ASF Tools and Equipment Usage Flashcards

Which PPE item is mandatory when working with pressurized refrigerant cylinders or manifold hoses?

Answer: Safety glasses or goggles

Safety glasses or goggles protect eyes from refrigerant splashes, which can cause severe frostbite and chemical burns to eye tissue.

What is the function of a flaring tool in appliance service?

Answer: To create a conical flare on the end of copper tubing for leak-free fittings

A flaring tool compresses and forms the open end of copper tubing into a precise 45-degree cone that seals against a flare nut and fitting.

A technician is verifying ampere draw on a washing machine motor. What should the measured amperage be compared against?

Answer: The full-load amperage (FLA) listed on the motor nameplate

Comparing actual ampere draw to the nameplate FLA rating indicates whether the motor is operating normally, overloaded, or has a developing fault.

Which tool is used to deburr the inside of a freshly cut copper tube before brazing or flaring?

Answer: Reamer or deburring tool

A reamer or deburring tool smooths the internal edge left by the tubing cutter, preventing metal fragments from entering the refrigerant system and ensuring a proper seal.

What does a capacitance meter measure when testing a start capacitor on an appliance compressor?

Answer: Capacitance in microfarads (µF)

A capacitance meter measures the capacitor's ability to store charge in microfarads, which must fall within the tolerance printed on the capacitor label.

Why should a technician use an insulated-handle screwdriver when working on live appliance circuits?

Answer: To protect against electric shock if accidental contact is made with energized conductors

Insulated handles are rated for specific voltages and act as a barrier that prevents current from traveling through the tool into the technician's hand.
