HOW TO AVOID DAMAGING SURFACES WITH YOUR RESIDENTIAL GRADE PRESSURE WASHER
Using your pressure washer to revitalize the appearance of your home and surrounding landscape can be rewarding, productive, and even fun. But there’s nothing more frustrating than accidentally using the wrong pressure washer setting and damaging the surface that you’re working so hard to clean. To prevent this, follow these guidelines from Generac:
Know the purpose of each nozzle
Each Generac pressure washer comes with an owner’s manual that details the cleaning power of each nozzle included with your residential grade pressure washer, but we’ve put together a quick overview of what each nozzle can be used for below:
Red (Blast) Nozzle: Intended for hard-to-reach areas and stubborn stains, such as second story surfaces, paint removal, oil stains, and rust (i.e. tar, gum, grease, wax, etc.).
Yellow/Green (Medium Pressure) Nozzles: Provides medium pressure and medium flow for most all-purpose cleaning tasks. These nozzles can be used when washing home siding, brick patios, wood decks, garage doors, driveways and sidewalks.
White (Low Pressure) Nozzle: Recommended for cleaning cars/trucks, boats, RV’s, patio furniture, lawn equipment, etc.
Black (Detergent) Nozzle: Only use this nozzle and pressure washer safe detergents to help break down stubborn dirt and grime on a variety of surfaces
Washers with Generac’s PowerDial™
If you own a pressure washer that features Generac’s innovative PowerDial™, it’s important to verify that the dial is set to the proper pressure level prior to cleaning. Generally speaking, lower pressure settings are recommended for cleaning cars, boats, and other scratch-sensitive surfaces, while a medium dial setting is recommended for wood surfaces such as house siding or fencing, and the heavy-duty setting is recommended for tougher surfaces like layered bricks and/or concrete.
Providing the proper amount of clearance
After placing the unit on a level surface, verify that the fuel and oil levels are correct and check all fittings for secure connections. A sufficient water supply is required for the pressure washer to operate properly, and there should be at least five feet of clearance on all sides of the machine from your desired surfaces, overhead dwellings and combustibles.
When using your pressure washer, all people and animals should be clear of the spray path. The high pressure stream of water that pressure washers produce can cut through skin and underlying tissues, which can cause serious injury.
