HOW TO USE YOUR ACCU-GAGE:
Do not use your ACCU-GAGE to test tyres inflated to a higher pressure than the maximum pressure rating of your gauge.
To measure tyre pressure, remove the tyre Presta valve cap and loosen the valve head, rotate the wheel so that the tyre valve is at the top (12 o'clock) of the wheel.
If dirty, clean the Presta valve stem.
Release a little air from the tyre Presta valve to clear any contamination or tubeless tyre sealant.
Push the ACCU-GAGE onto the tyre Presta valve, making sure to push the gauge straight on to the valve stem.
The current tyre pressure will be shown on the dial.
If you remove the gauge from the tyre Presta valve, the current tyre pressure reading will remain until the bleed button is pressed.
To reduce the tyre pressure, hold the gauge on the tyre Presta valve and press the bleed button. When you release the bleed button the new tyre pressure reading will show on the dial.
Once preferred tyre pressure is achieved, remove the gauge, re-tighten the tyre Presta valve head and replace the Presta valve cap.
Press the bleed button to release the reading and return the gauge to zero.
TAKE CARE OF YOUR ACCU-GAGE:
ACCU-GAGE gauges have given decades of reliable tyre pressure readings.
Whilst ACCU-GAGE gauges are known for rugged construction, they are not indestructible. Look after it like you would a smart phone.
When not in use, ACCU-GAGE bicycle pressure gauges should be kept in a clean and dry place, and must not be dropped.
Care should be taken to avoid scratching the gauge's clear face.
For peace of mind, all gauges purchased from www.accu-gagecycling.com come with the optional rubber protection case pre-installed.
Ingress of tubeless tyre sealant into a bicycle tyre pressure gauge (including ACCU-GAGE) will damage its internal mechanisms, care should be taken to clear the tyre valve of sealant before attaching a bicycle tyre pressure gauge.
