Simply press the chuck onto the valve, the pressure reading is held in the gauge, note the pressure, then release the air with the button as you require. Bleed button can be used to release air and view the actual pressure drop for precise settings The large clear gauge face is 50mm/2'' diameter with a white background, black digits and needle, viewed through a clear window. The rugged steel body is protected with a rubber boot. The flexible hose and chuck allows access to recessed valves in deep wheels or wheels with difficult access.

For use on Schrader valves fitted as standard by all car and motorcycle manufacturers around the world. Gauge usage Notes: For accuracy and base figure, check pressure when tyres are cold. Pressure increases with heat, tyre pressures can increase during normal use Tyres can lose one pound per month under normal conditions. Correct tyre pressure improves fuel efficiency, handling, braking and tyre durability To avoid the possibility of eye injury, eye protection must be worn when using this gauge Do not exceed maximum pressure on gauge Dropping or severe jarring may impair accuracy of gauge
