Practice Questions: Machine Operations & Pre-Use Checks
While general site safety is universal, a significant portion of your NPORS theory test will focus on the specific machine you are being tested on. The principles of pre-use checks and safe operation are similar, but the details for a 360 Excavator will differ from those for a Telehandler. This section provides sample npors theory test questions and answers to demonstrate the type of machine-specific knowledge you’ll need.
Mastering these details is what separates a competent operator from a novice. It shows you understand your machine inside and out, which is crucial for safety and efficiency on site.
Pre-Start Inspections and Maintenance
Your daily walk-around check is your first and most important line of defence against accidents and machine failure. Expect questions like these:
- Question: Before starting a 360 Excavator for the day, what three essential fluid levels must you check?
Answer: You must check the engine oil, coolant (water), and hydraulic fluid levels. Operating with low levels can cause catastrophic engine or system failure, leading to costly damage and dangerous situations. - Question: Why is it critical to check the condition and tension of a machine’s tracks or tyres?
Answer: For tracked machines, incorrect tension can cause excessive wear or de-tracking, leading to instability. For wheeled machines, incorrect tyre pressure affects stability, traction, and lifting capacity. Damaged tyres or tracks are a major safety hazard. - Question: A mirror on your telehandler is cracked. Why is this a reportable defect that must be fixed before use?
Answer: A cracked or dirty mirror distorts the operator’s view, making it difficult to judge distances and identify hazards in blind spots. Clear, unobstructed visibility is a legal requirement for safe operation. - Question: Where is the primary source of information for the machine’s routine lubrication points and schedule?
Answer: The manufacturer’s operator manual. This document contains all the official guidance for maintenance, safe operation, and technical specifications.
Safe Operating Principles
Once the machine is running, you must be able to operate it safely and effectively. Your understanding of stability, loads, and site awareness will be tested.
- Question: How does lifting a load affect a machine’s centre of gravity and stability?
Answer: Lifting a load raises the machine’s combined centre of gravity. The higher the centre of gravity, the less stable the machine becomes, increasing the risk of tipping over, especially on uneven ground. - Question: What is the correct procedure for travelling on a slope or incline?
Answer: Always travel straight up or down the gradient. Never travel across it, as this dramatically increases the risk of tipping. The load should be kept on the uphill side to improve stability. - Question: What is a Safe Working Load (SWL) and where can you find this information?
Answer: The SWL is the maximum load a piece of equipment can safely lift. This information is found on the machine’s capacity chart or plate, which details the SWL at various heights and radiuses. Exceeding the SWL is extremely dangerous. - Question: Name two methods for managing blind spots around your machine.
Answer: An operator should use all available mirrors and on-board cameras. Additionally, they should coordinate with a trained banksman or slinger signaller, and if necessary, stop and physically check the area before manoeuvring.
These sample questions highlight the practical knowledge required for your test. The best way to build this expertise is through high-quality, hands-on training from accredited instructors. Need training for a specific machine? View our NPORS courses.

Common Mistakes to Avoid on Test Day
Even with excellent preparation, test-day nerves can lead to simple errors. Being aware of these common pitfalls is the best way to avoid them. Remember to stay calm and methodical.
- Misreading the Question: The most common mistake. Read every single question twice, paying close attention to words like “NOT” or “ALWAYS”.
- Rushing Your Answers: You will be given sufficient time to complete the test. Use it. There are no extra points for finishing early. Take a moment to consider each option before selecting your answer.
- Ignoring ‘Obvious’ Answers: Sometimes, the simplest answer is the correct one. Health and safety principles are often based on straightforward common sense. Don’t overthink a question if the answer seems obvious.
- Last-Minute Changes: Trust your initial judgement. Only change an answer if you are absolutely certain you made a mistake. Second-guessing often leads to incorrect changes.
