3. Setup
Follow these steps to set up your Ryobi AJP-75 High-Pressure Washer for first use.
- Unpacking: Carefully remove all components from the packaging. Check for any damage.
- Connect Water Supply: Attach a standard garden hose (not included) to the water inlet connector on the pressure washer. Ensure the connection is tight to prevent leaks. Turn on the water supply fully.
- Connect High-Pressure Hose: Connect one end of the high-pressure hose to the outlet on the main unit and the other end to the spray gun. Hand-tighten securely.
- Connect Spray Lance: Attach the desired spray lance or nozzle to the spray gun.
- Purge Air from System: Before connecting power, squeeze the trigger on the spray gun for approximately 30 seconds to allow water to flow through the system and expel any trapped air. This prevents damage to the pump.
- Connect Power: Plug the power cord into a grounded electrical outlet. Ensure the outlet meets the voltage requirements specified on the product label.
4. Operating Instructions
Once set up, follow these steps for safe and effective operation.
- Start the Unit: Turn the power switch to the 'ON' position. The motor will start.
- Begin Cleaning: Aim the spray gun at the surface to be cleaned, keeping a safe distance. Squeeze the trigger to start the high-pressure spray.
- Adjusting Spray: If your model includes adjustable nozzles, rotate or change the nozzle to achieve the desired spray pattern (e.g., wide fan for general cleaning, narrow jet for stubborn dirt).
- Working Method: Work from top to bottom on vertical surfaces. Keep the nozzle moving to avoid damaging the surface.
- Shutting Down: Release the spray gun trigger. Turn the power switch to the 'OFF' position. Turn off the water supply. Squeeze the trigger again to release any remaining pressure in the system. Disconnect the garden hose and power cord.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- Nozzle Cleaning: If the spray pattern becomes irregular or pressure drops, the nozzle may be clogged. Use the provided nozzle cleaning tool (if applicable) to clear any debris.
- Water Inlet Filter: Periodically check and clean the water inlet filter to prevent debris from entering the pump. Remove the filter, rinse it under running water, and reinsert.
- Hose and Cord Inspection: Regularly inspect the high-pressure hose and power cord for any signs of wear, cuts, or damage. Replace damaged components immediately.
- Winter Storage: If storing the unit in an area where temperatures may drop below freezing, drain all water from the pump, hose, and spray gun to prevent damage from freezing. Consider using a pump protector solution.
- General Cleaning: Wipe down the exterior of the unit with a damp cloth. Do not use harsh chemicals.
