Check Agitation System and Bag Suspender
The agitation system and bag suspender should be checked every three to six months or if fiber values are higher
than normal or inconsistent.
IMPORTANT
Poor agitation will cause higher analysis values and poor repeatability.
To check the stroke of the agitation system, follow the procedure detailed below.
1. Place a full bag suspender in the Vessel (without
the bag suspender weight), but add NO water.
2. Remove the top from a dark felt tip marker.
3. Lay the marker horizontally on the top of the bag
suspender so that the tip touches the inside wall of
the Vessel.
4. With constant downward pressure on the marker,
hold the pen in place so that it rides the top tray up
and down as you execute the Flush Procedure.
(See the Flush Procedure section of this manual
for details.)
5. Allow the bag suspender (& pen) to move up and
down three or four times as the pen marks the
Vessel wall.
6. Stop the agitation.
7. Remove the pen and the bag suspender.
8. Measure the mark on the Vessel wall. It should be
½ inch long. If the motion is less than ½ inch, you
will need to replace either the Bag Suspender Tip
(see next page) or the agitator (because the old
disc has flattened).
To test the agitator vertical positioning, follow the procedure detailed below.
1. Place the bag suspender weight on the bag
suspender within the Vessel.
2. Place a straight edge across the top of the Vessel
as shown in the picture.
3. Run the Flush Procedure. (See the Flush
Procedure section of this manual for details.)
4. The weight should not hit the straight edge at the
top of the stroke. If the weight is hitting the lid or
traveling above the top of the Vessel, the agitator
has moved up in the Vessel and must be
completely re-seated at the bottom of the Vessel.
