In the case of disturbances of the NTP proceed as follows:
Disturbance Possible cause Corrective action
No start Silencer polluted Clean silencer.

supply Check if there is enough pressure at the NTP.
Check valve. A 3/2-way valve is recommended, so
that the supply line to the NTP is vented.
Cover loose A leaky cover leads to standstill of the NTP.
Tighten screws.
Wire cross-sections Observe recommended cross-sections (see Ch.
Technical data, from page 7 on).
Line too long be-
