Question

technician a says that the cutting head slide adjustment should be left loose while cutting to allow the cutting head to center itself as it completes the cut. technician b says that the chip deflector/silencer is only needed when the rotor is larger than 15 inches in diameter. who is correct?
technician a
technician b
both technician a and technician b
neither technician a nor technician b

Explanation:

The cutting - head slide adjustment should be tightened during cutting to ensure accuracy and stability, so Technician A is incorrect. The need for a chip deflector/silencer is not solely determined by the rotor diameter of 15 inches, and there are other factors at play, so Technician B is incorrect.

Answer:

Neither Technician A nor Technician B
