DANGER

If you are required to put your hand inside 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.

CLEANINGTHE 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 on page 26, ensure that there is no blockage in the hose and line or in the shuttle tube (using the Shuttle Tube Inspection Procedure, page 26-27). 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.
