7.4 Deactivating the inclined plane
function
The inclined plane function can be deacti-
vated by pressing a special key combina-
tion. The inclination adjustment keys are
then no longer active.
The deactivation procedure is started with
the tool switched off.
Procede by pressing the following key
combination:
– Press and hold down the Y- and the
shock warning keys simultaneously and
then press the on /off button.
Subsequently press the Y+ button within
10 seconds (release the other keys
before pressing the Y+ key).
The inclined plane function can be reacti-
vated when required. This is done by
pressing the same key combination once
again.
8. Hilti calibration service
We recommend that the tool is checked by
the Hilti calibration service at regular inter-
vals in order to verify its reliability in
accordance with standards and legal
requirements.
Use can be made of the Hilti calibration
service at any time, but checking at least
once a year is recommended.
The calibration service provides confirma-
tion that the tool is in conformance, on the
day it is tested, with the specifications
given in the operating instructions.
If deviations from the manufacturer's
specification are found, the tool is then
re-adjusted. After checking and adjustment,
a calibration sticker applied to the tool and
a calibration certificate provide written
verification that the tool operates in
accordance with the manufacturer's
specification.
Calibration certificates are always required
by companies certified according to ISO
900x.
Your local Hilti center or representative will
be pleased to provide further information.
8.1 Checking horizontal rotation
Horizontal alignment of the tool in the X- or
Y-directions can be checked as follows:
8.1.1 Checking
1. Set up the tool in the horizontal plane at
a distance of about 20m (65 ft) from a
wall (can also be carried out with the
tool set up on a tripod).
2. With the aid of the laser detector, make
a mark on the wall.
3. Pivot the tool through 180° about its
own axis (check the same laser axis).
4. With the aid of the laser detector, make
a second mark on the wall.
If the check has been carried out carefully,
the distance between the marks A and B
should be less than 2 mm / 0,15 inch (at
20 m / 65 ft from the wall).
In the event of a deviation in excess of
this, please return the tool to a Hilti Service
Center for inspection.
