4. Hose Connection: Connect the 50-foot Uberflex® non-marking hose to the pump outlet and the spray gun. Ensure connections are tight to prevent leaks.

Operating Instructions

Follow these steps for safe and effective operation of your pressure washer:

1. Prepare the Area: Clear the work area of any obstacles or items that could be damaged by high-pressure water.
2. Connect Water Supply: Ensure the garden hose is fully connected and the water faucet is turned on completely.
3. Purge Air: Squeeze the trigger on the spray gun to purge air from the pump and hose until a steady stream of water flows out. This also engages the Easy Start feature, preventing pressure buildup for smoother recoil pulling.
4. Start the Engine: Follow the engine manufacturer's instructions for starting. The NorthStar e420 engine with EFI technology ensures reliable starting.
5. Select Nozzle: Choose the appropriate quick-connect nozzle for your cleaning task. Different nozzles provide varying spray patterns and pressure levels.
6. Begin Cleaning: Hold the spray gun firmly and aim at the surface to be cleaned. Maintain a safe distance to avoid damage to the surface.
7. Applying Detergent (Optional): If using detergent, ensure it is compatible with pressure washers. Use the built-in downstream chemical injector for application.
8. Shut Down: When finished, turn off the engine, then turn off the water supply. Squeeze the spray gun trigger to release any remaining pressure in the system.
