visible, check the inside of the adjustment knob. If it is inside the adjustment knob, use a 1/16 in. hex wrench to
loosen the screw in the adjustment valve so the brass collar can be removed.
3. Rotate the shaft fully clockwise to close the flow adjust valve.
4. Place the brass collar back on the shaft and ensure it is against the vernier barrel. Use a 1/16 in. hex wrench
inserted into the hole (Figure H.3) and tighten the brass collar onto the shaft, ensuring it stays tightly against the
vernier barrel.
5. Line up the adjustment knob with zero at 12 o’clock, and insert over the brass collar and to the last line of the valve
body. Using the 1/16 in. hex wrench, insert into the hole as shown in Figure H.4 and tighten.
6. Turn the valve slowly counter-clockwise to open. Each full rotation should equal one line on the barrel. Rotate the
knob to the value recorded on the calibration sticker. If there is no value on the calibration sticker, the default value is
10.
