How to use

Connect the pressure washer to a domestic water supply with a standard garden hose and attach the required lance or nozzle. Plug the unit into a grounded electrical outlet and start according to the manufacturer’s instructions. Adjust the spray intensity using the lance and clean surfaces moving from top to bottom on vertical areas or with even strokes on horizontal areas. Keep a safe distance from delicate surfaces and test on a small inconspicuous area first. After use, switch off and depressurize the machine, disconnect water and power, and store accessories in the integrated compartments.

What to consider before purchase

• Intended use: best suited for domestic car-care and household cleaning rather than heavy professional use
• Storage space and on-board accessory accommodation
• Compatibility with standard garden hose fittings and household electrical outlets
• Requirement for detergent, foam lance or surface cleaner for heavy grease or large flat areas

Usage recommendations

For safe and effective results when cleaning cars and outdoor surfaces, use the adjustable lance on a lower pressure setting for painted or delicate finishes, employ the supplied detergents and surface cleaner for heavy soiling, and maintain recommended distances and even sweeping motions. Store the appliance dry and depressurized; follow the manufacturer’s maintenance guidance.
