Hand-Operated Hydraulic Pump 10
Install Specimen in the Grips
Perform the following procedure to mount a specimen in the grips. Ensure that all
grip parts are sufficiently cool before touching them.
Specimen mounting is a potentially hazardous procedure because hydraulic
pressure is applied to the system and actuator movement is required.
This can cause personal injury. It can also apply damaging forces to the
specimen, furnace, or to other fixtures.
Use extreme care while performing the following steps. Always use your load
frame’s low velocity control (if equipped).
1. Determine the hydraulic pressure that must be applied to the grips in order
to adequately grip the specimen.
2. Install the specimen using the procedure provided in the specific grip
product manual.
3. When satisfied that the specimen is properly installed, actuate the hand-
operated pump until the required hydraulic pressure is shown on the
pressure gage.
Remove Specimen from the Grips
1. Turn the hydraulic hand pump pressure release valve counterclockwise until
the pressure indicated on the pressure gage reads zero. This allows either the
grip piston or wedge springs to release the specimen.
2. Remove the specimen using the procedure provided in the specific grip
product manual.
