Extension Cord Guidance ⚠️Extension cords are not recommended. The SPX2599-MAX includes a 35 ft GFCI power cord. If an extension cord must be used, do not use one over 25 ft, the combined cord length must not exceed 60 ft, and the extension cord must be 14 AWG or heavier. Cord Setup Requirement Built-in power cord 35 ft GFCI power cord Extension cord length Do not use over 25 ft Combined cord length Must not exceed 60 ft total Minimum extension cord gauge 14 AWG or heavier Connection type Outdoor-rated and watertight plug/socket construction Getting Started 💡 Total Stop System: The motor only runs when the trigger is operated and shuts off when the trigger is released. This is normal and helps protect the pump from overheating. Position the pressure washer Place the washer as close as possible to the water supply. Keep it upright on a secure, stable surface. Confirm the unit is switched off Make sure the On/Off switch is OFF before plugging the unit into a power outlet. Reset the GFCI if needed When first plugged in, press the Reset button until the power light indicator on the GFCI illuminates. Turn on the water completely Turn the water supply tap on completely before starting the pressure washer. Prime the system Release the safety lock and press the trigger for a few seconds until water flow is steady. This allows air to escape and releases residual pressure in the hose. Start the pressure washer Turn the On/Off switch to the ON position. When restarting the motor, keep the trigger pressed. Nozzle Guide Nozzle Recommended Use 0° Orange Spot cleaning or hard-to-reach areas. This is the most concentrated spray pattern and should only be used carefully on durable surfaces. 15° Yellow Tough cleaning jobs where a narrower high-pressure spray is needed. 40° Gray Gentler wide spray for light-duty cleaning and rinsing. Heavy-Duty Turbo Nozzle Zero-degree rotary spray that spins in a circle for a wider cleaning swath and stronger impact on durable surfaces. 🚫Never change nozzles while the trigger is engaged. Turn off the pressure washer, shut off the water, release pressure, and engage the safety lock before changing nozzles. Using the Foam Cannon 🧼Use pressure washer-rated detergent only. Do not use household detergents, bleach, chlorine products, solvents, ammonia products, acid-based products, flammable materials, or industrial-grade solutions. Remove the foam cannon bottle Gently pull the foam cannon bottle out of its storage position. Fill the bottle Remove the cap and fill or mix detergent according to the detergent instructions. Secure the cap back into place. Remove the spray wand Disconnect the spray wand from the trigger gun by pressing it in firmly and twisting clockwise until the wings release from the slot. Connect the foam cannon Press the foam cannon wings into the trigger gun slot, then twist counterclockwise until locked. Apply detergent properly Apply detergent from the bottom to the top of the dry surface. Let it remain briefly, but do not allow detergent to dry on the surface. Adjust foam if needed The foam cannon spray angle can be adjusted from 0° to 45° by rotating the nozzle. Foam volume can be adjusted using the adjustable cap. Drain and rinse after use When finished, drain and rinse the foam cannon bottle. Run the washer until all soap is drained from the bottle. ⚠️Do not adjust the foam cannon while the trigger is squeezed. Always test detergent in an inconspicuous area before use. Using the Utility Bristle Brush 🧽The included utility bristle brush is designed for painted, topcoat, and delicate surfaces. It connects directly to the trigger gun after the spray wand is removed.

Engage the safety lock Release the trigger and engage the gun safety lock. ⚠️ Taking a break? If pausing for five minutes or more, engage the gun safety lock, turn the switch OFF, and unplug the power cord. Care & Maintenance 🚫Always disconnect the power plug before inspecting, cleaning, changing accessories, or maintaining the pressure washer. 1 Clean the adapter filter Remove the adapter filter from the garden hose adapter and rinse it with warm water to prevent foreign matter from clogging the pump. 2 Clean clogged nozzles Remove the nozzle from the spray wand, use the included needle clean-out tool to clear the nozzle hole, then rinse the nozzle. 3 Inspect hoses regularly Keep hoses away from sharp objects. Replace damaged hoses and do not attempt to repair a damaged high-pressure hose. Storage + Winterizing ❄️Freeze damage is not covered by the warranty. Store the pressure washer indoors in a dry, covered, frost-free location where temperatures will not fall below 32°F / 0°C. 1 Drain before storage Always empty water from the hoses, pump, and foam cannon bottle before storing. 2 Short purge for long-term storage Disconnect all water connections, turn the pressure washer on for a few seconds until remaining water exits the pump, then turn it off immediately. 3 Avoid hose kinks Do not allow the high-pressure hose to become kinked during storage. 4 Use pump protection for winter storage Use a non-corrosive/non-toxic antifreeze, pump saver, or pump protector before winter storage. 5 Flush before reuse Before reusing after antifreeze or pump protector, completely flush the unit with clear water.
