The air supply pressure is low.
Check the compressor and the configuration of the air line. Adjust the air pressure.
Air leaks in connecting elements.
Check the connection elements and the tightening of the screws.
The air pipes or ancillary equipment is clogged with mud.
Check and clean the air line.
