Parallel Aligning of a Rotational Plane
(see figure G)
When the measuring tool is in the vertical posi-
tion, the rotational plane can be aligned parallel
to a reference line (e.g. a wall). For this, position
the measuring tool as close as possible to the ref-
erence line and select rotational operation.
Align the rotational plane approximately parallel
to the reference line. For this, rotate the rota-
tional plane around the Y-axis using the left 21
and right 24 direction pushbuttons. For easier
alignment, the rotational plane can be brought
into proximity with the reference line. For this,
incline the rotational plane around the X-axis us-
ing the upper 20 and lower 23 direction push-
buttons. Now, align the rotational plane exactly
parallel to the reference line by rotating it
around the Y-axis using the left 21 and right 24)
direction pushbuttons. When no direction push-
button is pressed for 5 seconds, the rotational
plane is automatically aligned vertical again.
Projecting Plumb Points to the Ceiling
The plumb notches 10 and 11 are located at the
bottom edge of the housing. They are used for
precise alignment of the plumb beam above a
floor point. Mark two right-angled auxiliary lines
through the floor point. Set up the measuring tool
in the horizontal position and bring it into align-
ment with the auxiliary lines using the plumb
notches.
Working with tripod: When the measuring tool is
in the horizontal position, the laser origin is locat-
ed directly above the horizontal tripod mount.
When using a tripod 40 (accessory), a plumb bob
can be attached to the tripod fastening screw and
used for alignment of the laser to the floor point.

Contouring Gradients (see figure H)
When contouring gradients, the automatic level-
ling must be switched off (see "Working without
Automatic Levelling"). Afterwards, the measur-
ing tool can be set up in any inclined position.
When contouring gradients in only one axis di-
rection (e.g. hill flanks or slopes) and when the
measuring tool is in the horizontal position, it is
recommended to select inclined operation in a
single axis – (see "Switching Off the Automatic
Levelling in the Horizontal Position/Inclined Op-
eration in a Single Axis"). In this case, align the
measuring tool with the Y-axis parallel to the di-
rection of the incline or slope.
For contouring of precise gradients, it is recom-
mended to use an inclination gauge 37 (acces-
sory) which is mounted onto a tripod 40.
It is also possible to align the measuring tool
parallel to the required incline by underlaying on
one side or with use of the tripod 40 (acces-
sory). Within the self-levelling range of 8 %,
inclines can also be adjusted with the direction
pushbutons.
