Holding Pressure
Adjustment
PRESSURE GAUGE
GENERAL:
THE HOLDING PRESSURE REFERS TO THE CONTROLLED PRESSURE IN THE TOOL THAT OCCURS
AFTER THE CLAMP HAS BEEN TENSIONED AND THE CONTROL LEVER HAS BEEN POSITIONED TO THE
NEUTRAL POSITION. IN THIS POSITION, THE PRESSURE IN THE TOOL BLEEDS DOWN FROM THE
PULL PRESSURE TO THE HOLDING PRESURE CONTROLLED BY THE HOLD PRESSURE CONTROL
VALVE. THESE PRESSURES ARE READ ON THE PRESSURE GAUGE.
FOR GENERAL USE, THESE TOOLS ARE SET AT 7 - 8 PSI AT THE FACTORY AND THE ADJUSTMENT IS
SEALED.
ONCE SET, PULL UP PRESSURE HAS BEEN ACHIEVED AND VALVE HANDLE HAS BEEN PUT IN
NEUTRAL POSITION, THE PRESSURE SHOULD DROP RAPIDLY AND THEN REACH SET HOLDING
PRESSURE AND STOP THERE.
THE HOLDING PRESSURE IS READ ON THE GAUGE AND IS THE PRESSURE WHICH SHOULD BE
SHOWING WHEN A JUNIOR PREFORMED CLAMP IS TO BE ROLLED OVER AND CUT OFF.
ADJUSTMENT OF HOLDING PRESSURE:
TO ADJUST THE HOLDING PRESSURE, REMOVE THE SEAL, RELEASE THE WHITE LOCKING RING TO
UNLOCK THE KNOB AND TURN THE VALVE CONTROL KNOB CLOCKWISE AS FAR AS POSSIBLE. SET
THE PULL PRESSURE AT 40 PSI OR HIGHER AND OPERATE THE TOOL (CLAMP NOT REQUIRED).
ALLOW THE TOOL TO REACH THE PULL PRESSURE THEN MOVE THE CONTROL VALVE TO NEUTRAL
POSITION. NOW, SLOWLY TURN THE ADJUSTMENT KNOB COUNTERCLOCKWISE AND YOU HEAR THE
AIR EXHAUST AND OBSERVE THE HOLDING PRESSURE DROP. TURN THE KNOB AS NEEDED TO GET
THE PRESSURE TO THE RECOMMENDED SETTING (PAGE 6). PUSH THE WHITE LOCKING RING DOWN
TO LOCK THE KNOB, NOW THE TOOL IS READY TO USE. IF THE VALVE DOES NOT HOLD THE
PRESSURE, THE VALVE IS DEFECTIVE AND SHOULD BE REPLACED. IT IS RECOMMENDED TO CYCLE
THE TOOL A FEW TIMES AND OBSERVE THAT PRESSURES ALWAYS REACH THE LEVEL SELECTED.
TO OPTIMIZE CLAMP CUT-OFF AND CLAMP LOCKING, IT IS RECOMMENDED THAT THE CLAMP HOLD
PRESSURES (SHOWN ON PAGE 6) BE USED FOR DIFFERENT CLAMP WIDTHS.
