Clearing hose blockages
WARNING!
According to the accident prevention regulations of the Builders’ Guild, for
safety reasons, all personnel assigned with clearing hose blockages should
wear safety goggles and position themselves in such a way as to avoid
injury by discharged mortar. No other persons should be present in the
danger zone.
Run the machine in reverse.
In doing so, turn the selection switch (1) to the left and hold it until the
pressure at the mortar pressure gauge has fallen to 0 bar.
Loosen the two nuts on the pressure flange lightly so that entire residual
pressure is released.
Undo the hose coupling and clean the hose.
Measures to be taken in the event of a power failure
If duration or cause of the power failure are not known, it is recommended to thoroughly clean the
machine, hoses and spray gun. Otherwise hardened material can cause considerable damage to
the machine. See “Measures to be taken when work is finished or interrupted” for the further
procedure.
WARNING!
Make sure all hoses are depressurised before opening the couplings
(observe the mortar pressure gauge display).
Measures to be taken in the event of a water supply failure
Use suction inlet (item no.: 00 00 69 06) and high pressure pump to supply the machine with clean
water from a container.
