Switching On and Off
To switch on the measuring tool in line operation, push the On/Off switch 1 to the
"—" position and in point operation to the "" position. Immediately after switching
on, the measuring tool sends a laser beam out of outlet opening 5 (line operation) or
10 (point operation), depending on the selected operating mode.
 Do not point the laser beam at persons or animals and do not look into the la-
ser beam yourself, not even from a large distance.
To switch off the measuring tool, push the On/Off switch 1 to the centre position.
 Do not leave the switched on measuring tool unattended and switch the mea-
suring tool off after use. Other persons could be blinded by the laser beam.
When not using the measuring tool, switch it off in order to extend the battery life.
