PRECAUTIONS
1. Sensors will work with all valve stems – However, rubber 90° valve stems do not last as long as
metal and depending on the age and quality of your rubber 90° valve stem you need to make sure
they are in good shape. We do recommend the use of metal valve stems for better durability. Please
verify clearance when used with a 90 degree valve stem (Softail, etc.) to clear any and all calipers
or other components before use.
2. Make sure the LCD Receiver/Monitor can receive signals from all tire pressure sensors.
3. TireGard™ WTPMS has a unique anti-theft device to prevent the sensors from being stolen.
4. Please confirm that all sensors are fitted tightly. If necessary, spread detergent water on the valve
stem to check for any air leakage. DO NOT OVER TIGHTEN SENSORS.
5. If tire pressure is low or dropping quickly, stop the motorcycle immediately and determine the
problem.
6. The monitor will automatically make a connection with the sensors. It is normal that tire pressure
figures might not be updated immediately due to changes of tire pressure.
7. TireGard™ WTPMS is designed to avoid interfering or being interfered with by other signals.
8. Many environmental factors can cause tire temperature to rise or fall. For example, hot weather or a
warm tire will result in rising tire pressures.
9. The LCD Receiver/Monitor is NOT waterproof. If the LCD Receiver/Monitor accidentally gets wet,
do not ‘power on’ the system until it is completely dried.
10. If you have any questions concerning your TPMS unit, please contact your Dealer or email
[email protected].

2. Installation of the External Sensors (See page 12 for Installation of the Internal Sensors)
Each sensor is designed specifically for the tire location as denoted by its number; you have to
make sure the sensors are installed in their specified positions. See diagrams starting on page 4.
When inserting the batteries into the sensors, do not mix up the Front (1) and Rear (2) sensor caps.
Each sensor is marked on its cap and within its body indicating its position on the motorcycle.
Insert Batteries in External Sensors
Battery Installation for Tire Pressure External Sensor:
A. Remove sensor cap by rotating counter-clockwise.
B. When inserting lithium battery make sure battery polarity is correct.
Immediately the LCD Receiver/Monitor will receive signals from the corresponding sensors and
report the pressure value on the screen. At first, you will find the value shows “00.0”. It is because
sensors have not been mounted yet.
Note: After removing the battery, you will need to let the system reset. Please allow it to sit for 10
seconds before inserting the battery again.

10
A. Install sensor cap by rotating clockwise (Tighten completely by hand. Do not use a tool).
Please ensure the sensors are in the correct (1, 2, 3 or 4) position. Do not mix up sensor caps. Both
sensor cap and sensor body have reference marks indicating position.
(1, 2, 3 or 4) for example
Please verify clearance when used with a 90 degree valve stem (Softail, etc.) to clear any and all
calipers or other components before use.

11
Anti –Theft Ring for External Sensors: (installation is optional)
Anti –Theft Ring is designed to prevent the possibility of sensors being easily stolen.
A. Place theAnti-Theft Ring onto the valve stem.
B. Install sensor onto valve stem. Do not over tighten the sensor as it may become damaged.
C. Adjust the Anti-Theft Ring position to seat it with the sensor firmly in place.
D. Insert the hex socket screw into the Anti-Theft Ring.
(Do not exert excessive pressure as damage to the valve may occur.)
E. When all of the tire pressure sensors are installed, check for air leaks using detergent water.
(Spread detergent water on the valve stem and watch for bubbles.) If the tire pressure sensors
and tire valves are properly fitted, no air will be leaking from the system.
