The maximum permissible error is 3 mm at 10 m.
Example:
d1 = 6 mm/d2 = 4 mm/room length (D) = 10 m.
Points 1 and 3 are on different sides of the exact horizontal.

8.3 Checking the angle between the front beam
and the perpendicular beam
1. Place the tool on a smooth, horizontal surface at the
edge of a room with a length of at least 10 m and
width of at least 5 m.
2. Switch on all four beams.
3. Fix a target plate (#1) at a distance of at least 10 m
from the tool so that the front beam strikes exactly
the center of the target plate.
4. Using a second target plate, mark a reference cross
on the floor at a distance of 5 m (measure the dis-
tance) from the first target plate. The beam must
strike the second target plate exactly in the center
(cross-hairs).
5. Fix a target plate (#2) at a distance of 5 m from the
reference cross so that the front beam strikes exactly
the center of the target plate.
9. Care and maintenance
9.1 Cleaning and drying
Blow dust off the glass.
●
Do not touch the glass with your fingers.
●
Use only a clean, soft cloth for cleaning. If neces-
●
sary, moisten the cloth slightly with pure alcohol or
a little water.
-NOTE-
Do not use any other liquids as these may damage
●
the plastic components.
Observe the temperature limits when storing your
●
equipment. This is particularly important in summer
if the equipment is kept inside a motor vehicle
(–20 °C to + 63 °C/–4 °F to 145 °F).

= 1 mm/10 m
6. Now position the tool with the lower plumb beam
exactly on the center of the reference cross so that
the front beam strikes exactly the center of target
plate 1. The tool is exactly 5 meters from the two
fixed target plates.
7. Mark the position (d1) of the perpendicular beam
with a target plate at a distance of 5 m (fix the tar-
get plate in position).
8. Pivot the tool to the right through 90°. The lower
plumb beam must remain in the center of the refer-
ence cross. The perpendicular beam must strike
target plate 2 exactly in the center (cross-hairs).
9. Mark the position (d2) of the front beam on the target
plate which is still fixed at a distance of 5 meters.
-NOTE-
The horizontal distance between d1 and d2 must be
no greater than 3 mm at a working distance of 5 m.
8.3.1 Calculation of accuracy (g) at a working
distance other than 5 m
g = (3 mm x working distance (m))/5 m.
In this case, the horizontal distance between d1 and
d2 must not exceed the value (g) at the defined work-
ing distance (m).
9.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at maximum 40 °C/104 °F). Repack
the equipment only once it is completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation. Remove
the batteries if the tool is not used over a long period.
Leaking batteries may damage the tool.
9.3 Transportation
Use the Hilti shipping carton, Hilti toolbox or packag-
ing of equivalent quality for transporting or shipping
your equipment.
-NOTE-
Always remove the batteries before shipping.
