Always replace all the batteries at the same time. Only use batteries from the same man-
ufacturer and which have the same capacity.
Take the batteries out of the measuring tool when you are not using it for a pro-
u
longed period of time. The batteries can corrode and self-discharge during pro-
longed storage in the measuring tool.
Operation
Starting Operation
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid substantial knocks to the measuring tool and avoid dropping it. Damaging
u
the measuring tool can cause accuracy to be compromised. If the laser line is subjec-
ted to a substantial knock or is dropped, check it by comparing it to a known hori-
zontal or vertical reference line.
Switching On/Off
To switch on the measuring tool in line operation, push the on/off switch (1) to the — po-
sition, and in point operation, push to the ● position. Immediately after being switched
on, the measuring tool sends a laser beam out of outlet aperture (5) (line operation)
or (11) (point operation), depending on the operating mode selected.
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
To switch off the measuring tool, push the on/off switch (1) to the centre position.
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be blinded by the laser beam.
Measuring functions
Note: The specified levelling accuracy applies for the alignment of the laser beam with
reference to the spirit levels for vertical alignment (3) and for horizontal alignment (4).
