How to prepare for a CPCS category Theory Test
Learn the operator's safe decision sequence, connect it to the current category learning outcomes and practise explaining why the manufacturer, task and site controls apply.
Core concepts
Concept 1
Checks follow the manufacturer sequence and include machine condition, access, leaks, attachments, tyres or tracks and safety devices.
Exam cue: Move from walk-around to cab and controlled function test.
Concept 2
Functional checks are carried out in a safe area before productive use and include alarms, brakes, steering, interlocks and indicators as applicable.
Exam cue: Know which checks require isolation or specialist attention.
Concept 3
A check is evidence gathering, not permission to adjust or repair beyond authority.
