How to clean the air button discharge for HiPreMa digital tire gauges.
If the HiPreMa 4 digital pressure gauge is leaking air, it is possible that:
1 - The outer air hose broke. If so, contact us to receive one to replace or buy directly on our ecommerce.
2 - It is possible that some dirt (small asphalt chips) got into the air button discharge. In that case you can clean it.
To avoid dirt inside the air hose, it is recommended to use caps on the rim valves.
This video shows the procedure for cleaning the air button discharge of the HiPreMa 4/5 digital tire pressure gauge.
