Pre-Operational Inspection
Pre-Operational Inspection
This domain tests the walk-around and function checks required before each shift on a telehandler. Under ANSI/ITSDF B56.6 and the operator manual, this is a remove-from-service decision: the exam expects you to find defects that make the machine unsafe, not just list parts.
What to inspect
- Documentation and labels: operator manual, load chart, capacity plate, decals, and inspection records. The load chart must match the installed attachment.
- Fluids and leaks: engine oil, hydraulic oil, coolant, fuel, and battery condition; look for damp fittings, drips, and damaged hoses.
- Structure and lifting components: boom sections, pins, wear pads, chains if equipped, cylinders, hoses, quick-attach, carriage, forks, and fork locks.
- Tires and wheels: pressure, cuts, bulges, exposed cords, loose lug nuts, and wheel damage.
- Safety devices: ROPS/FOPS, seat belt, horn, backup alarm, lights, beacon, mirrors, level indicator, service brake, parking brake, and emergency lowering.
Function test
Start the machine and check gauges and warning lights. With controls in neutral, test boom lift/lower, extend/retract, tilt, frame leveling, steering modes, brakes, and parking brake. Any defect that affects safe operation means tag out, report, and do not operate.
Worked example
An operator finds a lift-circuit hose with a chafed cover and a damp spot at the fitting. Reasoning: a damp fitting indicates a leak, and a chafed pressure hose can burst under load. This is not cosmetic; remove the machine from service until repaired.
Traps
- Doing a visual check only and skipping the function test.
- Ignoring tire pressure or sidewall damage.
- Operating with a missing or mismatched load chart.
- Assuming the backup alarm and horn work without testing them.
