Tire Gauge
Instructions
WARNING: A failure resulting in injury or damage may be caused by pressure beyond the top of scale,
excessive vibration or pressure pulsation, excessive instrument temperature, corrosion of the pressure
containing parts or other misuse. Refer to ASME B40.100-2005.
Do Not Use on Oxygen Service.
Use: Push tire stem into the tire gauge valve stem and hold for 2 seconds. Remove the tire gauge from
the tire valve stem. Check the gauge pointer for the tire pressure reading. Push-in the pressure relief
button on the gauge stem to bleed the tire pressure from the tire gauge so the pointer returns to zero.
Repeat these steps more than once to ensure an accurate tire pressure reading.
PGV
If the pointer is o zero when no pressure is applied to the gauge, remove the black cover by hand and
remove the snap-in lens with a small screwdriver. Re-zero the pointer by slightly rotating the re-zero
screw located on the gauge dial in a clockwise or counterclockwise direction. Push the lens back on to
the gauge case and place the protective cover back on to the gauge housing by hand.
