here are some tips to ensure longevity of the unit. Always unplug your pressure washer before any maintenance.
1. Clean the nozzle. Regularly check and clean your pressure washer nozzle to remove debris that can affect water pressure and spray pattern, soak in a vinegar solution if necessary.
2. Drain excess water. After each use, run the pressure washer for a brief period with the trigger pulled to clear any remaining water from the system.
3. Check for leaks. Inspect all connections, including the hose, wand, and nozzle, for any signs of leaks and tighten as needed.
4. Use appropriate detergent. If using a cleaning solution, choose a pressure washer-safe detergent and follow the manufacturer's instructions for mixing and application.
Important points to remember.
1. Do not use hot water. Greenworks pressure washers are designed for cold water use only.
2. Avoid harsh chemicals. Never use bleach, ammonia, or other corrosive chemicals in your pressure washer as they can damage the internal components.
3. Check the water intake filter. Regularly check and clean the water intake filter to prevent clogs.
