or damage to the instrument.

Precautions

If this instrument is used in a manner not specied 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 ammable gases at the temperatures to which they are subjected to during the

I.6 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, perbunane, silicone, stainless steel surfaces) must

not be damaged or subject to chemical action by the cleaning uid.

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 bers, 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.
