1. DIAGRAM OF AIR SYSTEM IN STANDBY CONDITION. Trigger released, compressed air attached, collet unclamped, cutter fully retracted, air motor stopped.
2. DIAGRAM OF AIR SYSTEM AT FULL COLLET STROKE AND START OF CUTTER FEED. Trigger depressed, pilot and unclamp check valves shift, air motor starts, collet first clamps fully, then cutter starts feeding and continues to feed until pre-set depth has been reached (See Figure 3).
3. DIAGRAM OF AIR SYSTEM AT PRE-SET CUTTER DEPTH AND START OF RETRACT. Trigger depressed, air motor running collet clamped, cutter continues feeding until depth control adjustment covers retract and dwell port, shifting retract and dwell valve, initiating rapid cutter retract.
4. DIAGRAM OF AIR SYSTEM AT COMPLETION OF RETRACT STROKE. Trigger depressed, collet clamped, air motor running. NOTE: Release trigger causes shifting of pilot, clamp- unclamp and retract valves, collet unclamps and air motor stops (See Figure 1).
