Assembly and Setup

Follow these steps to assemble and prepare your pressure washer for use.

1. Attach the High-Pressure Hose: Connect one end of the 20-foot high-pressure hose to the outlet on the pressure washer unit and the other end to the gun trigger. Ensure connections are secure.
2. Connect the Gun Wand: Insert the gun wand into the gun trigger until it clicks into place.
3. Select and Attach Nozzle: Choose the desired nozzle (Turbo or 40°) and push it firmly into the end of the gun wand until it locks.
4. Connect Water Supply: Attach a standard garden hose (not included) to the water inlet on the pressure washer. Ensure the garden hose is free of kinks and has a minimum water pressure of 40-50 PSI. Turn on the water supply completely.
5. Purge Air from System: Before connecting power, squeeze the trigger on the gun to allow water to flow through the system and expel any trapped air. Continue until a steady stream of water emerges.
6. Connect Power: Plug the pressure washer's power cord into a grounded 120V AC outlet. The GFCI (Ground Fault Circuit Interrupter) on the power cord should be tested before each use by pressing the "TEST" button, then "RESET".

Maintenance

Regular maintenance ensures optimal performance and extends the life of your pressure washer.

Cleaning:

• After each use, flush the system with clean water to remove any detergent residue.
• Clean the nozzle tips regularly to prevent blockages. Use the included nozzle cleaning tool if necessary.

Storage:

• Store the pressure washer in a dry, protected area where temperatures will not fall below 0°C (32°F).
• Drain all water from the pump, hose, and spray gun before storing to prevent freezing and damage.
• Coil the high-pressure hose and power cord neatly. Store nozzles and accessories in the onboard storage.

Winterization (Cold Weather Storage):

If storing the unit in an area where temperatures may drop below freezing, proper winterization is crucial to prevent damage.

1. Disconnect all water connections.
