temperaturesr variations in temperature. As an
example, do not leave it in vehicles for a 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.
u 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 line with a known horizontal or
vertical reference line.

When switching off, the levelling unit, which can be
damaged in case of intense movement, is locked.

to the "On" position. Immediately after switching on, the
measuring tool sends laser beams out of the exit openings 1.
u 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.
