I.5 Safety Symbols and Precautions
Safety Symbols
The following explains safety symbols which may be found in this operating manual.
Refer to the manual for specific warning or caution information to avoid personal injury
or damage to the instrument.
Precautions
If this instrument is used in a manner not specified by the manufacturer, the protection
provided by the instrument may be impaired.
This instrument is not intended for use in a potentially hazardous environment.
The user should ensure that the substances placed under test do not release poisonous,
toxic or flammable gases at the temperatures to which they are subjected to during the
testing.
I. Cleaning
Great care should be given to cleaning of the sample tube, the locking plugs and the balls. These
components (material: glass, Ni-iron, steel, perbunan, silicone, chromium-plated surfaces) must
not be damaged or subject to chemical action by the cleaning fluid.
The cleaning procedure is to be carried out in the following sequence:
• The viscometer is pulled out of the bearing guide (14) in the stand by turning it 90° and
placed in a suitable collecting basin.
• Unscrew the caps and remove the locking plugs in such a way that the ball does not fall into
the collecting basin (possibly damaging the ball). The ball collector (Part No. FB23) is an
optional item that can be purchased on request.
• Clean the sample tube using a suitable cleaning agent for the material being measured with
the cleaning brush (Part No. FB53).
• There must not be any residue remaining in the sample tube or on the balls after they have
been cleaned and are dry. Wipe with a Kim wipe or cloth that will not leave fibers, if neces-
sary.
• When cleaning, be careful that the cleaning agent does not come into contact with the equip-
ment outside of the measuring tube (potential for varnish damage).
