NOTE: You will need a 1 inch or 25 mm boring bar holder  to install the Work Probe  onto the turret. The probe kit does not include the tool holder. Refer to theHaasParts.com to purchase the correct tool holder.
Install the boring bar holder  onto desired turret station.
Move the X axis into the position when the tool holder centerline is aligned with the spindle centerline.
NOTE: This position is stored in the settings 319, 320, 321 under the User Positions tab. These settings are set from the factory. If you have a BOT or the BMT tool holder use setting 320. If you use a VDI toolholder use the setting 319.
Attach the probe  to the arbor  using four setscrews with the flat tip  and two setscrews with the tapered tip 
IMPORTANT: Install the setscrews with the flat tip  into the four holes that are closer to the probe. Install the setscrews with the tapered tip  into the two other holes.
Attach the stylus  to the probe .
Install the probe assembly onto the tool holder with the flat face  on the arbor facing the setscrew  and the rear shoulder of the arbor flat against the front face of the tool holder. Torque the setscrew .
Install the coaxial indicator  onto the chuck.
Keep the tool holder centerline inline with the spindle centerline and sweep the probe stylus tip with the indicator. Keep the tapered setscrews  snug and adjust the flat setscrews  until the stylus tip is inline with the spindle centerline NTE 0.0005" (0.0127mm). Make sure all of the setscrews are tight when the alignment is done.
