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. To inate or deate the tire, you must
remove the cap sensor.
