Carry out driver maintenance.


Concrete agitator truck is safely parked, prepared for maintenance and shut down as per manufacturer manual and organisational requirements.


Inspection and fault finding are conducted according to manufacturer specifications and recorded according to organisational procedures.


Defective parts are removed and replaced safely and effectively according to manufacturer instructions.


Regular programmed maintenance tasks are carried out according to manufacturer and organisational requirements.


Clean up.


Work area is cleared and materials disposed of, reused or recycled according to project environmental management plan.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

This unit of competency could be assessed by observation in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

A person should demonstrate the ability to:

conduct concrete agitator truck operations, over not less than three shifts and two different sites, including the safe and effective:

positioning of the vehicle at the load point

loading and transporting of concrete

discharging of concrete at work site to specification

discharging directly to site

discharging to wheelbarrow and hopper

applying emergency procedures
