How to use a foot pump?

The foot pump is to change the inflation force point of the pump from hand pressure to foot pressure. This kind of pump also has a barometer, which has the same effect as the vertical pump. In terms of design, some use a single cylinder, and some use a cylinder. In fact, the principle is the same, but the charging efficiency is different.

How to use this pump is:

1. The head of the trachea clamp needs to be inserted into the inflating interface.

2. Step on the air pressure plate to start injecting air pressure.

3. Observe whether the barometer has reached the air pressure you expect.
