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

below 0° C.
Let the motor cool down, if necessary, eliminate
the cause of overheating.
Replace the non-return valve.
Replace the seals, have defective seals
replaced at a specialist workshop.
Tighten the screw by hand. Check the seal on
the screw and replace if necessary.
Check compressed air hose and tools, replace
if necessary.
Check quick coupling, replace if necessary.
Turn up the pressure regulator further.
