Working Advice

General Information
The reception lens 22 and the laser beam outlet
21 must not be covered when taking a measure-
ment.
The measuring tool must not be moved while
taking a measurement (with the exception of
the continuous measurement function and the
minimum/maximum measurement). Therefore,
place the measuring tool, as far as this is possi-
ble, against or on the measuring points.
Measurement takes place at the centre of the la-
ser beam, even when target surfaces are sighted
at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light
conditions and the reflection properties of the
target surface. For improved visibility of the
laser beam when working outdoors and when
the sunlight is intense, use the laser viewing
glasses 24 (accessory) and the laser target plate
25 (accessory), or shade off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements
cannot be excluded when measuring on differ-
ent 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 25 (acces-
sory) on these surfaces.
Also, air layers with varying temperatures or
indirectly received reflections can affect the
measured value.
Bosch Power Tools
Measuring with the Positioning Pin
(see figures C, F and G)
The positioning pin 15 is suitable for measuring
out of corners (diagonal within a space) or from
hard to reach areas, such as from roller-shutter
rails.
Slide the latch 16 of the positioning pin side-
ward in order to swivel out the pin.
Set the corresponding reference level for meas-
urements with the positioning pin by pushing
button 1.
The positioning pin 15 swivels back in again by
pushing it toward the housing to the stop. The
pin automatically locks in place.
Aligning with the Spirit Level
The spirit level 6 allows for simple levelling of the
measuring tool. This allows for easier sighting of
target surfaces, especially over longer distances.
In combination with the laser beam, the spirit
level 6 is not suitable for levelling.
Sighting with the Alingment Aid (see figure K)
With the alignment aid 8, sighting over larger dis-
tances is a lot easier. For this, look alongside the
aligning aid on the top side of the measuring tool.
The laser beam runs parallel to this line of sight.
Working with the Tripod (Accessory)
The use of a tripod is particularly necessary for
larger distances. Position the measuring tool
with the 1/4" thread 17 onto the quick-change
plate of the tripod 23 or a commercially available
camera tripod. Tighten the measuring tool with
the locking screw of the quick-change plate.
Set the corresponding reference level for meas-
urement with a tripod by pushing button 1 (the
reference level is the thread).
