Important Safety Instructions
When using this electric pressure washer, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. Always adhere to these guidelines:
- Read All Instructions: Familiarize yourself with the controls and proper use of the pressure washer.
- Grounding Instructions: This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
- Avoid Unintentional Starting: Ensure the switch is in the OFF position before connecting to a power source or picking up or carrying the appliance.
- Keep Area Clear: Keep the operating area clear of all persons, especially children and pets.
- Wear Safety Gear: Always wear appropriate eye protection, such as safety goggles, and protective clothing.
- Do Not Direct Spray at People or Animals: High-pressure spray can cause serious injury.
- Use Proper Extension Cords: If an extension cord is used, ensure it is suitable for outdoor use and rated for the appliance's amperage.
- Disconnect Power: Always disconnect the power cord from the outlet when not in use or before performing any maintenance.
Product Components
The Sun Joe SPX2599-MAX Electric Pressure Washer includes several key components for effective cleaning:
- Main Pressure Washer Unit
- High-Pressure Hose (20 feet)
- Spray Wand with Trigger Gun
- Quick-Connect Nozzles (0°, 15°, 40°)
- Onboard 1-Liter Foam Cannon

Setup Instructions
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect for any damage.
- Assemble Handle: Attach the handle to the main unit if it is not pre-assembled, securing it with the provided hardware.
- Connect High-Pressure Hose: Connect one end of the high-pressure hose to the pressure washer's high-pressure outlet and the other end to the trigger gun. Ensure connections are tight.
- 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 diameter of 1/2 inch. Turn on the water supply fully.
- Purge Air from System: Before connecting to 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.
- Connect Power: Plug the GFCI-protected power cord into a grounded 120V AC electrical outlet. Press the RESET button on the GFCI plug.
Operating Instructions
1. Starting the Pressure Washer
- Ensure the water supply is fully open and the power cord is connected.
- Turn the ON/OFF switch to the 'ON' position. The motor will start.
- Squeeze the trigger gun to begin spraying. The Total Stop System (TSS) will automatically shut off the pump and power when the trigger is not engaged, saving energy and prolonging pump life.
2. Using Quick-Connect Nozzles
The SPX2599-MAX comes with three quick-connect nozzles to customize your spray for various cleaning tasks:

- 0° (Red): For pinpoint cleaning and hard-to-reach areas. Use with extreme caution due to its intense pressure.
- 15° (Yellow): For intense cleaning of stubborn stains on hard surfaces.
- 40° (Green): For general cleaning and delicate surfaces.
To change nozzles, ensure the pressure washer is off and the trigger gun is locked. Pull back the collar on the spray wand, insert the desired nozzle, and release the collar to lock it in place. Tug on the nozzle to ensure it is securely seated.
