1 Prepare safe working conditions
Unplug the tool from the outlet or remove the battery. Clean your work space, secure the object, and put on eye, hearing, and breathing protection according to the type of work.
⚠ Warning: Do not bypass safety guards, switches, and grounding. Leave electrical failures and damaged housings to professional service.
2 Determine the exact symptom
Release pressure and listen for air leaking from the outlet, connections, hose, or safety valve. Soapy water reveals small leaks.
3 Check the most common cause
Clean the intake filter and check that the tank outlet valve is completely closed. Do not disassemble the pressure switch or check valve under pressure.
4 Remove the cause without improvisation
Start the compressor and monitor the gauge only to the specified value. Continuous operation with no pressure rise requires service for valve, piston, or seals.
? Tip: Take photos of the initial state and change only one thing at a time. This way you will more easily recognize what really solved the problem.
5 Assemble and test safely
Return all guards and do a short test without load, then try on scrap material. Stop work if the tool vibrates, sparks, overheats, or makes unusual noise.
