Working Advice

General Information
The reception lens 7 and the laser beam outlet 8 must not be covered when taking a
measurement.
The measuring tool must not be moved while taking a measurement. Therefore, place
the measuring tool, as far as this is possible, against or on a firm stop or supporting
surface.
Influence Effects on the Measuring Range
The measuring range depends on the lighting conditions and the reflective properties of
the target surface. For better visibility of the laser beam in extraneous light, use the laser
viewing glasses 10 (accessories) and the laser target plate 9 (accessories) or shade the
target area.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when measuring on
different surfaces. Included here are:
– transparent surfaces (e.g., glass, water),
– reflecting surfaces (e.g., polished metal, glass),
– porous surfaces (e.g. insulation materials),
– structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 9 (accessory) on these surfaces.
Furthermore, faulty measurements are also possible when sighting inclined target
surfaces.
Bosch Power Tools
Press and hold the measuring button 2. When the cursor
is on the desired setting, release the measuring button
2. After releasing, the measuring tool switches itself on
with the selected setting.
