DANGER!
Excess pressure on the machine!
While opening the machine components, these can
jump out uncontrollably and injure the operator.
– Open the mortar hoses only when the pressure
has fallen to "0 bar".
Fig. 70: Reverse run
Let the pump motor run in the reverse direction for a short
duration:
1. Set main reverse switch (1) to position "I".
2. Press the green pushbutton (2) Control voltage "ON".
3. Press blue key (3) Reverse running direction of rotation (water
supply is stopped automatically), till pressure in mortar pressure
manometer drops to "0 bar".
4. Cover the pressure flange to mortar hose area with film.
28.5 Releasing residual pressure
Fig. 71: Loosening nuts.
1. Loosen the nuts of the tie rod (4) slightly so that possibly existing
residual pressure can escape fully.
2. Detach hose coupling (5) and clean mortar hoses immediately.
3. To remove the remaining material from the mortar hoses,
introduce a flushing hose in the mortar hose and flush the
material out (PFT Flushing hose, Art. No. 00113856).
4. Re-tighten nuts of the tie rod (4) finally.
29 Measures during power failure
