ADJUSTMENTS
SHUTOFF VALVE ADJUSTMENT
PROCEDURE
Adjustment of Shutoff Valve (for 6WT or 6WRT)
Adjustment to the Shutoff Valve system is preset at the
factory. Do not adjust any part of the Valve unless, after
prolonged use of the Tool, the Tool shuts off prematurely
or the Tool fails to shut off. Only if either of these
conditions exists are you to adjust the Valve. Adjust the
Valve according to the procedures below.
1. Turn the Regulator Adjustment Screw until the top of the
Screw is approximately two threads below the face of the
Regulator Body. Set the Bleed Adjustment Screw
approximately four threads below the face of the
Regulator Body. See Dwg. TPD1071.

2. Cycle the tool on a test joint to test for shutoff.
See Dwg. TPD1074.

Test Joint – 55 psig
3. If the tool fails to shut off:
a. Turn the Bleed Adjustment Screw clockwise a
little at a time, until consistent shutoff occurs. If
no shutoff occurs, reset the Bleed Adjustment
Screw four turns under flush. See Dwg. TPD1072.
Set the Regulator Adjustment Screw 1/4 turn deeper
and repeat steps 2 and 3. See Dwg. TPD1073.
b. If tool shutoff occurs, turn the Bleed Adjustment
Screw counterclockwise until the tool stalls on a
test joint. When the tool stalls, rotate the Bleed
Adjustment Screw clockwise, a little at a time,
until consistent shutoff occurs. See Dwg. TPD1072.

5. If the tool fails to shut off:
a. Turn the Regulator Adjustment Screw clockwise,
a little at a time, until consistent shutoff occurs.
See Dwg. TPD1073.
b. If tool shutoff occurs, turn the Regulator
Adjustment Screw counterclockwise until the tool
stalls on a test joint. When the tool stalls, rotate
the Regulator Adjustment Screw clockwise 1/8 of
turn at a time until consistent shutoff occurs. This
adjustment provides maximum torque output at
shutoff.
