Maintenance and Service
Maintenance and Cleaning
Check the measuring tool before each use. If the measuring tool is vis-
u
ibly damaged or parts have become loose inside the measuring tool, safe
function can no longer be ensured.
Always keep the measuring tool clean and dry to ensure optimum, safe oper-
ation.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a dry, soft cloth. Do not use any detergents or
solvents.
Bosch Power Tools
Corrective measures
Only use the measuring tool when the humidity
has been low for a few days and the wall is not
damp.
Apply voltage to the cable, e.g. by turning on the
corresponding light switches. It is not possible
to reliably detect multi-phase electricity cables
and cables with voltages outside the 110−240 V
and 50−60 Hz range.
The detection depth depends on the building
material and may be less than the maximum de-
tection depth.
Be sure to look at the metal object display to find
the metal pipe.
Grip the measuring tool firmly without gloves.
Do not stand on insulating ladders or scaffolds.
Do not wear insulating footwear.
Detection will not be reliable in the presence of
metallic building materials or building materials
that are too dry or too damp (e.g. if the humidity
is too low or too high).
