1. Important Safety Information
Please read and understand all safety warnings and instructions before operating this cordless power washer. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
General Safety Warnings
- Personal Safety: Always wear appropriate personal protective equipment, including safety glasses, gloves, and protective footwear. Do not operate the power washer while barefoot or wearing open-toed shoes. Keep children and bystanders away from the operating area.
- Electrical Safety: Use only the charger supplied by the manufacturer to recharge the battery. Do not expose the power washer to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Battery Use and Care: This appliance contains batteries that are only rechargeable by the supplied charger. Do not dispose of batteries in a fire. They may explode. Check with local codes for possible special disposal instructions. Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
- High Pressure Hazard: The high-pressure jet can be dangerous if misused. Do not direct the jet at persons, pets, electrical devices, or the unit itself. Never point the nozzle at yourself or others.
- Water Source: Ensure your water source is clean and free of debris to prevent damage to the pump. Use the included water filter.
- Stability: Ensure you have stable footing when operating the power washer. The recoil force from the water jet can cause you to lose balance.
