  1. When using a circular saw, what is the correct direction to move the saw relative to the blade rotation?

    Answer: Feed the saw so the blade rotation pulls the saw forward into the cut

    Feeding the saw so blade rotation pulls it forward into the cut provides a controlled, stable cut and reduces kickback risk.

  2. What is the primary purpose of a torque limiting clutch on a power drill/driver?

    Answer: To prevent overdriving fasteners and protect the motor from overload

    A torque limiting clutch disengages drive when a preset torque is reached, preventing stripped screws and motor damage.

  3. Which grinder wheel marking indicates it is NOT safe for side grinding operations?

    Answer: Type 1 (straight wheel)

    Type 1 straight wheels are rated for peripheral (edge) grinding only and must never be used for side grinding.

  4. What RPM rating check must be performed before mounting any abrasive wheel on a grinder?

    Answer: Wheel RPM rating must equal or exceed the grinder's maximum no-load RPM

    The wheel's maximum RPM rating must meet or exceed the grinder's no-load speed to prevent catastrophic wheel failure.

  5. A reciprocating saw blade designed for cutting metal will have how many teeth per inch (TPI) compared to a wood-cutting blade?

    Answer: More TPI (e.g., 18-24 TPI)

    Metal-cutting reciprocating saw blades use higher TPI (18-24) to prevent tooth stripping and produce cleaner cuts in hard materials.

  6. Before performing blade changes or adjustments on a power saw, what is the FIRST action the installer must take?

    Answer: Disconnect the power source — unplug cord or remove battery

    Disconnecting power first is the mandatory lockout/tagout step before any blade change, regardless of other precautions taken.

  7. When drilling into an overhead surface, which PPE item is MOST critical beyond safety glasses?

    Answer: A hard hat or bump cap to protect the head from falling debris

    Overhead drilling sends chips and debris downward toward the driller's head, making head protection essential in addition to eye protection.
