CLEANING THE PUMP AND DELIVERY SYSTEM
Cleaning the pump is a very important operation as it
determines how the machine will pump the next time it is
used.
At the end of every pour, or because of long delays during a
pour, the pump and delivery system must be thoroughly
cleaned by removing all concrete material.
1. Following the Clearing Concrete Blockage operating
procedure, ensure that there is no blockage in the hose
and line or in the shuttle tube (using the Shuttle Tube
Inspection Procedure). If a blockage exists, clear it.
2. Pump concrete until the opening of the concrete cylinder
intake in the hopper is visible.
3. Stop the pump.
4. Carefully disconnect the first hose joint at the shuttle
tube discharge elbow.
You will be required to put your hand in the concrete
cylinders or near the shuttle tube. You are at
EXTREME RISK of injury or AMPUTATION if the
engine is running or if pressure is in the hydraulic
system.
Prior to performing any maintenance on the pump, stop
the engine by turning off the ignition switch and remove
the starter key. Place a “DO NOT OPERATE” tag
over the switch and disconnect the battery. The
pressure reading on the accumulator pressure gauge
MUST read ZERO. ALWAYS relieve the accumulator
circuit to zero pressure
prior to performing any
maintenance on the
pump.
