Product Description And Specifications; Intended Use; Product Features - Bosch GMS 120 Professional Manual Original

Do not use the measuring tool in explosive atmospheres which contain flam-
u
mable liquids, gases or dust. Sparks may be produced inside the measuring tool,
which can ignite dust or fumes.
The measuring tool may not be 100 % accurate for technological reasons. To
u
eliminate hazards, familiarise yourself with further sources of information, such
as building plans and photographs taken during construction, etc. before carry-
ing out any drilling, sawing or routing work on walls, ceilings or floors. The accur-
acy of the measuring tool may be affected by environmental influences, such the level
of humidity or there being other electronic devices nearby. The structure and condi-
tion of the walls (e.g. damp, building materials containing metal, electrically conduct-
ive wallpaper, insulating materials, tiles) and the number, type, size and position of
the objects may distort the measuring results.
Make sure that you are properly earthed when taking measurements. If you are
u
not properly earthed (e.g. by wearing insulating footwear or by standing on a ladder),
it will not be possible to locate live cables.
If there are gas pipes in the building, check to ensure that none of them have
u
been damaged after completing any work on walls, ceilings or floors.
Live wires can be detected more easily when power consumers (e.g. lamps, appli-
u
ances) are connected to the wire being sought and switched on. Switch off power
consumers and make sure that live cables are de-energised before drilling, saw-
ing or milling into walls, ceilings or floors. After performing any kind of work,
check to ensure that objects placed on the base material are not live.
When attaching objects to dry walls, and in particular when attaching them to
u
the substructure, check to ensure that both the wall and the fastening materials
have a sufficient load-bearing capacity.
