Solution
1. Check the supply voltage, the pow-
er plug and the socket-outlet.
2. Make sure that the extension cable
is not too long. Use an extension
cable with large enough wires.
3. Never operate with an outside tem-
perature of below +5° C.
4. Allow the motor to cool down. If
necessary, remedy the cause of the
overheating.
1. Have a service center replace the
non-return valve.
2. Check the seals and have any da-
maged seals replaced by a service
center.
3. Tighten the screw by hand. Check
the seal on the screw and replace if
necessary.
1. Check the compressed air hose
and tools and replace if necessary.
2. Check the quick-lock coupling and
replace if necessary.
3. Increase the set pressure with the
pressure regulator.
