1. Important Safety Information
Before operating the AIVOLT Electric Pressure Washer, please read and understand all safety warnings and instructions. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
- Eye Protection: Always wear appropriate eye protection, such as safety goggles, when operating the pressure washer.
- Keep Clear: Never direct the spray at people, pets, or electrical devices. High-pressure spray can cause severe injury.
- Electrical Safety: Ensure the power cord is connected to a properly grounded outlet. The integrated GFCI (Ground Fault Circuit Interrupter) provides leakage protection. Do not operate if the GFCI trips repeatedly.
- Water Supply: Connect the pressure washer only to a cold water supply. Do not use hot water.
- Trigger Safety System (TSS): The auto-shutoff TSS protects the pump from dry-running damage. Do not bypass this feature.
- Waterproof Rating: The unit has an IPX5 waterproof body, preventing water ingress during normal operation.
- Dual Safety Locks: Utilize the trigger lock on the spray gun and the wheel brakes for secure operation, especially in households with children or pets.
- Stable Operation: The low center of gravity and square-frame design help prevent tipping on uneven surfaces. Always operate on a stable, level ground when possible.
