11. Possible causes of failure
Problem
Cause
Solution
The compressor
does not start.
1. No supply voltage.
2. Insuffi cient supply voltage.
3. Outside temperature is too low.
4. Motor is overheated.
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.
The compressor
starts but there is no
pressure.
1. The non-return valve leaks.
2. The seals are damaged.
3. The drain plug for condensation
water (9) leaks.
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.
The compressor
starts, pressure is
shown on the pres-
sure gauge, but the
tools do not start.
1. The hose connections have a leak.
2. A quick-lock coupling has a leak.
3. Insuffi cient pressure set on the pres-
sure regulator (3).
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.
