Maintenance
The Model 680.01 High-Temperature Grips are designed to be used in high
temperature environments. After every use in a high temperature environment,
the specimen, the adapters, and grip extensions should be cleaned and lubricated.

Clean the Grips
Specimen adapters and the threaded ends of the grip extension rods should be
cleaned and lubricated after each use. Because they must be removed from the
grip before another specimen may be tested, the small amount of additional time
involved in wiping and re-lubricating the threads is worth while, especially when
the grips are repeatedly exposed to high-temperatures.
If grip cleaning procedures are not performed as recommended, the grips
may not operate properly.
When used repeatedly in high-temperature environments, grip parts can become
welded together if they are not properly maintained.
1. Loosen and remove all anti-galling compound from the threads of the
specimen adapters and also from the threads of the grip extensions. Use a
wire brush if necessary.
Many chemicals used for cleaning or as solvents, such as isopropyl alcohol,
are flammable and can be ignited by nearby objects at high-temperature.
This can cause burn injuries or cause larger fires that are dangerous to life
and property.
Make sure that the grips and nearby furnaces are cool before using any
flammable substances. Isopropyl alcohol may be used to loosen deposits that are
difficult to remove by wire brush alone.
2. If compressed air is available, blow any remaining debris from inside the
ends of the grip extensions.
3. Before re-installing the specimen adapters, apply anti-seize lubricant to the
threads of the adapters and grip extensions.
