Remedy
Check cable, mains plug, fuse and socket.
Avoid extension cables that are too long. Use
extension cables with sufficient conductor

Let the motor cool down, if necessary, eliminate
the cause of overheating.
Replace the non-return valve.
Check the seals and have any damaged seals
replaced by a service centre.
Tighten the screw by hand. Check the seal on
the screw and replace if necessary.
Check compressed air hose and tools, replace
