Telescoping rod
(accessory, e. g. Bosch BLM 260)
When working in terrain, to check evenness or to project
gradients, it is recommended to use the telescoping
rod 29 together with the Bosch BLE 100 receiver (ac-
cessory).
A relative millimeter scale (±50 cm) is marked on the top
of the telescoping rod (accessory).
Its zero height (90 ... 210 cm) can be selected on the ex-
tension. In this manner, deviations from the reference
value can be read off directly.
Marking Right Angles
Align the laser beam in the vertical position parallel to
the reference line (tile edge, wall) without the deflection
prism 4. Then attach the deflection prism 4.
The right angle is indicated by the deviated laser beam.
☞
Occasionally check for unintentional position
changes of the unit from the parallel alignment,
caused by taking off the deflection prism 4.
Handling the deflection prism becomes unnecessary
when using the dual-beam prism (accessory), as the la-
ser beam is divided into two right-angled beams, with
both beams visible at the same time.
Marking Plumb Lines
Position the unit with the deflection prism 4 in the verti-
cal position anywhere in front of e. g. a wall and project
the laser point/beam onto the spot, where the plumb line
is to be marked. Select point or rotational operation and
mark the plumb line.
Indicating Vertical Planes
(Partitions, Joint Cuts)
Position the unit with the deflection prism 4 in such a
matter, that the laser point exactly matches the refer-
ence line, e. g. the partition. Then remove the deflection
prism 4 and align the laser beam parallel to the refer-
ence wall (see Section “Parallel Alignment”). Replace
deflection prism 4 again. Select point or rotational oper-
ation and mark the beam points.
Projecting a Plumbed Laser Point
to the Ceiling
For exact alignment of the plumb beam (laser) over the
floor point, centering marks 8 are located at the lower
edge of the housing. For this, mark two right-angled
auxiliary lines (crosshairs) through the floor point and
align the unit with the centering marks 8.
Parallel Alignment
If right angles are to be marked or partitions to be
aligned, then align the laser beam parallel, meaning with
the same distance to the reference line (wall, expansion
joint).
For this, set up the unit without the deflection prism in
the vertical position, flush to the wall. Position the
measuring plate 31 as close as possible in front of the
unit. Manually align the unit, so that the laser point
projects onto the center of the thick black line. Fine ad-
just with the direction push-buttons 9 and 10 or with the
remote control 27 (accessories).
Then set the measuring plate 31 at the end of the wall
(at the same distance) and position the laser beam with
the direction push-buttons (or with the remote control 27
(accessory)) in such a manner, that it projects onto the
center of the same black line, thus running parallel to the
wall. This can be viewed well from the unit, as the laser
beam is reflected weaker from the thick black line, mak-
ing it appear darker.
The laser beam can be aligned comfortably from the
point of aim within the range of ±10 % (±6°), with use of
the remote control 27 (accessory) and e. g. and a rule.
Working with the measuring plate
With the measuring plate 31 the laser beam can be pro-
jected onto the floor or the laser height onto the wall.
With the square zero field and the scale, the offset to the
desired height can be measured and marked at other
positions. In this manner, the adjustment of the unit to
the exact height to be marked is not necessary.
☞
Always use the middle of the laser points for
marking since the size of the point changes with
the distance.
The measuring plate has a reflective coating for better
visibility of the laser beam over larger distances or when
the incidence of the sun is high.
The amplification of light intensity can only be seen
when viewing from the unit, therefore look alongside the
laser beam towards the measuring plate.
