Remedy
Check the supply voltage, the power plug
and the socket-outlet.
Make sure that the extension cable is not
too long. Use an extension cable with
large enough wires.
Never operate with an outside tempera-
ture of below +5° C.
Allow the motor to cool down. If neces-
sary, remedy the cause of the overheat-
ing.
Have a service center replace the non-re-
turn valve.
Check the seals and have any damaged
seals replaced by a service center.
Check the compressed air hose and tools
and replace if necessary.
Check the quick-lock coupling and re-
place if necessary.
