•  Before starting a measurement, make

sure you find a stabile position with two
feet on a solid base. Do not bend over
into the machine. If you must lean
against a safety fence (or something
similar), first check its stability.

•  Always follow the safety instructions that

apply for the location where the 
measurements are done. Do not ignore 
or remove safety constructions from the 
paper machine.

Please note:

Doing measurements (of any kind) on running paper
machines is dangerous and requires alertness, concen-
tration and common sense. The Feltest instruments are
designed and constructed to be as save as possible for

their intended use. Nevertheless it is the user's responsibility to
actually use the instrument in a safe way. Feltest Equipment bv can
not be held responsible or liable in any way for suffered injuries or
damages that occurred while using their instruments.
