Hilti PS 85 Bedienungsanleitung Seite 17

▶ While scanning is in progress, do not wear gloves and ensure an adequate
earth/ground connection. An inadequate earth/ground connection can
impair material detection (including detection of electrically live lines).
▶ Always move the measuring tool back and forth with a perfectly steady
action.
▶ Do not drill at positions where the measuring tool has detected the
presence of an object. Take the diameter of the drill bit into account and
always allow an adequate safety factor.
▶ Do not use the measuring tool to detect critical objects such as load-
bearing structural elements, high-tension lines, gas or steam lines,
high-pressure lines and similar objects.
▶ Never rely on the measuring tool alone. Verify the results of measure-
ments by cross-checking with other sources of information and by taking
control measurements and, if necessary, by drilling pilot holes.
▶ Make sure that the wrist strap is securely attached. Prior to each
use, always check the attachment point of the wrist strap for possible
damage.
▶ Risk of injury by falling tools and/or accessories. Use only the wrist strap
supplied.
▶ Carry the measuring tool only by the grip provided for the purpose. Keep
the grip clean, dry and free from oil and grease.
▶ Keep the display clean and easily readable. Wipe the display only with a
clean, non-scratch cloth.
▶ Due to the measuring principle employed, the results of measurements
can be negatively affected by certain ambient conditions. These include,
e.g. proximity to devices that generate powerful magnetic or elec-
tromagnetic fields, dampness, construction materials containing metal,
aluminum foil-backed insulation, multiple layers, materials with cavities
or electrically conductive wall coverings or tiles. Accordingly, other
sources of information (e.g. plans of the building) should also be con-
sulted before beginning drilling, sawing or grinding in the area scanned.
▶ When scanning is in progress, avoid the vicinity of devices (such as
cellphones, for example) that emit strong electric, magnetic or electro-
magnetic fields. On all devices capable of producing emissions that
can impair measurement, deactivate the relevant functions if possible,
or switch the devices off.
▶ Do not operate the measuring tool in the vicinity of military installations,
airports, radio astronomy facilities or in aircraft unless prior permission
has been obtained.
▶ Check the accuracy of the measuring tool if it has been dropped or
subjected to other mechanical stresses. If the measuring tool is damaged,
have it repaired by a Hilti service center.
▶ The specified operating and storage temperatures must be observed.
