for the C30HDZ Concrete Pump. The function of each
component is described below:
1. Discharge Cone – Connect 3" elbow to this discharge
port, then connect 3" x 2" reducer to elbow.
2. Discharge Cone Safety Latch – When towing of the pump
is required,
ALWAYS
secure the discharge cone to latch
located on the manifold.
3. Rear Running Lights – ALWAYS check and make sure
both the right and left running lights are functioning correctly
before towing the pump.
