Pre-start checks are the first piece of competence an examiner sees. On CPCS or NPORS test day they’re not looking for a scripted recital; they’re watching for a calm, methodical routine that proves you understand the machine, the environment and when to stop. The check is your chance to show that you can keep yourself, the banksman and the rest of the yard out of harm’s way and that you won’t operate with an unfit machine. Done well, it sets the tone for the rest of the practical.
TL;DR
/>
– Arrive early, read the operator’s manual plate, and explain what you’re checking as you go.
– Start outside-in: environment, walkaround, fluids, structure and attachments, then cab and safety devices.
– Test what’s safe to test, record checks properly, and report defects without bluffing.
– If anything is unsafe, isolate and escalate; doing the right thing is viewed positively.
What examiners actually expect from pre-start checks
/> Examiners expect a logical, repeatable order that follows the manufacturer’s instructions and basic site rules. They want to see you scan the work area first, set an exclusion zone if needed, then move around the machine in a consistent direction. You should be able to name what you’re checking and why, not just point and move on.
They expect you to identify anything that would stop the job: leaks, loose pins, cracked hoses, missing pins or locking devices, damaged tyres/tracks, inoperative safety systems, or attachments that are not correctly secured. Safety devices matter: beacons, horn, seat belt, wipers and wash, mirrors or cameras, reversing alarm if fitted, slew lock or slew brake, deadman/enable controls and emergency stops where present.
They also look for how you handle defects. If you find one, you don’t press on. You explain that you would isolate, tag, report and not operate until rectified. That decision-making is part of competence. Lastly, they look for professional basics: stable stance when climbing, three points of contact, ignition off and key out for engine-bay checks, and clean, tidy cabs.
Preparing for pre-start checks: turn it into a routine
/> Preparation is more than reading a checklist once. Spend time with the operator’s manual for the specific machine type you’ll be assessed on and walk it through with an experienced operator or instructor. Learn where key items actually are on common UK models: dipsticks, sight glasses, isolators, slew locks, quick-hitch indicators, boom stops and emergency controls.
Practise your sequence. Outside environment first, then a clockwise or anticlockwise walkaround, then up into the cab. Narrate as you go so it becomes natural to explain and do. If you’ll be tested with an attachment or lifting duty, build that into your routine: check the quick hitch, locking indicators and test, check any lifting accessories and their tags in date, and confirm the rated capacity chart is present and legible.
Prepare your mindset too. Pre-use checks are not a race. Examiners prefer a steady pace with good explanations over speed with gaps. Bring what you need to record checks, be ready to point out where you’d sign defects off, and don’t be shy about asking the assessor to act as a supervisor for a test of a horn or alarm if required by yard rules.
Performing the checks on test day: step-by-step
/> Start with the environment. Look for uneven ground, ice or mud, overhead obstructions, poor segregation, and people drifting into your space. Set a mental or physical exclusion zone, and if you need a banksman later, say so. Make sure the machine is parked safely, attachments on the ground, slew locked or neutralised, and the key with you before you open engine or battery compartments.
Work methodically around the machine. Look at tyres or tracks for damage and tension, check under the machine for drips or puddles, scan hydraulic hoses and cylinders for chafe or leaks, check pins and retainers, see that guards are in place and that decals and data plates are legible. If there’s a quick hitch, check the primary and secondary locks and indicators, the condition of the bucket or forks, and the security of any lifting point. Check fluids to the manufacturer’s method, not guesswork. Only then move into the cab.
In the cab, set your seat and mirrors, test the seat belt, check that windows are clean, and confirm wipers and washers work. With safe clearance and warning others if needed, power up and test beacons, horn, reversing alarm if fitted, cameras, deadman controls and emergency stops where appropriate. Bring the hydraulics to life gently, checking for excessive movement or drift, and confirm slew lock or travel lock engages and releases. If a banksman will be used later, confirm your hand signals and plan safe routes.
Scenario: A training yard in the Midlands has a 360 excavator booked for tests after heavy rain. The excavator is parked on crushed aggregate near a pedestrian route to the welfare cabin. You arrive early, put a couple of cones to widen your exclusion area and ask the assessor to keep foot traffic out while you test the horn and beacon. During your walkaround you spot a wet patch under a track motor area; you wipe it, watch for fresh oil, and find it’s water and grease wash-off rather than an active leak. In the cab you adjust mirrors, test the seat belt and horn, then warn the assessor before testing the slew lock. You gently cycle the hydraulics, checking hoses for movement under pressure, and note a cracked mirror that doesn’t affect visibility; you explain you’d report it and continue if permitted. The routine is steady, you explain each step, and nothing feels rushed.
Pre-start essentials checklist
– Confirm safe area: ground conditions, overheads, segregation and your exclusion zone
– Walkaround for structure, leaks, hoses, pins, guards, tyres/tracks and under-machine drips
– Fluids to manufacturer’s method: hydraulic oil, engine oil, coolant, fuel and washer fluid
– Attachments and quick hitch: locks, indicators, pins, wear and any lifting point condition
– Cab safety items: seat belt, mirrors or cameras, cleanliness, visibility and fire extinguisher if fitted
– Safety devices: beacon, horn, reversing alarm if fitted, emergency stops and deadman controls
– Controls and locks: slew/travel lock, parking brake, gauges, warning lights and documentation presence
# Common mistakes
/>
– Rushing the exterior check and missing simple show-stoppers like missing split pins or a loose bucket latch. Slow down and look with purpose.
– Climbing onto tracks or bodywork with the engine live and the key in. Remove the key and use three points of contact.
– Testing alarms or hydraulics without warning people in the area. Set an exclusion zone and communicate before live tests.
– Bluffing through a defect. If you’re unsure, say what you would do and stop; honesty is safer and scores better than guesswork.
Staying sharp after the test: keeping pre-use checks meaningful
/> Passing the assessment isn’t the end of pre-use checks. On live sites, the daily checkbook and defect reporting process are as important as the checks themselves. Build your routine into every start of shift, and don’t let time pressure erode it. Supervisors should see consistent entries and timely reports, not tick-and-go.
Keep your knowledge current as you move between machines and brands. Controls and safety devices differ, quick hitches vary, and camera systems or alarms won’t all behave the same. If you return to a category after a break, ask for a refresher or toolbox talk and review the manual. Competence drifts when routines are skipped.
Bottom line: on test day, a clean, systematic pre-start is proof that you’re safe to trust with the machine. Make it a habit now, and it will carry you through assessments and live shifts alike.
FAQ
# How long should pre-start checks take in a CPCS or NPORS test?
/> There isn’t a fixed time you must hit, but it shouldn’t look rushed or padded out. Examiners are looking for a steady pace that shows you know what you’re checking and why. If you find something that needs a closer look, take the time to do it properly and explain what you’re doing.
# Do I need to complete paperwork during the assessment?
/> Centres vary. Some will have a sample check sheet to complete, others will ask you to explain what you would record and who you’d report defects to. Be prepared to demonstrate both: how you’d record the check and how you’d escalate a defect.
# What if I find a defect before starting the practical?
/> State clearly that you would not operate and explain the isolate–tag–report steps you’d follow. The assessor may simulate a safe rectification or move you to another machine, but they will credit the decision-making. Avoid trying to “work around” a fault to keep the test moving.
# Are pre-start checks different for telehandlers versus excavators?
/> The principles are the same: environment, structure, fluids, attachments, cab and safety devices. The detail differs: telehandlers bring tyres, forks, mast and load charts into focus, while excavators add slew locks, tracks and quick-hitch checks. Always tailor your routine to the machine and attachment actually in front of you.
# How often should I refresh my understanding of pre-use checks?
/> There’s no single rule that suits every operator, but refreshing before card renewal, when changing machine types, or after time away from the controls is sensible. Many sites also build pre-use checks into refresher or toolbox talks. If you’re unsure, ask your supervisor for a short update or supervised run-through.
