Care And Maintenance - Hilti PS 38 Mode D'emploi

6.3.6 Unclear signals
If a large number of objects are indicated in the standard
display area, there can be two reasons for this.
1. The wall probably contains a large number of cavities
(hollow brick).

7 Care and maintenance

7.1 Cleaning and drying
1. Use only a clean, soft cloth for cleaning. If necessary,
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.
2. The temperature limits for storage of your equipment
must be observed, especially in winter / summer.
7.2 Storage
Put the tool into storage only when dry. Please observe
the applicable temperature limits when storing the tool.
Check the accuracy of the equipment before it is used
after a long period of storage.
Remove the batteries from the tool before storing it for a
long period. Leaking batteries may damage the tool.
7.3 Transport
Use the Hilti toolbox or equivalent packaging when trans-
porting the tool.
Switch to "Hollow brick" mode. Most of the cavities will
then no longer be shown in the display.
If too many objects are still shown, several scans must be
made at different heights and the position of the objects
detected marked on the wall.
Offset marks tend to indicate cavities while marks in a
line tend to indicate an object.
2. The scan has been made longitudinally, i.e. along the
length of an object. In this case, move the tool up or
down and repeat the scan (see fig. 6 on the cover pages).
CAUTION
Always remove the batteries before shipping the tool.
7.4 Hilti Calibration Service
We recommend that the tool is checked by the Hilti Cal-
ibration Service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
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 confirmation that the
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
After checking, a calibration sticker applied to the tool and
a calibration certificate provide written verification that the
tool is operating 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.
