Which of the following checks is NOT recommended for ensuring safety regarding wheels and tyres?

When it comes to ensuring safety regarding wheels and tyres on forklifts, checking the operator's weight is not relevant. This is because the operator's weight does not have a direct impact on the condition of the wheels and tyres themselves. Instead, checks should focus on factors that directly affect the forklift's stability and performance, such as the integrity of the tyres, their pressure, and any potential rim damage.

Tyre pressure is crucial for maintaining proper traction and load capacity, while ensuring there are no missing large pieces of rubber prevents tyre blowouts or instability. Similarly, checking for rim damage is vital because damaged rims can lead to tyre failure or affect the handling of the forklift. Ensuring that all these elements are in good condition promotes safety and operational efficiency. In contrast, the operator's weight does not contribute to the mechanical integrity of the forklift’s wheels and tyres and is thus not a recommended safety check in this context.
