When used to install double action fasteners, the shift valve of the Model 200 H.I.T. must be adjusted to insure
the proper installation of various fasteners. Two methods of checking the shift valve setting are available:
Method #1: Shift Setting Kit No. 107569 employs a Skidmore-Wilhelm Tension Tester to check the spindle
Load at shift, in pounds.
Method #2: Shift Setting Kit No. 101300 employs a hydraulic pressure gauge to check the hydraulic pressure
at shift, in pounds per square inch (psi).
The table below shows the ‘Spindle load at Shift” and “Hydraulic Pressure at Shift” for various fasteners.
