Emergency Procedures
Electrical power loss
If there is an electrical malfunction, the E-stop circuit
dump valves will open, disabling the hydraulic circuit.
To continue use, remove the cable connector from the
E-Stop harness and replace it with the Emergency
Power Cable Plug. This will restore power to the dump
valves and allow the system to build hydraulic pressure.
Hydraulic functions can now be controlled by the over-
ride handles.

If you cannot correct the electrical power loss problem,
try activating the dump valves by pushing the two over-
ride buttons on the E-stop while another person acti-
vates the concrete pump forward/reverse handle, on
the S1/S2 Control Block. Activating the three valves will
close the dump valves allowing the accumulator to shift
the concrete valve and the pump to be cleaned out.

For information on where to look and what to do if you
lose electricity on the unit, contact the Schwing Service
Center at (888) 292-0262.
Loss of Radio/Cable remote
The Radio/Cable Remote is considered the primary
control source for the stationary pump. If you lose the
remote control for any reason, you can still operate the
stationary pump from the rear operator panel.
If your Radio Remote stops functioning and the battery
LED is o, the battery is probably dead. Remove the
battery from the Radio Remote, and replace it with a
fully charged battery. The dead battery should then be
placed in the charger.
