4. Setup and Assembly
Follow these steps to assemble and prepare your pressure washer for use:
- Attach the High-Pressure Hose: Connect the 25-foot high-pressure hose to the outlet on the pressure washer unit and to the trigger gun. Ensure connections are secure to prevent leaks.
- Connect the Water Supply: Attach a standard garden hose (not included) to the brass garden hose adapter, then connect the adapter to the water inlet on the pressure washer. Ensure the water supply is turned on fully before starting the unit.
- Connect the Power Cord: Plug the pressure washer's power cord into a grounded 120-volt, 13-amp electrical outlet. The unit features an auto-reset GFCI for safety.
- Install the Lance and Nozzle: Attach the metal lance to the trigger gun. Select the desired quick-connect nozzle (0°, 15°, 25°, or 40°) and insert it into the end of the lance until it clicks securely into place.
- Fill the Foam Cannon (Optional): If using the foam cannon, fill it with appropriate pressure washer detergent and attach it to the trigger gun.

5. Operating Instructions
- Purge Air from the System: Before turning on the power, squeeze the trigger gun to allow water to flow through the system and expel any trapped air. Continue until a steady stream of water emerges.
- Start the Pressure Washer: Turn the ON/OFF switch to the "ON" position. The motor will start, and the pump will build pressure.
- Begin Cleaning: Squeeze the trigger gun to start the high-pressure spray. Release the trigger to engage the "Auto On/Off Total Stop Feature," which automatically shuts off the pump when the trigger is not engaged, saving energy and extending pump life.
- Change Nozzles: To change nozzles, release the trigger, turn off the unit, and disconnect the nozzle from the lance. Insert the new nozzle until it clicks into place.
- Using the Foam Cannon: Attach the foam cannon to the trigger gun. The foam cannon mixes detergent with the high-pressure water to create a thick foam for cleaning.
Nozzle Selection Guide:
- 0-degree (Red): Pinpoint jet for intense cleaning of small, stubborn areas. Use with extreme caution.
- 15-degree (Yellow): Narrow fan for aggressive cleaning of hard surfaces.
- 25-degree (Green): Medium fan for general cleaning of most surfaces.
- 40-degree (White): Wide fan for gentle cleaning of delicate surfaces.

6. Maintenance and Storage
Proper maintenance ensures longevity and optimal performance of your pressure washer.
- After Each Use:
- Turn off the pressure washer and disconnect the power.
- Turn off the water supply.
- Squeeze the trigger gun to release any remaining pressure in the system.
- Disconnect the garden hose and high-pressure hose.
- Drain any remaining water from the pump and hoses.
- Cleaning Nozzles: If nozzles become clogged, use a small wire or needle to clear debris from the nozzle opening.
- Storage: Store the pressure washer in a dry, frost-free area. The extendable telescoping handle and on-board storage options for the trigger gun, foam cannon, high-pressure hose, and power cord facilitate compact storage.
- Winterization: In cold climates, it is crucial to winterize the unit to prevent damage from freezing. Consult the full product manual for detailed winterization procedures.
