plate or decal on or near the bottle or air filler valve. If
the instruction plate is missing or not readable, the
information may be found in the General Information
and Servicing section of the applicable MIM.
Pressure should be added to air storage bottles
slowly in order not to build up heat from rapid transfer.
You should take care to ensure that air storage bottles
are not overinflated.
