2. Safety Information

Always observe basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and personal injury. Read all instructions carefully before use.

• Eye Protection: Always wear appropriate eye protection, such as safety goggles, to shield against high-pressure spray.
• Footwear: Wear sturdy, non-slip footwear to maintain balance and protect feet.
• Electrical Safety: Ensure the power outlet is grounded and suitable for outdoor use. Do not operate the pressure washer with damaged cords or plugs. Keep all electrical connections dry and off the ground.
• Water Connection: Connect the pressure washer to a cold water supply only. Do not use hot water.
