Removing Specimen
To remove a round or flat specimen from the grips:
1. If not applied, apply system hydraulic pressure to the load unit.
2. Release the upper and lower grips.
3. Remove the specimen.
If the specimen is not fractured, it may be necessary to adjust the position of
the actuator.
If the specimen is installed in threaded collets, proceed as follows:
A.
Using a spanner wrench, unthread the collet retainer from the upper
grip.
B.
Adjust the position of the actuator away from the upper grip. Remove
the collet retainer and threaded insert from the specimen.
C.
Using a spanner wrench, unthread the collet retainer from the lower
grip.
D.
Remove the specimen from the lower grip and the threaded insert from
the specimen.
Specimens can create debris that can settle in the grips.
Debris in the grips can cause damage to the grips.
Clean any debris out of the grips before installing a new specimen.
