What does the term 'dead man switch' (paddle switch) on a power tool refer to?
Answer: A trigger that must be continuously held to keep the tool running, stopping when released
A dead man or paddle switch requires constant operator pressure to keep the tool running, automatically stopping the tool if the operator loses control.
Which of the following is a sign that a drill bit needs to be replaced rather than continued in use?
Answer: The bit requires increased feed pressure and produces discolored (bluish) chips
Increased pressure requirement and heat-discolored chips indicate a dull cutting edge that wastes effort, generates heat, and can damage material.
What is the correct procedure when a power tool is not behaving normally during operation (unusual vibration, sparking, or burning smell)?
Answer: Immediately stop use, disconnect power, and have the tool inspected before further use
Abnormal tool behavior signals a potentially dangerous malfunction; stopping and isolating the tool prevents injury or fire.
When using a pneumatic nail gun, what does 'sequential firing mode' require compared to 'bump firing mode'?
Answer: The contact tip must be pressed against the work surface BEFORE each trigger pull to fire
Sequential (single-shot) mode requires the contact safety tip to engage the surface before each individual trigger pull, reducing accidental discharge risk.
What minimum clearance from underground utilities should be maintained when using a power auger for post-hole digging near utility lines?
Answer: 18 inches to 24 inches
Best practice and many regulations require maintaining 18–24 inches of clearance from utility markings because hand-digging tolerance zones apply near buried lines.
Which power tool feature is specifically designed to prevent the tool from restarting automatically after a power interruption?
Answer: Anti-restart (no-volt release) protection
Anti-restart or no-volt release protection requires the operator to manually reset the switch after power is restored, preventing unexpected startup.
A jigsaw blade that wanders off the cut line most likely indicates which of the following conditions?
Answer: The blade is dull, bent, or the wrong type for the material thickness
A dull, bent, or mismatched blade deflects under cutting pressure, causing the blade to wander rather than track the intended cut line.
