    • Using incorrect speeds or blades/bits for the material, causing burning, tool overload, or poor finish.
    • Students often skip the pre-use check, assuming a tool is safe because it ‘looks fine’, leading to unseen damage or missing guards causing accidents.
    • Misinterpreting power tool settings—such as using a hammer drill mode for masonry on timber or setting a circular saw blade depth too shallow or too deep—leading to poor finish or kickback.
    • Failing to secure workpieces properly before operation, resulting in movement during cutting or drilling, which causes inaccuracies and potential injury.
    • Neglecting the correct sequence for inserting fastenings, e.g., not pre-drilling pilot holes for dense timber or over-tightening screws, which can split the wood or strip heads.
    • Overlooking post-work responsibilities: leaving tools dirty or unmaintained, which shortens tool life and violates health and safety requirements.
    • Failing to check the condition of power cables and plugs before use, increasing risk of electric shock.
    • Not using a push stick or appropriate guiding device when operating a bench saw, leading to potential hand injuries.
    • Selecting the wrong blade type (e.g., using a ripping blade for crosscuts) resulting in poor cut quality or binding.
    • Applying excessive force when drilling or driving fasteners, causing motor strain, bit breakage, or stripped screw heads.
    • Neglecting to disconnect the power source before changing blades, bits, or making adjustments.
    • Disposing of offcuts and sawdust without proper segregation, ignoring site waste management procedures.
    • Neglecting to inspect power cords, plugs, and casings for damage before plugging in tools.
    • Using incorrect blade types or dull cutting edges, causing burn marks, splintering, or dangerous kickback.
    • Failing to secure workpieces with clamps or vices, leading to inaccuracies and entanglement risks.
    • Omitting dust extraction or respiratory protection when cutting MDF or treated timbers.
    • Failing to consult the operator’s manual or risk assessment, leading to incorrect tool setup or use
    • Neglecting to secure the workpiece with clamps, causing movement, splintering, or inaccurate cuts
