the spirit level, the laser line
on a transverse wall
does not necessarily run horizontal,
and is thus not suitable for levelling.
Vertical alignment
(see figure
D
): The laser outlet aperture for line operation
(5)
must
face upward and the aluminium supporting surface
(2)
of the measuring tool must face
to the side. Vertically align the measuring tool using the spirit level
(3)
. As an example,
you can align top and base cabinets alongside the vertical laser line.
Aligning to reference points
(see figure
E
): Turn the measuring tool to any required
angle in order to align the laser line alongside your reference points. In this manner, as an
example, picture frames can be hung parallel to a stairway or ceiling pitch.
Projecting/Checking Heights using the Laser Point (Point Operation) (see figure F)
Place the measuring tool on the holder
(14)
and align it horizontally.
Using the laser point, you can for instance line up plug sockets on different walls or hooks
on a coat rack to ensure they are all at the same height. To do this, rotate the upper sec-
tion of the wall holder
(14)
with the measuring tool, not the other way round. Take care
not to touch the measuring tool during turning, as this could displace the alignment.
Once turned, check the upper section of the holder
(14)
to establish whether the spirit
level for horizontal alignment
(4)
is still central. If this is not the case, realign the
holder
(14)
using the adjusting screw
(17)
as required, until the spirit level
(4)
is central
again.
Working with tripod (recommended): Align the laser beam to the required height. Pro-
ject or check the height at the target location.
Working without the tripod: Establish the height difference between the laser beam and
the height at the reference point. Apply or check the height difference measured at the
target location.
Checking Horizontal/Vertical Lines with the Spirit Levels (see figure G)
The measuring tool can also be used as a carpenter’s spirit level for checking vertical and
horizontal lines, for example to align a washing machine or a refrigerator. Position the
measuring tool with the aluminium supporting surface
(2)
on the surface to be checked.
When placing on horizontal surfaces, the aluminium supporting surface
(2)
must face
downward; when placing against vertical surfaces, the laser outlet aperture for line oper-
ation
(5)
must face upward.
Working Advice
u
Only the centre of the laser point or laser line must be used for marking.
The size
of the laser point/the width of the laser line changes depending on the distance.
