Machine Pre-Use Checks
Pre-use checks are a daily routine to confirm the machine is safe before work starts. Learn the check categories: fluids (engine oil, coolant, hydraulic oil, fuel, AdBlue where fitted), tyres and wheels (condition, pressure, damage, correct inflation), structural items (boom, pins, hoses, welds, cracks), safety devices (seat belt, horn, lights, beacons, reversing alarm, overload indicator, load moment system), and housekeeping (steps, handrails, mirrors, cab cleanliness).
Understand the purpose: to detect defects before they cause harm, and to record them. Defects must be reported and, if safety-critical, the machine must be taken out of service until rectified. A pre-use check is not a substitute for planned maintenance.
Traps:
- Confusing a pre-use check (operator, daily) with a thorough examination (competent person, periodic).
- Thinking a defect can be 'worked around' if it is not safety-critical - record it regardless.
- Forgetting to check the load chart and capacity plate are present and legible.
- Assuming tyre pressure is unimportant - incorrect pressure affects stability and handling.
- Overlooking the seat belt and its anchorage.
Rule of thumb: If a defect affects lifting, braking, steering, stability or warning devices, the machine does not work until it is fixed. When in doubt, park it and report it.
Worked example: During the walk-round you find a hydraulic hose with a damp patch and a small bulge. This is a potential burst risk - tag the machine out of service, report it, and do not operate until repaired and inspected.
