Clean the drain button of the digital pressure gauge.

If the HiPreMa 4 digital pressure gauge is leaking air, it is possible that:

  1. The outer tarpaulin air hose broke. If so, contact us to receive one for replacement.
  2. It is possible that some dirt ( small asphalt chips ) got into the air exhaust button. In that case you can unscrew the button and 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 exhaust button of the HiPreMa 4 digital pressure gauge.
