  If the specimen slips while under load when using your Instron Power Tool, there are several potential causes. You might be using the wrong size or type of jaw face, so install the appropriate jaw faces for the specimen size and type. Ensure there's enough gripping area by installing the specimen for complete engagement with jaw faces. Check and adjust the air supply pressure to ensure enough gripping force. Worn jaw faces can also cause slippage, so replace them if needed. For 5kN and 10kN grips, ensure the jaw faces are adjusted correctly to the specimen width.

  If the jaw faces on your Instron Power Tool do not close on the specimen, several issues could be the cause. First, ensure that the air pressure supply is on. Then, toggle the foot switch and open the toggle switch. Check that the air hoses to the grips are not damaged and that all fittings and valves are clean and unobstructed. The grip may require lubrication; refer to “Lubrication” on page 53. If none of these steps work, the grip seal may be faulty, in which case you should replace it. For 5kN and 10kN grips, make sure the jaw faces are adjusted correctly.

Why does the specimen break at the jaw face when using my Instron Power Tool?

  Sylvia DavisAug 10, 2025
  If your Instron Power Tool specimen breaks at the jaw face, it could be due to several reasons. The initial gripping force might be too great for the specimen; reduce the air pressure to the grip and use taller jaw faces to distribute the clamping force over more of the specimen area. Also, check that you are using the correct size and type of jaw face for the specimen. Finally, verify the alignment of the load string and specimen.

What to do if the jaw faces do not retract from the specimen in my Instron Power Tool?

  If the jaw faces on your Instron Power Tool do not retract from the specimen, it might be because the grips are still pressurized. Toggle the foot switch to remove air pressure on the grips. The jaw face might also be bound to the specimen; lightly tap the jaw face to release the bond. Also refer to 'Jaw faces sticking and jaw holder not retracting' on page 57. The grip may also require lubrication.

  Specimen slippage during loading can occur for several reasons. The jaw faces may be the wrong size or type for the specimen; ensure you install the appropriate jaw faces. Insufficient gripping area can also cause slippage; install the specimen for complete engagement with the jaw faces. Insufficient gripping force may be the issue; verify the air supply pressure and adjust if necessary. Finally, worn jaw faces can lead to slippage, so replace them with new ones.
