SENSOR INSTALLATION - FLOW-THRU SENSOR
Note: These sensors can only be used on metal valve stems.
1. Screw the hex nut onto the valve stem threads until it bottoms out. The hex nut is
not required, but is provided as a theft deterrent.
2. Screw the correctly marked sensor onto the valve stem for that tire position. Tighten
the sensor until the air stops leaking and the sensor bottoms-out on the valve stem.
Then give it a quarter turn more to seat it. Do Not Over Tighten!
3. Use your ngers to screw the hex nut up to the bottom of the sensor. Using the
provided wrench, tighten the hex nut against the bottom of the sensor. This will
prevent the sensor from being removed. Keep the wrench in a safe place for future
use.
4. You can now inate or deate the tire through the 507FT sensor without removing it.
