    2121Possible Solution:
    22         1. The finger cable pretension is not adjusted properly.  [[FingerCablePretensioning| Set the finger cable pretension properly.]]
     22        1. The finger cable pretension is not adjusted properly.  [[Hand/280/FingerCablePretensioning| Set the finger cable pretension properly.]]
    2323        1. The strain gage balancing potentiometer needs to be [[StrainGageMaintenance| readjusted]].
    2424        1. Verify the cable is riding properly on the idler pulley, as shown in Figure 25.
     
    4242        1. Verify that the strain gage value SG is less than HSG (High Strain Gage Limit; alias is MSG).
    4343        1. If the strain gages are not installed set HSG to 256 for the BH8-262.
    44         1. The finger cable pretension is too high.  [[FingerCablePretensioning| Set the finger cable pretension properly.]]
     44        1. The finger cable pretension is too high.  [[Hand/280/FingerCablePretensioning| Set the finger cable pretension properly.]]
    4545        1. Set the open velocity greater than or equal to 40 and then initialize the finger. 
    46         1. [[FirmwareUpdate| Reload firmware.]]
     46        1. [[Hand/280/FirmwareUpdate| Reload firmware.]]
    4747        1. If the problem persists, contact Barrett Technology.
    4848
     
    9090        1. Adjust close target CT so that it is either at or just beyond the actual palm surface.
    9191        1. Verify that the outer link has not broken away prematurely.
    92         1. Verify proper finger angles when the fingers are removed and replaced during lubrication maintenance.  An error here can cause the outer finger link to reach its joint stop prematurely, even without breakaway, before either CT or the inner finger-link joint limit is reached. Verify finger angle is correct by [[LubricationAndFingerReplacement| disconnecting and reattaching fingers.]]  Readjust if necessary.
     92        1. Verify proper finger angles when the fingers are removed and replaced during lubrication maintenance.  An error here can cause the outer finger link to reach its joint stop prematurely, even without breakaway, before either CT or the inner finger-link joint limit is reached. Verify finger angle is correct by [[Hand/280/LubricationAndFingerReplacement| disconnecting and reattaching fingers.]]  Readjust if necessary.
    9393        1. Verify there are no objects or other fingers blocking the finger from closing completely.
    9494        1. Verify the MSG (Maximum Strain Gage) property is greater than the strain gage value (SG). If the strain gages are not installed, set MSG to 256.

    9999Possible Solution:
    100         1. [[LubricationAndFingerReplacement| Lubricate the spread motor gears.]]
     100        1. [[Hand/280/LubricationAndFingerReplacement| Lubricate the spread motor gears.]]
    101101        1. If the palm screws have been reinstalled, verify all screws are tightened with the same amount of torque.  Excessive torque may cause spread friction.
    102102        1. If the problem persists, contact Barrett Technology.
     
    116116
    117117Possible Solution:
    118         1. The pretension in the cable is too low.  [[FingerCablePretensioning| Set the finger cable pretension properly.]]  If the problem persists, contact Barrett Technology.
     118        1. The pretension in the cable is too low.  [[Hand/280/FingerCablePretensioning| Set the finger cable pretension properly.]]  If the problem persists, contact Barrett Technology.
    119119        1. The finger cable is broken.  Verify this by removing the Shroud Cover, see Figure 23, and inspecting the cable.  The cable should be intact and not broken.  If the cable is broken, contact Barrett Technology.
