45.3 Earlier damage to the mortar hose
NOTE!
If, in the event of a machine fault caused by
blockages, the pressure in the mortar hose exceeds
40 bar, even only temporarily, replacement of the
mortar hose is recommended as there might be
damage in the hose that is not externally visible.

DANGER!
Danger from discharged material!
Never loosen the hose couplings as long as the
pressure head is reduced! Material to be conveyed
can be discharged under pressure and cause injuries
particularly to the eyes.
Persons commissioned with the cleaning of clogged
hoses have to wear personal protective equipment
(protective goggles, gloves) for safety reasons, and to
position themselves in such a way that they cannot be
hit by discharged material. Other persons have to
clear the area.
46.1 Let the pump motor run backwards
Fig. 78: Reverse operation
NOTE!
During reverse operation of the pump, water for the
mixing section is not disconnected.
The air tap must not be opened for the reverse
operation.
1. Remove the water hose (1) from the mixing tube and put it in a
bucket or pan.
2. Turn the selector switch (2) anticlockwise to position “REV”
(machine runs backwards).
3. Let the machine run backwards briefly till the pressure at the
mortar pressure gauge has dropped to "0 bar".
4. Turn the selector switch (1) to “0” position (middle position).
5. Connect the water hose (1) to the mixing tube.
6. Turn the selector switch (2) clockwise to position "FWD".
7. The RITMO L Eco starts again as soon as the air tap at the
spraying gun is re-opened.
