11.3 Slurry Cup Maintenance
1.
Check the slurry cup after every test to be certain the threads are not
contaminated with cement. Lubricate the threads with grease prior to the
start of every test.
2.
It is recommended that hardened cement slugs be pressed out, rather than
pounded out with a hammer. Pressing tends to cause less damage. When
pressing the slug out, be careful not to damage the paddle shaft point or the
paddle itself. If the slug is not pressed out straight, it may cause the cup
sleeve to become oval and prevent the threaded closures from threading into
the sleeve.
