Pre-Operation Inspection
What the exam tests
Pre-Operation Inspection tests the walk-around and functional checks before the first shift or after a change of machine. The exam expects a sequence: paperwork, visual inspection, fluid checks, safety devices, then start-up and control tests.
Core rules
- Confirm the machine is the correct type, has a valid inspection record and is on a suitable surface. Check for leaks under the machine and for damaged hoses, pins, tracks, tyres and guards.
- Check engine oil, coolant, hydraulic oil, fuel and grease points at the manufacturer's intervals. Do not open a hot pressurised system.
- Inspect ROPS/FOPS, seat belt, seat, mirrors, cameras, horn, lights, reverse alarm, fire extinguisher and first-aid kit.
- For lifting equipment, inspect wire rope, hooks, safety latches, sheaves, outriggers and the load chart. For earthmoving equipment, check bucket teeth, cutting edges and quick-coupler locking pins.
- Start the engine and test brakes, steering, hydraulic functions, alarms and controls at low speed in a clear area.
Worked example
A pre-start walk-around finds a hydraulic hose with a swollen bulge near the crimp. The operator must reject the machine and report it. A bulge means the hose reinforcement is damaged and it can burst under pressure. Tightening the fitting or wrapping the hose is not acceptable because the hose is already weakened.
Traps
Do not inspect only after a fault appears. Do not start the engine before the walk-around. Do not ignore a small leak or a missing guard. Do not sign a checklist without performing each item.
Key points
- Walk around before every first shift.
- Reject swollen, cracked or leaking hoses.
- Test brakes and steering in a clear area.
- Record defects before operating.
