3.Using a 1/4" allen wrench, adjust the small hex nut within the larger hex jam nut.
4.Tighten 3/4" jam nut.
5.Check the pressure as described earlier (see Pitch Pressure Check section).
6.If pressure requires further adjustment, repeat steps 2 through 4 until pressure check reads 1850 ± 50 PSI.
7.Record pressure on Machine Information and Maintenance Log.
8.Return machine engine rpm to idle.
9.Turn off machine and remove gauge.
