First, prepare the machine. Place the electric high-pressure washer on a stable, dry surface, ensuring the inlet and outlet connections are tight and leak-free. Also, check the power cord for damage, a secure power connection, and proper grounding to prevent electric shock.
Next, adjust the spray gun. Select the appropriate spray mode and pressure level based on the level of dirt on the object being cleaned. For light dirt, choose a lower pressure and a fan-shaped spray pattern to cover a wider cleaning area; for stubborn dirt, increase the pressure and switch to a direct spray mode for enhanced cleaning power.
When starting, slowly turn on the power switch to avoid a sudden surge of current that could damage the machine. After starting, allow the machine to idle for 30 seconds to 1 minute to allow the pressure system to stabilize. Simultaneously, observe the machine for any abnormal vibrations or noises; if any abnormalities are detected, stop the machine immediately and inspect it.
During cleaning operations, hold the spray gun steadily and move it evenly to avoid over-spraying in certain areas. Also, prioritize your own safety and avoid pointing the spray nozzle at yourself or others. For objects made of different materials, adjust the appropriate pressure and spray pattern to prevent surface damage.
After use, first turn off the power switch, then slowly close the water inlet valve to allow the internal pressure of the cleaner to gradually release. Once the pressure has completely released, store the cleaner properly in a dry, well-ventilated place, avoiding impacts and moisture.
