the hose fitting portion of the valve to the left in order to face it toward the air hose.
Use caution not to over tighten the valve or hold the tool at an angle that may cause
the threaded portion of the valve to accidentally crack or shear off.
7) Insert the quick disconnect fitting into the
cutting head hole nearest you, where the
original flow control valve had been mounted.
Tighten this fitting with the 5/16” nut driver as
well.
8) Insert the clear air hose into the new
flow control valve, and the black hose
into the quick disconnect fitting. Make
sure that each hose is fully inserted
by tugging on it after pushing inward
completely.
9) Re-connect the main air hose to the machine. Make a test cut and check for
acceptable amount of over-cut. Open the adjusting knob (CCW), to lengthen the
Start of Cut, and close the valve (CW), to reduce the Start of Cut or slow down the
rate of blade plunge. Be sure to tighten the knurled silver lock ring once you have
achieved the desired plunge speed / over-cut.
See the Calibration section for more information on flow-control valve adjustment.
