Working Advice

Only the centre of the laser line must be used for
u
marking. The width of the laser line changes depending
on the distance.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable support surface
for measuring. Place the measuring tool with the 1/4" tripod
mount (3) on the thread of the tripod (23) or a conventional
camera tripod. Tighten the measuring tool using the locking
screw of the tripod.
Roughly align the tripod before switching on the measuring
tool.
Securing with the universal holder (accessory)
(see figures H−O)
Using the universal holder (13), you can secure the measur-
ing tool on vertical surfaces, pipes or magnetizable materi-
als, for example. The universal holder is also suitable for use
as a floor stand and facilitates height adjustment of the
measuring tool.
To secure the measuring tool to the universal holder (13),
screw the holder's 1/4" screw (15) firmly in the tripod
mount (3) on the measuring tool.
To turn or move the measuring tool on the holder, loosen the
1/4" screw (15) slightly.
When using the ceiling clip (14), fine adjustments can be
performed by moving the measuring tool up and down using
the rotary knob (17).
Roughly align the universal holder (13) before switching on
the measuring tool.
The measuring tool can be secured as follows using the uni-
versal holder (13):
– The universal holder (13) (without ceiling clip (14)) can
be attached to magnetic surfaces using the magnets (19)
(figure L).
– You can use the universal holder (13) (without ceiling
clip (14)) as a tabletop tripod by placing the holder on
the floor and folding out the holder's stabilising legs (20)
(figure M).
– The universal holder (13) (without ceiling clip (14)) can
be screwed onto dry walls or wood. To do this, insert a
(commercially available) fastening screw measuring at
least 50 mm long into the screw hole (18) in the holder
and screw it down firmly (figure N).
– The universal holder (13) can also be attached to ceiling
grid rails or wall rails using the locking mechanism (16)
on the ceiling clip (14) (figure O).
Laser Goggles (Accessory)
The laser goggles filter out ambient light. This makes the
light of the laser appear brighter to the eye.
Do not use the laser goggles (accessory) as protective
u
goggles. The laser goggles make the laser beam easier to
see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as
u
sunglasses or while driving. The laser goggles do not

provide full UV protection and impair your ability to see
colours.

Maintenance and Service

Maintenance and Cleaning

Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any de-
tergents or solvents.
The areas around the outlet aperture of the laser in particular
should be cleaned on a regular basis. Make sure to check for
lint when doing this.
Only store and transport the measuring tool in the case (24).
If the measuring tool needs to be repaired, send it off in the
case (24).
