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 temperature of
below +5° C.
• Allow the motor to cool down. If necessary,
remedy the cause of the overheating.
• Have a service center replace the non-return
valve.
• Check the seals and have any damaged seals
replaced by a service center.
• Tighten the screw by hand. Check the seal on the
screw and replace if necessary.
• Check the compressed air hose and tools and
replace if necessary.
• Check the quick-lock coupling and replace if
necessary.
• Increase the set pressure with the pressure
regulator.
