Introdução

This guide shows you how to operate, clean, and maintain common electric power tools so they stay safe, reliable, and ready for years of service. You will learn essential safety checks, routine care, and troubleshooting tips for a phase tester, multimeter, cordless drill-driver, bench grinder, and shop compressor. Following these practices supports responsible ownership and the circular economy by extending each tool’s life and reducing waste.

O que você precisa

Passo 1 Prepare a safe workspace

Disconnect the power cord or remove the battery before any inspection, cleaning, or adjustment.
Work on a clean, dry surface with adequate lighting while wearing safety glasses and protective gloves.

Passo 2 Phase tester

Push the metal probe of the phase tester into the socket contact and lightly touch the cap to close the circuit.
A glowing lamp confirms live phase; no light indicates neutral or a fault in the outlet.
Use the tool to rule out a faulty socket before dismantling any appliance that will not power on.
Tighten or release wire clamps evenly with the tester’s flat-blade tip during wiring work.

Passo 3 Multimeter

Insert the black lead into the COM jack and the red lead into the correct jack for voltage, resistance, or current.
Select a measurement range higher than the expected value, for example 700 V for 240 V mains, to avoid meter damage.
Use the high-current jack only for brief current tests through the internal fuse.
Switch to continuity mode and listen for the buzzer to locate broken cables or confirm a good connection.
Misplaced leads or a wrong range can short the circuit and burn the meter, so double-check before probing.
Store the multimeter manual and abbreviations chart near the bench for quick reference.

Passo 4 Cordless drill-driver

Unplug the charger once the battery reaches full capacity; never leave packs on charge overnight to prevent fires.
Fit the correct bit or accessory for the job, from screwdriving tips to wire brushes or polishing pads.
Slide the direction switch to reverse for removal and forward for tightening fasteners.
Set low speed for driving and high speed for drilling, matching clutch torque to the material to avoid stripping threads.
Start with the lowest clutch setting when driving screws into plastic or soft material and increase only if needed.
Select drill bits made for wood, metal, masonry, or plastic and beware of hot chips that can burn fingers.
Choose a drill that balances well in your hand and offers enough amp-hour capacity for continuous work.

Passo 5 Bench grinder and rotary tool

Set the bench grinder to low RPM when working on plastic or heat-sensitive parts to prevent melting.
Keep the grinding wheel flat by dressing it with the supplied stone before precision sharpening.
Use the opposite wheel or a cloth buff for polishing aluminum and other non-ferrous pieces.
Always wear approved safety goggles or a face shield to block sparks and flying debris.
Attach the proper bit, burr, or brush on the rotary tool and match speed and abrasive to the material.
Read each accessory’s instructions because usage varies between cutting, grinding, and polishing attachments.

Passo 6 Compressor

Fit the long blower nozzle to access tight areas and blast dust from motors, fans, or circuit boards.
Clip on the tire inflator or spray gun if needed and check the built-in gauge to monitor pressure.
Test paint or cleaner flow on scrap paper and adjust the regulator knob until the pattern meets your needs.
Reduce pressure for delicate electronics to avoid damage and make the coupler easier to connect.
When finished, empty the tank and open the drain valve to release condensation and prevent internal rust.
Store the compressor in a dry area and remember it is noisy during refill cycles.

Conclusão

Regular cleaning, correct settings, and safe handling keep your power tools working efficiently and out of the waste stream. Refer back to this guide, read every manual, and stay connected with the repair community to extend the life of your equipment and support a more circular economy.
