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. 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.
During routine maintenance or removing material
blockage, 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,
follow described lock out-tag out procedures. 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 make
sure the accumulator
circuit pressure reads
zero prior to performing any maintenance on the pump.
